Closed tyrasd closed 3 years ago

I get the following exception when trying to open the dialog window: Python error : An error has occurred while executing Python code: See message log (Python Error) for more details.. This is the stack trace:

An error has occurred while executing Python code:

SlowMo24 commented 3 years ago

I'm sorry but the problem only shifted to a different error message:

@SlowMo24 @tyrasd Really weird. I hoped to just catch the error but it seems as if there is a deeper reason to it. Do you have the same problem when installing orsTools?

@SlowMo24 You're using ubuntu 20.04 as well?

SlowMo24 commented 3 years ago

orsTools (via the plugin repository) works well and yes I'm on 20.04

MichaelsJP commented 3 years ago

I could reproduce it in a VM with Ubuntu 20.04. Solution: Removing the setPlaceholderText for the QcomboBox ohsome_spec_preference_combo fixes it.

Background The setPlaceholderText function was introduced in qt 5.15. many qgis versions still have smaller versions installed and the plugin would therefore crash due to QT not finding the function. The removal does not yield any negative sides for the plugin itself.

MichaelsJP commented 3 years ago

@tyrasd @SlowMo24 looking good for me. please let me know how this works for you. you get the correct version by updating it via qgis to 0.2.1-alpha.

works great! thanks!
