Module focus

Expand description

Module for focus-handling functionality. See rat-focus

Macros§

impl_has_focus: Create the implementation of HasFocus for the given list of struct members.
match_focus: Does a match on several fields and can return a result. Does a widget_state.is_focused() for each field and returns the first that is true. There is an else branch too.
on_gained: Does a match on the state struct of a widget. If widget_state.gained_focus() is true the block is executed. This requires that widget_state implements HasFocus, but that’s the basic requirement for this whole crate.
on_lost: Does a match on the state struct of a widget. If widget_state.lost_focus() is true the block is executed. This requires that widget_state implements HasFocus, but that’s the basic requirement for this whole crate.
