Design mode in QT Creator only loads QtQuick widgets

[BGrimaud]

Hi,

I'm a bit confused regarding available widgets in the graphical Design mode of Qt Creator.

I am designing a widget-based UI for a Python app. In Qt Creator, I created a new project with a basic app for Python as a template.

However, there are a lot of widgets that I would like to use (e.g. QFileDialog) that aren't available in the drag and drop list to the side.

Looking a bit more into it, the loaded plugins only list libqquickwidget.so which contains QQuickWidget, and looking in Qt/Tools/QtCreator/lib/Qt/plugins/designer only shows said libqquickwidget.so file.

Is there a way to load extra widgets in the Qt Design mode, or am I just confused about its use ?
