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)

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.
My goal is to have a program with 3 panes. A mulitfactor Auth. The first pane will have the user type in a passphrase, while the second pain will allow the user to pick a image from a drop down list. But I want the 3rd pane to launch just to the right of the 2nd pane after the use selects a image in the same "Main" stage.
Not looking for someone to code a program just point me in the right direction to what im trying to do. My searching skills are failing, either im not explaining it right or theres another word for this.
Edit:
This is my idea of how i want it to work. Now that i look at it using a border pane probably makes since, But im still stuck with, How can I launch each section of the border at a different time, i.e when something is clicked.
I would go about it by having 3 panes side by side and just blank for the first FXML file you load in. I would then have another FXML file with the same layout that contains what you want to show up in those panes.
Then with that, you can have the controller on request (like when a user hits submit or however you are wanting these to show up) grab the content inside of the pane on the second FXML file by ID and load it into the pane.
I've done something similar with changing anchor panes and keeping the toolbar from the original so I can add more on this when I get home and should be able to supply some code that is modified to fit your issue.
Edit 1: Sorry I was in a hurry to submit that dive I had to go but I am on mobile now so I can edit but not able to add a lot, just felt I needed to say, there are different options for what you can use to do this which is why I just said a pane instead of anything specific. Just wanted to submit something so you can start looking in the right direction till I am able to update.
Edit 2: Alright now that I am home I tried this out and was able to get this working. Here is how I did it.
So I had two FXML files. One with the 3 areas that you have your items, however, only the box that you want to show when it starts is shown. Each area is enclosed by an AnchorPane. I used the AnchorPane as a container so I can swap out what is inside of it. I then had a second FXML file that had all of the boxes you want to show all of which enclosed in AnchorPanes. Here are pictures explaining what I mean.
I have the first pane named initial.fxml and the second named grabfrom.fxml. For the pane names, I just have it as pane1, pane2, and pane3. Lastly, the methods I have are show2() and show3() and call them from the FXML when the respective buttons are clicked inside of the AnchorePanes.
With initial, I just load that up as normal from the start method in my main class and that is all that is needed to be done with that. We only had it so we could display something that does not have the boxes showing before needed.
Now for the important part
With what I have in show2(), which is called when the button inside of the first pane (which is there from the start) is pressed.
public void show2() throws IOException{
AnchorPane toSetPane2=(AnchorPane) FXMLLoader.load(getClass().getResource("grabfrom.fxml"));
toSetPane2=(AnchorPane) toSetPane2.lookup("#pane2");
pane2.getChildren().setAll(toSetPane2);
}
What this is doing is loading the grabfrom.fxml into a temp var that we cast to an anchor pane. (Do note that this works since as you can see in the screenshot the whole FXML file is an anchor pane. If you're not using it that way you can take out the casting and cast to something you are using or not even cast depending on what it is.)
It then set the var we just made to just the AnchorPane we need, which is the second one since that's the one we are adding. It does this with the .lookup("#ID"); method to get just the pane we need.
Lastly, it sets everything inside of the current pane2 to toSetPane2.
This could all be compressed down into one line, however, I have left it as is for easier reading.
You should be able to use this method of loading in a portion of your application for loading in the third one and for that matter any other parts you want to in any situation.
Edit 3:
Also as #Swatarianess had said, there are stackpanes, this method will work with anything that you can set an ID to so they would work just as well. I used AnchorPanes because I have done a fair bit with them and had some code I could recycle whilst making a test for it so it was easier. All you would do if you were using those though is just cast to a StackPane instead of an AnchorPane like this:
public void show2() throws IOException{
StackPane toSetPane2=(StackPane) FXMLLoader.load(getClass().getResource("grabfrom.fxml"));
toSetPane2=(StackPane) toSetPane2.lookup("#pane2");
pane2.getChildren().setAll(toSetPane2);
}
The transition between panes could be done with a stackpane.
I am currently working on some GUI using JavaFX and JavaFX Scene Builder. I've met an issue and it is not that easy to find a solution for it (at least for me). I'd would like to get something like this:
http://i.imgur.com/oN4mIVl.png
And the point is that after click on the TreeItem "Sample" only the right side of the window will reload. I would like to do it also using fxml files.
I know that I can include one fxml in another but that's not the solution. There might be a lot of TreeItems, and every TreeItem should load another pane configured by another FXML.
Can you guys at least steer me on the good track, please?
(Sorry the image is in link but I do not have 10 reps yet as I'm new here...)
Have you tried to load the node and setting the node on the right?
Node root = FXMLLoader.load(getClass().getClassLoader().getResource("fxml/yourfxml.fxml"));
borderPane.setRight(root);
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?
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.
