[PATCH 1/2] ui/gtk: enable fullscreen hotkey for detached windows

[PATCH 1/2] ui/gtk: enable fullscreen hotkey for detached windows

[dongwon.kim]

From: Dongwon Kim <dongwon.kim@intel.com>

Currently, the fullscreen toggle hotkey (Ctrl+Alt+f by default) only
functions for the main QEMU window. When a Virtual Console (VC) is
detached into its own separate window (untabified), it loses this
capability.

Implement a toggle helper, gd_win_fullscreen, and connect it to
the 'f' accelerator when a detached window is created in
gd_menu_untabify. This allows individual detached windows to be
toggled fullscreen independently.

[PATCH 2/2] ui/gtk: register "Grab Input" shortcut to accel_group

[dongwon.kim]

From: Dongwon Kim <dongwon.kim@intel.com>

The "Grab Input" shortcut key currently fails to trigger when the
window is in fullscreen mode because the menubar is hidden, which
disables GtkAccelMap-based shortcuts associated with it.

To ensure the accelerator remains active in fullscreen, connect it
directly to s->accel_group and explicitly set the hotkey display on
the menu item label.

gd_menu_full_screen restores it to gfx.preferred_scale

For consistency with gd_menu_full_screen() it should call gd_update_cursor

You also hook grab, this should be mentionned in the commit message.

btw, it would be nice to remove the stderr printf there..

Why not add the zoom keys while at it?

thanks

https://docs.gtk.org/gtk3/method.AccelGroup.connect.html
The signature used for the closure is that of GtkAccelGroupActivate.

This means that other key events could potentially be triggered. It
should return true (handled).

I will change this. This was based on what was done in menu_full_screen a while ago.
I didn't notice it was changed there. In addition to that, I will take out check on free_scale
as well.

Yes, I will remove it.

Yes, we can enable other hotkeys. I am going to add zoom in/out/reset keys.
I think it's better to create a new commit with all these major changes included
rather than going with v2.
