gtk apps set an atom which provides information about the area
where non-window content (eg. shadows) may be drawn; this area
must not be used in placement calculations.
the easiest method for implementing this functionality was to add
a case to the compositor geometry interceptors which effectively
flip the client struct geometry values such that the E_Client->client
is outside of the more commonly used E_Client->x/y/w/h
fix T2744
failure to allow pixmaps/clients to be retrived by parent window will
result in api users being greatly inconvenienced after a reparenting has
occurred
it seems that since the first version of the enlightenment compositor
in e17, damage events in x11 have never been used correctly. using
the event struct members will only give the bounding box/area instead
of the damaged regions; the real regions must be explicitly fetched
from the server
this removes the need for a lot of hacks which were added over the years
to make override windows render correctly, and also probably reduces
rendering overhead slightly
in the case that the canvas window has just had focus set on it, apply this focus
and ensure that no client retains focus
this resolves a race condition where focusing the compositor canvas <-> client
extremely quickly would result in a client trying to steal focus when it was
not actually focused
a notable (but trivial) side effect is that now when flipping desks at high speed while using
mouse-based focus policies, the user is almost guaranteed to end on a desk which
has open windows on it
it seems that the reported damage events upon resizing an override window
are not accurate, and so we must force a full damage here while avoiding a
render queue in order to ensure that the full contents of the override will
be rendered in the next frame
fix T2045
these are triggered "in passing" when mouse in events occur and do
not necessarily indicate that the mouse has entered this specific window
failing to reject such events can cause mouse-based focus policies to
attempt to set focus onto windows which are not visible, resulting in
an infinite loop where no window is actually focused
in the event that these windows are different, event_window is the parent of window
which may or may not be explicitly tracked by an E_Client, so the wheel events here
should be sent to the parent as is done in mouse button events
fix T2604
it seems that some clients, eg. libreoffice, don't set the modal window
property on child dialogs. instead of fighting for focus, set up the child
as a modal on the parent and then avoid the whole issue
fix T2594
a client with this flag set here is unreliable to use as a stacking
reference since it has yet to be stacked and can be located anywhere
in the window stack.
fixes internal window stacking on startup
blocks execution of resizes until the surface commit arrives. reduces
the race condition between resize and render and eliminates frame drops
during slow resizes
xwayland compositing requires that we set up a root window cursor image
immediately since we'll be getting that cursor surface to display as soon
as the pointer goes out of an x11 client's window
this requires that both canvas cursors and window cursors be present for the same
E_Pointer object, even though only the canvas cursor is actually visible
#kansas
due to recent changes in ecore-input-evas, mouse events are propagated
differently; specifically, there are now "more" events than there previously were.
as a result, grabs on internal wins are no longer necessary, though they probably
never were necessary after the elm conversion
