# We need to track certain mouse events in order to close the palette

# when the mouse leaves the palette and the invoker widget, but
|
|
# GtkMenu makes our lives hard here.
|
|
#
|
|
# GtkMenu takes a grab on the root window, meaning that normal
|
|
# enter/leave events are not sent to the relevant widgets.
|
|
# However, connecting enter-notify and leave-notify events in this
|
|
# GtkMenu subclass mean that we get to see the events being grabbed.
|
|
# With certain filtering in place (see _enter_notify_cb and
|
|
# _leave_notify_cb) we are able to accurately determine when the
|
|
# mouse leaves/enters the palette menu. Some spurious events are
|
|
# generated but the important thing is that the last event generated
|
|
# in response to a user action is always reliable (i.e. we will
|
|
# always get a leave event last if the user left the menu,
|
|
# even if we get some strange enter events leading up to it).
|
|
#
|
|
# This is complicated with submenus; in this case the submenu takes
|
|
# the grab, so we must also listen for events on any submenus of
|
|
# the palette and apply the same considerations.
|
|
#
|
|
# The remaining challenge is tracking when the mouse enters or leaves
|
|
# the invoker area. While the appropriate GtkMenu grab is active,
|
|
# we do get informed of such events, however these events will only
|
|
# arrive if the user has entered the menu. If the user hovers over
|
|
# the invoker and then leaves the invoker without entering the palette,
|
|
# we get no enter/leave event.
|
|
# We work around this by tracking mouse motion events. When the mouse
|
|
# moves, we compare the mouse coordinates to the region occupied by the
|
|
# invoker, and this lets us track enter/leave for the invoker widget.
