To change a current 3D button picture without affecting other button settings, call the following statement:
where ButtonName is the 3D button object name, and PictureID is the picture number from the 4D picture library.
Note that there are nine semi-colons after the PictureId number: this insures that other buttom parameters are not changed. Also, the question mark before the PictureID means that the picture is retrieved from the 4D picture library.
Changing the 3D button picture is convenient when emulating multiple states buttons.
