fn on_press( self, on_press: impl Into<EventHandler<Event<PressEventData>>>, ) -> Self

This is generally the best event in which to run “press” logic, this might be called onClick, onActivate, or onConnect in other platforms.

Gets triggered when:

• Click: There is a MouseUp event (Left button) with the in the same element that there had been a MouseDown just before
• Touched: There is a TouchEnd event in the same element that there had been a TouchStart just before
• Activated: The element is focused and there is a keydown event pressing the OS activation key (e.g Space, Enter)

fn on_secondary_press( self, on_pointer_press: impl Into<EventHandler<Event<PressEventData>>>, ) -> Self

Also called the context menu click in other platforms. Gets triggered when:

• Click: There is a MouseUp (Right button) event in the same element that there had been a MouseDown just before

fn on_all_press( self, on_press: impl Into<EventHandler<Event<PressEventData>>>, ) -> Self

Gets triggered when:

• Click: There is a MouseUp event (Any button) with the in the same element that there had been a MouseDown just before
• Touched: There is a TouchEnd event in the same element that there had been a TouchStart just before
• Activated: The element is focused and there is a keydown event pressing the OS activation key (e.g Space, Enter)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
