from Brush to color and back ?

wxPython Users

seems a very simple question,
but I can't find the right information,
and interactive mode gives me problems with wx.

I need to extract the RGB colors form a Brush,
change the color and put them back in the brush.
How is that done ?

thanks,

Hi Stef,

seems a very simple question,
but I can't find the right information,
and interactive mode gives me problems with wx.

change the color and put them back in the brush.
How is that done ?

I would so something like:

oldBrushColour = brush.GetColour()
newBrushColour = self.ManipulateBrushColour(oldBrushColour)
brush.SetColour(newBrushColour)

# Continue painting...

You also need to do

     dc.SetBrush(brush)

again to create a new native brush with the new color and to give that to the DC.

thanks Andrea and Robin,
indeed I needed to create a new brush, and I now do it like this:

    self.Color_On = wx.Brush(Color)
    self.Color_Off = wx.Brush(( Color.Red()//2, Color.Green()//2,Color.Blue()//2))

although there's a lot of data on wxpython.org,
this kind of information is very hard to find.
Some of these pages contains just too much data (not information),
isn't it possible to reduce the data with epydoc ?

cheers,
