This control allows the user to select a colour. The
implementation varies by platform but is usually a button which
brings up a `wx.ColourDialog` when clicked.
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).
