JavaFX阶段模式 [英] JavaFX Stage Modality

问题描述

我试图制作一个通过舞台打开的Modal窗口.这是代码:

I am trying to make a Modal window, opened through a Stage. This is the code:

Stage stage = new Stage();                               
Parent root = fxmlLoader.load();
stage.setScene(new Scene(root));
stage.setTitle("Stuff");
stage.initModality(Modality.WINDOW_MODAL);
stage.show();

但是，按我的方式，单击下面的窗口并没有实际成功. 我有做错什么吗?

But with no actual success, as I am able though, to click the underlying windows. Is there anything that I am doing wrong?

我在Oracle站点上查阅了早期文档，但是可以找到解决方案，因为显示的窗口的行为与模态窗口"的预期行为并不太相像. 我在该项目上使用的JDK是1.8.0_40

I checked earlier the documentation at Oracle's site, but could find a solution, as the displayed window's behavior wasn't any close to what its expected from a Modal Window. The JDK I am using on this project is 1.8.0_40

根据ItachiUchiha的要求，句柄中的代码

EDIT 2: The code within the handle, as requested by ItachiUchiha

Boolean confirmacion = MessageUtil.ventanaConfirmacion(RecursosUtil.creaTextoProperties("confNoRealizar"));

if (confirmacion) {
    try {
        TbInspeccion inspeccionSeleccionada = (TbInspeccion) getTableRow().getItem();

        URL location = cargaURLFXML(OBSERVACIONESFXML);
        FXMLLoader fxmlLoader = cargaFXML(location);

        stage = new Stage();
        Parent root = fxmlLoader.load();
        stage.setScene(new Scene(root));
        stage.setTitle("Observaciones");

        ObservacionesController controller = (ObservacionesController) fxmlLoader.getController();
        controller.setStage(stage);
        controller.setInspeccion(inspeccionSeleccionada);
        controller.setProvider(provider);
        controller.setTablaPrincipal(tablaPrincipal);

        stage.initModality(Modality.APPLICATION_MODAL);
        stage.show();
    } catch (IOException ex) {
        Exceptions.printStackTrace(ex);
    }
}

感谢您的时间和帮助.

推荐答案

替换

stage.initModality(Modality.WINDOW_MODAL);

与

stage.initModality(Modality.APPLICATION_MODAL);

前者阻止如下:

定义一个模式窗口，该窗口阻止事件传递给它 整个所有者窗口层次结构.

Defines a modal window that block events from being delivered to its entire owner window hierarchy.

而后者:

定义一个模式窗口，该窗口阻止事件传递给任何事件 其他应用程序窗口.

Defines a modal window that blocks events from being delivered to any other application window.

根据您为什么要实现上述行为，您可能需要使用

Depending on why you want to achieve the aforementioned behaviour you might want to use JavaFX 8 Dialog available from JDK 8 Update 40
