创建JavaFX对话框 [英] Creating a JavaFX Dialog Box

问题描述

我编码一个javafx程序，我需要创建和使用我自己的基于Stage（Javafx.Stage）对话框来显示消息和确认。我现在写了所有必要的代码，但是我有一个问题：

对话框必须停止执行其余的代码，直到响应如是或否或重试。当我使用我的对话框，如DialogBox.ShowMessage，一个阶段出现与消息和按钮。但是，如你所想，代码的其余部分继续执行。我该怎么办？当我创建舞台时，它必须停止其他线程或其所依赖的线程。我通过互联网和这里搜索，但我找不到确切的解决方案。一个想法是使用javafx.event.EventDispatcher或javafx.event.EventDispatchChain，但我无法弄清楚如何使用它们。另一个想法是使用java.awt.EventQueue。这里有一些可以帮助的事情：我可以控制舞台表演和隐藏事件，并显示或隐藏事件处理程序。我认为某种线程队列可以在其中一个spesific部分中使用。

我希望我能够充分了解情况。简单来说，ı需要管理线程，而使用另一个阶段，我自己的代码。

谢谢。

解决方案

关于执行暂停有一个Jira问题 http： //javafx-jira.kenai.com/browse/RT-19783 。

作为解决方法，我不知道如何使用EventDispatcher和EventDispatchChain来克服此问题，但您可以发送 EventHandler 作为参数。例如，

  public static void ShowMessage（final EventHandler< ActionEvent> okAction，final EventHandler< ActionEvent> cancelAction）{
 
 //定义并添加按钮到视图并显示消息
 
 btnOk.setOnAction（new EventHandler< ActionEvent>（）{
 public void handle（ActionEvent event） {
 okAction.handle（null）; 
} 
}）; 
 
 btnCancel.setOnAction（new EventHandler< ActionEvent>（）{
 public void handle（ActionEvent event）{
 cancelAction.handle（null）; 
} 
}）; 
} 
  

并将其用作

pre> DialogBox.ShowMessage（
new EventHandler< ActionEvent>（）{
@Override public void handle（ActionEvent arg0）{
// Do
}，
新的EventHandler< ActionEvent>（）{
@Override public void handle（ActionEvent arg0）{
//在取消 click $。
}）;


我同意这是一种蜿蜒的方式。

I am coding a javafx program and i need to create and use my own Stage based (Javafx.Stage) dialog box for showing messages and confirmations. I have written all the necessary code by now but i have a problem:

A dialog box must stop execution of rest of the code until a respond is given like "yes" or "no" or "retry". When i use my dialog box like "DialogBox.ShowMessage", a stage appears with message and buttons. But, as you may think, the rest of the code continues to execute. How can i get around this? When i create the stage, it must stop the other threads or the thread that it depends on. I have searched through internet and here, but i can not find exact solution. One idea is using "javafx.event.EventDispatcher" or "javafx.event.EventDispatchChain" but i couldn't figure out how to use them. And another idea is using "java.awt.EventQueue". And here is somthing that can help: I have a control of stage show and hide events and showing or hiding eventhandlers. I think som sort of thread queue can be used in one of these spesific sections.

I hope i clarified the situation enough. Briefly, ı need to manage threads while using another stage with my own code.

Thank you.

解决方案

About execution suspending there is a Jira issue for it http://javafx-jira.kenai.com/browse/RT-19783.
As a workaround, I have no idea how to use EventDispatcher and EventDispatchChain to overcome this problem but you can send the EventHandlers as parameter. For instance,

public static void ShowMessage(final EventHandler<ActionEvent> okAction, final EventHandler<ActionEvent> cancelAction){

   // Define and add buttons to the "view" and show message

   btnOk.setOnAction(new EventHandler<ActionEvent>() {
        public void handle(ActionEvent event) {
        okAction.handle(null);
        }
    });

   btnCancel.setOnAction(new EventHandler<ActionEvent>() {
        public void handle(ActionEvent event) {
        cancelAction.handle(null);
        }
    });
}

and use it as,

DialogBox.ShowMessage(
 new EventHandler<ActionEvent>() {
      @Override public void handle(ActionEvent arg0) {
        // Do stuff when "ok" clicked. 
},
 new EventHandler<ActionEvent>() {
      @Override public void handle(ActionEvent arg0) {
        // Do stuff when "cancel" clicked. 
});

I agree with this is a kind of "winding" way however.
