问题描述
这是我的Start-Methode。首先,我创建一个舞台,并设置标题和场景。如果有人想关闭window-close-btn [X]上的窗口,我想创建一个对话框。我以为我会用setOnCloseRequest() - 函数捕获这个事件。但我仍然可以关闭我在运行时打开的所有阶段。
This is my Start-Methode. First i create a stage and set a title and a scene. And i wanna create a dialog if someone wants to close the window on the window-close-btn [X]. i thought i will catch this event with the setOnCloseRequest()-function. But i still can close all stages i open while runtime.
@Override
public void start(final Stage primaryStage) throws Exception {
primaryStage.setTitle("NetControl");
primaryStage.setScene(
createScene(loadMainPane())
);
primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
@Override
public void handle(final WindowEvent event) {
//Stage init
final Stage dialog = new Stage();
dialog.initModality(Modality.APPLICATION_MODAL);
// Frage - Label
Label label = new Label("Do you really want to quit?");
// Antwort-Button JA
Button okBtn = new Button("Yes");
okBtn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
dialog.close();
}
});
// Antwort-Button NEIN
Button cancelBtn = new Button("No");
cancelBtn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
primaryStage.show();
dialog.close();
}
});
}
});
primaryStage.show();
}
private Pane loadMainPane() throws IOException {
FXMLLoader loader = new FXMLLoader();
Pane mainPane = (Pane) loader.load(
getClass().getResourceAsStream(ContentManager.DEFAULT_SCREEN_FXML)
);
MainController mainController = loader.getController();
ContentManager.setCurrentController(mainController);
ContentManager.loadContent(ContentManager.START_SCREEN_FXML);
return mainPane;
}
private Scene createScene(Pane mainPane) {
Scene scene = new Scene(mainPane);
setUserAgentStylesheet(STYLESHEET_MODENA);
return scene;
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Application.launch(args);
}
是否还有其他功能可以捕获窗口事件?
或者在primaryStage上运行CloseRequest是不合逻辑的,我用平台读了一些东西(但我不知道是否有必要解决我的问题)?
Are there any other functions to catch the window-events?or isnt it logical to run the CloseRequest on the primaryStage, i read something with platforms (but i dont know if it necessary for my problem)?
推荐答案
在 onCloseRequest
处理程序中,调用 event.consume();
。
In the onCloseRequest
handler, call event.consume();
.
这将阻止初级阶段结束。
That will prevent the primary stage from closing.
从取消按钮的处理程序中删除 primaryStage.show();
调用并添加对<$ c的调用$ c> primaryStage.hide(); 在OK按钮的处理程序中。
Remove the primaryStage.show();
call from the cancel button's handler and add a call to primaryStage.hide();
in the OK button's handler.
