python font pixel size

Hello,

I am trying to scroll text from a text file across a wx.panel.

This is the code so far:

Code:

    def scrolling(self, text, rate):
        def scroll():
            charList = []
            dc = wx.ClientDC(self.panel_1)
            open_text = open(text, "rb")
            my_text = open_text.read()
            charList.append(my_text)
            open_text.close()
            x,y = self.panel_1.GetClientSizeTuple()
            while 1:
                for z in charList:
                    for r in range(2000):
                        dc.DrawText(z,x-r,0)
                        time.sleep(rate)
                        dc.Clear()
        net3 = threading.Thread(target=scroll)
        net3.setDaemon(1)
        net3.start()

It scrolls but I am guessing where the range is (2000). I need to be able to determine the total number of pixels that the text in the file is.

Is there a python way to determine this?

Thanks

I found it

Code:

dc.GetTextExtent()

I am unsure how to mark this post as solved.
