在另一个JFrame的按钮单击上放置一个JFrame [英] Dispose a JFrame on button click from another JFrame

问题描述

许多人可能知道，我是一名完全的Java新手。我已经尝试过对此进行研究（通过阅读StackOverflow上的其他文章，谷歌搜索，并问一个不太喜欢Java新手的朋友），但我不知道。答案可能是明确而容易的，但我对此视而不见。我试图从另一个框架中处置 JFrame 。

As many probably know, I am a complete Java newbie. I have already attempted to research this (by reading other posts on StackOverflow, Googling and asking a friend who is less of a java newbie) but I can't figure it out. The answer is probably clear and easy but I am blind to it. I am attempting to dispose a JFrame from a different frame.

我的应用程序应按以下方式工作：

My application is supposed to work as follows:

• 框架X有一个按钮，当按下时：产生框架Y


• 框架Y有一个按钮，按下时：产生框架Z


• 框架Z上有一个按钮，按下时：在处理框架Y及其本身之前，从框架Y执行方法。

获取Z帧以处置Y帧是我大多数问题所在。
任何帮助将不胜感激。理想情况下，以这样的方式表达帮助，即使是婴儿也可以理解（因为这是我对Java的理解水平）。

Getting frame Z to dispose frame Y is where most of my issues are. Any help is greatly appreciated. Ideally help will be phrased in such a way that even a baby could understand (because that is my level of Java comprehension).

我知道很多人会认为这是重复的此问题或其他问题。我认为这不是重复的问题，因为我已经阅读了这两个书，并且不了解如何解决自己的问题。

I know many will think this is a duplicate question of either this question or this other question. I believe it is not a duplicate question because I have read both and have not understood how to resolve my own problem.

推荐答案

• 按下框架Z时有一个按钮：在放置框架Y及其本身之前，从框架Y执行方法。

框架Y和框架Z应该是模式对话框（至少Z应该是，可能也是Y）。

Frame Y and frame Z should be modal dialogs (at least Z should be, probably also Y).

当对话框Y打开对话框Z（我们将其称为 dialogZ ）时，代码应如下所示：

When dialog Y goes to open dialog Z (we'll call it dialogZ) the code should go something like this:

DialogZ dialogZ = new DialogZ(..);
dialogZ.setVisible(true);
this.setVisible(false); // at this point, dialogZ will have been closed

请参见如何在对话框中使用模态以获取详细信息和示例代码。

See How to Use Modality in Dialogs for details and example code.

（框架Z）…执行方法，从框架Y

框架Y和框架Z应该 不 扩展任何类。相反，它们应该是根据需要使用的实例变量。

Frame Y and Frame Z should probably not extend any class. Instead they should be instance variables that are used as needed.
