JavaFX/Controlsfx - 如何监控 PropertySheet 中的项目变化?

JavaFX/Controlsfx - How to monitor item change in a PropertySheet?

有没有方便的方法来监控 属性 工作表项状态?像文本字段获得焦点、布尔状态更改等。

我看过 javadoc,没找到。

这里还有一个issue,不过解法好像让小编知道了一个属性的变化。

我要的恰恰相反,监督小编

有人可以帮忙吗?

来自 PropertySheet:

/**
 * Sets a new editor factory used by the PropertySheet to determine which
 * {@link PropertyEditor} to use for a given {@link Item}.
 * @param factory 
 */
public final void setPropertyEditorFactory( Callback<Item, PropertyEditor<?>> factory ) {
    propertyEditorFactory.set( factory == null? new DefaultPropertyEditorFactory(): factory );
}

如果您创建 PropertyEditor 的回调,您可以向编辑器添加侦听器。

例如:

    SimpleObjectProperty<Callback<PropertySheet.Item, PropertyEditor<?>>> propertyEditorFactory = new SimpleObjectProperty<>(this, "propertyEditor", new DefaultPropertyEditorFactory());
    projectSheet.setPropertyEditorFactory(getItemPropertyEditorCallback(propertyEditorFactory));



private Callback<PropertySheet.Item, PropertyEditor<?>> getItemPropertyEditorCallback(SimpleObjectProperty<Callback<PropertySheet.Item, PropertyEditor<?>>> propertyEditorFactory) {
    return param -> {
        PropertyEditor<?> editor = propertyEditorFactory.get().call(param);

        //Add listeners to editor
        editor.getEditor().focusedProperty().addListener((observable, oldValue, newValue) -> System.out.println(newValue));

        return editor;
    };
}
