2020-02-22Remove tui_delete_invisible_windows and tui_make_all_invisibleTom Tromey1-9/+0
tui_delete_invisible_windows is only needed after applying a layout, and tui_make_all_invisible is only needed before applying a layout. This patch removes these functions, in favor of doing this management directly in tui_apply_current_layout. This is needed so that the lifetimes of non-built-in windows will be properly managed. gdb/ChangeLog 2020-02-22 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_all_invisible): Don't declare. * tui/tui-wingeneral.c (tui_make_all_invisible): Remove. * tui/tui-win.c (tui_resize_all): Don't call tui_delete_invisible_windows. * tui/tui-layout.c (tui_apply_current_layout): Delete windows when done.

2020-01-19Remove flickering from the TUITom Tromey1-2/+44
In some cases, the TUI flickers when redrawing. This can be seen mostly easily when switching layouts. This patch fixes the problem by exploiting the double buffering that curses already does. In some spots, the TUI will now disable flushing the curses buffers to the screen; and then flush them all at once when the rendering is complete. gdb/ChangeLog 2020-01-19 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_show_assembly): Use tui_suppress_output. * tui/tui-wingeneral.h (class tui_suppress_output): New.

2020-01-13gdb/tui: Place window titles in the center of the borderAndrew Burgess1-2/+2
In tui-wingeneral.c:box_win () a comment suggest we should display titles like this: +-WINDOW TITLE GOES HERE-+ However, we actually display them like this: +--WINDOW TITLE GOES HERE+ The former seems nicer to me, so that's what this commit does. Short titles will appear as: +-SHORT TITLE------------+ We previously didn't test the horizontal windows borders in the test suite, however, I've updated things so that we do now check for the '+-' and '-+' on the upper border, this will give us some protection. gdb/ChangeLog: * tui/tui-wingeneral.c (box_win): Position the title in the center of the border. gdb/testsuite/ChangeLog: * lib/tuiterm.exp (Term::_check_box): Check some parts of the top border.

2020-01-11Make TUI borders respect "set style enabled"Tom Tromey1-3/+4
When adding support for styling the TUI borders, I neglected to have this code check cli_styling. As a result, "set style enabled off" does not affect the borders. This patch fixes this oversight. While doing this, I found that running gdb without an executable, enabling the TUI, and then trying "set style enabled off" would fail with the mysterious "No registers". The fix for this is to use deprecated_safe_get_selected_frame in tui_source_window_base::refill. gdb/ChangeLog 2020-01-11 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (box_win): Check cli_styling. * tui/tui-winsource.c (tui_source_window_base::refill): Use deprecated_safe_get_selected_frame.

gdb/ChangeLog: Update copyright year range in all GDB files.
2019-12-11Remove struct tui_pointTom Tromey1-1/+1
struct tui_point does not help very much. It is only used for storage, and never passed between functions. I think it makes the code more verbose without any corresponding benefit, so this patch removes it. gdb/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_gen_win_info::make_window): Update. * tui/tui-win.c (tui_adjust_win_heights, tui_resize_all): Update. * tui/tui-layout.c (tui_gen_win_info::resize): Update. * tui/tui-data.h (struct tui_point): Remove.

2019-12-01Add TUI border colorsTom Tromey1-0/+8
This adds the ability to change the color of the TUI borders, both ordinary and active. Unlike other styling options, this doesn't allow setting the intensity, because that is already done by the TUI in a different way. gdb/ChangeLog 2019-12-01 Tom Tromey <tom@tromey.com> * NEWS: Document new settings. * tui/tui-wingeneral.c (box_win): Apply appropriate border style. * tui/tui-win.c (_initialize_tui_win): Add border style observers. * tui/tui-io.h (tui_apply_style): Declare. * tui/tui-io.c (tui_apply_style): Rename from apply_style.

2019-11-10Remove can_highlight from TUI windowsTom Tromey1-3/+3
Each TUI window has a "can_highlight" member. However, this has the same meaning as "can_box" -- a window can be highlighted if and only if it can be boxed. So, this patch removes can_highlight in favor of simply using can_box. gdb/ChangeLog 2019-11-10 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_unhighlight_win): Use can_box. (tui_highlight_win): Likewise. (tui_win_info::check_and_display_highlight_if_needed): Likewise. * tui/tui-data.h (struct tui_win_info) <can_highlight>: Remove. * tui/tui-command.h (struct tui_cmd_window) <tui_cmd_window>: Don't set can_highlight.

2019-10-09Make TUI window handle a unique_ptrTom Tromey1-17/+5
This changes tui_gen_win_info::handle to be a specialization of unique_ptr. This is perhaps mildly uglier in some spots, due to the proliferation of "get"; but on the other hand it cleans up some manual management and it allows for the removal of tui_delete_win. gdb/ChangeLog 2019-10-09 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_delete_win): Don't declare. * tui/tui-stack.c (tui_locator_window::rerender): Update. * tui/tui-command.c (tui_cmd_window::resize) (tui_refresh_cmd_win): Update. * tui/tui-win.c (tui_resize_all, tui_set_focus_command): Update. * tui/tui.c (tui_rl_other_window, tui_enable): Update. * tui/tui-data.c (~tui_gen_win_info): Remove. * tui/tui-layout.c (tui_gen_win_info::resize): Update. * tui/tui-io.c (update_cmdwin_start_line, tui_putc, tui_puts) (tui_redisplay_readline, tui_mld_flush) (tui_mld_erase_entire_line, tui_mld_getc, tui_getc): Update. * tui/tui-regs.c (tui_data_window::delete_data_content_windows) (tui_data_window::erase_data_content) (tui_data_item_window::rerender) (tui_data_item_window::refresh_window): Update. * tui/tui-wingeneral.c (tui_gen_win_info::refresh_window) (box_win, tui_gen_win_info::make_window) (tui_gen_win_info::make_visible): Update.

2019-09-20Remove separator comments from TUITom Tromey1-9/+0
This removes various separator comments from the TUI. These aren't used elsewhere in gdb, and they were incorrect in some cases as well. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-data.c: Remove separator comments. * tui/tui-layout.c: Remove separator comments. * tui/tui-win.c: Remove separator comments. * tui/tui-wingeneral.c: Remove separator comments.
2019-09-08Truncate long TUI window titlesTom Tromey1-1/+15
If a TUI window has a long title, it can overflow the title line. This changes the TUI to use just the tail part of the title in this case. gdb/ChangeLog 2019-09-08 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (box_win): Truncate long window titles. gdb/testsuite/ChangeLog 2019-09-08 Tom Tromey <tom@tromey.com> * gdb.tui/resize.exp: Remove setup_xfail. * gdb.tui/regs.exp: Remove setup_xfail. * gdb.tui/basic.exp: Remove setup_xfail.
2019-08-30Don't call touchwin in tui_gen_win_info::refresh_windowTom Tromey1-4/+1
The call to touchwin in tui_gen_win_info::refresh_window was an artifact of some earlier refactorings. Testing shows it isn't needed any more -- I believe it was only ever needed for the data item window display problem; but that's been solved more locally. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_gen_win_info::refresh_window): Don't call touchwin.
2019-08-30Remove NULL checks from box_winTom Tromey1-19/+16
box_win can't be called with a NULL window, or with an invisible window. So, the NULL checks in that function can be removed. gdb/ChangeLog 2019-08-30 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (box_win): Assume win_info and win_info->handle cannot be NULL.
2019-08-20Remove some defines from tui-data.hTom Tromey1-5/+5
This removes the HILITE and NO_HILITE defines from tui-data.h, in favor of simply passing a bool to box_win. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (box_win): Change type of highlight_flag. (tui_unhighlight_win, tui_highlight_win) (tui_win_info::make_window): Update. * tui/tui-data.h (HILITE, NO_HILITE): Remove.
2019-08-20Change tui_make_window to be a methodTom Tromey1-17/+14
I combined several small changes into one patch here. I believe I started by noticing that the "title" is not needed by tui_gen_win_info and could be self-managing (i.e. std::string). Moving this revealed that "can_box" is also a property of tui_win_info and not tui_gen_win_info; and this in turn caused the changes to tui_make_window and box_win. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_window): Don't declare. * tui/tui-wingeneral.c (box_win): Change type of win_info. (box_win): Update. (tui_gen_win_info::make_window): Rename from tui_make_window. (tui_win_info::make_window): New method. (tui_gen_win_info::make_visible): Update. * tui/tui-source.c (tui_source_window::set_contents): Update. * tui/tui-regs.c (tui_data_window::show_register_group): Update.

2019-08-16Remove separate visibility flagTom Tromey1-5/+3
TUI windows keep track of their visibility in a boolean field. However, this is not needed, because a window is visible if and only if it has an underlying curses handle. So, we can remove this separate field. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_is_window_visible): Update. * tui/tui-wingeneral.c (tui_make_window) (tui_gen_win_info::make_visible, tui_refresh_all): Update. * tui/tui-win.c (window_name_completer, tui_refresh_all_win) (tui_set_focus_command, tui_all_windows_info, update_tab_width) (tui_set_win_height_command, parse_scrolling_args): Update. * tui/tui-source.c (tui_source_window::style_changed): Update. * tui/tui-regs.c (tui_show_registers) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_check_register_values, tui_reg_command): Update. * tui/tui-disasm.c (tui_show_disassem): Update. * tui/tui-data.h (struct tui_gen_win_info) <is_visible>: New method. <is_visible>: Remove field. * tui/tui-data.c (tui_next_win, tui_prev_win) (tui_delete_invisible_windows): Update.
2019-08-15Move locator code to tui-stack.cTom Tromey1-0/+1
The locator is mostly implemented in tui-stack.c. This moves the remaining bits to tui-stack.c and tui-stack.h, as appropriate. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c: Include tui-stack.h. * tui/tui-stack.h (MAX_LOCATOR_ELEMENT_LEN) (struct tui_locator_window): Move from tui-data.h. * tui/tui-stack.c (_locator, tui_locator_win_info_ptr) (tui_initialize_static_data): Move from tui-data.c. * tui/tui-data.h (MAX_LOCATOR_ELEMENT_LEN) (struct tui_locator_window): Move to tui-stack.c. * tui/tui-data.c (_locator, tui_locator_win_info_ptr) (tui_initialize_static_data): Move to tui-stack.c.
2019-08-15Simplify TUI boxingTom Tromey1-4/+3
In the TUI, whether or not a window can be boxed is a property of the window's type. This adds a can_box method to the window classes, and changes tui_make_window to defer to this, removing the "box_it" paramter. This also lets us remove "enum tui_box", as it is no longer used. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_window): Update. * tui/tui-wingeneral.c (tui_make_window): Remove "box_it" parameter. (tui_gen_win_info::make_visible): Update. * tui/tui-regs.c (tui_data_window::display_registers_from): Update. * tui/tui-layout.c (show_source_disasm_command) (show_source_or_disasm_and_command): Update. * tui/tui-data.h (struct tui_gen_win_info) <can_box>: New method. (enum tui_box): Remove. (struct tui_win_info) <can_box>: New method. * tui/tui-command.h (struct tui_cmd_window) <can_box>: New method.
2019-08-13Change tui_check_and_display_highlight_if_needed to be a methodTom Tromey1-6/+5
This changes tui_check_and_display_highlight_if_needed to be a method on tui_win_info. This makes it clear that the NULL check in that function is not needed, so it is removed here. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_erase_source_content) (tui_show_source_content, tui_source_window_base::refresh_all): Update. * tui/tui-wingeneral.h (tui_check_and_display_highlight_if_needed): Don't declare. * tui/tui-wingeneral.c (tui_win_info::check_and_display_highlight_if_needed): Rename from check_and_display_highlight_if_needed. * tui/tui-win.c (tui_rehighlight_all) (tui_win_info::make_visible_with_new_height): Update. * tui/tui-regs.c (tui_data_window::display_registers_from_line) (tui_data_window::erase_data_content) (tui_data_window::display_all_data): Update. * tui/tui-data.h (struct tui_win_info) <check_and_display_highlight_if_needed>: Declare.
2019-08-13Simplify tui_make_all_invisibleTom Tromey1-9/+3
This simplifies the implementation of tui_make_all_invisible. Also, because show_data is only called by show_layout, this hoists the call to tui_make_all_invisible and removes the call from show_data. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (make_all_visible): Remove. (tui_make_all_invisible): Simplify. * tui/tui-layout.c (tui_make_all_invisible): Move from tui-wingeneral.c; simplify. (show_layout): Hoist call to tui_make_all_invisible. (show_data): Don't call tui_make_all_invisible.
2019-08-13Remove tui_make_all_visibleTom Tromey1-6/+0
The function tui_make_all_visible is not used, so remove it. gdb/ChangeLog 2019-08-13 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_all_visible): Don't declare. * tui/tui-wingeneral.c (tui_make_all_visible): Remove.
2019-07-17Remove unnecessary "return"sTom Tromey1-1/+0
The TUI has some "return;" statements at the end of void-returning functions. There's no need for these, so this patch removes them. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_window) (tui_update_source_window_as_is) (tui_update_source_windows_with_line): Remove return. * tui/tui-disasm.c (tui_show_disassem) (tui_show_disassem_and_update_source): Remove return. * tui/tui.c (tui_reset): Remove return. * tui/tui-wingeneral.c (tui_check_and_display_highlight_if_needed): Remove return.
2019-07-17Move source window common to code to tui-winsource.[ch]Tom Tromey1-18/+0
Like the previous rearranging patches, this moves the source and disassembly window base class code to tui-winsource.[ch]. The execution info window is also moved, because it is associated with this base class. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_exec_info_window) (struct tui_source_window_base): Move from tui-data.h. * tui/tui-winsource.c: Move many method definitions from elsewhere.

(struct tui_source_window_base): Likewise. * tui/tui-data.c (tui_source_window_base::clear_detail) (tui_source_window_base, ~tui_source_window_base): Move to tui-winsource.c.
2019-07-17Rearrange TUI data window codeTom Tromey1-13/+0
An earlier patch caused tui-windata.h to be essentially empty. And, other earlier patches implemented TUI data window methods in any spot that happened to be convenient at the time. This patch rearranges all the data window code to be somewhat more organized. It moves tui_data_window to tui-regs.h, and moves the implementation of all methods to tui-regs.c. It then removes tui-windata.h and tui-windata.c. It also removes the "structuring" comments from tui-regs.c; these are not the usual gdb style, and were out of date anyhow. Finally, it moves _initialize_tui_regs to the end of the file, per the usual gdb convention. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui.c: Update. * tui/tui-wingeneral.c (tui_data_window::refresh_window): Move to tui-regs.c. * tui/tui-windata.h: Remove file. * tui/tui-windata.c: Remove file. * tui/tui-win.c (tui_data_window::set_new_height) (tui_data_window::do_make_visible_with_new_height): Move to tui-regs.c. * tui/tui-regs.h (struct tui_data_window): Move from tui-data.h. * tui/tui-regs.c: Remove "structuring" comments.

2019-07-17Remove tui_make_visible and tui_make_invisibleTom Tromey1-12/+0
tui_make_visible and tui_make_invisible are just wrappers for a method call, so remove them and have the callers simply make the method call themselves. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_visible, tui_make_invisible): Don't declare. * tui/tui-wingeneral.c (tui_make_visible, tui_make_invisible): Remove. * tui/tui-win.c (tui_source_window_base::set_new_height) (tui_source_window_base::set_new_height) (make_invisible_and_set_new_height) (tui_source_window_base::do_make_visible_with_new_height) (tui_source_window_base::do_make_visible_with_new_height): Update. * tui/tui-layout.c (show_source_disasm_command, show_data) (show_source_or_disasm_and_command): Update. * tui/tui-layout.c (show_layout): Update.
2019-07-17Simplify tui_gen_win_info::make_visibleTom Tromey1-12/+7
I noticed that tui_gen_win_info::make_visible was much wordier than it needed to be. This simplifies it. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_gen_win_info::make_visible): Simplify.
2019-07-17Always create an execution info window for a source windowTom Tromey1-2/+1
A source or disassembly window will always have an "execution info" window (the window along the side that displays breakpoint info), but this isn't immediately clear from the source. As a result, some code has checks to see whether the execution_info is NULL. This changes the source window base class to always instantiate an execution_info window, then updates the rest of the code. It also simplifies window creation in tui-layout.c. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_set_exec_info_content): Remove condition. * tui/tui-wingeneral.c (tui_source_window_base::make_visible): Remove condition. * tui/tui-source.c (tui_source_window_base::reset): New method. * tui/tui-layout.c (make_command_window): Don't call init_and_make_win.

2019-07-17Remove TUI data window special caseTom Tromey1-9/+6
The TUI has a couple of special cases for updating the data window: one in tui_rl_other_windowand one in tui_set_focus_command. As part of the project to remove references to globals, I wanted to remove these calls; but when I did, some simple operations (like "C-x o") would cause the register window to blank. This fixes the underlying problem by arranging for the data window's refresh_window method to call the superclass method first, and then to refresh the child windows. Then the special cases can be removed. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_rl_other_window): Update. * tui/tui-wingeneral.c (tui_data_window::refresh_window): Call superclass method first. Always iterate over regs_content. (tui_unhighlight_win, tui_highlight_win): Use refresh_window method. * tui/tui-win.c (tui_set_focus_command): Update.
2019-07-17Merge refresh and refresh_window methodsTom Tromey1-22/+11
Earlier refactorings introduced the refresh and refresh_window methods, following the previous TUI code. However, these methods are essentially the same, so this patch merges them. It also removes some redundant refresh_window calls, because the execution window is updated automatically by the corresponding source (or disassembly) window. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_show_exec_info_content): Don't call refresh_window. * tui/tui-wingeneral.c (tui_gen_win_info::refresh_window): Call touchwin. (tui_data_window::refresh_window): Call refresh_window on data items. Always call superclass refresh_window. (tui_win_info::refresh): Remove. (tui_source_window_base::refresh_window): Update. (tui_refresh_all): Update. * tui/tui-layout.c (show_source_disasm_command): Remove call to refresh_window. (show_source_or_disasm_and_command): Likewise. * tui/tui-data.h (struct tui_win_info) <refresh>: Remove. (struct tui_source_window_base) <refresh>: Likewise.
2019-07-17Introduce TUI window iteratorTom Tromey1-14/+6
This introduces an iterator class and a range adapter to make it simpler to iterate over TUI windows. One explicit iteration remains, in tui-win.c, because that spot is deleting windows as well. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_refresh_all): Update. * tui/tui-wingeneral.c (make_all_visible): Use foreach. (tui_refresh_all): Remove "list" parameter. Use foreach. * tui/tui-win.c (window_name_completer): Use foreach. (tui_refresh_all_win, tui_rehighlight_all, tui_all_windows_info) (update_tab_width): Likewise. * tui/tui-layout.c (show_layout): Update. * tui/tui-data.h (class tui_window_iterator): New. (struct all_tui_windows): New. * tui/tui-data.c (tui_partial_win_by_name): Use foreach.
2019-07-17Check can_highlight in tui_check_and_display_highlight_if_neededTom Tromey1-1/+1
tui_check_and_display_highlight_if_needed currently checks the window's type; but this can be replaced with a check of "can_highlight", making it more polymorphically-correct. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_check_and_display_highlight_if_needed): Check can_highlight.
2019-06-25Tidy tui_delete_winTom Tromey1-2/+0
tui_delete_win does its own NULL check, so ~tui_gen_win_info does not need to do it. Also, tui_delete_win has an extraneous "return". gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_delete_win): Remove "return". * tui/tui-data.c (~tui_gen_win_info): Remove "if".
2019-06-25Fix "auxiliary" typoTom Tromey1-1/+1
The TUI has a function called tui_win_is_auxillary, but the word should actually be spelled "auxiliary". This fixes the typo. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_gen_win_info::make_visible): Update. * tui/tui-win.c (make_invisible_and_set_new_height): Update. * tui/tui-layout.c (init_and_make_win): Update. * tui/tui.h (enum tui_win_type): Update. * tui/tui-data.h (tui_win_is_auxiliary): Rename from tui_win_is_auxillary. * tui/tui-data.c (tui_win_is_auxiliary): Rename from tui_win_is_auxillary.
2019-06-25Separate out data windowTom Tromey1-8/+4
This removes "data_window" from union tui_which_element and updates the uses. It also changes how tui_data_window refers to the register data, and changes it not to need the "content" field at all (though as this is in a base class, it can't yet be removed). gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_data_window::refresh_window): Update. * tui/tui-windata.c (tui_data_window::first_data_item_displayed) (tui_delete_data_content_windows, tui_display_all_data) (tui_data_window::do_scroll_vertical, tui_display_data_from): Update. * tui/tui-win.c (tui_data_window::set_new_height): Simplify. * tui/tui-regs.c (tui_last_regs_line_no) (tui_line_from_reg_element_no, tui_first_reg_element_no_inline) (tui_show_registers): Update.

(tui_display_registers_from, tui_display_reg_element_at_line) (tui_display_registers_from_line, tui_check_register_values): Update. * tui/tui-data.h (union tui_which_element) <data_window>: Remove member. (struct tui_data_window) <regs_content>: Now a std::vector. <regs_content_count>: Remove. (tui_add_content_elements, tui_free_data_content): Don't declare. * tui/tui-data.c (tui_data_window::clear_detail): Update. (init_content_element): Remove DATA_WIN case. Add assert. (tui_add_content_elements): Remove. (tui_data_window): Update. (tui_free_data_content): Remove. (free_content_elements): Remove DATA_WIN case.
2019-06-25Separate out locator windowTom Tromey1-1/+1
This introduces a new subclass of tui_gen_win_info for the locator, letting us remove another element from union tui_which_element. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_refresh_all): Update. * tui/tui-win.c (tui_resize_all, tui_adjust_win_heights) (tui_source_window_base::set_new_height): Update. * tui/tui-stack.c (tui_make_status_line): Change parameter type.

(tui_locator_win_info_ptr): Change return type. (init_content_element): Remove LOCATOR_WIN case. Add assert. (tui_alloc_content): Add assert.
2019-06-25Don't check window type in tui_set_win_focus_toTom Tromey1-0/+1
This changes tui_set_win_focus_to so that it no longer checks the window type. Instead, now tui_unhighlight_win also checks whether the window can be highlighted. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_set_win_focus_to): Don't check window type. * tui/tui-wingeneral.c (tui_unhighlight_win): Check can_highlight.
2019-06-25Introduce enum tui_boxTom Tromey1-2/+3
This adds a new enum to the TUI, replacing two #define constants, providing better type safety. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_window): Change type of "box_it" parameter. * tui/tui-wingeneral.c (tui_make_window): Change type of "box_it" parameter. (tui_gen_win_info::make_visible): Update. * tui/tui-layout.c (init_and_make_win): Change type of "box_it" parameter. * tui/tui-data.h (enum tui_box): New enum. (BOX_WINDOW, DONT_BOX_WINDOW): Remove defines.
2019-06-25Move make_visible method to tui_gen_win_infoTom Tromey1-27/+14
This moves the make_visible method from tui_win_info to its base class, tui_gen_win_info. This allows the removal of another window type check. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_gen_win_info::make_visible): Rename from make_visible.

2019-06-25Introduce refresh_window methodTom Tromey1-21/+19
This replaces tui_refresh_win with a new refresh_window method. This removes another spot that was checking the window's type. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_erase_source_content) (tui_show_source_content, tui_show_exec_info_content) (tui_erase_exec_info_content): Use refresh_window method. * tui/tui-wingeneral.h (tui_refresh_win): Don't declare. * tui/tui-wingeneral.c (tui_gen_win_info::refresh_window): Rename from tui_refresh_win.

2019-06-25Derive tui_win_info from tui_gen_win_infoTom Tromey1-11/+11
This changes tui_win_info to derive from tui_gen_win_info, rather than having a tui_gen_win_info as a member. This removes a layer of member access from the entire TUI, which is why this patch is so large. This change will enable further removal of switches based on window type. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_rl_other_window, tui_enable) (tui_is_window_visible, tui_get_command_dimension): Update. * tui/tui-winsource.c (tui_update_source_window_as_is) (tui_clear_source_content, tui_erase_source_content) (tui_show_source_line, tui_source_window_base::refill) (tui_source_window_base::do_scroll_horizontal) (tui_source_window_base::set_is_exec_point_at) (tui_update_breakpoint_info, tui_set_exec_info_content) (tui_alloc_source_buffer, tui_line_is_displayed) (tui_addr_is_displayed): Update. * tui/tui-wingeneral.c (tui_unhighlight_win, tui_highlight_win) (tui_check_and_display_highlight_if_needed) (tui_win_info::make_visible, tui_win_info::refresh) (tui_refresh_all): Update. * tui/tui-windata.c (tui_first_data_item_displayed) (tui_delete_data_content_windows, tui_erase_data_content) (tui_display_all_data, tui_data_window::refresh_all) (tui_check_data_values): Update. * tui/tui-win.c (window_name_completer, tui_update_gdb_sizes) (tui_set_win_focus_to, tui_win_info::forward_scroll) (tui_win_info::backward_scroll, tui_refresh_all_win) (tui_resize_all, tui_set_focus, tui_all_windows_info) (update_tab_width, tui_set_win_height, tui_adjust_win_heights) (tui_source_window_base::set_new_height) (tui_data_window::set_new_height) (make_invisible_and_set_new_height) (make_visible_with_new_height, new_height_ok) (parse_scrolling_args): Update. * tui/tui-stack.c (tui_show_frame_info): Update. * tui/tui-source.c (tui_set_source_content) (tui_set_source_content_nil, tui_source_is_displayed) (tui_source_window::do_scroll_vertical): Update. * tui/tui-regs.c (tui_show_registers, tui_show_register_group) (tui_display_registers_from, tui_display_reg_element_at_line) (tui_check_register_values, tui_reg_command): Update. * tui/tui-layout.c (tui_default_win_height) (show_source_disasm_command, show_data, init_and_make_win) (show_source_or_disasm_and_command): Update. * tui/tui-io.c (update_cmdwin_start_line, tui_putc, tui_puts) (tui_redisplay_readline, tui_mld_flush) (tui_mld_erase_entire_line, tui_mld_getc, tui_cont_sig) (tui_getc): Update. * tui/tui-disasm.c (tui_set_disassem_content) (tui_disasm_window::do_scroll_vertical): Update. * tui/tui-data.h (struct tui_gen_win_info) <~tui_gen_win_info>: Now virtual.

2019-06-25Change tui_which_element::data_window to be a pointerTom Tromey1-1/+1
A coming patch will add a constructor to tui_gen_win_info. However, because the tui_which_element union contains an object of this type, first something must be done here in order to avoid having a union with a member that has a constructor. This patch changes this element to be a pointer instead. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_refresh_win): Update. * tui/tui-windata.c (tui_first_data_item_displayed) (tui_delete_data_content_windows): Update. * tui/tui-win.c (tui_data_window::set_new_height): Update. * tui/tui-regs.c (tui_show_registers, tui_show_register_group) (tui_display_registers_from, tui_check_register_values): Update. * tui/tui-data.h (union tui_which_element) <data_window>: Now a pointer. * tui/tui-data.c (init_content_element): Update. Allocate the new window. (tui_free_data_content): Update. (free_content_elements) <case DATA_WIN>: Free the window.
2019-06-25Introduce set_highlight methodTom Tromey1-2/+2
This introduces the tui_win_info::set_highlight method, and changes the highlighting-related code to use bool rather than int. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_unhighlight_win, tui_highlight_win): Update. * tui/tui-layout.c (make_command_window) (show_source_disasm_command, show_data, init_and_make_win) (show_source_or_disasm_and_command): Update. * tui/tui-data.h (struct tui_win_info) <set_highlight>: New method. <can_highight, is_highlighted>: Now bool. (tui_set_win_highlight): Don't declare. * tui/tui-data.c (tui_set_win_highlight): Remove.
2019-06-25Remove redundant check from make_visibleTom Tromey1-3/+1
This removes a check of the window type from make_visible. This function already checks that the window type is not CMD_WIN near the top, so this condition can never be false. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (make_visible): Remove check of window type.
2019-06-25Introduce the refresh methodTom Tromey1-11/+20
This adds tui_win_info::refresh and updates tui_source_window_base to implement it as well. This lets us simplify tui_refresh_all, removing a check of the window type. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_win_info::refresh) (tui_source_window_base::refresh): New methods. (tui_refresh_all): Call the refresh method. * tui/tui-data.h (struct tui_win_info) (struct tui_source_window_base) <refresh>: New method.
2019-06-25Use bool for visibilityTom Tromey1-11/+11
This changes the visibility-related functions and data members in the TUI to use bool rather than int. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui.h (tui_is_window_visible): Return bool. * tui/tui.c (tui_is_window_visible): Return bool. * tui/tui-wingeneral.c (tui_make_window, make_visible) (tui_make_visible, tui_make_invisible) (tui_win_info::make_visible) (tui_source_window_base::make_visible, make_all_visible) (tui_make_all_visible, tui_make_all_invisible): Update. * tui/tui-windata.c (tui_delete_data_content_windows): Update. * tui/tui-data.h (struct tui_gen_win_info) <is_visible>: Now bool. (struct tui_win_info, struct tui_source_window_base) (struct tui_cmd_window) <make_visible>: Change parameter to bool. * tui/tui-data.c (tui_init_generic_part): Update.
2019-06-25Introduce make_visible methodTom Tromey1-11/+18
This introduceds the make_visible to tui_win_info and overrides it in subclasses as appropriate. This allows the removal of the tui_win_is_source_type, as it is no longer used. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_win_info::make_visible) (tui_source_window_base::make_visible): New methods.

2019-06-25Remove struct tui_source_infoTom Tromey1-4/+9
The tui_source_info struct is used as a member of the "detail" union in tui_win_info, and this member of the union is only used by source and disassembly windows. This patch removes tui_source_info and moves its members directly to tui_source_window_base. This simplifies the code by removing a layer of references from many places. In a few spots, a new cast was needed, but most of these will be removed by the end of the series. gdb/ChangeLog 2019-06-25 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_window) (tui_refill_source_window) (tui_source_window_base::do_scroll_horizontal) (tui_update_breakpoint_info, tui_set_exec_info_content) (tui_show_exec_info_content, tui_erase_exec_info_content) (tui_clear_exec_info_content): Update. * tui/tui-wingeneral.c (make_all_visible, tui_refresh_all): Update. * tui/tui-win.c (make_invisible_and_set_new_height) (make_visible_with_new_height): Update. * tui/tui-source.c (tui_set_source_content) (tui_show_symtab_source): Update. * tui/tui-layout.c (extract_display_start_addr) (show_source_disasm_command, show_data) (make_source_or_disasm_window) (show_source_or_disasm_and_command): Update. * tui/tui-disasm.c (tui_set_disassem_content): Simplify.

2019-06-16Don't cast a tui_win_info directly to tui_gen_win_infoTom Tromey1-3/+3
I found a few spots that directly cast a tui_win_info to a tui_gen_win_info. However, I think it's a bit better here to take the address of the "generic" member. As far as I know, nothing relies on being able to downcast here, so this gives us the freedom to rearrange the structure. gdb/ChangeLog 2019-06-16 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_unhighlight_win, tui_highlight_win) (make_all_visible): Use address of member.
2019-06-16Remove unnecessary casts of NULLTom Tromey1-7/+7
I noticed some unnecessary casts of NULL. This removes all the unnecessary ones, leaving only ones where we must ensure that NULL has pointer type for passing through varargs.
