Feature request: Drag viewport to move window (Xorg) about mpc-qt HOT 7 CLOSED

In my desktop environment, video players MPV, SMPlayer, and VLC can all move the window by starting a click and drag on the video viewport, even while the left mouse button is also bound to the play/pause action. This is especially useful when all GUI elements are hidden except the viewport.

Sure.

I also have no idea whether this is possible with Wayland. I don't use Wayland because I've heard it has limitations with software which positions and sizes its own windows, and has no user-facing advantages if your desktop already renders without frame drops and tearing under Xorg, which mine does.

We explicitly force XCB instead of wayland because wayland's window management is broken by design, and sane window management is more important for me than any """"benefit"""" that wayland brings. I believe you can blame some of the sway devs for this situation. Wayland breaks these three settings:



Until that is fixed, I couldn't care less about wayland.

Yes, of course it would be a benefit for Windows users for a Windows-specific implementation of this feature to also be implemented for Windows, but that's not part of this particular feature request.

I think this is possible, although I don't think Qt has an API for voluntarily entering a window drag on wayland. Or any platform for that matter. For Wayland, I'd need to access the underlying platform and do it raw, which isn't what one would call good code. For other platforms it can be done à la wheel-reinventing with cursor tracking + window move events, the usual way. I could simply not do this on wayland.

Re: the other apps you mentioned.

Smplayer forces use of xcb and will fail to run if DISPLAY is not set. So it can always fake a window move whenever it wants.

As for vlc, unsetting DISPLAY and forcing the fusion style with QT_STYLE_OVERRIDE=fusion does not allow the window to be dragged by the viewport. On Linux, it's a feature of the Breeze theme to enter window drag from window areas, not vlc. I haven't tested vlc on Windows to see if it does that there too.

mpv talks wayland natively and can enter a window drag from the viewport.

So that's the state of this. A platform-specific code path is needed for wayland, and faking a window move for everyone else.

Just to clarify here, I also don't use Wayland and this feature request is not requesting implementation with or in Wayland. I agree with you.

If implemented, I presume this would also work on Windows?

The title specifies "Xorg", so if the feature request was fulfilled as written, it would not.

Click to drag is also available on the Windows versions of the players that you mentioned, as a note
