tkinter.ttk.Progressbar: How to change thickness of a horizontal bar

Question

I am using the ttk.Progressbar in my app. I have scoured the net for an answer but no avail.

I have the following code which is working well. But I want to change the thickness of the bar.

progressbar = ttk.Progressbar(myGui, orient=HORIZONTAL,
                              length=400, mode="determinate",
                              variable=value_progress,
                              )
progressbar.pack()

I want the length to still be 400, but from the top of the bar to the bottom, I wish to decrease that so its half or less then half. (I want my bar on a diet, so to say)

But I am beating my head against the wall to figure out a solution.

Andy ideas? Thanks in advance.

Answer 1

The ttk progress bar appears to lack the width option in Python.

Using a work around (here) for an issue with a Tkinter Button. From this I have been able to create a working solution.

The key to solving the issue was to add the progress bar to a window inside the canvas. Using a window inside the canvas doesn't cause the canvas to resize when the widget is added which means we can control the width of the progress bar.

I have created some working example code:

from ttk import Progressbar
import Tkinter

class Example(Tkinter.Frame):
    def __init__(self, parent):
        Tkinter.Frame.__init__(self, parent)
        self.parent = parent
        self.initUI()

    def initUI(self):
        value_progress =50
        self.parent.title("Progressbar Thingymawhatsit")
        self.config(bg = '#F0F0F0')
        self.pack(fill = Tkinter.BOTH, expand = 1)
                #create canvas
        canvas = Tkinter.Canvas(self, relief = Tkinter.FLAT, background = "#D2D2D2",
                                            width = 400, height = 5)

        progressbar = Progressbar(canvas, orient=Tkinter.HORIZONTAL,
                                  length=400, mode="indeterminate",
                                  variable=value_progress,

                                  )
        # The first 2 create window argvs control where the progress bar is placed
        canvas.create_window(1, 1, anchor=Tkinter.NW, window=progressbar)
        canvas.grid()


def main():
    root = Tkinter.Tk()
    root.geometry('500x50+10+50')
    app = Example(root)
    app.mainloop()

if __name__ == '__main__':
    main()

So to sum up the progress bar is the same size but you just cant see half of it!
