The problem
In code it works perfectly if i do it like:
TilePane tilePane = new TilePane();
ScrollPane scrollPane = new ScrollPane(tilePane);
I mean that every time the TilePane has more items that can be shown then a scroll appears vertically or horizontally without adding any extra code or setting minimum or preferred size of TilePane.
Using SceneBuilder
Instead of using pure code i want to have the same result as the above using SceneBuilder but every time i am trying to do it something like this: happens
I have to set the preffered size to the TilePane.Why thought? And it doesn't work as expected.I want it to automatically work as described in the first lines of the question.A good description is needed...
See the prefWidth and prefHeight to USE_COMPUTED_SIZE. These are the default values for a TilePane, but SceneBuilder seems to set them to default numeric values when you drop the TilePane into a ScrollPane.
You can select these values directly by clicking on the drop-down boxes next to the text field for the prefWidth and prefHeight text fields.

I have a TableView generated with SceneBuilder and all the columns are FXML imports from other views, until there no problem, but the columns don't fill the width.
I tried to fix this with scene builder and FXML, but no luck, all the sizes are computed.
I tried to code it with a change listener that checks every time the window changes size to adapt the size of the columns.
This works and the columns resize to the proper width (basically I am getting the table view width and divide it by the number of columns), but for some reason the point where the column starts doesn't change and they overlap with each other.
Any suggestions?
Select the TableView in Scenebuilder an go to the Properties an change "Colum Resize P..." to the value > "constrained-resize":
Normally thats all you need.
If that doesn't work, you can try to reset the columns values:
Select all columns you have at the same time
Go to Layout and change all setting to the settings in the picture
This should work.
i have a little problem to layout a TableView inside a ScrollPane :
i want to know how to make the TableView always fit inside the ScrollPane, What happen is :
when i make the windows small everything work good there is a scroll bar and that work
but when i make the windows larger the TableView don't grow with the ScrollPane, so how to make it work, i have tried to set fitWidth of ScrollPane to true, but if i do the TableView Column are just resized with the size of the window there is no scrollbar
If you are using scene builder to construct your fxml, it's very easy to do this. Just select the scrollPane which wrap your tableview and check option "Fit to Width" in Layout. However, you can also do the same work in code by checking your scrollpane object but not tableview object.
The solution is to put TableView in UNCONSTRAINED_RESIZE_POLICY mode
I want to create a scrollable timeline controller with circles connected to a baseline filled with a number ( size of circle corresponding to containing number) and a trailing icon.
Since I am new to JavaFX i have no idea how to start. In Swing i would e.g. use JPanel and ovverride its onPaint() method to draw the circles, lines and icons...
In JavaFX I thought about using a horizontal ListView with custom ListCell, but i am not sure if the baseline is possible with it. So i am looking for ideas how to implementiert such a controll...
Try using a HBox wrapped inside a ScrollPane.
You can add elements to HBox using getChildren.add(node). The elements will be automatically shown on the scene and the ScrollPane will adjust the ScrollBar for you.
So I've been searching around and for the life of my cannot figure out how to correctly do this. I simply have a small text area and want to be able to scroll through it. I've been told it's as easy as adding the TextArea to a ScrollPane, but it appears to be more complicated than that. Here's the gist of my code:
Skin defaultSkin = newSkin(DEFAULT_SKIN_FILEPATH +"uiskin.atlas", DEFAULT_SKIN_FILEPATH
+"uiskin.json");
TextArea textArea = new TextArea(levelLoader.getCodeSnippet(), defaultSkin);
ScrollPane pane = new ScrollPane(textArea, defaultSkin);
pane.setForceScroll(false, true);
pane.setFlickScroll(false);
pane.setOverscroll(false, true);
pane.setBounds(0f, 20f, game.getWindowWidth(), 300f);
gui.addActor(pane);
Gdx.input.setInputProcessor(gui);
setIsCreated(true);
levelLoader.getCodeSnippet() returns a string containing a multi-line piece of text from a .txt. The TextArea appears in the game window, and the multi-lined text also appears. However, I can only scroll through the text with the arrow keys. I forced the scrollbar to display itself, but it occupies the entire right side of the window like this:
http://s27.postimg.org/vqws36k77/pic.png
It will not scroll and thinks there are not multiple lines to scroll through even though there are evident by scrolling through with the arrow keys. I've also tried making the textArea larger than the scrollPane, but might have done it incorrectly. What am I doing wrong here?
Update: I've tried both placing the ScrollPane inside of a table and setting the cell size of the table. Any other suggestions would be appreciated.
This is not best solution. I guess it is LIBGDX update layout bug.
This is workaround solution that works for me:
Set pref. rows manually and update scroll layout, when the number of the rows is changed.
textArea.setPrefRows(numberOfScrollLines);
//numberOfScrollLines = text.split("\n").length
pane.layout();
I used textarea in javafx 2.0 but i need to add it scrolpane.how can i do that?
Scrolllpane s = new Scrollpane();
s.setnode(textarea);
but when i click on scroll pnane it has doesn't move.
what is problem?
setNode() is the right method to call to set the node that the ScrollPane will scroll over. I've used ScrollPane extensively in my 2.0 app, but I have not tried it on Text Area. Based on the API documentation for TextArea (http://download.oracle.com/javafx/2.0/api/com/javafx/preview/control/TextArea.html) it sounds like it has its own built in scroll bars? I would try setting the width/height of the TextArea, and also set the max width/height, and see if you can trigger scrollbars to appear automatically when the lines in the text area exceed the available space.
If you still want to put it in a ScrollPane, perhaps with some other nodes, you should use a container node such as VBox or something to wrap the TextArea, then set the VBox to be your scroll node on ScrollPane.
Also, bear in mind that TextArea is not a committed control for FX 2.0 yet and is therefore less hardened than the other FX controls.
When we create a text area, scroll bar automatically appears when it goes beyond t
