From 458c0b95257ec00791cdda4a2d04f64bafbb6e63 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Florian=20M=C3=BCllner?= Date: Sat, 21 May 2016 00:07:10 +0200 Subject: stack: Only map children when necessary gtk_widget_set_parent() will map the widget if the parent is mapped and the widget is both visible and child-visible. As we currently only set the child visibility after adding the child, we immediately map all children that are added to a mapped stack, even when they are not actually shown. Avoid this by setting the child visibility before adding the child, so widgets are only mapped when shown. https://bugzilla.gnome.org/show_bug.cgi?id=766737 --- gtk/gtkstack.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/gtk/gtkstack.c b/gtk/gtkstack.c index b691b65b68..13ae25d236 100644 --- a/gtk/gtkstack.c +++ b/gtk/gtkstack.c @@ -1283,6 +1283,7 @@ gtk_stack_add (GtkContainer *container, priv->children = g_list_append (priv->children, child_info); + gtk_widget_set_child_visible (child, FALSE); gtk_widget_set_parent_window (child, priv->bin_window); gtk_widget_set_parent (child, GTK_WIDGET (stack)); @@ -1299,8 +1300,6 @@ gtk_stack_add (GtkContainer *container, if (priv->visible_child == NULL && gtk_widget_get_visible (child)) set_visible_child (stack, child_info, priv->transition_type, priv->transition_duration); - else - gtk_widget_set_child_visible (child, FALSE); if (priv->hhomogeneous || priv->vhomogeneous || priv->visible_child == child_info) gtk_widget_queue_resize (GTK_WIDGET (stack)); -- cgit v1.2.1
