Вот, чуток оптимизировал код, ну тоисть уже с чем-то разобрался, но все равно не срабатывает JScrollPane. В данном случае она нужна и не появляется, а если поставить, чтоб всегда стояла, то все равно не работает. Переделал левую колонку со SpringLayout -интуитивно понятней.
Как мне убрать отступ между trenn_panel2 и scr_panel?
И еще, скажите пожалуйста, если вручную собирать интерфейс - нужно всегда указывать предпочтительные размеры всего? Или например я в панель добавил 50 меток, и они заняли там все пространство.
Код.
