PaintGL and GLWidget
Hello, first of all thanks for your job. It's amazing and I can't wait to test it and realize something out of it. Unfortunately I have an issue: The program runs: the interface opens but on display remain white and nothing appear, in the terminal I have this error:
Traceback (most recent call last):
File "Tsugite_app.py", line 92, in paintGL
self.display.update()
AttributeError: 'GLWidget' object has no attribute 'display'
All the dependency looks satisfied. I didn't find any content on forums so here I am.
I using Ubuntu 20.04.1 LTS, 64-bit. Thanks for your time
Dear Stuffnex, Great to hear that you are testing it out! I am using windows 10, and it works. Unfortunately, I do not know the answer to your question. If you find an answer, maybe post it here as it might be of interest for others. Otherwise, maybe try running the code on Windows 10 (or the executable file available for download from the project website, also for Windows 10). Hope it works out. /Maria
I had the same issue in my laptop, but it runs well in my desktop, only difference is my desktop has a dedicated GPU I don't know if it makes sense to you
Interesting..... I honestly don't know anything about how computer hardware might effect the program. It is also hard for me to debug this issue, because it works on my computer (both laptop and desktop).
One thing I would suspect as a possible reason is that there are different installation modes of opengl (https://pypi.org/project/PyOpenGL/).
$ pip install PyOpenGL PyOpenGL_accelerate $ pip install PyOpenGL ... (maybe others)
If anybody finds a solution, please post it here to help other people with the same issue!
I did install the ones you mention, and this happens, also noted the one use in my desktop is the executable, haven't tried to run the code

hmm.. maybe the issue is that I have a variable called "display" and "Display" (with a capital D) is already a taken name by opengl. I will change the name of my variable to see if that helps... Ill let you know when it is done.
Just to double check versions... pip show pyopengl (command line) gives this result. Do you have the same installation of PyOpenGl?

Yes is the same

Hi, I have an update. I made some tests, updated all the requirements up to the right version and downloaded the new code.
I believe we're on the right way. Maybe because linux is case-sensitive? Now I have another error, with same effect on the UI, I can see a pattern in here: might be another capital letter in a variable like "d/Display"?
Traceback (most recent call last): File "Tsugite_app.py", line 92, in paintGL self.show.update() AttributeError: 'builtin_function_or_method' object has no attribute 'update'
Might it be a good lead? Thank you!

Well here is your problem from one error:
OpenGL.GL.shaders.ShaderCompilationError: ('Shader compile failure (0): b"ERROR: 0:4: '#extension' : 'GL_ARB_explicit_uniform_location' is not supported
If this from your laptop, it's gpu may not support the features needed by a shader. This would explain why a discrete desktop gpu worked.
@stuffnex
Could you try now my fork? I have made some changes and it works well for me on Linux (blackPanther OS).
@hmikihth, thank you for your work, unfortunately I still have the same output as before:
AttributeError: 'builtin_function_or_method' object has no attribute 'view'
Traceback (most recent call last):

if self.show.view.dragged:

Again, UI loads in no time tho the frame where the joint should be displayed is blank see this screenshot if might help... I was so excited for this app.. It's a pain to not make it work on my laptop..
Thank you all for your support, please come ahead if you have insights!
Hi, I see the line numbers are not the same, so that was not my fork. I guess you do not have the hashbang (#!/usr/bin/env python3) in the first line, and maybe you started it with python2 instead of python3.
How did you start the script?
python tsugite_app.py
OR
python3 tsugite_app.py
OR
./tsugite_app.py
And did you try it in virtualenv?
Linux build for container exposing the app through the browser (no hardware acceleration, "softpipe" rendering) works around hardware issues with graphics drivers at the cost of slower rendering, see https://github.com/marialarsson/tsugite/pull/25.
