Function on_pre_click 

pub fn on_pre_click(
    child: impl IntoUiNode,
    handler: Box<dyn FnMut(&ClickArgs) -> HandlerResult + Send>,
) -> UiNode

P On widget click with the primary button and any click count and the widget is enabled.

This raises only if the click is primary, but raises for any click count (double/triple clicks). Use on_any_click to handle clicks from any button or on_single_click to not include double/triple clicks.

Route

This event property uses the preview route, that is, the handler is called before the children widget handlers and before the $pn_ident handlers.
