I'm making a QGIS plugin that processes a dataset. I started with pluginbuilder and have a GUI that allows me to set what to do.
As my plugin is making changes, when it detects a certain threshold of changes I want it to pop up a dialog with the old and new values and ask whether to apply changes or skip. How do I do that?
The basic structure so far:
if abs(oldCount - newCount) > 10: ????
