Detailed Description

A menu_button is a styled_widget to choose an element from a list of elements.

When a menu_button has a return value it sets the return value for the window. Normally this closes the window and returns this value to the caller. The return value can either be defined by the user or determined from the id of the menu_button. The return value has a higher precedence as the one defined by the id. (Of course it's weird to give a menu_button an id and then override its return value.)

When the menu_button doesn't have a standard id, but you still want to use the return value of that id, use return_value_id instead. This has a higher precedence as return_value.

List with the menu_button specific variables:

Key Type Default Description
return_value_id string "" The return value id.
return_value int 0 The return value.

The following states exist:
