Java JFrame removeall挂起应用程序 [英] Java JFrame removeall hangs an application

问题描述

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 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，它挂起了我的应用程序。当 .removeAll（）不存在时，应用程序不会挂起，但我获得了旧控件的新控件。我找到一个解决方法，通过处置一个框架，并再次创建，但它看起来很讨厌。如果需要，将提供附加代码。请帮助。

The while loop is infinite and it hangs my application. When .removeAll() is absent, the application doesn't hang but I get new controls over old controls. I've found a workaround by disposing a frame and creating it again but it looks nasty. Additional code will be provided if needed. Please help.

推荐答案

从评论中移除更好的视图：

Moved from comments for better view:

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

。
