Struct titanium::desktop::gui::libdruid::widget::Click

pub struct Click<T> { /* private fields */ }

A clickable Controller widget. Pass this and a child widget to a ControllerHost to make the child interactive. More conveniently, this is available as an on_click method via WidgetExt.

This is an alternative to the standard Button widget, for when you want to make an arbitrary widget clickable.

The child widget will also be updated on LifeCycle::HotChanged and mouse down, which can be useful for painting based on ctx.is_active() and ctx.is_hot().
