In general, both methods work, but only as soon as the ScrollPane's skin property has been set. In my case, skin was still null after

问题 I need to write a desktop app and its been a while since I started used Swing so will have a learning curve with either technology. Are there any advantages in doing my app using JavaFX 2? 回答1: 4 Years back I was having the same question and came to the conclusion that I would be best of using Swing since a lot of third party libraries were still written for Swing in those days. Also 1.0 releases from Sun were usually a bit rough around the edges (I burned myself on JSF 1.0 and JPA 1.0 :-).

问题 in c++ or c programming language, we know to change the cordinate we use gotoxy(x,y) and we can use looping and sleep to change the cordinate and making animation. like this; for(x = 20; x < 25; x++){ gotoxy(x,20); cout << "*" } but my queston is how about in JAVAFX 2.0 programming? i'm using netbeans 7.2. thanks for your any help. 回答1: Have look at using a Timeline Animation.

问题 The ability to wrap a swing component in a javaFX application seems to have vanished from javaFX 2: javafx.ext.swing.SwingComponent is not there any more in javaFX 2 beta API. Is there still a way to do this in the new API? 回答1: SwingNode class is used to embed a Swing content into a JavaFX application. Here is the link. 回答2: There is 3rd-party support library, see http://rkennke.wordpress.com/2011/11/16/swing-in-javafx-demo/ 回答3: According to this issue on the FX 2.0 JIRA they aren't

问题 I'm having a hard time figuring out how to make a transparent background for an application window in javafx. scene.setFill(null) seems to only work with stage.initStyle(StageStyle.TRANSPARENT) . Doc for setFill says Both a null value meaning paint no background and a Paint with transparency are supported, but what is painted behind it will depend on the platform. but that doesn't make sense to me. It works (on windows 8) only with StageStyle.TRANSPARENT which removes the exit button and such
