如何在Swing中递归禁用组件? [英] How do I recursively disable my components in Swing?

问题描述

如何递归禁用JPanel中的所有组件?

How do I recursively disable all of my components in a JPanel?

推荐答案

void setEnabled(Component component, boolean enabled) {
    component.setEnabled(enabled);
    if (component instanceof Container) {
        for (Component child : ((Container) component).getComponents()) {
            setEnabled(child, enabled);
        }
    }
}

请注意，除非您在其他位置跟踪它，否则每个组件的先前启用/禁用状态都会丢失.

Be aware that the previous enabled/disabled state of each component will be lost, unless you keep track of it somewhere else.
