(action_tile key expression)

Respond when the user clicks a dialog box tile.

This function assigns the expression to evaluate when the user selects the tile referenced by key. Both expression and key are strings; key is case-sensitive. Expression is typically another LISP function; key refers to the tile. This function operates on tiles that are user-selectable elements of a dialog box, such as radio buttons, check boxes, or buttons.

The expression refers to the tile, using the following arguments:

Argument	Meaning
$value	Current value
$key	Tile name
$data	Application specific data
$reason	Callback reason
$x	Image x-coordinate
$y	Image y-coordinate

Example

Code	Returns
(action_tile "xpt" x_coord)	nil

NOTES

The expression assigned by action_tile overrules the default action of the dialog box (which is assigned via the new_dialog function) and the tile's action attribute.
The command function cannot be called by action_tile.
