Class MouseButtonEvent

java.lang.Object
  gui.mouse.MouseButtonEvent

public class MouseButtonEvent
extends java.lang.Object

Static methods for determining whether certain mouse button events have taken place. This class hides the messiness of checking mouse events on Mac, where the swing utilities are buggy in JDK1.3.1 but ok in JDK1.4.

With JDK1.3.1: On a ONE-button Mac: - ctrl-click and option(alt)-click both answer true to isMiddleButton. I interpret this as a RIGHT mouse event (pop up menu). - apple(cloverleaf)-click answers true to isRightButton. I interpret this as a MIDDLE mouse event (center the display).

On a FIVE-button Mac: - The right of the middle three buttons answers false to isRightButton and true to isMiddleButton. I interpret this as a RIGHT mouse event. - The middle (wheel) button answers false to isRightButton, false to isMiddleButton, and true to isLeftButton. I don't see any logical way to make this behave as anything other than a left click (selection), since the event appears identical to a left click in every aspect I've checked. - The left of the three middle buttons answers true to isLeftButton. Fine. - The far-left buttons (on the side of the mouse--buttons I wouldn't normally use) answer true to isRightButton, false to the others. This gets treated as MIDDLE button (center the display).

(Although this isn't currently used here, note that Windows responds TRUE to isAltDown when it's not (and false when it is!) and same with isControlDown.)
