JavaFX 2模态窗口 [英] JavaFX 2 modal window

问题描述

我正在尝试使用JavaFX 2创建一个登录窗口并停止执行，直到用户没有登录。我想要如下所示：

I'm trying to create a login window with JavaFX 2 and stop execution until the user has not logged. I want something like the below:

showLoginDialog();
showMainWindow();

showLoginDialog 负责创建一个新阶段并将其父级设置为主窗口。它将阶段设置为模态，我尝试了 WINDOW_MODAL 和 APPLICATION_MODAL ，但是一旦显示登录窗口，也会调用 showMainWindow（）行。

showLoginDialog is responsible for creating a new stage and set its parent to be the main window. It sets the stage to be modal, I tried both WINDOW_MODAL and APPLICATION_MODAL, but as soon as the login window is showed, the showMainWindow() line is called as well.

是否可以停止代码运行直到<$调用登录阶段的c $ c> close（），或类似的东西？是否有任何教程展示如何实现这一目标？

Is it possible to stop code running until the close() of the login stage is called, or something similar? Are there any tutorials showing how this can be achieved?

推荐答案

正如Uluk所说，有一个JIRA问题。该问题已在JavaFX的2.2版测试版中关闭并修复。
如果需要停止执行程序，只需使用以下代码：

As Uluk said there is a JIRA issue. The issue has been closed and fixed in version 2.2 beta of JavaFX. Just use the following code if execution of the program needs to be stopped:

modalWindowStage.showAndWait();

其中 modalWindowStage 是用于展示的阶段消息框。
如果执行需要继续，只需使用通常的'show（）'方法。

where modalWindowStage is the stage used for showing the messagebox. If the execution needs to continue, just use the usual 'show()' method.
