Here we experiment with a gauge or progress bar made from a label displaying a variable number of spaces in color. In this example, we use from 0 to 100 spaces. This label based gauge allows you to choose many different colors, and you can even change the color as the gauge reaches critical levels. The custom gauge is bound to a wx.Slider to test it.

# experiment with a colorful gauge/progress-bar made from a label

        # str3 contains 0 to 100 spaces
        str3 = " " * self.pos1
        self.label3.SetLabel(str3)


app = wx.PySimpleApp()
# create a window/frame, no parent, -1 is default ID, title, size
frame = wx.Frame(None, -1, "test the label-gauge (drag slider)", size = (430, 150))
# call the derived class, -1 is default ID
MyPanel(frame,-1)
# show the frame
frame.Show(True)
# start the event loop
app.MainLoop()

Anyone know of a way to justify the spaces so they fill a horizontal area? I like the effect but getting the "status bar" to scale up (or down) with a window resize would be cool.
