#include "gtkwidget.h"
a11y: Don't include gtk.h Also add missing includes and sort them for all the widgets that relied on that before.

Keep more event controller api private We don't want to expose the GtkCrossingData struct, and manually feeding events to event controllers is not something we want to encourage, going forward.
2020-02-20 22:22:03 +00:00
#include "gtkeventcontrollerprivate.h"
widget: Add gtk_widget_observe_children() This creates a listmodel that tracks a widget's children. Doing so turns adding/removing children from O(1) to O(N) though, so use with caution.

#include "gtksizerequestcacheprivate.h"
widget: Add static inline version of gtk_widget_display() Due to the few type checks in gtk_widget_get_display(), it was the slowest part of a call to gtk_widget_query_size_for_orientation if the in case of a cache hit.
2018-04-21 15:03:31 +00:00
#include "gtkwindowprivate.h"
widget: Remove controller sequence-state-changed signal connection We can avoid a signal connection per event controller (and the EventControllerData struct) since every event controller knows the widget it's attached to.

widget: Add surface relative transform changed callback Added two new private GtkWidget API: * gtk_widget_add_surface_transform_changed_callback() * gtk_widget_remove_surface_transform_changed_callback() The intention is to let the user know when a widget transform relative to the surface changes. It works by calculating the surface relative transform during allocation, and notifying the callbacks if it changed since last time. Each widget adds itself as a listener to its parent widget, thus will be triggered if a parents surface relative transform changes.

GtkWidget: Add gtk_widget_insert_action_group() This allows adding a GActionGroup with a given name at an arbitrary point in the widget tree. This patch also adds an internal _get_action_muxer() API. Calling this will create a GActionMuxer associated with the widget. The parent of the muxer will be the muxer of the widget's conceptual parent. For non-menus, that is the normal parent. For menus, it is the attach widget. In this way, we end up with a hierarchy of GActionMuxer that largely reflects the hierarchy of GtkWidget, but only in places that the action context has been requested. These muxers are the ones on which the inserted actions groups are installed. A following patch will add a user of this API.
