\section{\class{wxColourPickerCtrl}}\label{wxcolourpickerctrl}

This control allows the user to select a colour. The generic implementation is
a button which brings up a \helpref{wxColourDialog}{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 \texttt{wxUSE\_COLOURPICKERCTRL} is set to $1$ (the default).

\wxheading{Window styles}

\twocolwidtha{5cm}%
\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxCLRP\_DEFAULT\_STYLE}}{The default style: 0.}
\twocolitem{\windowstyle{wxCLRP\_USE\_TEXTCTRL}}{Creates a text control to the left of the
picker button which is completely managed by the \helpref{wxColourPickerCtrl}{wxcolourpickerctrl}
and which can be used by the user to specify a colour (see \helpref{SetColour}{wxcolourpickerctrlsetcolour}).
The text control is automatically synchronized with button's value. Use functions defined in \helpref{wxPickerBase}{wxpickerbase} to modify the text control.}
\twocolitem{\windowstyle{wxCLRP\_SHOW\_LABEL}}{Shows the colour in HTML form (#AABBCC) as colour button label
(instead of no label at all).}
\end{twocollist}

\wxheading{Event handling}

To process a colour picker event, use these event handler macros to direct input to member
functions that take a \helpref{wxColourPickerEvent}{wxcolourpickerevent} argument.

\twocolwidtha{7cm}%
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf EVT\_COLOURPICKER\_CHANGED(id, func)}}{The user changed the
colour selected in the control either using the button or using text control
(see wxCLRP\_USE\_TEXTCTRL; note that in this case the event is fired only if
the user's input is valid, i.e. recognizable). }

\wxheading{Event handling}

To process input from a wxColourPickerCtrl, use one of these event handler macros to
direct input to member function that take a

\constfunc{wxColour}{GetColour}{\void}

Retrieve the colour the user has just selected.
