A #GtkExpander allows the user to hide or show its child by clicking
|
|
on an expander triangle similar to the triangles used in a #GtkTreeView.

Normally you use an expander as you would use any other descendant
|
|
of #GtkBin; you create the child widget and use gtk_container_add()
|
|
to add it to the expander. When the expander is toggled, it will take
|
|
care of showing and hiding the child automatically.

There are situations in which you may prefer to show and hide the
|
|
expanded widget yourself, such as when you want to actually create
|
|
the widget at expansion time. In this case, create a #GtkExpander
|
|
but do not add a child to it. The expander widget has an
|
|
<literal>expanded</literal> property which can be used to monitor
|
|
its expansion state. You should watch this property with a signal
|
|
connection as follows:

<para>
|
|
The GtkExpander 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.
