单击JButton后关闭jFrame [英] Closing jFrame after clicking JButton

问题描述

我在NetBeans中设计了两个JFrame。

I have designed two JFrames in NetBeans.

当我点击规则按钮（即放在JFrame1上）时，它会打开第二个JFrame（但是JFrame2会打开）在JFrame1的窗口，这是我不想要的）。
在第二个JFrame中有一个关闭按钮。但是当我点击这个按钮时，我想要打开JFrame1并且它也正常工作，但JFrame2实际上没有关闭，而JFrame1正在JFrame2上出现。

When I click the "rules" button (i.e placed on JFrame1) then it opens a second JFrame (but JFrame2 opens over JFrame1's window, that's what I dont want). In the second JFrame there is a "close" button. But when I click this button, I want JFrame1 to be opened and it is working too, but JFrame2 is actually not closed and JFrame1 is appearing over JFrame2.

简而言之主要形式是JFrame1。当我点击JFrame1中的规则按钮时，它会在JFrame1上打开JFrame2，而在JFrame2中，当点击主窗体（即JFrame1）时，会有一个关闭按钮，但它会在JFrame2上启动。

In short the main form is JFrame1. When I click the "rules" button from JFrame1 it opens JFrame2 over JFrame1, and in JFrame2 there is a "close" button when it gets clicked the main form (i.e JFrame1) is lauched but it is launched over JFrame2.

场景是JFframe1 - > JFrame2 - > JFrame1

The scenerio is JFframe1 -> JFrame2 -> JFrame1

现在我的问题是点击规则按钮后，JFrame1应该关闭，JFrame2显示在屏幕上，反之亦然。

Now my question is after clicking the "rules" button, JFrame1 should be closed and JFrame2 displayed on the screen and vice versa.

推荐答案

假设你的按钮有一个actionListener，点击规则按钮后放入：

Assuming your button has an actionListener, after clicking the "rules button" put in:

      JFrame1.dispose();  //Remove JFrame 1
      JFrame2.setVisible(true) //Show other frame

然后尊重他们反对的反应

And then reverese them for the opposite reaction
