我有一个方法窗口Frame (), 它扩展了 Jframe, 并为我的程序设置了 GUI, 在主方法中的例子就是 MyFrame 。 默认情况下它设置了 AlwaysOnTop( false) 。 但是在窗口Frame () 方法中, 我有一个 JcheckBox 方法, 我想用它来将上面的属性变真或变假。 我的问题是, 我怎样才能对已经存在的 MyFrame 窗口 GUI 进行这样的操作?
我拥有听众和所有东西, 但我只是不知道如何在主方法中提及我的Frame窗口, 因为 JcheckBox 和听众在窗口Frame () 方法中, 但这个例子当然是他们外部的。 我尝试了使用这个。 setAlwaysOnTop( true), 并且只是设置了“ 永远OnTop( true) ” ( true), 但当然这行不通 。
补充信息:所有东西都包裹在同一个主类中,我只需要一个窗口的例子。
