* SECTION:gtkframe
|
||
* @Short_description: A bin with a decorative frame and optional label
|
||
* @Title: GtkFrame
|
||
*
|
||
* The frame widget is a Bin that surrounds its child
|
||
* with a decorative frame and an optional label.
|
||
* If present, the label is drawn in a gap in the
|
||
* top side of the frame. The position of the
|
||
* label can be controlled with gtk_frame_set_label_align().
|
||
*
|
||
* # 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="GtkFrame">
|
||
* <child type="label">
|
||
* <object class="GtkLabel" id="frame-label"/>
|
||
* </child>
|
||
* <child>
|
||
* <object class="GtkEntry" id="frame-content"/>
|
||
* </child>
|
||
* </object>

||
* ]|
