Class: Gtk::AspectFrame
- Defined in:
- (unknown)
Overview
GtkAspectFrame preserves the aspect ratio of its child.
The frame can respect the aspect ratio of the child widget, or use its own aspect ratio.
CSS nodes
GtkAspectFrame uses a CSS node with name frame.
Accessibility
Until GTK 4.10, GtkAspectFrame used the GTK_ACCESSIBLE_ROLE_GROUP role.
Starting from GTK 4.12, GtkAspectFrame uses the GTK_ACCESSIBLE_ROLE_GENERIC role.
