From edbe25f38a2d5867dec066288cb61adf6191f327 Mon Sep 17 00:00:00 2001 From: pavelxdd Date: Fri, 22 Dec 2017 19:19:28 +0300 Subject: w32_common: use the screen working area when resizing the window This makes the default fit on screen, autofit and window-scale changing behavior to use the screen working area, instead of the whole screen area. As a result mpv window doesn't cover the taskbar now when opening videos with size larger than the screen size. The actual behavior now is the same as expected behavior for usecases 1-4 from #4363. This commit also removes the screenrc from w32 struct. The screen rect can now be retrieved via `get_screen_area` function, which was renamed from `update_screen_rect`. On a multi-monitor system, if the user moved the window between monitors, this function will return the current screen area under the window, and not the screen area from monitor specified by `--screen` option. The `--screen` option sets the initial monitor the mpv window is displayed on. --- video/out/w32_common.c | 155 ++++++++++++++++++++++++++----------------------- 1 file changed, 81 insertions(+), 74 deletions(-) diff --git a/video/out/w32_common.c b/video/out/w32_common.c index de81b35dca..92b6650c09 100644 --- a/video/out/w32_common.c +++ b/video/out/w32_common.c @@ -101,9 +101,7 @@ struct vo_w32_state { bool toggle_fs; // whether the current fullscreen state needs to be switched RECT windowrc; // currently known window rect - RECT screenrc; // current screen rect - // last non-fullscreen rect, updated only on fullscreen or on initialization - RECT prev_windowrc; + RECT prev_windowrc; // last non-fullscreen window rect // video size uint32_t o_dwidth; @@ -606,6 +604,80 @@ static void update_playback_state(struct vo_w32_state *w32) TBPF_NORMAL); } +struct get_monitor_data { + int i; + int target; + HMONITOR mon; +}; + +static BOOL CALLBACK get_monitor_proc(HMONITOR mon, HDC dc, LPRECT r, LPARAM p) +{ + struct get_monitor_data *data = (struct get_monitor_data*)p; + + if (data->i == data->target) { + data->mon = mon; + return FALSE; + } + data->i++; + return TRUE; +} + +static HMONITOR get_monitor(int id) +{ + struct get_monitor_data data = { .target = id }; + EnumDisplayMonitors(NULL, NULL, get_monitor_proc, (LPARAM)&data); + return data.mon; +} + +static HMONITOR get_default_monitor(struct vo_w32_state *w32) +{ + const int id = w32->current_fs ?
