AttributeError: 'NoneType' object has no attribute 'replace' #13

So... this is a bit of legacy code I seem to have missed cleaning up, but for some reason is only causing issues on your home machine. I don't have access to my test wacom tonight but that'll fix it. Effectively the error that is occurring is no wacom cursor device is being found (default set to None in pad.py on line 72), which fails to rename the device name for proper use further down the line. I don't believe there is anything configurable for the cursor (legacy wacom mouse) so I'll likely remove that code and release a new version. |

Thanks for the quick reply. It might not be causing an issue in the school machine because we have a dedicated IT department, so someone might have noticed the issue and fixed it. Not sure if that is what happened or not, but it could be. As for your suggested fix, it does the job. The GUI now loads properly and it works. |

Updated to take into account a cursor isn't detected. Can you please try the new release and let me know if it fixes the issue? |

Happy to report that the new release fixes the issue. As for the school, I don't mind sharing the name. I just have to make sure that me discussing a tool they use is not covered by the NDA we sign at the start of the course. I don't think it is, but I just want to be on the safe side. For the IT department, I am only assuming that they might have made changes to the code since this didn't seem like an issue specific to my system. However, if I find out for sure that they have changed it, I will definitely encourage them to share their changes with you. Thank you very much for your help and quick response. |

Glad it is working correctly for you. I'll leave the issue open for a little for you to respond before closing it off. I don't think it should be an issue as it would be against the spirit of GPL for them to claim using it is covered under their NDA. However, if they have made modifications they can decide whether they want to provide it to me to roll into the main distribution. |

I guess the help page needs to be updated to include info on the new 'Cursor' page/tab ? |
|
I notice you have updated help.html - but the descriptions for 'Touch' and 'Cursor' are swapped ... |
|
Fixed help page gaff (not sure how I swapped those...). New release out with the help page correctly fixed. Closing issue. |
I have just found out about this amazing tool, having used it on my school's computer. I installed it on my home workstation, but every time I run it, I get the following traceback from Python:
QPainter::begin: Paint device returned engine == 0, type: 2 QPainter::font: Painter not active QPainter::setFont: Painter not active QPainter::setPen: Painter not active QPainter::end: Painter not active, aborted Traceback (most recent call last): File "/usr/local/wacom-gui/wacom-gui.py", line 299, in <module> main() File "/usr/local/wacom-gui/wacom-gui.py", line 218, in main window = WacomGui() File "/usr/local/wacom-gui/wacom-gui.py", line 25, in __init__ self.initUI() File "/usr/local/wacom-gui/wacom-gui.py", line 32, in initUI self.cursorControl = pressure(self.pad.Tablet.deviceNames['cursor'], 'cursor') File "/usr/local/wacom-gui/pressure.py", line 312, in __init__ self.tabletName = name.replace('Pad', 'Pen') AttributeError: 'NoneType' object has no attribute 'replace'This happens whether I am running it from the actual source files, or via the installed rpm.
I tried figuring out the problem on my own, since I know a little bit of Python, but without any luck. Any idea, what might be causing this issue.
I am sure it has nothing to do with the tablet itself, as I have tried it with two different ones (both should be supported) and, in both cases, I got the same outcome.
The models I used are:
