NAME

Splitter.short - splits a View in up to four panes

DESCRIPTION

A Splitter is able to split a View in up to four panes that show disconnected portions of the View and can be scrolled independently. The View is simultaneously installed in four Scrollers whose size can be changed by moving the splitbars.
The installed VObject must be a View because only the class View implements the functionality to be displayed in more than one Clipper.
Splitters can be used, for example, when the initial window layout is created:

Window *MyDocument::DoMakeWindows()
{
    View *myView = new MyView(/* ... */);
    return new Window(this, Point(400), eWinDefault,
               new Splitter(myView));
}

See also class Clipper and class Scroller.

classes are rarely derived from Splitter.
class Splitter is often reused directly.
class Splitter contains 12 methods.

owner of class:: nobody.
baseclasses:: CompositeVObject
flags:: CompositeVObjectFlags

INSTANCE VARIABLES
