I have a few UI elements that I want stacked vertically, in the center of the panel, all aligned on the left edge of the center. I've tried to do this with a VBox, and it was working until I added an item that had text that was too long; it always truncates the text with ellipsis's and I can't get it to wrap the text down to the next line. I set the wrapText param to true on the Checkbox, but it doesn't seem to respect it. I've tried setting perfWidth and maxWidth on the checkbox and the vbox it is inside of but nothing seems to work. Can anyone tell me what I am doing wrong?

EDIT - as #jewelsea pointed out below, the issues was BASELINE_CENTER in the root VBox; changing that to center removed the truncation issue. This had the unintended side effect of making the outside around the radio boxes extend farther than I liked:
by adding
<maxWidth><Control fx:constant="USE_PREF_SIZE" /></maxWidth>
to the inner VBOX I was able to correct this:
I also found out, that if for some reason I was wed to BASELINE_CENTER, I could still fix the issue with the checkbox text by adding
<minWidth><Control fx:constant="USE_PREF_SIZE" /></minWidth>
to the checkbox to get the same effect.
This is what I came up with, try it and see if it is what you want.
You may need to change some things to reach your final desired layout, but hopefully this addresses your immediate wrapping issue.
I think the BASELINE_CENTER alignment on the outer VBox was confusing things, but I changed a couple of other things, so it may have been something else.

I have a simple JavaFX application, a BorderLayout with an AnchorPane and inside two panes, one contains a HBox and a VBox with a TextArea and a ListView. I would like them to increase in width, as I increase the window size. I have tried Vgrow/Hgrow = 'ALWAYS' and Max Width/Max Height = 'MAX_VALUE' on the the controls but nothing works.- (I use Scene Builder to create the fxml)
The FXML is the following:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.ListView?>
<?import javafx.scene.control.TextArea?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.BorderPane?>

My java application class (HelloApplication):
package com.example.demo;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
public class HelloApplication extends Application {
#Override
public void start(Stage stage) throws IOException {
FXMLLoader fxmlLoader = new FXMLLoader(HelloApplication.class.getResource("hello-view.fxml"));
Scene scene = new Scene(fxmlLoader.load());
stage.setTitle("Hello!");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch();
}
}
UPDATE: I removed the unnecessary AnchorPane and other Panes, kept only a VBox and placed it in another BorderLayout, take a look, now seems perfect :)
Don't hard-code sizes, and don't use layout panes such as Pane and AnchorPane that rely on hard-coded sizes except in very rare circumstances.
(You may sometimes need to set the max size to Double.MAX_VALUE to allow a control to grow beyond its preferred size, but even that is not necessary in this example, as far as I can tell.)
Your FXML has an empty Pane and at least two redundant wrapper containers which only wrap one node (the other Pane and the AnchorPane). Remove all of these and the hard-coded values and it will work:
<?import javafx.scene.control.ListView?>
<?import javafx.scene.control.TextArea?>
<?import javafx.scene.layout.*?>
<BorderPane xmlns="http://javafx.com/javafx/18" xmlns:fx="http://javafx.com/fxml/1">
<center>
<HBox>
<children>
<VBox HBox.hgrow="ALWAYS">
<children>
<TextArea VBox.vgrow="ALWAYS" />
<ListView VBox.vgrow="ALWAYS" />
</children>
</VBox>
</children>
</HBox>
</center>
</BorderPane>
Depending on your real use-case, you may not need the HBox either:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.ListView?>
<?import javafx.scene.control.TextArea?>
<?import javafx.scene.layout.*?>
<BorderPane xmlns="http://javafx.com/javafx/18" xmlns:fx="http://javafx.com/fxml/1">
<center>
<VBox>
<children>
<TextArea VBox.vgrow="ALWAYS" />
<ListView VBox.vgrow="ALWAYS" />
</children>
</VBox>
</center>
</BorderPane>
I have an issue since I do how know, how to add new components to fx:root container child.
This is what I have at the moment.
Root element called PopupContainer
<fx:root type="StackPane" alignment="CENTER" xmlns:fx="http://javafx.com/fxml"
styleClass="popup">
<VBox alignment="CENTER">
<HBox alignment="CENTER">
<VBox fx:id="content" alignment="CENTER" spacing="5" styleClass="whiteBackground, blackborder"
fillWidth="false" StackPane.alignment="CENTER">
<!-- this is where I would like to add components -->
</VBox>
</HBox>
</VBox>
</fx:root>
I have controller for it as well.
Now, I would like to use it like this in some other fxml:
<PopupContainer xmlns="http://javafx.com/javafx"
xmlns:fx="http://javafx.com/fxml"
fx:controller="com.example.bank.editbank.EditBankPresenter"
styleClass="popup"
fx:id="container">
<!-- those components should go to VBOX up there -->
<ViewTitle label="%editBankUC"/>
<Button fx:id="someButton" text="Click me"/>
</PopupContainer>
Of course, when I add components they go directly under StackPane since it is root of the layout. I tried to override getChildren() method to return VBox children but I got children cycle detected. I do not want to add them programatically since it is more then 300 such cases in application but I can add new tag (instead of for example something else). Thanks!
Answering my own question because I think someone else would like to know this too.
So, as I already had before, this is PopupContainer.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.StackPane?>
<?import javafx.scene.layout.VBox?>
<?import javafx.scene.layout.HBox?>
<?import javafx.geometry.Insets?>
<fx:root type="StackPane" alignment="CENTER" xmlns:fx="http://javafx.com/fxml"
styleClass="popup">
<VBox fx:id="child1" alignment="CENTER">
<HBox alignment="CENTER">
<VBox fx:id="content" alignment="CENTER" spacing="5" styleClass="whiteBackground, blackborder"
fillWidth="false" StackPane.alignment="CENTER">
<padding>
<Insets topRightBottomLeft="10.0" />
</padding>
</VBox>
</HBox>
</VBox>
</fx:root>
And controller PopupContainer.java:
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Node;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import java.io.IOException;
public class PopupContainer extends StackPane {
//refference to VBox from layout
#FXML private VBox content;
public PopupContainer() {
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("PopupContainer.fxml"));
fxmlLoader.setRoot(this);
fxmlLoader.setController(this);
try {
fxmlLoader.load();
} catch (IOException exception) {
throw new RuntimeException(exception);
}
}
//note this getter, this is the key that allow you to add childred to child of this component
public ObservableList<Node> getItems() {
return content.getChildren();
}
}
And at the end usage goes like this:
<PopupContainer xmlns="http://javafx.com/javafx"
xmlns:fx="http://javafx.com/fxml"
fx:controller="com.example.bank.editbank.EditBankPresenter"
styleClass="popup"
fx:id="container"
>
<!-- this is what was acceptable to do in question so instead of children I am using items (setter in PopupContainer.java) -->
<items>
<ViewTitle label="%editBankUC"/>
<HBox VBox.vgrow="ALWAYS">
<Pane minWidth="20"/>
<VBox alignment="CENTER" spacing="5">
<HorizontalTextInput fx:id="name" label="%nameUC" alignment="CENTER_RIGHT" />
<HorizontalTextInput fx:id="bic" label="%bicUC" alignment="CENTER_RIGHT" />
<AddressInput fx:id="address" />
<HorizontalCheckboxInput fx:id="active" label="%activeUC" />
</VBox>
<Pane minWidth="20"/>
</HBox>
<HBox alignment="CENTER" spacing="5">
<JFXButton fx:id="close" onAction="#closeView" text="%closeUC" />
<JFXButton fx:id="edit" onAction="#editClicked" />
<padding>
<Insets top="10.0" bottom="10.0" />
</padding>
</HBox>
</items>
</PopupContainer>
I hope it is clear, how to add it. I did not find nothing familiar to this elsewhere but looking at the source of BorderPane can give you a hint how to do it. Cheers
I run a JavaFX program in IDEA on Ubuntu. The window, first, locates on the left-top of the screen, and then I see a jump of the window to a center. How can I handle this?
I've tried different methods of Stage, but it didn't help.
start method

public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("View/MainMenuView.fxml"));
primaryStage.setTitle("Flash Cards");
primaryStage.setScene(new Scene(root, 800, 600));
primaryStage.setResizable(false);
primaryStage.show();
}

I just want the window be in a center immediately when my program starts.
This is a bug in JavaFX itself. A workaround for until it is fixed is to do this:
primaryStage.show();
primaryStage.centerOnScreen();
You need to call centerOnScreen() immediately after show() to prevent it from showing up in the corner.
What am i trying is to align HBox Buttons to center in the Bottom in dialog box.
I want to do this in fxml.However,BorderPane alignment is working in label.
Here is code from my side.I think BorderPane.alignment="BOTTOM_CENTER" must work even if the tag is Bottom.
Class file:
package application;
import java.io.IOException;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class HBoxDialog extends Application {
#Override
public void start(Stage primaryStage) {
try {
Parent root = FXMLLoader.load(getClass().getResource("HBoxDialog.fxml"));
primaryStage.setScene(new Scene(root, 500, 100));
primaryStage.show();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
FXML file:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.text.Font?>
<?import javafx.scene.layout.BorderPane?>
<BorderPane xmlns:fx="http://javafx.com/fxml/1">
<top>
<Label text="this is dialogbox" BorderPane.alignment="TOP_CENTER"/>
<font>
<Font size="35"/>
</font>
</top>
<bottom>
<HBox spacing="10">
<Button text="Okay" prefWidth="90" BorderPane.alignment="BOTTOM_CENTER"/>
<Button text="Cancel" prefWidth="90" BorderPane.alignment="BOTTOM_CENTER"/>
<Button text="Help" prefWidth="90" BorderPane.alignment="BASELINE_RIGHT"/>
</HBox>
</bottom>
</BorderPane>
The BorderPane.alignment static property only makes sense for nodes whose parent is a BorderPane. The Buttons defined in your FXML file have an HBox as a parent, so setting the BorderPane.alignment property on the buttons will have no effect.
You can achieve the desired effect by centering the buttons within the HBox, simply by using the alignment property of the HBox (which positions the HBox's child nodes within its bounds):
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.text.Font?>
<?import javafx.scene.layout.BorderPane?>
<BorderPane xmlns:fx="http://javafx.com/fxml/1">
<top>
<Label text="this is dialogbox"
BorderPane.alignment="TOP_CENTER" />
<font>
<Font size="35" />
</font>
</top>
<bottom>
<HBox spacing="10" alignment="CENTER">
<Button text="Okay" prefWidth="90" />
<Button text="Cancel" prefWidth="90" />
<Button text="Help" prefWidth="90" />
</HBox>
</bottom>
</BorderPane>
This gives
The reason that the Label needs BorderPane.alignment="CENTER" but the HBox needs alignment="CENTER" is because they have different resizable ranges, and in particular their max widths are different. The max width of a label, by default, is its preferred width, whereas the max width of an HBox is infinite. You can see this by setting background colors on them both:
<Label text="this is dialogbox"
BorderPane.alignment="TOP_CENTER"
style="-fx-background-color: aquamarine;"/>
<!-- ... -->
<HBox spacing="10" alignment="CENTER"
style="-fx-background-color: lightskyblue;">
The alignment property positions the content of a node within its bounds. Since the label has no extra space within its bounds for the text to be positioned, with the default settings the alignment property will have no effect. On the other hand, the label is less wide than the top region of the border pane, so there is room to position it within that region. The BorderPane.alignment="CENTER" attribute centers the entire label within the top region of the border pane.
By contrast, the HBox itself already fills the entire width of the bottom region of the border pane. So there is no additional space to align it within that region, and so for the HBox, setting BorderPane.alignment="CENTER" will have no effect. On the other hand, there is more space in the HBox itself than is needed for the buttons, so the buttons (the content of the HBox) can be aligned within the HBox itself using the alignment="CENTER" property of the HBox.
If you want, you can change the max widths to achieve the same effect. For example:
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.Double?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.text.Font?>
<?import javafx.scene.layout.BorderPane?>
<BorderPane xmlns:fx="http://javafx.com/fxml/1">
<top>
<Label text="this is dialogbox"
alignment="CENTER"
style="-fx-background-color: aquamarine;">
<maxWidth>
<Double fx:constant="MAX_VALUE"/>
</maxWidth>
</Label>
<font>
<Font size="35" />
</font>
</top>
<bottom>
<HBox spacing="10" alignment="CENTER"
style="-fx-background-color: lightskyblue;">
<Button text="Okay" prefWidth="90" />
<Button text="Cancel" prefWidth="90" />
<Button text="Help" prefWidth="90" />
</HBox>
</bottom>
</BorderPane>
allows the label to grow (like the default for the HBox), so now its alignment property has the desired effect:
or
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.HBox?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.text.Font?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.Region?>
<BorderPane xmlns:fx="http://javafx.com/fxml/1">
<top>
<Label text="this is dialogbox"
BorderPane.alignment="CENTER"
style="-fx-background-color: aquamarine;" />
<font>
<Font size="35" />
</font>
</top>
<bottom>
<HBox spacing="10" BorderPane.alignment="CENTER"
style="-fx-background-color: lightskyblue;">
<maxWidth>
<Region fx:constant="USE_PREF_SIZE" />
</maxWidth>
<Button text="Okay" prefWidth="90" />
<Button text="Cancel" prefWidth="90" />
<Button text="Help" prefWidth="90" />
</HBox>
</bottom>
</BorderPane>
makes the HBox behave like the button, so now its BorderPane.alignment gives the desired effect:
I am creating a basic game launcher in JavaFX with SceneBuilder. Since SceneBuilder works in FXML, my launcher layout is in FXML. I have a method in my main class that I want to call on a button click. I read that you could use
#methodName
In the button's
onAction
property, but this does not work.
My main Java class:
#FXML
private void launchGame(ActionEvent e) {
System.out.println("Launching...");
}
#Override
public void start(Stage primaryStage) throws IOException {
Parent root = FXMLLoader.load(Main.class.getResource("launcher.fxml"));
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.setTitle("First Week Login");
primaryStage.setResizable(false);
primaryStage.sizeToScene();
primaryStage.show();
}

You need to create a separate Controller class and specify it in top AnchorPane tag with fx:controller="packageName.Classname"
Like this:
<AnchorPane xmlns:fx="http://javafx.com/fxml/1"
xmlns="http://javafx.com/javafx/8.0.102"
fx:controller="com.packageName.Controller">
The called method should be inside the specified Controller class.
com.packageName is just an example, you should use the name of the package where you put the Controller class or no package name if it's not in any package.
