icon

set [the] icon of button ¬ to posInteger set [the] icon of button ¬ to text

where text is the name of an icon.

The icon property returns or sets the icon displayed by a button. Setting it is the same as choosing an icon from the Button Info dialog box. HyperCard sets the function the result to "Can't find that icon." if it can’t find the icon (otherwise the result is empty).

The value of the icon property is an integer corresponding to the ID number of an available icon resource. If a button has no icon, the icon property is 0. For an icon to be displayed on a button, its resource must be available in the current stack, one of the stacks currently being used, the Home stack, or HyperCard itself.
