Detailed Description

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 wxUSE_COLOURPICKERCTRL is set to 1 (the default).

Styles

This class supports the following styles:

wxCLRP_DEFAULT_STYLE:
The default style: 0.
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.
wxCLRP_SHOW_LABEL:
Shows the colour in HTML form (AABBCC) as colour button label (instead of no label at all).

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxColourPickerEvent& event)

Event macros for events emitted by this class:

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).
