KXYSelector Class Reference
from PyKDE4.kdeui import *
Inherits: QWidget → QObject
Subclasses: KHueSaturationSelector
Detailed Description
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.
