Expand description

An interface for manipulating the selection, to be used by the implementor of the toolbar widget.

Required Methods§

Source

fn text_editing_value(self: Handle<Self>, app: &App) -> TextEditingValue

Gets the current text input.

Source

fn user_update_text_editing_value( self: Handle<Self>, app: &mut App, value: TextEditingValue, cause: SelectionChangedCause, )

Indicates that the user has requested the delegate to replace its current text editing state with value.

The new value is treated as user input and thus may subject to input formatting.

Source

fn hide_toolbar(self: Handle<Self>, app: &mut App, hide_handles: bool)

Hides the text selection toolbar.

By default, hide_handles is true, and the toolbar is hidden along with its handles. If hide_handles is set to false, then the toolbar will be hidden but the handles will remain.
