Is there some way for QT Designer to browse for only GIS data, much like the QGsFileWidget. I need the user to be able to select only .shp, .sqlite, and features in .gdb or .gpkg files.
There used to be a qbrowser in Qgis version2 but it had been removed in version3.
This will be for a stand alone python program. Qgis will not be open when this is happening.
