TextField t1 = new TextField();
t1.setMaxHeight(50);
t1.setMaxWidth(140);
This is the code I use to define a TextField in JavaFX. I think setMaxHeight() method is not working because size is not changing even if the value is changed.
So I tried setPrefSize(), but it too has a problem. The height property is working fine in it, but width is larger than I specified.
How to solve the above issue ?
This is very similar to how swing components work with a layout manager. In javafx the parent pane will adjust the size of nodes so a size that fits. I bet if you give the pane more room the nodes will fill out to their preferred size.

I'm building a JavaFX desktop app using scenebuilder for the UI.
Here i have a tilepane inside of a scrollpane, i couldnt use the "fit to parent" option from the context menu in scene builder, i guess the solution is to give them -fx-id's and bind their width in the controller ?
I dont want to use any values so it all comes together nice when the user resizes the window.
how should i go about doing this?
I got the task to draw some points on a map. Wrote some code but currently every point I create via shapes will be added to the wrong position inside of my gridpane. Oh and I'm using JavaFX.
I added an imageView to the index 0,0 of my GridPane and every point is created through x and y position of the MouseEvent on the imageView.
After that I added the created point as a child of the GridPane and it's displayed at the center of the y-axis of the first grid.
Tried different things like anchorPanes and canvas but can't seem to get it working.

I hope that's enough ^^'
pls help!

GridPane is a managed layout: it will position nodes that are added to it via the properties you set (using defaults if you don't set them). So when you add your circles to the grid pane, since you don't set any properties, it will place it in cell (0,0) and align it within that cell using default settings; i.e. it ignores the centerX and centerY properties.
What you should really do here is use a layout that does not manage the positioning of the nodes for you, such as a Pane (or possibly a Group). You can put the ImageView and the Circles in the pane, and then place the pane in the rest of your layout (in the scroll pane, I think).
The other option you have is to call setManaged(false) on the nodes you add to the GridPane in order to instruct the GridPane not to position them, though this feels like more of a workaround.
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 created a FXML file using JavaFX Scene Builder 1.1. An AnchorPane is created by default. Why can't I modify the resizable attribute?
Do you want to disable window resizing? If so, you can do that in your application program:
stage.setResizable(false);
Why you can't edit bounds
Checkout the javadoc on layoutBounds and boundsInLocal. You will notice that both are ReadOnlyObjectProperties, which is why you can't directly modify them in SceneBuilder.
How to resize a node in SceneBuilder
You can indirectly effect the bounds properties and directly set the resizable properties of the node by altering the min, pref and max height and width.
You can also set the pref size by selecting the pane to be resized and dragging the resizing anchors the surround the selected pane.
Further Information
You might want to read the Oracle tutorial on Tips for Sizing Nodes and Amy Fowler's presentation on JavaFX layout.
You can change resizeble using code
primaryStage.setResizable(false);
I´m using JavaFX scene builder now for the first time and I´m wondering if there is any fill_parent setting to let for example the menu bar always have the size of it´s parent, even if the window is rescaled by code.
Is there any appproach to have such a behavior in the designer?
There is the function "Fit To Parent" that can be found by right-clicking on an element in a container. This function is not available for all containers, what container do you want to fill?
