问题 Is there a way to know if a scroll bar is present on a table view? (Other than what I did in my code below) My goal is to position 2 arrow images (to close/open a side panel) on the right side of a table (over the table.). But I don't want to put them over the scroll bar. The table content is a result of a search, so sometime the scroll bar is visible and other time it is not. If there is not enough items. I want the position of my arrows to change every time the tableview items change. I

问题 Trying to figure out on how can i disable the reordering of table columns in javafx 2? 回答1: Here's the solution: tblView.getColumns().addListener(new ListChangeListener() { @Override public void onChanged(Change change) { change.next(); if(change.wasReplaced()) { tblView.getColumns().clear(); tblView.getColumns().addAll(column1,column2...); } } }); 回答2: After much waste of time, I've found the following, very simple, solution: TableHeaderRow header = (TableHeaderRow) myTableView.lookup(

问题 I have a ScrollPane in my scene and would like to add a series of Nodes to it. The exact amount must be dynamic. I've been testing the concept with Label nodes and can successfully add as many Labels as I want to the content of the ScrollPane (currently a VBox). My problem is figuring out how to allow the user to scroll normally through the ScrollPane full of Nodes. The content matches pace with the scrollbar; that is, when I scroll down, the content moves down. I scroll up, the content

问题 The TableView class of JavaFX 2.2 has a generic type S , I am wondering how one can set this from FXML? 回答1: The same happens to a ListView or ComboBox. But I think that in the FXML file you are defining the controls and you are defining a generic ListView or a ComboBox or TableView or whatever. No matter what they are going to show. So to me it makes more sense to set the generic type in the JavaFX controller class, instead of in the FXML file. Hope it helps. 回答2: FXML is dynamically loaded

问题 I have looked around quite a bit and cannot find the solution. I am adding a separator in SceneBuilder . This is easy. Now I want this separator to be a solid line. This I am having issues with.

问题 I'm just getting into using fxml and it seems like a really cool idea, except for the fact that I'm having a tough time getting it to work. Supposedly I'm able to lay out my GUI using a nice markup language, and I can style the elements via CSS. So I have a label on my GUI, and I would like there to be a solid black border around it, with width=1. Seems like this should be straightforward -- adapting examples I see here and there in tutorials, etc., I do the following: <Label text="sample

问题 How do I set tab width of JavaFX TextArea ? When I use tabulation (tab key) in TextArea, the width of the tabulation is wide. I want to control the width, i.e., use 4 spaces. In the documentation I could not find a method to do this. I tried this code (where taInput is a TextArea), but it is not working as it should: taInput.setOnKeyPressed(new EventHandler<KeyEvent>() { @Override public void handle(KeyEvent e) { if (e.getCode() == KeyCode.TAB) { // TAB SPACES StringBuilder sb = new
