I am currently programming a dialog. The special thing about it: the panel-hierarchies and elements are defined in excel and the resulting java-structure is generated and only has to be copied into the main program.
The demo shows the first development steps. In order to get an overview the elements are moved explosively in the z direction.
You can clearly see how the hierarchies of the panels are structured. It also contains a function to output multiline texts.
The excel file: cube3_input.xlsx
