Module wx.lib.agw.cubecolourdialog

The CubeColourDialog is an alternative implementation of wx.ColourDialog, and it offers different functionalities with respect to the default wxPython one. It can be used as a replacement of wx.ColourDialog with exactly the same syntax and methods.

Some features:

And much more.

License And Version:

CubeColourDialog is freeware and distributed under the wxPython license.

Classes
AlphaCtrl Implements the drawing, mouse handling and sizing routines for the alpha channel control.
BaseLineCtrl Base class used to hold common code for the Alpha channel control and the brightness palette control.
BasePyControl Base class used to hold common code for the HSB colour wheel and the RGB colour cube.
BrightCtrl Implements the drawing, mouse handling and sizing routines for the brightness palette control.
Colour This is a subclass of wx.Colour, which adds Hue, Saturation and Brightness capability to the base class.
ColourPanel Simple custom class used to display "old" and "new" colour panels, with alpha blending capabilities.
CubeColourDialog This is the CubeColourDialog main class implementation.
CustomPanel  
HSVWheel Implements the drawing, mouse handling and sizing routines for the HSV colour wheel.
LineDescription Simple class to store description and constants for a line in 2D space.
RGBCube Implements the drawing, mouse handling and sizing routines for the RGB cube colour.
