Maybe the title of my question is not good but actually I don't know how to name it.
So I will try to explain my problem really clearly.
So I want to know if its possible to make like a "ErrorBar" inside my scene. I understand by this to show this element over other node inside the scene for a short time.
I have a BorderPane and I want when I have an error in my application (like webservice error) to show the error to the user. And for that I want to move a gridpane from the right to the left of the screen without change my scene (like put this object in the top of the borderpane).
I don't have any example with a software who do it but I think some stuff in Javascript can do something like this. Just show a green or red bar in the top of the website event it's somthing already show.
If someone know how to do that it will be great.
Actually I use Java 8 latest version.
Feel free to ask more if you want to know more about my question.
Thanks in advance.

I think you can just use a StackPane which allows you to work with "layers". Indeed in the StackPane, each Node you add to it becomes a "layer" and appears above previously added Nodes. Meaning that the latest Node will always be on top.
Knowing that, you can add your error message to the StackPane and then, if you use a transition to move it, at the end of the transition you automatically remove the message from the StackPane.
Hope it helps.

I am in the process of creating my first JavaFX application. I use SceneBuilder to design the GUI. I am facing the following problem:
I have dragged a Pane inside the GridPane. The Pane seems to have to follow the constraints given by RowConstraints and ColumnConstraints. The problem is that these are not aligned with my pane:
I did not expect this to be a big problem, but this results in a gap that is visible when I run my code:
I am talking about the white-colored part in this figure - I want this to be blue. Also, I want to see the entire pane in my window.
I played around and tried to figure this out on my own, but I don't see what I am doing wrong. Any ideas?
What seems to fix the issue is the following:
Inside the Inspector, open the Layout-entry for ColumConstraints. Change HGrow and HAlignment from INHERIT to ALWAYS and LEFT, respectively.
But if anyone knows more about this, feel free to post a separate answer!
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'm developing a small GUI using JavaFX for an assignment. Having never used JavaFX before, most of what I've used or learned I've research myself. Most of my application runs smoothly, animations included.
I have a small user input section:
I'm trying to allow it to swipe left prior to loading the next scene, to give the user the impression of sequence. I achieved this using a ParallelTransition populated by TranslationTransitions in which I load all of these Nodes.
However, just slightly before it animates, it appears to align everything right.
I have a feeling this is something to do with the container (AnchorPane) in which I'm placing these objects, or some undefined attribute which I'm not setting. As I'm learning this all on the fly, it's a bit difficult to narrow down. Can anyone give me an idea as to what is causing this and how I can retain the alignment? Each Node moves in the following way:
translateTransition.setFromX(node.getLayoutX());
translateTransition.setToX(node.getLayoutX()-500.00);
If I've left out any pertinent information, please let me know!
So, my issue turned out to be the way I'm laying out my objects. Placing them in an arbitrary AnchorPane with only specific attributes to locate those items means that, upon animation, it will group those objects and animate them accordingly. It was the incorrect way to layout those nodes.
Instead, I've placed them in a VBox which has two advantages.
I can align the contents of that VBox centre, so I need not specify the exact layout attributes of the elements.
I can animate using the single VBox, as opposed to the all the elements in a ParallelTransition. As a result, a single TranslateTransition on the VBox node will suffice!
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);
Right now, I'm using Java Swing to create a JEditorPane primarily for its ability to have hyperlinks. I've successfully been able to display links and have them execute behavior upon a click, but I'm running into a few problems with formatting.
How can I set the cursor so that it normally is an arrow, but changes to a text cursor when hovering over text? (In essence, the behavior a cursor has within a web browser). I tried
EditorPane.setCursor(new Cursor(Cursor.TEXT_CURSOR))
but that made it a text cursor everywhere, even when not hovering over text. Right now, hovering over a link shows a pointer hand; I'd like to maintain that functionality as well.
What is the best way to show tooltips or mouseover text when hovering over a link? I tried modifying the title attribute of the link but nothing showed up.
I was trying to implement links to skip down to a subsection of the page, much like http://en.wikipedia.org/wiki/Xkcd#History would take you directly to the History subsection of Wikipedia's xkcd page. How can I do this?
An answer to any of these would be great (and multiple would be awesome xP). Thanks a lot for your help!
As you said one can simply give answers to a single point as well, let me try one by one, here is the answer for your last Point 3
Just provide an id to your tag like this
<h1><a id = "top"></a>First Line</h1>
Now somewhere in the bottom of your page write this :
<p>Return to TOP</p>
Clicking this link, you will reach the above area of the PAGE.
Points 1 & 2 may be addressed using the approach mentioned here. In particular, the view/model conversion methods will let you condition setCursor() and getToolTipText(), respectively.
You can get source from here http://java-sl.com/JEditorPaneStructureTool.html
It shows how to obtain text view bounds. First you get caret position for current mouse poiunter using viewToModel() method. Then go down the Views tree achieving leaf view and calcualte it's bounds. See this http://java-sl.com/tip_view_rectangle.html
If your mouse pointer in the view's rectangle then your mouse over text.
You can check whether the text in caret position is link and show your tooltip.
Use this http://java-sl.com/tip_links_in_editable.html to see how to detect whether mouse is over link.
