@mathuo Thanks for this experiment! It looks very promising, especially preferredSize. However panels rarely have square shaped content: the preferred width most of the time it does not equal with the preferred height.

Some examples:

• List panel designed for displaying as a narrow vertical bar by default. It has a preferred width of 420px, but no preferred height if I put it above/below a panel (especially not the 420px specified for width).
• Search box panel: it has a text field for searching. It has a preferred height of 120px and a preferred width of 450px.

This is really important to address, while min/max are a good start, day to day using the dockview it is important to be able to set flexible sizes to each panel
