The graphics part of the Gargoyle window is a new viewer of class $ActionArea. The paint proc for a $ActionArea is defined herein. Stone, July 15, 1985 11:39:29 am PDT ViewerClasses.PaintProc whatChanged is a GargoyleData. self is an ActionArea. viewer is the ActionArea. The camera for this view represents the translation from the center of the window in screen dots and a scaling factor. Find the center of the ActionArea in viewer coordinates. Initialize the context to white. Create the Container and the top menu which looks like this: Clear, Reset, Get, Store, Save, Split, Erase Construct the outer container. Create an ActionArea which fills the bottom of the Gargoyle Container ‌تکIheadڑœ™Iprocڑœ1™1Jڑœ دmœ1™LڑœE™Eڑœ1ک1LڑœکڑœکLڑœکLڑœکLڑœکLڑœںAک\LڑœکLڑœ‍کLڑœک—Lڑœک—LڑœEکELڑœEکELکLڑœGکGLکLڑœںک—Lکڑ œ‍œ‍œ!ک
