Window Styles
-------------
    ======================  ============================================
    wx.CLRP_DEFAULT         Default style.
    wx.CLRP_USE_TEXTCTRL    Creates a text control to the left of the
                            picker button which is completely managed
                            by the `wx.ColourPickerCtrl` and which can
                            be used by the user to specify a colour.
                            The text control is automatically synchronized
                            with the button's value. Use functions defined in
                            `wx.PickerBase` to modify the text control.
    wx.CLRP_SHOW_LABEL      Shows the colour in HTML form (AABBCC) as the
                            colour button label (instead of no label at all).
    ======================  ============================================

Events
------
    ========================  ==========================================
    EVT_COLOURPICKER_CHANGED  The user changed the colour selected in the
                              control either using the button or using the
                              text control (see wx.CLRP_USE_TEXTCTRL; note
                              that in this case the event is fired only if
                              the user's input is valid, i.e. recognizable).
