Closed petrzhu closed 4 years ago

petrzhu commented 5 years ago

Bug Report

Context

Upon using reloadImage method, Python returns the error

Expected Behaviour

Image widget should be reloaded.

Actual Behaviour

Error.

Any error messages produced by appJar

File "C:\Path\To\Python\Python37-32\lib\site-packages\appJar\lib\tkinter_png.py", line 116, in convert row = row.tolist() #convert from array to list AttributeError: 'list' object has no attribute 'tolist'

Sample code, demonstrating the issue

app.addImage("q", "./q.png")

and then via using thread function app.reloadImage("q", "./q.png")

Version Information

appJar: 0.94.0 Python: 3.7.3 TCL: 8.6, TK: 8.6 Platform: Windows pid: 4900 locale: en_US

And also I attach the way I fixed this issue which works currently: since the 'row' object in file tkinter_png.py is already a list, I just commented out this line and everything works as it should be.

I'm unable to reproduce this in my Mac, I wonder if it is something particular to the image you used?

Could you post a link to the image?

Interestingly, having upgraded the version of pypng (#595) I'm now seeing this issue. So, I'll add in a try/except around that code, so if it cannot be converted to a list, it will continue as is...

I've included the mentioned fix in tkinter_png
