2019-03-11curses: support wide inputSamuel Thibault1-14/+62
This makes use of wide curses functions instead of 8bit functions. This allows to type e.g. accented letters. Unfortunately, key codes are then returned with values that could be confused with wide characters by ncurses, so we need to add a maybe_keycode variable to know whether the returned value is a key code or a character (curses with wide support), or possibly both (curses without wide support). The translation tables thus also need to be separated into key code translation and character translation. The curses2foo helper makes it easier to use them.

2019-03-11Reduce curses escdelay from 1s to 25msSamuel Thibault1-1/+2
By default, curses will only report single ESC key event after 1s delay, since ESC is also used for keypad escape sequences. This however makes users believe that ESC is not working. Reducing to 25ms provides good user experience, while still allowing 25ms for keypad sequences to get in, which should be enough.

2019-02-05keymap: fix keyup mappingsGerd Hoffmann1-1/+1
It is possible that the modifier state on keyup is different from the modifier state on keydown. In that case the keycode lookup can end up with different keys in case multiple keysym -> keycode mappings exist, because it picks the mapping depending on modifier state. To fix that change the lookup logic for keyup events. Instead of looking at the modifier state check the key state and prefer a keycodes where the key is in "down" state right now.

2017-01-10curses: Fix compiler warnings (Mingw-w64 redefinition of macro KEY_EVENT)Stefan Weil1-1/+0
For builds with Mingw-w64 as it is included in Cygwin, there are two header files which define KEY_EVENT with different values. This results in lots of compiler warnings like this one: CC vl.o In file included from /qemu/include/ui/console.h:340:0, from /qemu/vl.c:76: /usr/i686-w64-mingw32/sys-root/mingw/include/curses.h:1522:0: warning: "KEY_EVENT" redefined #define KEY_EVENT 0633 /* We were interrupted by an event */ In file included from /usr/share/mingw-w64/include/windows.h:74:0, from /usr/share/mingw-w64/include/winsock2.h:23, from /qemu/include/sysemu/os-win32.h:29, from /qemu/include/qemu/osdep.h:100, from /qemu/vl.c:24: /usr/share/mingw-w64/include/wincon.h:101:0: note: this is the location of the previous definition #define KEY_EVENT 0x1 QEMU only uses the KEY_EVENT macro from wincon.h. Therefore we can undefine the macro coming from curses.h. The explicit include statement for curses.h in ui/curses.c is not needed and was removed. Those two modifications fix the redefinition warnings.

2016-09-13ui/curses.c: Clean up nextchr logicPeter Maydell1-11/+4
Coverity identifies that at the top of the while(1) loop in curses_refresh() the variable nextchr is always ERR, and so the else case of the first if() is dead code. Remove this dead code, and narrow the scope of the nextchr variable to the place where it's used. (This confused logic has been present since the curses code was added to QEMU in 2008.)

2016-01-08ui/curses: Fix color attribute of monitor for cursesOGAWA Hirofumi1-3/+10
Current text_console_update() writes totally broken color attributes to console_write_ch(). The format now is writing, [WRONG] bold << 21 | fg << 12 | bg << 8 | char fg == 3bits curses color number bg == 3bits curses color number I can't see this format is where come from. Anyway, this doesn't work at all. What curses expects is actually (and vga.c is using), [RIGHT] bold << 21 | bg << 11 | fg << 8 | char fg == 3bits vga color number bg == 3bits vga color number And curses set COLOR_PAIR() up to match this format, and curses's chtype. I.e, bold | color_pair | char color_pair == (bg << 3 | fg) To fix, this simply uses VGA color number everywhere except curses.c internal. Then, convert it to above [RIGHT] format to write by console_write_ch(). And as bonus, this reduces to expose curses define to other parts (removes COLOR_* from console.c).

2015-11-06ui: Use g_new() & friends where that makes obvious senseMarkus Armbruster1-1/+1
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2015-11-03ui/curses: Fix monitor color with -curses when 256 colorsOGAWA Hirofumi1-1/+6
If TERM=xterm-256color, COLOR_PAIRS==256 and monitor passes chtype like 0x74xx. Then, the code uses uninitialized color pair. As result, monitor uses black for both of fg and bg color, i.e. terminal is filled by black. To fix, this initialize above than 64 with default color (fg=white,bg=black).
