JavaFX FXMLLoader无效属性
JavaFX FXMLLoader无效属性
提问于 2014-01-21 16:03:14
我希望在Swing上下文中使用JavaFX 2来获得一些帮助。我用场景生成器(版本:2.0b10，Changeset: 48fc80a12d33)构建了一个场景，并试图简单地将其加载到Java1.7下的Swing JFXPanel上。当我这样做时，我会在第16行得到一个无效的属性错误。
以下是整个场景：

padding属性不是Label中JavaFX 2.2中的有效属性。在JavaFX 8中，Label继承了Region (通过Control)，因此继承了padding属性。因此，我怀疑SceneBuilder正在查看JavaFX 8以确定属性。
在CSS 2.2中有一个可以从JavaFX设置的labelPadding属性，所以请使用
<Label style="-fx-font-weight: bold; -fx-label-padding: 6 0 18 6;" text="Storage Overview Home"
VBox.vgrow="NEVER">
