Hello!
I am facing difficulties trying to set the text of a QgsLayoutItemLabel.
I do something like the following to load a .qpt composer template and
print this to a .png file (which works)
path = "C:\\QGIS3\\apps\\qgis\\composer_templates"
template_file = open(path+"\\ANSR_print_composer2.qpt")
template_content = template_file.read()
template_file.close()
document = QDomDocument()
document.setContent(template_content)
composition = QgsLayout(QgsProject.instance())
composition.loadFromTemplate(document, QgsReadWriteContext())
map_item = composition.itemById('map')
legend_item = composition.itemById('legend')
text_item = composition.itemById('textbox')
QgsLayoutExporter(composition).exportToImage( path+"\\report.png",
QgsLayoutExporter.ImageExportSettings())
And now I’d like to modify only the text of the QgsLayoutItemLabel,
which is the “textbox”:
1)I can move it around with setX(), setY(), but I don’t know how to
edit the text of the label. I thought of something like
text_item.setText() or text_item.setLabelText(), but I think that
text_item is just an instance of QgsLayoutItem, not
QgsLayoutItemLabel. And there I get stuck.
2)How would you manually add another text label, set the main property
etc, such that, at the end of the day, my above code would export a
.png containing this QgsLayoutItem?
I would have begun this way:
new = QgsLayoutItemLabel(composition)
new.setText(“New label”)
But it does not quite work that way!
Would be of great help, if you could give me some hints on that.
Thank you in advance! J
Hannes

[QGIS-Developer] Processing algorithm plugin help
Hi all, I developed a processing algorithm plugin using the Plugin Builder but I'm having trouble setting up the Help panel which usually shows on the right side of the windows, or at least the a help button pointing to a static file. I've tried creating the .py.help file with the same name as my algorithm and provider files and placing them in both the "~/.qgis2/processing/scripts" and "~/.qgis2/python/plugins/my_plugin" folders, but without success. Implementing the helpString() and helpUrl() methods in my GeoAlgorithm class didn't work either. Am I missing something? Sorry if it's a noob question.

Re: [QGIS-Developer] Processing algorithm plugin help
I was already doing something quite similar but unfortunately it still
doesn't work. No help panel and no help button, just the parameters.
Is there anything else I should do on the defineCharacteristics() method
maybe?
As for the QGIS version, I'm still using 2.18. Could this be the problem?
Thanks for the input!
