From 2d83e710a14c62cb6a9501c84fc46062f817428d Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 11 Jul 2019 18:03:45 -0600 Subject: Remove separate visibility flag 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 * 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) : New method. : Remove field. * tui/tui-data.c (tui_next_win, tui_prev_win) (tui_delete_invisible_windows): Update. --- gdb/tui/tui-data.c | 6 +++--- gdb/tui/tui-data.h | 8 ++++++-- gdb/tui/tui-disasm.c | 2 +- gdb/tui/tui-regs.c | 9 ++++----- gdb/tui/tui-source.c | 2 +- gdb/tui/tui-win.c | 14 +++++++------- gdb/tui/tui-wingeneral.c | 8 +++----- gdb/tui/tui.c | 2 +- 8 files changed, 26 insertions(+), 25 deletions(-) (limited to 'gdb/tui') diff --git a/gdb/tui/tui-data.c b/gdb/tui/tui-data.c index dc2c810..9b80aca 100644 --- a/gdb/tui/tui-data.c +++ b/gdb/tui/tui-data.c @@ -148,7 +148,7 @@ tui_next_win (struct tui_win_info *cur_win) while (type != cur_win->type && (next_win == NULL)) { if (tui_win_list[type] - && tui_win_list[type]->is_visible) + && tui_win_list[type]->is_visible ()) next_win = tui_win_list[type]; else { @@ -178,7 +178,7 @@ tui_prev_win (struct tui_win_info *cur_win) while (type != cur_win->type && (prev == NULL)) { if (tui_win_list[type] - && tui_win_list[type]->is_visible) + && tui_win_list[type]->is_visible ()) prev = tui_win_list[type]; else { @@ -220,7 +220,7 @@ tui_delete_invisible_windows () for (int win_type = SRC_WIN; (win_type < MAX_MAJOR_WINDOWS); win_type++) { if (tui_win_list[win_type] != NULL - && !tui_win_list[win_type]->is_visible) + && !tui_win_list[win_type]->is_visible ()) { /* This should always be made visible before a call to this function. */ diff --git a/gdb/tui/tui-data.h b/gdb/tui/tui-data.h index 6c7ab05..7993c63 100644 --- a/gdb/tui/tui-data.h +++ b/gdb/tui/tui-data.h @@ -79,6 +79,12 @@ public: return false; } + /* Return true if this window is visible. */ + bool is_visible () const + { + return handle != nullptr; + } + /* Window handle. */ WINDOW *handle = nullptr; /* Type of window. */ @@ -91,8 +97,6 @@ public: struct tui_point origin = {0, 0}; /* Viewport height. */ int viewport_height = 0; - /* Whether the window is visible or not. */ - bool is_visible = false; /* Window title to display. */ char *title = nullptr; }; diff --git a/gdb/tui/tui-disasm.c b/gdb/tui/tui-disasm.c index 2394394..3ebe303 100644 --- a/gdb/tui/tui-disasm.c +++ b/gdb/tui/tui-disasm.c @@ -253,7 +253,7 @@ tui_show_disassem (struct gdbarch *gdbarch, CORE_ADDR start_addr) struct tui_win_info *win_with_focus = tui_win_with_focus (); struct tui_line_or_address val; - gdb_assert (TUI_DISASM_WIN != nullptr && TUI_DISASM_WIN->is_visible); + gdb_assert (TUI_DISASM_WIN != nullptr && TUI_DISASM_WIN->is_visible ()); val.loa = LOA_ADDRESS; val.u.addr = start_addr; diff --git a/gdb/tui/tui-regs.c b/gdb/tui/tui-regs.c index 89faefa..36973ff 100644 --- a/gdb/tui/tui-regs.c +++ b/gdb/tui/tui-regs.c @@ -138,7 +138,7 @@ tui_show_registers (struct reggroup *group) /* Make sure the register window is visible.
