I'm trying to layout a Stage using a GridPane as the root of the Scene.
row 1 contains a HBox
row 2 contains a SplitPane with orientation set to Vertical
The SplitPane contains a browser control and another SplitPane with orientation set to Horizontal. The inner SplitPane contains two TableViews.
I'm try to have the outer SplitPane resize as the window changes size (please forgive if I'm not using the correct terms). I've seen how this can be done when using fxml but I'm restricted to using Javafx 8 and must do this programmatically. If it matters I'm using Netbeans 8.1.
It would be most appreciated if someone could point me in the right direction.
thank you

It turns out the solution to resizing the outer SplitPane was to use the type's static setResizableWithParent method.
SplitPane.setResizableWithParent(outerPane, Boolean.TRUE);
With that addition the SplitPane resized vertically but was limited horizontally by the width of the GridPane. The grid only contains one column so setting a ColumnConstraint's PercentWidth property to 100 allows the grid and SplitPane to resize horizontally.
Try this code,
yourSplitPane.setMinSize(500, 400);
yourSplitPane.setMaxSize(500, 400);
Here, 500 is width and 400 is height.

I was learning javafx and came across these two statements which I don't know their difference.
Pane pane = new Pane();
and
StackPane pane = new StackPane();
Can somebody enlighten me about the difference and when to use which?
Both are layouts but the Pane is the basis of all the other layouts, the difference is that the Pane offers a free positioning of nodes, and The StackPane (and other Node with the suffix Pane called Built-in Layout) in return, follow their own logic (Positions/Constraints...). The 'StackPane' for example lays out its children in a back-to-front stack StackPane. This is only superficial and limited information, here's a good tutorial : Layout in JavaFX
The difference between both layouts is positioning of the children and the resizing of resizeable children.
Pane does not do any positioning. The child's layoutX and layoutY are left unmodified. Furthermore resizeable children are resized to their preferred sizes.
StackPane determines the position of children based on the alignment set for the child itself or the one set for the StackPane itself, if no position is set for the child. Resizable children are resized to a size that fits the StackPane's size best (still taking into account max size). Both can be modified by a margin set for individual children...
I have created TreeTableView by coding. Then I created 2 fxml files. one(overview.fxml) has splitpane(left side is label andand button and right side nothing) and the other(RootLayout.fxml) one with a menu bar which wraps the first one. How can i set bind my treetable view which is in main class to the right side of splitpane?
try this sorry for the earlier blunder
SplitPane sp = FXMLLoader.load(getClass().getResource("/overview.fxml"));
StackPane container = new StackPane();
container.getChildren().add(YourCreatedTreeViewNode);
sp.getItems().add(container);
sp.setDividerPositions(0.3f, 0.6f, 0.9f); // you can tweak it any how
SplitPane two or more sides, each separated by a divider, which can be dragged by the user to give more space to one of the sides, resulting in the other side shrinking by an equal amount. Nodes needs to be placed inside a layout container before they are added into the SplitPane. If the node is not inside a layout container the maximum and minimum position of the divider will be the maximum and minimum size of the content.
Safe to say you just add your nodes to the SplitPane and it will do the positioning..
hope it helps
I need a scaled ImageView with a Canvas overlay, stretched over the parent, with a constant margin on the right hand side. This suggests an AnchorPane with the ImageView and Canvas as children, each with a rightAnchor inset representing the margin.
I need to put the AnchorPane in a ScrollPane. The ScrollPane must, when resized, resize both the ImageView and the Canvas overlay within the AnchorPane, while retaining the margin.
I have tried adding the ImageView and Canvas to the AnchorPane, and adding the AnchorPane to the ScrollPane, with ScrollPane.setFitToWidth(true). When I increase the size of the ScrollPane, all works well - both the ImageView and Canvas expand to fill the ScrollPane, retaining the margin on the right hand side.
However, when I reduce the size of the ScrollPane, the size of the AnchorPane is not reducing, but instead the viewport over the AnchorPane is reducing, with increasing scrollbars.
NB, an ImageView inserted directly into the ScrollPane does work - it rescales both on grow and shrink.
It looks as though ScrollPane.setFitToWidth behaviour differs depending on the container inside the ScrollPane.
Is this correct, and can anyone suggest a solution, please?

Try adding a listener to one of the ScrollPane's Bounds properties and reduce the AnchorPane's size from there when appropriate.
Solved using Jurgen's answer.
I overrode AnchorPane.computeMinHeight, computePrefHeight and computeMaxHeight to return imageView.minHeight, prefHeight and maxHeight. This ties the anchor pane's height to the imageView's height - which the imageView calculates from its own width.
Then I added a listener to the scrollPane.widthProperty which calls the AnchorPane.setPrefWidth, setMinWidth and setMaxWidth
In this way, the anchor pane is correctly signalling its preferred, minimum and maximum width to the enclosing scrollPane.
I have this ScrollPane which I holds many components. I want to use the ScrollPane into many components with different size.
I solved temporary the problem using Rectangle2D
Rectangle2D primaryScreenBoundsthree = Screen.getPrimary().getVisualBounds();
But this is not working properly when I insert the ScrollPane with different components. I also tested this:
scrollthree.setPrefSize(ScrollPane.USE_PREF_SIZE, ScrollPane.USE_PREF_SIZE);
But again the result is not appropriate:
How I can fir the ScrollPane into the parent components borders?
Screen.getPrimary().getVisualBounds();
This returns you the bound of the Screen(Monitor) which you are using.
Bounds is the width and height of the Screen !
Inorder to use scrollPane to fit into your parent, don't use scrollthree.setPrefSize. You don't have to specify the size of the scrollPane, it will automatically fit into Parent
Infact, all the javafx panes fit into their respective parents !
I have a problem in flex scroll bars. I have a mxml component based on canvas. Inside that I have used a VBox for my form. Above that Vbox I have another canvas just for title.
My form gets longer than normal screen size when the grid inside that is filled with more data. In that case I want a vertical scroll bar just for Vbox in which my form is located. But the whole canvas is getting scrollbar including title canvas. how to solve this problem.
I set vertical scrollbar policy of main canvas to off and inside Vbox's VerticalScrollbarPolicy to on. but that's not working. It is not overriding the property of parent container.
Thanks.
Keep your Form inside a Canvas inside the parent canvas instead of VBox. VBox and HBox are set to grow automatically in the parent container, so if your form grows, your corresponding VBox will grow as well.
You want to overload the "updateDisplayList" function for your parent canvas, and force the height of your form Vbox to be canvasHeight-titleHeight (including padding, space, etc...) so that the VBox never grows larger than the screen. This will solve your problem. Just make sure you check for the existence of the VBox as sometimes the updateDisplayList will be called before it has been instantiated.
Had the same problem myself and decided to take the easy route.
Have the following
App->vbox->[vbox + hbox]
components are dynamically being added to last vbox. Wanted hbox to stay on screen and have scrollbars only in vbox above it(2nd vbox).
Was experiencing the same problem. All containers had scroll policy=off except for last vbox, but when dynamically adding components, when the components filled the vbox > 100%, the outer vbox would start to scroll.
Resolution was simple once I went back to the documentation.
Set scroll policy - horizontal and vert on app and first vbox to off, and also added autoLayout=false. This causes the engine to not resize the components after initialization, ie, they are static sized.
Once I added this property, no more scrollbars except for the inner vbox.
Tada!
