This issue looks like it would be better suited to the devel list and
perhaps the bug tracker.

Since nobody seems to care, I took some investigation and found out the
following:
If I patch inkscape in order to produce output in
sp_select_context_root_handler and sp_select_context_item_handler and
put a printf at case GDK_BUTTON_PRESS, GDK_ENTER_NOTIFY,
GDK_LEAVE_NOTIFY on select_context_item_handler as well as
GDK_BUTTON_PRESS and GDK_BUTTON_RELEASE at select_context_root (the
latter two I'll be naming GDK_BUTTON_PRESS/RELEASE____root from now on,
I get the following behavior:
if I draw a square with the rectangle tool and switch to select (F1), I
can move the mouse over the rectangle and I get GDK_ENTER_NOTIFY
If I move the mouse out of the rectangle, I get GDK_LEAVE_NOTIFY
If I press somewhere (outside of the rectanlge), I get
GDK_BUTTON_PRESS____root, and when I release, I get
GDK_BUTTON_RELEASE____root. This is also valid for the tablet.
If I press somewhere *in* the rectangle, with the mouse I get
GDK_LEAVE_NOTIFY
GDK_ENTER_NOTIFY
GDK_BUTTON_PRESS
and if I release, I get
GDK_BUTTON_RELEASE___root
GDK_BUTTON_RELEASE___root (that's right, I get it twice),
and the rectangle is selected.
If I do the same with the tablet, I get
GDK_LEAVE_NOTIFY
GDK_BUTTON_PRESS____root
and upon release
GDK_BUTTON_RELEASE____root
GDK_ENTER_NOTIFY
and nothing is selected at all.
Maybe someone with a bit more insight could help me out here. It might
have to do something with GDK and/or its implementation of XInput, but
this would not explain the different behavior, I mean pressing outside
of the rectangle generates PRESS and RELEASE as expected, but if there's
an object under it, why is there a leave notify *not* followed by a
enter notify just as it is the case with the mouse?
Cheers,
Alex
