[Gambas-user] TextEdit control has disappeared

[Rolf-Werner Eilert]

In a dialog of one of my projects, there has been a TextEdit control to 
enable the user to type in RichText and save/reload it.

I made a new install in a new Kubuntu 20.04 (from the team repos), and 
now the project refuses to load the class for the dialog because there 
is no TextEdit control anymore. :-/

How can I load the dialog's form to replace the control?

Or better, how can I get that control back?

Thanks for your help
