Additional Comments
Expander triangle

Handle the mouseDown message to perform an action when the user presses the mouse button, before the mouse button is released.

Parameters:

The mouseButtonNumber specifies which mouse button was pressed:

* 1 is the mouse button on Mac OS systems and the left button on Windows and Unix systems.

* 2 is the middle button on Unix systems.

* 3 is the right button on Windows and Unix systems and Control-click on Mac OS systems.

Comments:

The mouseDown message is sent to the control that was clicked, or to the card if no control was under the mouse pointer.

If the Browse tool is being used, and you click an unlocked field with mouse button 1 or 2, no mouseDown message is sent. If you click with button 3, the mouseDown message is sent even though the field is not locked.

Important! If the user clicks a transparent pixel in an image, the mouseDownmessage is sent to the object behind the image, not to the image.
