Dear (processing) developers,
for my plugin (IO Geopaparazzi), I need to stop the execution of an
external thread when the user presses the X button of the form.
I though to overload the closeEvent in this way:
from processing.gui.AlgorithmDialog import AlgorithmDialog
[omitted]
class ExportTilesAlgorithm(GeoAlgorithm):
[omitted]
# get the AlgorithmDialog dialog object and overload the closeEvent
AlgorithmDialog.closeEvent = self.closeEvent
[omitted]
def closeEvent(self, evt):
# necessary to close the thread before it is finished
self.workThread.stop()
it works perfectly but I'm not sure that it will not induce anomalous
behaviours in other geoalgorithms as the original function is (from
AlgorithmDialog.py) :
def closeEvent(self, evt):
QgsMapLayerRegistry.instance().layerWasAdded.disconnect(self.mainWidget.layerAdded)
QgsMapLayerRegistry.instance().layersWillBeRemoved.disconnect(self.mainWidget.layersWillBeRemoved)
super(AlgorithmDialog, self).closeEvent(evt)
Any suggestions?
Thank you
enrico
