  12
  13 This control allows the user to select a colour. The generic implementation is
  14 a button which brings up a \helpref{wxColourDialog}{wxcolourdialog} when clicked. Native implementation
  15 may differ but this is usually a (small) widget which give access to the colour-chooser
  16 dialog.
  17 It is only available if \texttt{wxUSE\_COLOURPICKERCTRL} is set to $1$ (the default).
