Re: [QGIS-Developer] process bar in processing algs
Thanks guys,
I solved my problem
In particular it was the feedback.progressChanged.connect suggested by
German the missing part.
Cheers

Re: [QGIS-Developer] process bar in processing algs
Hi Pierluigi,
you need to create your own *feedback* object and connect its
*progressChanged* SIGNAL to your progressbar's *setValue* SLOT, in this way:
feedback = QgsProcessingFeedback()
feedback.progressChanged.connect(progressBarGrid.setValue)
params_creategrid = {
# Set key-value parameters
}
result_grid = processing.run("native:creategrid", params_creategrid,
feedback=feedback)

Re: [QGIS-Developer] process bar in processing algs
Hi Pierluigi,
can you please explain me better?
I have self plugin that in particular part use this code
result_grid = processing.run("native:creategrid", params_creategrid)
as explained by Prem, if you want to add the progress when you call a
"native" algorithm of QGIS within your algorithm, then you can pass to
the algorithm parameters:
result_grid = processing.run("native:creategrid", params_creategrid,
context=context, feedback=feedback)
be aware also at the `is_child` parameter. Have a look at the example:
https://docs.qgis.org/3.4/en/docs/user_manual/processing/scripts.html#extending-qgsprocessingalgorithm
if you want to add steps to the progressBar with your logic then you can
use feedback.setProgress(number) to fill the progress bar. Have a look
at the template script and you will find a fine usage
Hope this helps
Matteo

Re: [QGIS-Developer] process bar in processing algs
Hi Mate,
Every processing tool has to implement its business logic in
processAlgorithm() function and it has below syntax.
*def processAlgorithm(self, parameters, context, feedback):*
One of the input parameters is feedback and this as a parameter variable
should be given to the *processing.run()* function as shown below.
Hope, this helps.
result_grid = processing.run("native:creategrid", params_creategrid*,
context=context, feedback=feedback*)

Hi Matteo,
can you please explain me better?
I have self plugin that in particular part use this code
result_grid = processing.run("native:creategrid", params_creategrid)
But I would like to use note the progressBar of processing but a personal
bar in the QDialog
It is possible?

Hi Pierluigi, you can fill the progressBar of the Processing algorithm with feedback.setProgress(integer).

[QGIS-Developer] process bar in processing algs
Dear User,
I have a plugin that call a processing alghoritm
I would like to communicate to the user with a progress bar
below my code:
# native:creategrid
params_creategrid = {
'CRS': crs_layer,
'EXTENT': extent_coords,
'HOVERLAY': 0,
'HSPACING': resolution,
'OUTPUT': 'memory:',
'TYPE': 0,
'VOVERLAY': 0,
'VSPACING': resolution
}
result_grid = processing.run("native:creategrid", params_creategrid)
grid_output = result_grid['OUTPUT']
I would like to show a progressbar in my QprogressBar
called progressBarGrid.
Thanks for your help
Pierluigi
