我有以下代码:

ActionListener listenerComboVehicle = new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        comboVehicle.removeActionListener(listenerComboVehicle);
        frameCrewSelection.removeAll();
        frameCrewSelection.add(formCrewSelectionForm(SpaceObjectArray.findMannedByName(comboVehicle.getSelectedItem().toString()))); //Create some controls (Jcombobox comboVehicle included) and assign listeners to them.
        formComboCrews(); //Modify JCombobox controls content
    }
};

我的应用程序挂在以下代码上EventDispatchThread.java

void pumpEventsForFilter(int id, Conditional cond, EventFilter filter) {
    addEventFilter(filter);
    while (doDispatch && cond.evaluate()) {
        if (isInterrupted() || !pumpOneEventForFilters(id)) {
            doDispatch = false;
        }
    }
    removeEventFilter(filter);
}

while 循环是无限的,它会挂起我的应用程序。当.removeAll()不存在时,应用程序不会挂起,但我会在旧控件上获得新控件。我通过布置一个框架并再次创建它找到了一种解决方法,但它看起来很讨厌。如果需要,将提供其他代码。请帮忙。

从评论中移出以获得更好的视图:

frameCrewSelection.getContentPane().removeAll(); frameCrewSelection.setContentPane(formCrewSelectionForm(SpaceObjectArray.findMan‌​nedByName(comboVehicle.getSelectedItem().toString())));

让它工作。
