Description
Is an OnLayerMouseDown event dispatcher.
Override the protected LayerMouseDown method to provide other responses in addition to calling the OnLayerMouseDown event handler when the user presses a mouse button while the cursor's hot spot is over the 3D layer.
A 3D control calls LayerMouseDown in response to any mouse-down events, decoding the message parameters into the shift key state and position, which it passes in the Shift, X, and Y parameters, respectively. The value of the Button parameter indicates which mouse button was pressed: left, right, or middle.
