Detailed Description

QgisInterface Abstract base class defining interfaces exposed by QgisApp and made available to plugins.

Only functionality exposed by QgisInterface can be used in plugins. This interface has to be implemented with application specific details.

QGIS implements it in QgisAppInterface class, 3rd party applications could provide their own implementation to be able to use plugins.

This method is only needed when using a UI form with a custom widget plugin and calling openFeatureForm or getFeatureForm from Python (PyQt) and you haven't used the info tool first.

Python will crash bringing QGIS with it if the custom form is not loaded from a C++ method call.

This method uses a QTimer to call QUiLoader in order to load the form via C++. You only need to call this once. After that you can call openFeatureForm/getFeatureForm like usual.
