wxPython Custom Gauge

vegaseat 1 Tallied Votes 581 Views Share

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.

# wxPython:
# experiment with a colorful gauge/progress-bar made from a label
# (note wx.Gauge() comes only in green)
# tested with Python24 and wxPython26     vegaseat     21feb2006

import wx

class MyPanel(wx.Panel):
    class MyPanel creates a panel with a slider, a gauge/progress bar
    made from a label and a variable number of spaces
    def __init__(self, parent, id):
        # create a panel
        wx.Panel.__init__(self, parent, id)

        # default id = -1 is used, initial value = 50, min value = 0, max value = 100
        self.slider1 = wx.Slider(self, -1, 50, 0, 100, (10, 10), (400, 50),
            wx.SL_HORIZONTAL | wx.SL_AUTOTICKS | wx.SL_LABELS)

        # set gauge to initial slider position
        self.pos1 = self.slider1.GetValue()

        # this label is used for a simple colorful gauge
        # str3 has 0 to 100 spaces, each space is one tickmark
        # you might have to factor that for different sizes
        str3 = " " * self.pos1
        self.label3 = wx.StaticText(self, -1, str3, (10, 80))
        # respond to changes in slider position ...
        self.slider1.Bind(wx.EVT_SLIDER, self.sliderUpdate)

    def sliderUpdate(self, event):
        # get the slider position
        self.pos1 = self.slider1.GetValue()
        # optionally change the color of the label-gauge
        if self.pos1 > 80:

        # set the label-gauge position
        # str3 contains 0 to 100 spaces
        str3 = " " * self.pos1

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
# show the frame
# start the event loop

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.
