Set up a file filter in QT Designer for QGSFileWidget

Question

How would I set a file filter for QGSFileWidget for multiple file types, xlsx, csv etc

I've worked out where:

But I'm unsure what the string needs to look like - what separator to use etc? I'm new to QT Designer and I'm not sure where to find documentation with examples on the widgets

Answer 1

Documentation is here: https://qgis.org/pyqgis/3.28/gui/QgsFileWidget.html#qgis.gui.QgsFileWidget.setFilter .

Try setting the filter to

All files (*.*);;JPEG (*.jpg *.jpeg);;TIFF (*.tif)

As per the answer https://stackoverflow.com/a/1604542 that relates to the standard QT File Dialog.
