i am new to plugin development and i tried to implement a packageView that only shows filed with certain endings.
This is just a projekts to get used to the developement.
However i have two problems, the first one is that i cant find the Group that holds the diffrent Views (see picture bellow).
The secound one is that i can not find any code that shows how to implement the Tree-structure as it is used in the regular package explorer.
Thank you for your help,
