 The PMW Notebook Widget
#1
I am working in Python 3.7.3. I am trying to make use of the Pmw Notebook widget. When I try to declare a widget of this type it returns the following error:
Error:
Traceback (most recent call last): File "E:\WORK_SPACE\NoteBook_Tester.py", line 26, in <module> nb = pmw.NoteBook(root) File "C:\Users\matta\AppData\Local\Programs\Python\Python37-32\lib\site-packages\Pmw\Pmw_2_0_1\lib\PmwNoteBook.py", line 60, in __init__ Pmw.Color.bordercolors(self, self['hull_background']) File "C:\Users\matta\AppData\Local\Programs\Python\Python37-32\lib\site-packages\Pmw\Pmw_2_0_1\lib\PmwColor.py", line 364, in bordercolors '#%04x%04x%04x' % (lightRGB[0], lightRGB[1], lightRGB[2]), TypeError: %x format: an integer is required, not float
I opened the Pmw.Color class module and replaced the following code:

    return (
        '#%04x%04x%04x' % (lightRGB[0], lightRGB[1], lightRGB[2]),
        '#%04x%04x%04x' % (darkRGB[0], darkRGB[1], darkRGB[2])
    )
with:

    return (
        '#%04x%04x%04x' % (int(lightRGB[0]), int(lightRGB[1]), int(lightRGB[2])),
        '#%04x%04x%04x' % (int(darkRGB[0]), int(darkRGB[1]), int(darkRGB[2]))
    )
By casting the RGB color components to int the widget works. However, I am worried about deployment. Users of my application will be using the original Pmw.Color class. Have I overworked the problem? Is there an easier solution?

Please post all code, output and errors (in it's entirety) between their respective tags. I did it for you this time, Here are instructions on how to do it yourself next time.

What is Pmw, is it compatible with Python 3.7.3, what is the code you are running, can you pass in integers instead of floats in your code.

Pmw referring to python mega widget. When I try to declare a widget of this type it throws the above error. I copied and pasted a number of examples from the web and they threw the same error. From the output error, I opened the pmw.Color module in the Python installation directory and changed the erroneous line with the cast statements, and the widget now appears on the screen. I am hoping there is a top-level fix (basic code, rather than changing the pmw module code)to this problem. Here is my code:

import tkinter as tk
import tkinter.ttk as ttk
import Pmw as pmw

root = tk.Tk()
root.geometry("800x600")
pmw.initialise()

notebook = pmw.NoteBook(root)
notebook.pack(side='top', anchor='w', padx=50, pady=50)
root.mainloop()
Which produces the following error:

Error:
Traceback (most recent call last): File "E:\WORK_SPACE\NoteBook_Tester.py", line 18, in <module> notebook = pmw.NoteBook(root) File "C:\Users\matta\AppData\Local\Programs\Python\Python37-32\lib\site-packages\Pmw\Pmw_2_0_1\lib\PmwNoteBook.py", line 60, in __init__ Pmw.Color.bordercolors(self, self['hull_background']) File "C:\Users\matta\AppData\Local\Programs\Python\Python37-32\lib\site-packages\Pmw\Pmw_2_0_1\lib\PmwColor.py", line 364, in bordercolors '#%04x%04x%04x' % (lightRGB[0], lightRGB[1], lightRGB[2]), TypeError: %x format: an integer is required, not float

https://sourceforge.net/p/pmw/bugs/51/ Wrote:Pmw.Color.bordercolors() fails in Python 3. It seems to be assuming integer division. The clearest demonstration is to invoke directly or run a Notebook demo.

How would I do so (invoke directly)? What would the declaration look like?

Sorry about last post. I did not see the patch at the end of Thomas' post. I went to SourceForge and downloaded fix. I do not know how to run it, and did not want to set up a new account just to ask. Can you please tell me how to open the downloaded file, or install?

Thanks,

Here's a calculator done using pmw and tkinter.
The post below shows what the GUI looks like
