This class represents the colour chooser dialog.
Starting from wxWidgets 3.1.3 and currently in the MSW port only, this dialog generates wxEVT_COLOUR_CHANGED events while it is being shown, i.e. from inside its ShowModal
method, that notify the program about the change of the currently selected colour and allow it to e.g. preview the effect of selecting this colour. Note that if you react to this event, you should also correctly revert to the previously selected colour if the dialog is cancelled by the user.
Example of using this class with dynamic feedback for the selected colour:
# Some function for redrawing using the given colour. Ideally, it
# shouldn't do anything if the colour is the same as the one used
# before.
def Redraw(self, colour):
...
def OnColourChanged(self, event):
self.Redraw(event.GetColour())
def SelectNewColour(self):
data = wx.ColourData()
data.SetColour(initialColourToUse)
dlg = wx.ColourDialog(self, data)
dlg.Bind(wx.EVT_COLOUR_CHANGED, self.OnColourChanged)
if (dlg.ShowModal() == wx.ID_OK)
# Colour did change.
else
# Colour didn't change.
# This call is unnecessary under platforms generating
# wx.EVT_COLOUR_CHANGED if the dialog was accepted and unnecessary
# under the platforms not generating this event if it was cancelled,
# so we could check for the different cases explicitly to avoid it,
# but it's simpler to just always call it.
Redraw(data.GetColour())
