Move to screen

[tobiasBora]

I often want to move some/all windows to a given screen, and I'd love to write some scripts to do that, but as far as I see kdotool does not provide tools to change screen directly. It is possible to change the position, which indirectly moves it to a different screen, but knowing the position of the screen may require additional non-trivial commands.

This. We need a way to easily move a window to a specific screen. Doing arithmetics to calculate the correct x and y position for a window to go to another screen is certainly a pain in the ass :(

Since kwin has a "move window to screen #" hotkey, I'll check how it's implemented (especially what to do when the window would be out of the target screen, e.g. when a window is in the bottom-right corner, and we move it to a smaller screen).

@jinliu I didn't look at the code, but by observing the behaviour, it seems like it tries to preserve the relative position in the source screen when moving it, but clamping the maximum x and y to not end up outside the destination screen. In the case of source dimensions > destination dimensions, that is.

Otherwise, the window ends up in the "same position" it was but as if the source screen (smaller) was on top of the destination screen (bigger), centered horizontally and vertically. Interesting.
