Handler:
on mouseDoubleClick
statements
end mouseDoubleClick
HyperCard sends this message to a button, field, or card after the mouse is clicked twice at the same place. When the message is sent, it's the only one sent during the second click; there's no mouseDown, mouseStillDown, or mouseUp message sent after the first mouseUp.
For HyperCard to send this message, the following conditions must all be true:
(a) The downstroke of a second click follows the downstroke of a previous click within the double-click speed set in the Mouse control panel; and (b) the second click occurs within four pixels of the first; and
(c) the second click occurs within the same object as the first.
If the user clicks repeatedly at the same location faster than the double-click speed set in the Mouse control panel, HyperCard treats each odd-numbered click as a first click and each even-numbered click as a second click.
