/**
    @class wxColourPickerCtrl

    This control allows the user to select a colour. The generic implementation
    is a button which brings up a wxColourDialog when clicked. Native
    implementation may differ but this is usually a (small) widget which give
    access to the colour-chooser dialog. It is only available if
    @c wxUSE_COLOURPICKERCTRL is set to 1 (the default).

    @beginStyleTable
    @style{wxCLRP_DEFAULT_STYLE}
           The default style: 0.
    @style{wxCLRP_USE_TEXTCTRL}
           Creates a text control to the left of the picker button which is
           completely managed by the wxColourPickerCtrl and which can be used
           by the user to specify a colour (see SetColour). The text control
           is automatically synchronized with button's value. Use functions
           defined in wxPickerBase to modify the text control.
    @style{wxCLRP_SHOW_LABEL}
           Shows the colour in HTML form (AABBCC) as colour button label
           (instead of no label at all).
    @style{wxCLRP_SHOW_ALPHA}
           Allows to select opacity in the colour-chooser (effective under
           wxGTK and wxOSX).
    @endStyleTable

    @beginEventEmissionTable{wxColourPickerEvent}
    @event{EVT_COLOURPICKER_CHANGED(id, func)}
           The user changed the colour selected in the control either using the
           button or using text control (see @c wxCLRP_USE_TEXTCTRL; note that
           in this case the event is fired only if the user’s input is valid,
           i.e. recognizable).
