Description

button specifies which mouse button was pressed. 1 for the left mouse button, 2 for the right mouse button, and 4 for the middle mouse button.

shift specifies an integer corresponding to the state of the SHIFT (bit 0), CTRL (bit 1) and ALT (bit 2) keys. When none, some or all of these keys are pressed none, some or all the bits get set. These bits correspond to the values 1, 2, and 4, respectively. For example, if both SHIFT and ALT were pressed, ShiftState would return 5.

x is the X coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the SceneControl (the top left hand corner).

y is the Y coordinate, in pixels, where the mouse button was pressed referenced against the origin (0, 0) of the SceneControl (the top left hand corner).

Remarks

The OnDoubleClick event is triggered when the user releases and presses a mouse button and then presses and releases it again on the SceneControl. If the double click does not occur within the system's double click time limit, the SceneControl will recognise another OnMouseDown event. Otherwise the event sequence is as follows:

OnMouseDown
OnMouseUp
OnDoubleClick
OnMouseUp
