Catherine,
You are welcome. I’m glad the course has been helpful to you! You can disregard my last post. I got a little mixed up with the dates and responded to the wrong post in the thread.Is there any way you can record a screen video or share some screenshots of what is happening? It sounds like it is a problem with QGIS but it would be helpful if I can see what is happening to be sure. The procedures for doing the operations are the same for windows as for mac, so your operating system shouldn’t be the problem.
This error is related to building the documentation pages for the plugin. I haven’t been able to find exactly what is causing it, but’s it something internal to pb_tool, not the code we’re creating in this course. It shouldn’t affect your plugin later because it’s not related to the plugin functionality, or code compiling. It’s just related to building the documentation pages. Hope this helps.
Awesome! Thanks for the update.
Sorry for the slow reply. I missed this post.
You are correct. QgsRasterInterface is a base class of QgsRasterDataProvider, which means that QgsRasterDataProvider inherits all the functionality of QgsRasterInterface and adds additional functionality.Glad you were able to figure this out and are enjoying the course. In the future feel free to use contact@opensourceoptions.com if you can’t upload something to this forum.
I’m pretty sure it’s not a problem with your computer. Have you tried to uninstall and reinstall QGIS? If so and you’re having the same problems would you be able to send a video or screenshots that show what’s happening? If you’re not able to upload to this forum email to contact@opensourceoptions.com
Could you show me a screenshot of the full symbology window? If I can see what it looks like I might be able to walk you through it.
I’m sorry you’re having troubles. Which QGIS version are you using? Is it the most recent one? My first suggestion would be uninstall QGIS then reinstall. I can search around to see if I find others with the same problem that found solutions.
That’s something you can do with PyQGIS. This YouTube video can help get you started https://youtu.be/NgvdgjyY03s.
I also have an entire course that will get you started with PyQGIS programming. This will cover a lot of code that will help you develop the analysis and processing behind your plugin. https://opensourceoptions.com/course/pyqgis-learn-the-qgis-python-api/
Ok, I see. iface is a built-in class that references your current QGIS interface. The PyQGIS API can also be used to build a custom GIS program that has its own interface (not QGIS). What that means, is that anytime you’re using PyQGIS within QGIS iface will refer to the QGIS interface. iface is an instance of QgisInterface. Hope that helps.
For more examples, you can look at the PyQGIS developer guide (it should be linked in the lessons).
Hi James,
I’m not totally sure I understand your question. Could you elaborate a little more or give an example if you have one?Can you let me know which lesson you are working on?
Hi Nick, Glad you were able to figure things out. And my apologies for the slow response. Was it a problem with the course code? If so, I’ll make sure it gets updated.
You should look at the documentation or some examples for QSpinBox. You need to use the value() function to get a value from a spin box.
