[Qt-interest] Designer plugins and "Promoted Widgets"

[Friedemann Kleint]

Hi Giacomo,

This is currently not  possible since promoted widgets and custom widgets are 
two sides of a coin:

If Designer finds a plugin, it creates the custom widget using its factory 
method. If it cannot find the plugin, it treats the widget as promoted from the 
base class (which then must be one of the available Qt widgets).
Thus, you cannot further promote custom widgets.

Regards,
Friedemann
