Hi Bernhard, what about
iface.mapCanvas().extentsChanged.connect(lambda: print("the extent has
changed!!!"))
Or something more usefull like
def extent_has_changed_slot():
print(iface.mapCanvas().extent())
iface.mapCanvas().extentsChanged.connect(extent_has_changed_slot)
Btw, the
Hi Gael,
I'm using QGis on Linux Mint, an Ubuntu fork, with no problems, so just
some notes.
- Did you follow
https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu?
- Did you run "sudo apt update" before "sudo apt install"?
- There seems to be an older installation, You
Hi Asim,
I'm surprised that previous QGis versions should have returned three
layers "Gasunie 2, Gasunie Z-509-05 and Wattinfra Kabelverbinding",
because the legend image shows a single vector layer "Overzicht
entities" with three classes, not three separate layers.
According to
Hi Patrick,
what about
iface.mapCanvas().setExtent(layer.extent())
iface.mapCanvas().refresh()
or
iface.setActiveLayer(layer)
iface.zoomToActiveLayer()

Oh my, QGis without GIS functionalities...
Not with on-board resources, I'm afraid, but some thoughts:

Hi Daniela,
possible solution:
1. run the "Union" algorithm that splits the input polygons
2. add a new integer-column to the "Union"-result-layer f. e. "num_overlays"
3. optionally an additional column with type "integer list" or "string",

Hi Julierme,
I think Your problem is, that You try to create a new application with
"app = QApplication(sys.argv)" inside a running QGis, which already is a
running Qt-application.
Simplified code should perform without crash:
import sys
from PyQt5.QtCore import (QSize,Qt)

Hi Simon,
Excel tables don't need to be saved as delimited text, they can be
imported direct to QGis, f.e. with drag
Calculated contents in the spreadsheets are no problem, below my test
with a simple table:

Hello Uwe,
I managed to install and run PCRaster on Windows in the past by
following the YouTube-Video from Hans van der Kwast:

It describes the PCRaster-installation with the *same OSGeo4W-Installer

Hi,
my personal experience with file based data storage in my very private
cloud (something like sharepoint) was, that just opening a Qgis project
with gpg layers causes many uploads, because each access (open, read,
write... ) changes these files. In a multi-user environment this would
Hi,
Python inside QGis has no access to plugins installed by pip if called
from normal shell.
But running "pip install reportlab" from the osgeo4w-shell should do it.
