Reimplement Palettes for GTK3
Moving from GTK2 to GTK3 has presented various challenges regarding palettes. In GTK2, we were able to access some internal API of the GtkMenu class and use it to embed a GtkMenu in a regular window. As of GTK3, that API has become private and we can no longer access it. We still want to use GtkMenu for the advanced functionality it provides (multiple-level menus, keyboard navigation, etc), but we are now limited to popping it up with its own (internal) window, rather than being able to pack it into one of our own. Our palettes can historically be used either as a menu, or as a general area where widgets can be added, or both. The new restrictions upon GtkMenu force some changes here, but we work hard to stick to the old API as far as possible. A Palette instance now acts as a controller of either a "window widget" (where any type of widget can be displayed as usual) or a "menu widget" which just pops up a GtkMenu. A Palette defaults to the window mode, but dynamically switches to menu mode if/when the user attempts to access the menu element. As a result of this, palettes can now pack either a user-defined collection of widgets, or a menu, but types can no longer be mixed. This should only affect a handful of palettes which will need to pick a single approach and convert to it. Some further challenges are presented by the fact that GtkMenu performs a grab on the whole screen, meaning that all input events are delivered to the GtkMenu widget. Through some careful event filtering and examination of the mouse cursor position we are still able to determine when the mouse has entered or left the invoker or menu areas. This work is authored by Benjamin Berg, Marco Pesenti Gritti, Simon Schampijer and Daniel Drake.

# 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.
