public class Frame : Widget, Accessible, Buildable, ConstraintTarget
The frame widget is a widget that surrounds its child with a decorative frame and an optional label.
If present, the label is drawn inside the top edge of the frame. The horizontal position of the label can be controlled with set_label_align.
GtkFrame clips its child. You can use this to add rounded corners to widgets, but be aware that it also cuts off shadows.
GtkFrame as GtkBuildable
The GtkFrame implementation of the GtkBuildable interface supports placing a child in the label position by specifying “label” as the “type” attribute of a <child> element. A normal content child can be specified without specifying a <child> type attribute.
An example of a UI definition fragment with GtkFrame:
<object class="GtkLabel" id="frame_label"/>
<object class="GtkEntry" id="frame_content"/>
as a main CSS node with name “frame”, which is used to draw the visible border. You can set the appearance of the border using CSS properties like “border-style” on this node.
