ABSTRACT:
A separate window is provided for each of multiple OpenDoc Canvas objects, thereby effecting a multiple Canvas-per-compound document design. Possibility of one OpenDoc object drawing in another object's screen area is eliminated by clipping imposed by the Xserver on a perwindow basis. Multiple different X-rendering libraries may be employed for screen imaging. The raw XWindow may be used for direct Xlib drawing functions and other rendering toolkits. Widgets associated with alternative graphical user interfaces may be used as the root of a widget hierarchy.
