如何清除/重置JFrame [英] How to clear/ reset a JFrame

问题描述

我和我的朋友决定开展一个在3个屏幕之间循环的纸牌游戏（ Player1HandScreen，Player2HandScreen和FightScreen ）。

Me and my friend have decided to work on a card game which cycles between 3 screens (Player1HandScreen, Player2HandScreen and FightScreen).

一旦Player1从 Player1HandScreen 中选择了他们的卡， Player1HandScreen 导致 Player2HandScreen 其中Player2也是如此。然后 Player2HandScreen 导致 FightScreen 比较两张牌并且一名玩家被宣布为该轮的获胜者。

Once Player1 has chosen their card from Player1HandScreen, Player1HandScreen leads to Player2HandScreen where Player2 does the same. then Player2HandScreen leads to FightScreen where the two cards are compared and one player is declared the winner of that round.

我们遇到的问题是，一旦结束，我们要清除 Player1HandScreen 以及 Player2HandScreen 刷新我们的参数后，我们无法成功更新GUI。

The problem we are having is that once the round ends we want to clear Player1HandScreen as well as the Player2HandScreen once refreshing our parameters we are having trouble updating the GUI successfully.

我们已尝试使用 removeAll（），但我们无法将其转换为 repaint（）或 validate（）。

We have have tried to use removeAll(), but we can't get it to repaint() or validate().

我们还调查了 super.paintComponents（g）和 updateUI（）但两者都给我们留下了希望和梦想。

We have also looked into super.paintComponents(g) and updateUI() but both have left us with crushed hopes and dreams.

推荐答案

如果你删除来自Container的任何JComponent（只有一次），需要告诉Container，

if you remove any JComponent(s) from Container (only once on the end), is needed tell to Container for,

removeAll()//or remove(JComponent)
revalidate();
repaint();
