Prevent Emacs frames from restacking themselves
Putting Emacs frames (workspace frames, floating frames) into dedicated containers greatly simplifies the stacking order management and totally fixes relevant issues. * exwm-floating.el (exwm-floating--set-floating): Create floating frame container. Remove redundant stacking order modification code. (exwm-floating--unset-floating): Destroy the floating frame container. No need to reparent the X window container. (exwm-floating--do-moveresize): Resize the floating frame container. * exwm-input.el (exwm-input--update-focus): No need to restack frames. * exwm-layout.el (exwm-layout--show, exwm-layout--set-frame-fullscreen) (exwm-layout-enlarge-window): Resize the floating frame container. * exwm-manage.el (exwm-manage--on-ConfigureRequest): Re-enable stacking order modification on ConfigureRequest. * exwm-workspace.el (exwm-workspace--confirm-kill-emacs): Reparent out all frames on exit. No need to remove selected events or created resources. (exwm-workspace--init): Create workspace frame containers. * exwm-layout.el (exwm-layout-set-fullscreen): * exwm-manage.el (exwm-manage--unmanage-window): Remove a redundant call to `xcb:flush'. * exwm-manage.el (exwm-manage--unmanage-window): Force unmap the X window. Unmap the floating frame before reparent it.
