Package: xwit
Version: 3.4-16+b1
Severity: wishlist
Dear Maintainer,
xwit should support the Multi Pointer X system that comes with the
current Xorg server. It should have options to run
- XISetClientPointer because window managers
don't bother to run it.
- XISetFocus for the same reason.
- XIWarpPointer in addition to XWarpPointer
Having these options in xwit will enable users to do many multi pointer
things that otherwise would require patching many applications.
It enables running multiple programs or program instances simultaneously
that each want to grab the pointer or have some unwanted effect when
losing focus.
Examples:
Running multiple instances of minetest on same Xorg server is normally
not possible, because each instance will want to grab the pointer. After
running XISetClientPointer on them, each instance will grab only the
designated pointer and all instances can be used simultanously.
Running koules with a gamepad while doing something else with a mouse
and keyboard is normally not possible, because koules will pause when
losing focus. Running XISetClientPointer and XISetFocus can prevent
it form losing focus.
I wrote a patch to add these options to xwit.
