When trying to create convex hulls with settings Create convex hull based on input field, the following error pops up after a few seconds and polygon does not get created:

An error has occured while executing Python code:

Traceback (most recent call last):
File "C:\\PROGRA~1\\QGISCH~1\\apps\\qgis\\python\\plugins\\fTools\\tools\\doGeoprocessing.py", line 273, in runRangeFromThread
self.progressBar.setRange( range_vals[ 0 ], range_vals[ 1 ] )
TypeError: QProgressBar.setRange(int, int): argument 2 has unexpected type 'long'

Python version:
2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]

QGIS version:
2.4.0-Chugiak Chugiak, 8fdd08a

I have confirmed that with the same dataset and choosing single minimum convex hull, the polygon is created successfully.

  • Assignee set to Victor Olaya
  • Affected QGIS version changed from 2.4.0 to master
  • Status changed from Open to Feedback
  • Category set to Processing/QGIS

I cannot confirm on QGIS master, can you test it? if you still get the same issue please attach sample data.

meanwhile I can confirm that the same tool in the processing toolbox works only if creating a single convex hull, if the option to create different CHs based on an attribute then the output is empty.

From error message I see, that fTools used, not Processing.

Not reproducible with fTools and Processing

The "ftools" category is being removed from the tracker, changing the category of this ticket to "Processing/QGIS" to not leave the category orphaned.
