如何在 JFrames 中使用 setVisible?
在我的程序中,我有两个 JFrame
实例.当我单击 next
按钮时,我想显示下一帧并隐藏当前帧.所以我使用 this.setVisible(false)
和 new Next().setVisible(true)
.但是在 Next
窗口中,如果我单击 back
按钮,我想将前一帧设置为再次可见并且下一帧必须结束(这意味着它必须退出).
In my program I have two JFrame
instances. When I click next
button I want to show next frame and hide current frame. So I use this.setVisible(false)
and new Next().setVisible(true)
. But in Next
window if I click back
button I want to set previous frame to be visible again and next frame must be ended (which means it must be exited).
有什么特殊的方法可以做到这一点吗?我该怎么做?
Is there any special method(s) to do this? How can I do it?
推荐答案
考虑使用 CardLayout 而不是寻找有多少 JFrames 有.那么..
Consider using CardLayout instead of hunting for how many JFrames there are. Then..
- 只需要一个 JFrame
- 任何下一步/后退操作都只会在卡片之间切换
此论坛中有很多示例 - 例如如图所示这里.
There are lots of examples in this forum - e.g. as shown here.
