Expand description

A trait defining event callbacks.

Required Methods

Provided Methods

Default implementation emulates mouse clicks

Represents raw hardware mouse motion event Note that these events are delivered regardless of input focus and not in pixels, but in hardware units instead. And those units may be different from pixels depending on the target platform

This event is sent when the userclicks the window’s close button or application code calls the ctx.request_quit() function. The event handler callback code can handle this event by calling ctx.cancel_quit() to cancel the quit. If the event is ignored, the application will quit as usual.
