Instance Method

acceptsFirstMouse(for:)

Returns a Boolean value indicating whether a mouse-down event both activates the window and starts dragging the slider's knob.

Declaration

func acceptsFirstMouse(for event: NSEvent?) -> Bool

Parameters

mouseDownEvent

The mouse-down event.

Return Value

true if the receiver accepts the first mouse-down event; otherwise, false. Returns true by default.

Discussion

If you want the slider to wait for its own mouse-down event, you must override this method.
