EventButtonRef

public struct EventButtonRef : EventButtonProtocol

The EventButtonRef type acts as a lightweight Swift reference to an underlying GdkEventButton instance. It exposes methods that can operate on this data type through EventButtonProtocol conformance. Use EventButtonRef only as an unowned reference to an existing GdkEventButton instance.

Used for button press and button release events. The type field will be one of GDK_BUTTON_PRESS, GDK_2BUTTON_PRESS, GDK_3BUTTON_PRESS or GDK_BUTTON_RELEASE,

Double and triple-clicks result in a sequence of events being received. For double-clicks the order of events will be:

  • GDK_BUTTON_PRESS
  • GDK_BUTTON_RELEASE
  • GDK_BUTTON_PRESS
  • GDK_2BUTTON_PRESS
  • GDK_BUTTON_RELEASE

Note that the first click is received just like a normal button press, while the second click results in a GDK_2BUTTON_PRESS being received just after the GDK_BUTTON_PRESS.

Triple-clicks are very similar to double-clicks, except that GDK_3BUTTON_PRESS is inserted after the third click. The order of the events is:

  • GDK_BUTTON_PRESS
  • GDK_BUTTON_RELEASE
  • GDK_BUTTON_PRESS
  • GDK_2BUTTON_PRESS
  • GDK_BUTTON_RELEASE
  • GDK_BUTTON_PRESS
  • GDK_3BUTTON_PRESS
  • GDK_BUTTON_RELEASE

For a double click to occur, the second button press must occur within ¼ of a second of the first. For a triple click to occur, the third button press must also occur within ½ second of the first button press.

    Untyped pointer to the underlying `GdkEventButton` instance.

    For type-safe access, use the generated, typed pointer _ptr property instead.
