* SECTION:gtktoolbutton
* @Short_description: A GtkToolItem subclass that displays buttons
* @Title: GtkToolButton
* @See_also: #GtkToolbar, #GtkMenuToolButton, #GtkToggleToolButton,
* #GtkRadioToolButton, #GtkSeparatorToolItem
*
* #GtkToolButtons are #GtkToolItems containing buttons.
*
* Use gtk_tool_button_new() to create a new #GtkToolButton.
*
* The label of a #GtkToolButton is determined by the properties
* #GtkToolButton:label-widget and #GtkToolButton:label.
* If #GtkToolButton:label-widget is
* non-%NULL, then that widget is used as the label. Otherwise, if
* #GtkToolButton:label is non-%NULL, that string is used as the label.
*
* The icon of a #GtkToolButton is determined by the
* #GtkToolButton:icon-widget property. If
* #GtkToolButton:icon-widget is non-%NULL, then
* that widget is used as the icon. Otherwise it does not have an icon.
*
* # CSS nodes
*
* GtkToolButton has a single CSS node with name toolbutton.
