Hi all,
I'm porting an existing Geoprocessing Algorithm plugin to QGIS 3 and I'm
having some trouble customizing the default dialog.
On QGIS 2.x the following code worked:
class TestAlgorithm(GeoAlgorithm):
> INPUT = 'INPUT'
> OUTPUT = 'OUTPUT'
>
>
def getCustomParametersDialog(self):
> customDialog = AlgorithmDialog(self)
> customDialog.textShortHelp.setFixedWidth(450)
> return customDialog
>
On QGIS 3 however, the getCustomParametersDialog() method is gone. I
assumed it was replaced by the new createCustomParametersWidget(), but
unfortunately this method doesn't seem to get called by the parent class:
def createCustomParametersWidget(self, parent):
> customDialog = AlgorithmDialog(self)
> customDialog.textShortHelp.setFixedWidth(450)
> return customDialog
>
I also tried manually creating the dialog, but I get a message saying that
the *'AlgorithmDialog' object has no attribute 'textShortHelp'.*
alg =
> QgsApplication.processingRegistry().algorithmById('test:testAlgorithm')
> dlg = AlgorithmDialog(alg)
> dlg.textShortHelp.setFixedWidth(450)
> dlg.show()
>
Any thoughts?
Thanks in advance!
André
