Java Swing: how can I resize a single row in a Grid layout and allow it to be dynamically resized only horizontally and not vertically?

Hi everyone, I have a JFrame in which there are three components.

  • Menu
  • Tab bar
  • panel with several buttons

My initial goal was to create a design such as: enter image description here

when the user resizes the application, everything will be resized. So I thought, maybe if I used a simple grid layout, my problem would be solved, so I decided to do the following:

  • Some panels will be embedded in the tabbed panels, and these panels will follow the layout of the grid.

  • The panel below will follow the grid pattern.

  • JFrame will also follow the layout of the grid.

Results:
