Flashing text in wxPython

I was wondering if anyone knows a way to program flashing text into wxPython? (I am fairly new to wxPython) It would flash between red and normal every half second or so, I am using Python 2.7.3, not the most recent release.

Thanks

Chris

You'll want to look at how to change fonts on the fly. Typically, it's just calling the widget's SetFont() method. Since you want to do this on a regular basis, then you'll almost certainly want to use a wx.Timer. You can read my tutorial on that subject, if you want. I would probably use the StaticText widget.

Update: Here's a silly example:

import random
import time
import wx

########################################################################
class MyPanel(wx.Panel):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)

        self.font = wx.Font(12, wx.DEFAULT, wx.NORMAL, wx.NORMAL)
        self.flashingText = wx.StaticText(self, label="I flash a LOT!")
        self.flashingText.SetFont(self.font)

        self.timer = wx.Timer(self)
        self.Bind(wx.EVT_TIMER, self.update, self.timer)
        self.timer.Start(1000)

    #----------------------------------------------------------------------
    def update(self, event):
        """"""
        now = int(time.time())
        mod = now % 2
        print now
        print mod
        if mod:
            self.flashingText.SetLabel("Current time: %i" % now)
        else:
            self.flashingText.SetLabel("Oops! It's mod zero time!")
        colors = ["blue", "green", "red", "yellow"]
        self.flashingText.SetForegroundColour(random.choice(colors))

########################################################################
class MyFrame(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Flashing text!")
        panel = MyPanel(self)
        self.Show()

#----------------------------------------------------------------------
if __name__ == "__main__":
    app = wx.App(False)
    frame = MyFrame()
    app.MainLoop()
