This is all inside the command function for a button. I don't close the GUI, I just close the plot window. And then when I try to bring it back up by pressing the button, I get a blank graph. The repeated r.get() calls is a mistake. The whole function (as I am currently testing it) is:

Matplotlib show/draw works only once
I am writing a GUI program in Tkinter which allows the user to enter in different parameters specifying an ellipse segment. Then, he/she presses a button and the ellipse segment is plotted, using matplotlib. Here is the code (inside a class, but logically stands alone) that does this:
...Code:aa = DataArray(self.file0) #Retrieve data sets bb = DataArray(self.file1) #Not used right now cc = DataArray(self.file2)

Big thanks bvdet. This is the part that I ended up using:
Along with the method:Code:top = Toplevel() top.title("Adjust Ellipse") top.protocol("WM_DELETE_WINDOW", self.exit) self.master = master master.withdraw()
...Code:def exit(self): self.master.deiconify() self.master.destroy() #Exit all when 'top' is closedLeave a comment:

How to close "Tk" Window without closing whole GUI
Hi, I am writing a program, in which everything interesting happens in a Toplevel window that I have made. However, whenever I run the program, I get both the standard Tk window and the Toplevel window that I made. How do I get rid of the first Tk window, without closing out of the program completely?
Thanks

Oh, wow, that totally worked. Yeah, I plan to store the file names, but I was just testing it. I still don't understand why the parenthesis would cause the call to the button commands immediately and then never again. Anyways, thanks a lot!Leave a comment:

Tkinter Button Commands are Called Only at Startup?
I am trying to use Tkinter to build a simple GUI app which imports data and performs some analysis. The GUI has just four labels and four buttons side by side. When you press the button, you should get a File Dialog prompt. However, whenever I run the script (see below), Python calls all button commands at startup, and then the buttons don't work afterwards. Even if I write the code without a class, the same thing happens. How do I get it to stop... -
tkFileDialog with tKinter
I am trying to make a simple app to select and operate on data. I am using Tkinter to build a GUI with four labels and four buttons, side by side. However, for some reason when I run the script, all the button commands get called, asking the user to select all files upon startup, and then afterwards the buttons do not work. Here's my code:
