swap_and_focus* commands

[dalyIsaac]

Current behavior is to swap window position, but keep the current window focused.

• swap_and_focus_window.left
• swap_and_focus_window.right
• swap_and_focus_window.up
• swap_and_focus_window.down
• move_and_focus_window.next_monitor
• move_and_focus_window.previous_monitor

I had look into this and I can offer a bit more information.

Clarification

In most cases, the current default behavior of the various swap_window* commands is already doing what this feature request is asking: The focus follows then moved window.

Exception

The one case I could find where this is not true, is when focus-follows-mouse is enabled in the OS settings. Apologies that I didn't catch this earlier (I am so used to this setting, that I didn't think about that this may be the culprit). So instead of a feature request, this should have been a bug report.

Fix

In the simplest case, this can be fixed by actively focusing the moved window with window.Focus() after it has been moved. However, this fails when the move triggers any resizing among other windows (e.g., on the old monitor after move_window_to_monitor). In this case, the resizing may move another window underneath the mouse cursor, snatching the focus away again.

I played around a bit, and one somewhat hacky fix is to delay the window.Focus() by a few hundred milliseconds:

Task.Run(async delegate
{
    await Task.Delay(300);
    window.Focus();
});

This seems to do the trick based on my initial testing but it definitely feels hacky. A cleaner solution might be to also move the mouse pointer to the center of the moved window.
