导读：我正在寻找在Swing上下文中使用F XML的 JavaFX 2的一点帮助.我使用Scene Builder构建了一个场景(版本：2.0-b10,变更集：48fc80a12d33),我试图在Java 1.7下将其加载到Swing中的JFrame上的JFXPanel中.当我这样做时,我在第16行得到一个无效属性错误.这是第16行

JavaFX 2的一点帮助.我使用Scene Builder构建了一个场景(版本：2.0-b10,变更集：48fc80a12d33),我试图在Java 1.7下将其加载到Swing中的JFrame上的JFXPanel中.当我这样做时,我在第16行得到一个无效属性错误.这是第16行：< Label style =“ - fx-font-weight：bold;” text =“存储概述主页”VBox.vgrow =“从不”>

我用来尝试显示场景图的代码是： Platform.setImplicitExit(false);
Platform.runLater(new Runnable() {
@Override
public void run() {
Parent root;
try {
root = FXMLLoader.load(getClass().getResource("MyPanel.fxml"));
Scene scene = new Scene(root);
swingPanel.setScene(scene);
} catch (Exception ex){
//Log an error here...
}
}
});
我得到的错误是： Invalid property. /C:/HelpSys/space/trunk/gui/classes/com/helpsystems/space/gui/csi/MyPanel.fxml:16 at javafx.fxml.FXMLLoader$PropertyElement.<init>(FXMLLoader.java:1154) at javafx.fxml.FXMLLoader.createElement(FXMLLoader.java:2338) at javafx.fxml.FXMLLoader.processStartElement(FXMLLoader.java:2311) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2131) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2028) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2744) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2723) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2709) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2696) at javafx.fxml.FXMLLoader.load(FXMLLoader.java:2685) at com.helpsystems.space.gui.csi.CSIWizzard$1.run(CSIWizzard.java:182) at com.sun.javafx.application.PlatformImpl$4$1.run(PlatformImpl.java:179) at com.sun.javafx.application.PlatformImpl$4$1.run(PlatformImpl.java:176) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl$4.run(PlatformImpl.java:176) at com.sun.glass.ui.win.WinApplication._runLoop(Native Method) at com.sun.glass.ui.win.WinApplication.access$100(WinApplication.java:29) at com.sun.glass.ui.win.WinApplication$3$1.run(WinApplication.java:73) at java.lang.Thread.run(Unknown Source) 解决方法
padding属性不是JavaFX 2.2中Label中的有效属性.在JavaFX 8中,Label继承自Region(通过Control),因此继承了padding属性.所以我怀疑SceneBuilder正在查看JavaFX 8以确定属性.
在JavaFX 2.2中有一个labelPadding属性,可以从CSS设置,所以使用 <Label style="-fx-font-weight: bold; -fx-label-padding: 6 0 18 6;" text="Storage Overview Home"
VBox.vgrow="NEVER">
</Label>
