问题 A relative Java newbie question. I'm trying set a TableRow 's background colour based on whether or not it's selected and/or whether or not a boolean value in the data model is true. I've found ways of doing each but not both together in the same setRowFactory . What I would like to end up with is this (albeit with horrible colours for example purposes only!): How would I go about achieving that? This is what I found wrt changing row colour based on selection. It's adapted from user James_D's

问题 I'm having trouble with centering an ImageView node within the following Browser object. I have provided a snippet of the code below.

问题 I have some kind of drawpane, where the user can draw different kinds of Shapes, like Pathes, Rectangles, Texts, etc. Now I´d like to persist the DrawState, so that I can recreate it at any time. I just tried it with xstream, but like usual I get a whole lot of dependencies within these Shapes when persisting it in XML. After some research I found this Thread here: Serialize JavaFX components I liked the idea of jewelsea using the SceneBuilder API to serialize my shapes, since they are all

问题 I have encountered some problem when trying to select single row from table view in JavaFX. Here is how I populate my table with data from database: public void populateCategoryTable() { data = FXCollections.observableArrayList(); try { db.getConnection(); String sql = "SELECT * FROM sm_category"; ResultSet rs = null; // Call readRequest to get the result rs = db.readRequest(sql); while (rs.next()) { ObservableList<String> row = FXCollections.observableArrayList(); //All the rows are added

问题 I've been doing a lot of voxel terrain generation with JavaFX 3D. For some reason, whenever I generate a landscape, the right side of the landscape will always have these weird black lines. I've tried changing the PerspectiveCamera 's near and far clip values, but they seem to have no effect. In case you need it, my near clip value is set to 0.1 and my far clip value is set to 100000.0 . Here is a picture of my program, as you can see, there are clear visual glitches present mainly on the

问题 Does IBM's java 7 bundle Java FX 2? I have JDK Version 7 Release 1 for Linux (32 bit) and it doesn't seem to contain it. If it doesn't, can I still use it, and what do I need to do for that? Thanks 回答1: No, IBM Java 7 does not include JavaFX 2. The Oracle distributions of Java 7 and 8 are the only supported Java runtimes that include JavaFX that I am aware of at this time. JavaFX 2 is mostly closed source, so you can't really port it to any other runtimes. JavaFX 8 is completely open source,
