What is the best way to add row components in ListBox? Say I have an empty ListBox at the beginning, and my program logic can generate the number of new rows to be added. The getNumRows() of ListBoxModel will be initialized to 0. I wanna update the number of rows, and then use updateContent() to create new row components. However, I couldn’t figure out how to update row number. Any help will be appreicated sincerely.
I haven’t used this ListBox feature so can’t ensure it works or if I’m talking nonsense, but why not generate a new data model (copying into it what you already had) with the new stuff you want. Then set it using setModel(). Take a look at the documentation
