gtkToolItemSetIsImportant {RGtk2} | R Documentation

## gtkToolItemSetIsImportant

### Description

Sets whether `tool.item` should be considered important. The `GtkToolButton` class uses this property to determine whether to show or hide its label when the toolbar style is `GTK_TOOLBAR_BOTH_HORIZ`. The result is that only tool buttons with the "is_important" property set have labels, an effect known as "priority text"
