标题[问题]想使用Button 改 Frame title 的错误
时间Sun Jun 22 16:36:08 2008
我在Button设了event
想用它来改Frame的title
event的内容如下:
public void actionPerformed(ActionEvent e) {
System.out.println(e.getActionCommand());
f.setTitle(e.getActionCommand());
}
结果就出现:
at java.awt.Button.processActionEvent(Unknown Source)
at java.awt.Button.processEvent(Unknown Source)
at java.awt.Component.dispatchEventImpl(Unknown Source)
at java.awt.Component.dispatchEvent(Unknown Source)
at java.awt.EventQueue.dispatchEvent(Unknown Source)
at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source)
at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)
at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.pumpEvents(Unknown Source)
at java.awt.EventDispatchThread.run(Unknown Source)
错误
刚学java没多久
实在搞不清楚错误原因
希望有人可以教我解决办法
或是告诉我错误原因
谢谢!!!
