* Use gtk_tool_button_new() to create a new #GtkToolButton.
*
* The label of a #GtkToolButton is determined by the properties
* #GtkToolButton:label-widget, #GtkToolButton:label, and
* #GtkToolButton:stock-id. 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.
* Otherwise, if #GtkToolButton:stock-id is non-%NULL, the label is
* determined by the stock item. Otherwise, the button does not have a label.
*
* The icon of a #GtkToolButton is determined by the properties
* #GtkToolButton:icon-widget and #GtkToolButton:stock-id. If
* #GtkToolButton:icon-widget is non-%NULL, then
* that widget is used as the icon. Otherwise, if #GtkToolButton:stock-id is
* non-%NULL, the icon is determined by the stock item. Otherwise,

*
* - The use_underline property only has an effect when the label
* on the toolbutton comes from the label property (ie. not from
* label_widget or from stock_id).
*
* In that case, if use_underline is set,
*
* - underscores are removed from the label text before
* the label is shown on the toolbutton unless the
* underscore is followed by another underscore
*
* - an underscore indicates that the next character when
* used in the overflow menu should be used as a

*

* the form "_Open" and the toolbar should take appropriate
