Struct gtk::CheckMenuItem [−][src]
pub struct CheckMenuItem(_);
Expand description
A CheckMenuItem is a menu item that maintains the state of a boolean
value in addition to a MenuItem usual role in activating application
code.
A check box indicating the state of the boolean value is displayed
at the left side of the MenuItem. Activating the MenuItem
toggles the value.

╰── <child>
GtkCheckMenuItem has a main CSS node with name menuitem, and a subnode with name check, which gets the .left or .right style class.
Implements
CheckMenuItemExt, GtkMenuItemExt, BinExt, ContainerExt, WidgetExt, glib::ObjectExt, BuildableExt, ActionableExt, WidgetExtManual, BuildableExtManual
Implementations
Creates a new CheckMenuItem with a label.
label
the string to use for the label.
Returns
a new CheckMenuItem.
Creates a new CheckMenuItem containing a label. The label
will be created using Label::with_mnemonic(), so underscores
in label indicate the mnemonic for the menu item.
label
The text of the button, with an underscore in front of the character
Returns
a new CheckMenuItem
Creates a new builder-pattern struct instance to construct CheckMenuItem objects.
This method returns an instance of CheckMenuItemBuilder which can be used to create CheckMenuItem objects.

Tries to cast to an object of type T. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast and upcast will do many checks at compile-time already. Read more
