Putting a custom node as content on a TitledPane is fairly easy, but how can I set a node as the title of a TitledPane?
Can't really find anything on the subject, to a point where I start thinking it's not possible to do something other than
titledPane.setText("My title")
But that can't be, can it ?
Use the graphic property of the TitledPane:
HBox hbox = ...
TitledPane titledPane = new TitledPane();
titledPane.setGraphic(hbox);

I am trying to change hbox cell width via changing child node width in the hbox
Hbox hbox = new Hbox(new Label("node1"), new Label(node2), new Label(node3));
//Lets say I wanna change the lable says "node3"
//i tried below option. did not work
hbox.getChildren().get(2).maxWidth(150);
node.maxWidth() is invoked by layouts to query the maximum size of the node, to change child width (label) cast it then use the setter
((Label) hBox.getChildren().get(2)).setPrefWidth(150);
Hi I'm trying to create a simple layout that looks like this using JavaFX.
I would like the user to be able to drag/resize the middle bar. I've tried to make this using a GridPane. But I can't figure out how to get the middle resized. Perhaps GridPane is not the way to go. Both panes will contain a lot of other program code later on. Thanks!
Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
stageRef.setMaxWidth(primaryScreenBounds.getWidth());
stageRef.setMaxHeight(primaryScreenBounds.getHeight());
GridPane gridPane = new GridPane();
gridPane.setGridLinesVisible(true);
gridPane.setPadding(new Insets(10));
Scene scene = new Scene(gridPane);
VBox vBoxMain = new VBox();
vBoxMain.setPrefWidth((primaryScreenBounds.getWidth()/5)*4);
vBoxMain.setPrefHeight(primaryScreenBounds.getHeight());
TextArea textArea = new TextArea();
textArea.setWrapText(true);
textArea.setPrefHeight(primaryScreenBounds.getHeight());
vBoxMain.getChildren().addAll(textArea);
vBoxMain.isResizable();
VBox vBoxSide = new VBox();
vBoxSide.setPrefWidth((primaryScreenBounds.getWidth()/5));
vBoxSide.setPrefHeight(primaryScreenBounds.getHeight());
vBoxSide.isResizable();
gridPane.add(vBoxSide, 1,1,1,1);
gridPane.add(vBoxMain, 2,1,4,1);
stageRef.setScene(scene);
stageRef.show();
You could use a SplitPane:
A control that has 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.
Then you add two others containers to this pane allowing the user to change the position of the divider. You can also set minimum widths for each component within the pane or set the position of each divider within your code.
I am trying to learn JavaFX and I've run into a problem with the Menus in my MenuBar. Here is a minimal example:
public void start(Stage mainStage) throws Exception {
BorderPane root = new BorderPane();
Scene scene = new Scene(root, 1200, 1000, Color.WHITE);
MenuBar menuBar = new MenuBar();
Menu menuFile = new Menu("_File");
menuBar.getMenus().add(menuFile);
MenuItem add = new MenuItem("_New");
menuFile.getItems().add(add);
root.getChildren().add(menuBar);
menuBar.prefWidthProperty().bind(mainStage.widthProperty());
mainStage.setScene(scene);
mainStage.show();
}
This application starts, but the Menu in the MenuBar is only shown as three dots (...). It does open however when I press ALT+F, so it is there.
From what I understand, a Menu item has no width or similar attribute, so that can't be set. I suspect it has something to do with my root node being a BorderPane, because in every other example I found that works, the root is either a VBox or something else. I seem to get the desired results when I place a Vbox as my root node, and then add the MenuBar and the BorderPane` to the root - but that seems like a strange and uneccesary workaround to me.
So what am I missing here? Is it true that a MenuBar will only ever look like it should in certain containers? What is the difference between a BorderPane and a VBox in this regard? If someone could explain or point me to a part of the documentation that I've missed, I would be very thankful.
You are using a BorderPane and using getChildren().add() to add MenuBar in it, which is incorrect. BorderPane unlike VBox, can't accept any number of children and is divided into 5 specific positions :
top
left
right
bottom
center
The children goes into any one of these positions. Please go through the documentation for BorderPane.
You need to add the Menubar to the top of the BorderPane using :
root.setTop(menuBar);
I'm quite new to JavaFX and I have two methods - one returning a grid layout and the other one returning a HBox with a MenuBar, but fot the life of me I can't make it, so it's not overlapping (I want the grid to be a few pixels lower). I have this code in my start method:
final Group rootGroup = new Group();
final Scene scene = new Scene(rootGroup);
rootGroup.getChildren().add(addBar(stage.widthProperty()));
rootGroup.getChildren().add(addGridPane());
stage.setScene(scene);
stage.show();
How do I fix this?
You may use another Layout Manager as root. For example:
final VBox rootGroup = new Vbox();
Then all its children will be aligned vertically.
I have a FlowPane with many BorderPanes as windows. I would like to display something like water mark or label <empty> when the FlowPane is empty.
Is there any solution?
Have you tried something like this:
FlowPane flowPane = ... ;
StackPane container = new StackPane();
Label placeHolder = new Label("No content in flow pane");
placeHolder.visibleProperty().bind(Bindings.isEmpty(flowPane.getChildren()));
container.getChildren().addAll(flowPane, placeHolder);
Then, obviously, just add the container into your UI where you previously added the flow pane.
