KXYSelector is the base class for other widgets which provides the ability to choose from a two-dimensional range of values. The currently chosen value is indicated by a cross. An example is the KHSSelector which allows to choose from a range of colors, and which is used in KColorDialog.
A custom drawing routine for the widget surface has to be provided by the subclass.
