public protocol MouseEventHandler : EventHandler

A protocol describing a mouse event handler object.

  • Main interface to forward mouse down events to the conforming type.

    Declaration

    Swift

    func onMouseDown(_ event: MouseEventArgs)

  • Main interface to forward mouse move events to the conforming type.

    Declaration

    Swift

    func onMouseMove(_ event: MouseEventArgs)

  • Main interface to forward mouse up events to the conforming type.

    Declaration

    Swift

    func onMouseUp(_ event: MouseEventArgs)

  • Main interface to forward mouse enter events to the conforming type.

    Mouse enter is associated with the cursor crossing to the inside of the bounds of a logical screen area occupied by the conforming type, or an object that the conforming type is associated to, as an event handler.

    Declaration

    Swift

    func onMouseEnter()

  • Main interface to forward mouse leave events to the conforming type.

    Mouse leave is associated with the cursor crossing to the outside of the bounds of a logical screen area occupied by the conforming type, or an object that the conforming type is associated to, as an event handler.

    Declaration

    Swift

    func onMouseLeave()

  • Main interface to forward mouse click events to the conforming type.

    Mouse clicks are automatically synthesized by DefaultControlSystem by pairing up a ‘mouse up’ event with a ‘mouse down’ event, in case both events occurred on top of the same event handler.

    Declaration

    Swift

    func onMouseClick(_ event: MouseEventArgs)

  • Main interface to forward mouse scroll events to the conforming type.

    Declaration

    Swift

    func onMouseWheel(_ event: MouseEventArgs)
