I am trying to organising three windows. One of them is a header windows which should be always in the top of the screen, the second one is a windows which has a tree and it has to appear on the left but under the header window, so the free space has to be for the main window.
In the attached A picture I have represented the structure that I would like to have. Intead of that I get the result of picture B using these “Dock Positions”: North in Header, West in Tree and Floating in the main window.
Is it possible to get the structure A?
Thanks a lots.
