GtkToolbar::set_style
Sets the text/icon style of the toolbar. This setting is
applied to all buttons on the toolbar, except for the widgets
added via the insert_widget()
function.
You could write your own method which changes the styles of all the widgets
by connecting the toolbar to the "style-changed"
signal.
Every application should let the user decide if he wants
to have icons, text or both displayed in the toolbar.
Note that the toolbar can grow quite large if you use
text+icons the same time. Pay attention to this when creating
your application.
The "style-changed"
signal is emitted when this function is called.
You can read the current style with the
style property.
