Details about the "op" parameter :
 +
Parameter op takes one of the strings “set”, “reset”, “intersect”, or “null”.
 +
* '''reset'''        sets the clipping rectangle to include the entire window. The remaining parameters is ignored and can be left out.
 +
* '''set'''            sets the clipping rectangle to the x, y coordinates with the specified width and height. The remaining parameters default to the system window location and size.
 +
* '''intersect'''  sets the clipping rectangle to the intersection of the current clipping rectangle with the rectangle specified in the routine parameters. <b>It has been removed in platform.apilevel = 2.0 ([[Changes in OS 3.2|OS 3.2]])</b>
 +
* '''null'''          sets the clipping rectangle to empty. All subsequent graphics commands will be ignored.
 +
Typically the “set” operation is called before drawing, say, a text string. It is important to call the “reset” operation after drawing the last clipped graphic so that you don’t leave a lingering clipping rectangle as a side effect.
