I have some problem with loading a fxml.
What I want to do it that:
I have 4 fxml files: main.fxml, head.fxml, body.fxml and new.fxml
Main includes head and body (i.e. I included (NOT imported) head and body inside main).
When I click a button in head, I want to load new.fxml and cover the body.fxml
I don't want to replace body.fxml with new.fxml. I just want to cover it.
Is there a possible way to achieve it?

I have a FXML document containing the visual basis of my JavaFX project and I want to make an own Topbar (where the X, minumum/maximum, etc... is) by using a Pane. But my program will have multiply pages (scenes) and to keep the code clean, I wanted to make the Custom-Topbar as a separate class (an component object kinda). I just don't know how I should implement this class into the FXML basis I use (I am using Scene Builder).
Option 1
If the toolbar is always there you can have a main fxml file with the toolbar and a container.
Then load content from other fxmls and place that content in the container. To switch pages switch the content of the container (and not the scene).
Option 2
Create an fxml file with just the toolbar. Then use the <fx: include /> tag in your other fxmls to include the toolbar. This is like a "component".
Edit: This is how option 2 can work in practice.
Say toolbar.fxml is the name of the fxml file containing only the toolbar.
Simply include <fx:include source="toolbar.fxml"/> in an other fxml file to incldue the toolbar at that location. See here for more information.
I have an fxml file that references a css file. When I load this fxml and set it as the root of my scene, the css is applied nicely.
However when I create a custom Region (with getChildren made public), and add the loaded fxml node to it, no css is applied anymore.
The css only uses style classes.
What am I missing here?
/edit
I worked around it by using the approach described here:
http://www.guigarage.com/2012/11/custom-ui-controls-with-javafx-part-1
It doesn't answer my initial problem but I guess it's a better way of working anyway.
If someone can still explain the behavior of my original question, I'd be happy to hear it.
The problem was that I used the static load(...) method instead of the instance load method from the created FXMLLoader object.
I was wondering if there is a simple way to clone elements in FXML (such as textboxes) to display them more then one time.
Following situation:
I have a TabView and want to display on the first Tab elements X, on the second Tab elements Y and on the third Tab I want to display X and Y.
Dublicating the same fx:id is not allowed (Netbeans says) and exporting X and Y in different .fxml files, so that I just include them twice, neither works. Thats another problem.
How would you solve this ?
Make a new component with its own FXML. Then you can just include as many as you want.
One way to achieve this is to implement a custom java class that extends a javafx component (Pane or VBox for instance), then in the constructor of this class you load the FXML of its layout. With FXMLLoader you set the controller and root as the current component and you use the fx:root tag in FXML.
You'll have a component with a java class which will be the root and controller of its own FXML.
I would generally suggest splitting the whole .FXML into 3 different pieces which can be maintained seperately.
TabView, SplitPanes and all containers like this should be in a standalone FXML and each new pane in another one. In your case:
TabView = 1 FXML
Tab 1 = 1 FXML
Tab 2 = 1 FXML
You can export them in that way, but the elements need a container like HBox or something simple (like the Pane you need to create when you start SceneBuilder or your root Parent)
JAVA's abstraction is somehow brought out by allowing us to create a JFrame (and save it in its own .JAVA file) and populate it with different kinds of objects such as JPanels, JTextFields ... (saved in different files) if and when needed by using the remove(), add(), validate(), repaint() methods.
I'm trying to move my JAVA project to JAVA-FX due its great flexibility in design via JavaFX Scene Builder and css. Are there any equivalents to the above methods here (In JAVA-FX)? Is there a way I could create a Pane or a Label ... and save it in its own file as it waits to replace onother Pane with its own child Nodes (and saved in its own file) on the Stage later when it's called via an action, such as a button click?
Would really appreciate any help. Sample code enumerating the above could help also.
Thank you all in advance.
Your's trully, Complete JAVA-FX Newbie.
In a regular JavaFX application, there is only one primary stage and its one scene. Create your FXML file (optionally with its controller) containing any JavaFX node and load this file on button action using FXMLoader. Then you can use the loaded node as a root of scene;
scene.setRoot(MYNode) (though only Parent can be set as root)
or add it to subtree of root node as a child;
if you know the substructure: scene.getRoot().getChildren().get(3).getChildren().add(MYNode);
if you know the id: scene.lookup("myPane").getChildren().add(MYNode);
The same logic applies to another FXML file(s) being loaded in another action event.
I have created a Node (AnchorPane) in the JavaFX scene builder and was wondering how to clone it.
I saw Duplicate/Clone Node in JavaFX 2.0 but I need to clone the Node without re-loading the fxml.
Is there any way to achieve this in JavaFX 2?
You can place the component that needs to be duplicated in a separate .fxml file.
Then you can load the separate file as many times as needed adding the nodes to the appropriate root in the main scene.
Additionally you can edit an <fx:include source="..."/> element to the main .fxml file and include the separate .fxml file. You can then still work with it in the JavaFX Builder.
There is no such node duplication function in the JavaFX platform, you will need to write your own which introspects on the properties of the node you are interested in cloning and creates a new node with the required properties.
Using an fxml template for the node definition is probably the easiest way to do this for node's with static initialization properties - but then, as you state in your question, you don't want to use fxml for this, so you'll have to code your cloning logic in Java.
