  48 This class represents the colour chooser dialog.
  49
  50 Use of this dialog is a multi-stage process.
  51
  52 The actual information about how to display the dialog and the colors in the
  53 dialog's 'registers' are contained in a wx.ColourData instance that is created by
  54 the dialog at init time. Before displaying the dialog, you may alter these settings
  55 to suit your needs. In the example, we set the dialog up to show the extended colour
  56 data selection pane. Otherwise, only the more compact and less extensive colour
  57 dialog is shown.  You may also preset the colour as well as other items.
  58
  59 If the user selects something and selects OK, then the wx.ColourData instance contains
  60 the colour data that the user selected. Before destroying the dialog, retrieve the data.
  61 <b>Do not try to retain the wx.ColourData instance.</b> It will probably not be valid
  62 after the dialog is destroyed.
  63
  64 Along with he wx.ColourDialog documentation, see also the wx.ColourData documentation
  65 for details.
