How to debug QGIS using PyScripter IDE?
Debugging using Pyscripter IDE (Windows) ¶ For using Pyscripter IDE , here’s what you have to do: Make a copy of qgis-unstable.bat and rename it pyscripter.bat. Open it in an editor. And remove the last line, the one that starts QGIS.
What can you do with pyqgis in Python?
QGIS provides a Python API (Application Programming Interface), commonly known as PyQGIS. The API is vast and very capable. Almost every operation that you can do using QGIS – can be done using the API. This allows developers to write code to build new tools, customize the interface and automate workflows.
How to customize the QGIS interface in Python?
We will also explore GUI programming techniques for customizing the QGIS interface using Qt widgets. This course requires basic knowledge of Python. If you are not familiar with Python, it is strongly recommended you complete our Python Foundation for Spatial Analysis course. We will build upon the exercises covered in that course.
Where do I find the batch file for QGIS?
On Windows, you need to make sure that you have the same environment settings and use the same libraries and interpreter as QGIS. The fastest way to do this is to modify the startup batch file of QGIS. If you used the OSGeo4W Installer, you can find this under the bin folder of your OSGeo4W install.
Where to find remote debugging plugins in QGIS?
There is some preparation to be done on QGIS itself. Two plugins are of interest: Remote Debug and Plugin reloader. Go to Plugins ‣ Manage and Install plugins… Search for Remote Debug ( at the moment it’s still experimental, so enable experimental plugins under the Options tab in case it does not show up).
Which is the best IDE for writing QGIS plugins?
PyCharm is an IDE for Python developed by JetBrains. There is a free version called Community Edition and a paid one called Professional. You can download PyCharm on the website: https://www.jetbrains.com/pycharm/download We are assuming that you have compiled QGIS on Ubuntu with the given build directory ~/dev/qgis/build/master.
How does the remote debug plugin in Eclipse work?
Eclipse is now waiting for a connection from QGIS to its debug server and when QGIS connects to the debug server it will allow it to control the python scripts. That’s exactly what we installed the Remote Debug plugin for.
Why does eclipse know about the QGIS API?
A very handy feature is to have Eclipse actually know about the QGIS API. This enables it to check your code for typos. But not only this, it also enables Eclipse to help you with autocompletion from the imports to API calls. To do this, Eclipse parses the QGIS library files and gets all the information out there.
Where to find QGIS core DLL in Windows?
To prepare your environment for using Eclipse in Windows, you should also create a batch file and use it to start Eclipse: Locate the folder where qgis_core.dll resides in. Normally this is C:\\OSGeo4W\\apps\\qgis\\bin, but if you compiled your own QGIS application this is in your build folder in output/bin/RelWithDebInfo
