Терпения не хватило работать с GridBagLayout, но смысл примерно тот же, может у Java задача проще, ибо приходится меньше изменять размеры. 1. В Qt все отступы уже продуманы, не надо работать с Insets 2. В Qt сложную GUI сетку можно сделать проще чем в SWING Теперь диагноз: в целом после растягиваний Qt программки остаются приятные ощущения, усталости не наблюдается. При работе с SWING программой весь экран содрагается в очень частой перерисовке (перерисовывается не только окно программы, но и весь рабочий стол и его приложения), остается ощущение неполноценности и ущербности, хочется быстрей бежать от такоо приложения.
