From fecfeff6c34c1ac11c4803cb3ffc0b6722bd93b7 Mon Sep 17 00:00:00 2001 From: raveit65 Date: Sun, 26 Jun 2016 20:45:02 +0200 Subject: Gtk+-3.20 eel-canvas: use GdkSeat operations Some GdkDisplay operations have been deprecated in GDK 3.20. This commit replaces the deprecated code in eel_canvas_item_grab() and eel_canvas_item_ungrab() functions with new GdkSeat operations. https://bugzilla.gnome.org/show_bug.cgi?id=762235 taken from: https://git.gnome.org/browse/nautilus/commit/?id=225f2cf --- eel/eel-canvas.c | 113 ++++++++++++++++++++++++++++++++++++++++++++++++++++--- eel/eel-canvas.h | 18 +++++++++ 2 files changed, 125 insertions(+), 6 deletions(-) (limited to 'eel') diff --git a/eel/eel-canvas.c b/eel/eel-canvas.c index 1e45224d..ae4faaa7 100644 --- a/eel/eel-canvas.c +++ b/eel/eel-canvas.c @@ -342,7 +342,11 @@ eel_canvas_item_dispose (GObject *object) } #if GTK_CHECK_VERSION(3, 0, 0) +#if GTK_CHECK_VERSION(3, 20, 0) + eel_canvas_item_ungrab (item); +#else eel_canvas_item_ungrab (item, GDK_CURRENT_TIME); +#endif #else if (item == item->canvas->grabbed_item) { @@ -873,7 +877,35 @@ eel_canvas_item_hide (EelCanvasItem *item) } } +#if GTK_CHECK_VERSION(3, 20, 0) +/* + * Prepare the window for grabbing, i.e. show it. + */ +static void +seat_grab_prepare_window (GdkSeat *seat, + GdkWindow *window, + gpointer user_data) +{ + gdk_window_show (window); +} +/** + * eel_canvas_item_grab: + * @item: A canvas item. + * @event_mask: Mask of events that will be sent to this item. + * @cursor: If non-NULL, the cursor that will be used while the grab is active. + * @event: The event, triggering the grab, if any. + * + * Specifies that all events that match the specified event mask should be sent + * to the specified item, and also grabs the seat by calling gdk_seat_grab(). + * If @cursor is not NULL, then that cursor is used while the grab is active. + * + * Return value: If an item was already grabbed, it returns %GDK_GRAB_ALREADY_GRABBED.
