I'm not sure if this is possible and I couldn't find anything on it, but could I make a scrollpane scroll forever?
I am constantly adding new buttons and labels into the window once a button is pressed, and eventually is gets to the bottom.
I may be setting it up wrong but here is code:
BorderPane bp = new BorderPane();
GridPane gp = new GridPane();
Button b = new Button("click");
gp.add(b, 1, 1);
ScrollPane sp = new ScrollPane(gp);
bp.setTop(sp);
b.setOnAction(e -> createLabel());
Your'e nearly there, all you now need to do is add the scroll pane as a child of whatever the container is
GridPane gp = new GridPane();
Button b = new Button("click");
gp.add(b, 1, 1);
b.setOnAction(e -> createLabel());
ScrollPane sp = new ScrollPane(gp);
container.add(sp); // where container is whatever node that'll contain the gridpane.
Play with this code
public class Controller {
#FXML private VBox topLevelContainer; // root fxml element
#FXML
void initialize(){
GridPane gridPane = new GridPane();
ScrollPane sp = new ScrollPane(gridPane);
topLevelContainer.getChildren().add(sp);
// add a 100 buttons to 0th column
for (int i = 0; i < 100; i++) {
gridPane.add(new Button("button"),0,i);
}
}
}
I have a JavaFX dialog, and it seems the content of the grid don't span the entire width of the dialog. Right now it spans to a MAXIMUM of the the left side of the dialog, to the width of the OK button. I'd like to either remove the white space to the right of my input fields. Or span the entire width.
I've tried:
Setting the min-width of the gridpane
Setting the min-width of the textfields
Setting the width of the stage
I'm pretty much at a loss here.
Here's my code!
// Create the custom dialog.
Dialog dialog = new Dialog<>();
dialog.initOwner(mainStage);
// Set Custom Icon
Stage stage = (Stage) dialog.getDialogPane().getScene().getWindow();
stage.getIcons().add(new Image(Constants.kApplicationIcon));
dialog.getDialogPane().getStylesheets().add(Constants.kRootStylesheet);
dialog.getDialogPane().getStyleClass().add("accountDialog");
dialog.setTitle("New User Detected");
dialog.setHeaderText("Please complete user registration!");
// Set the button types.
ButtonType loginButtonType = new ButtonType("Create Account", ButtonBar.ButtonData.OK_DONE);
dialog.getDialogPane().getButtonTypes().addAll(loginButtonType, ButtonType.CANCEL);
// Create the username and password labels and fields.
GridPane grid = new GridPane();
grid.setHgap(10);
grid.setVgap(10);
grid.setPadding(new Insets(20, 150, 10, 10));
grid.setAlignment(Pos.CENTER);
grid.setId("accountGrid");
TextField firstName = new TextField("First Name");
TextField lastName = new TextField("Last Name");
TextField email = new TextField("Email");
TextField gender = new TextField("Gender");
firstName.setId("textField");
lastName.setId("textField");
firstName.setPromptText("");
lastName.setPromptText("");
gender.setPromptText("");
email.setPromptText("");
email.setId("textField");
gender.setId("textField");
ToggleGroup studentRadioGroup = new ToggleGroup();
RadioButton mentorRadio = new RadioButton("Mentor");
RadioButton studentRadio = new RadioButton("Student");
studentRadio.fire();
mentorRadio.setToggleGroup(studentRadioGroup);
studentRadio.setToggleGroup(studentRadioGroup);
grid.add(new Label("First Name:"), 0, 0);
grid.add(firstName, 1, 0);
grid.add(new Label("Last Name:"), 0, 1);
grid.add(lastName, 1, 1);
grid.add(new Label("Email:"), 0, 2);
grid.add(email, 1, 2);
grid.add(new Label("Gender:"), 0, 3);
grid.add(gender, 1, 3);
GridPane.setHalignment(grid, HPos.CENTER);
GridPane.setHalignment(studentRadio, HPos.CENTER);
GridPane.setHalignment(studentRadio, HPos.CENTER);
grid.add(studentRadio, 0, 4);
grid.add(mentorRadio, 1, 4);
grid.setGridLinesVisible(true);
// Enable/Disable login button depending on whether a username was entered.
Node loginButton = dialog.getDialogPane().lookupButton(loginButtonType);
loginButton.setDisable(true);
// Do some validation (using the Java 8 lambda syntax).
firstName.textProperty().addListener((observable, oldValue, newValue) -> {
loginButton.setDisable(newValue.trim().isEmpty());
});
dialog.getDialogPane().setContent(grid);
// Request focus on the firstname field by default.
Platform.runLater(firstName::requestFocus);
Optional<ButtonType> result = dialog.showAndWait();
ArrayList<String> data = new ArrayList<>();
System.out.println(result.get().toString());
if (result.get().getButtonData() == ButtonBar.ButtonData.OK_DONE) {
data.add("TRUE");
data.add(firstName.getText());
data.add(lastName.getText());
data.add(email.getText());
data.add(gender.getText());
data.add(mentorRadio.isSelected() ? "TRUE" : "FALSE");
} else {
data.add("FALSE");
}
return data;
Here's an image of the result. I want to again; either remove all the whitespace to the right of my grid, or span my grid to fit the whole width.

You are creating that extra space with grid.setPadding(new Insets(20, 150, 10, 10));. That 150 is the right padding. See the Insets documentation.
The GridPane is resized to it's preferred size. The padding on the right of 150 prevents the TextFields from growing larger in this direction.
grid.setPadding(new Insets(20, 150, 10, 10)); // sets right padding to 150
If you want to grow the TextFields to the maximum size the Labels/RadioButton to the left leaves, you should use ColumnConstraints to specify, that the second column should always grow:
ColumnConstraints constraints = new ColumnConstraints();
constraints.setHgrow(Priority.ALWAYS);
grid.getColumnConstraints().addAll(new ColumnConstraints(), constraints);
It's also possible to specify the preferred width of the second column via the ColumnConstraints object.
To test the behaviour when the window size changes, you could make the dialog resizeable:
dialog.setResizable(true);
To see the area the GridPane covers it could be helpful to assign a background:
grid.setStyle("-fx-background-color: red;");
Have you tried the setExpandableContent() method from the dialog's pane? You can pass in whatever node you like, and then it should be able to resize to fit the entire Alert.
An example of setting a GridPane as the Alert's content.
GridPane() grid = new GridPane();
Alert alert = new Alert(AlertType.INFORMATION);
alert.getDialogPane().setExpandableContent(grid);

As you can see, Checkboxes are not aligned .Every component is created by code not from fxml...What can be the cause of this?
Edit:
First of all, width and height are fixed. Thus they will never change. I disabled Them Below you can find the code.

An HBox makes no guarantee about the amount of space it actually assigns to any child node that is contained inside it. It merely guarantees to place them in order, with a minimum gap if you specify a spacing, and makes a best effort to size each child node to its preferred size. Many factors which are beyond your control will affect the actual size of each node, including font sizes (which depend on the available fonts), total size available to the HBox, etc etc. All these may change depending on the platform the application is running on, including depending on the JDK version.
So trying to line things up vertically by placing them in a collection of HBoxs and setting the preferred sizes of the child nodes is simply not a reliable way to approach this (and is not designed as such). The problem is there is no real way to connect the layout of one HBox to the layout of another HBox: they are all laid out independently. If you want to lay components out so they are aligned relative to each other both horizontally and vertically, you should use a GridPane, which is specifically designed for that purpose.
It is generally a very bad idea (not just in JavaFX; this applies to most UI toolkits) to hard-code sizes of anything, so anytime you are using this as a solution, there is almost certainly a better approach.
The basic idea behind using a GridPane would look like:
GridPane grid = new GridPane();
// padding around entire grid:
grid.setPadding(new Insets(4);
grid.setHgap(10);
grid.setVgap(9);
Label nameLbl = new Label("Login Email");
// column 0, row 0:
grid.add(nameLbl, 0, 0);
txtEmail = new TextField();
txtEmail.focusedProperty().addListener((observable, oldValue, newValue) -> {
if(!newValue)
checkLicence();
});
// column 1, row 0, span 2 columns:
grid.add(txtEmail, 1, 0, 2, 1);
// ...
Label searchAssignedToMe = new Label("Search Replied to u");
// column 0, row 7:
grid.add(searchAssignedToMe, 0, 7);
cbSearchAssignedToMeTickets = new CheckBox();
cbSearchAssignedToMeTickets.setSelected(true);
// column 1, row 7, span two columns:
grid.add(cbSearchAssignedToMeTickets, 1, 7, 2, 1);
Label checkUpdateLbl = new Label("Check Updates");
// column 0, row 8:
grid.add(checkUpdateLbl, 0, 8);
cbCheckUpdates = new CheckBox();
cbCheckUpdates.setSelected(checkUpdatesSetting);
// column 1, row 8:
grid.add(cbCheckUpdates, 1, 8);
Button btnUpdateUpdater = new Button("Update Updater");
btnUpdateUpdater.setOnAction(event -> downloadUpdaterUpdate());
// column 2, row 8:
grid.add(btnUpdateUpdater, 2, 8);
// ...
Button btnSaveSettings = new Button("Save Settings");
btnSaveSettings.setOnAction(...);
// center button horizontally in its cells (it spans the whole row):
GridPane.setHalignment(btnSaveSettings, HPos.CENTER);
// column 0, row 9, span 3 columns:
grid.add(btnSaveSettings, 0, 9, 3, 1);
You can completely configure how any potential extra space is allocated among the columns (using ColumnConstraints instances), among the rows (using RowConstraints instances), and how the controls are aligned within their individual cell(s). You can also specify these on a node-by-node basis if you need.
You probably want, for example, hgrow of the three columns to be SOMETIMES, SOMETIMES, and ALWAYS; you may need to set the fillWidth of the TextInputControls to true.
See the GridPane documentation, which explains this all completely.
I am trying to create a UI in JavaFX which should have two columns and one row. The row should span from top to bottom (100% height) and the columns should be 80% and 20% wide respectively. In the first column, I am creating a textarea, while the second one has a sidebar with multiple buttons.
The problem I am facing is that the textarea is not getting full height. I can change the height in px, but I want to change in percentage. I tried adding RowConstraint, but it does not works. Any idea how should I proceed?
public void start(Stage primaryStage)
{
primaryStage.setTitle("Particles");
primaryStage.setResizable(false);
GridPane grid = new GridPane();
grid.setVgap(10);
grid.setHgap(10);
RowConstraints row1 = new RowConstraints();
row1.setPercentHeight(100);
ColumnConstraints column1 = new ColumnConstraints();
column1.setPercentWidth(80);
ColumnConstraints column2 = new ColumnConstraints();
column2.setPercentWidth(20);
TextArea environment = new TextArea();
grid.add(environment, 0, 0);
Button start = new Button("START");
HBox hbBtn = new HBox(10);
hbBtn.setAlignment(Pos.CENTER);
hbBtn.getChildren().add(start);
grid.add(hbBtn, 1, 0);
Scene scene = new Scene(grid, 725, 500);
primaryStage.setScene(scene);
primaryStage.show();
}
My Output:
You need to add the Vgrow Priority of the TextField as Always
GridPane.setVgrow(environment, Priority.ALWAYS);
In your code :
TextArea environment = new TextArea();
grid.add(environment, 0, 0);
GridPane.setVgrow(environment, Priority.ALWAYS);
Output:
I have created two Javafx Gridpanes and i want them to be in the same ligne, the second gridpane must be in the same ligne next to the first gridpane. Because i get one on the other when running.
This is my code:
Group root = new Group();
Scene scene = new Scene(root);
//creation du layout
layout = new GridPane();
layout.getColumnConstraints().add(new ColumnConstraints(350)); // column 1 is 350 wide
layout.getColumnConstraints().add(new ColumnConstraints(350));
layout.getColumnConstraints().add(new ColumnConstraints(350));
layout.setGridLinesVisible(true);
final Label source = new Label ("DRAG ");
layout.add(source, 0, 0);
final Label target = new Label ("DROP ");
layout.add(target, 1, 0);
layout2 = new GridPane();
layout2.getColumnConstraints().add(new ColumnConstraints(20)); // column 1 is 20 wide
layout2.setGridLinesVisible(true);
final Label source1 = new Label ("fire");
layout2.add(source1, 0, 4);
root.getChildren().addAll(layout,layout2);
If you want to add them next to each other, best choice would be to use HBox layout:
HBox hBox = new HBox();
//hBox.setSpacing(5.0);
//hBox.setPadding(new Insets(5,5,5,5));
hBox.getChildren().addAll(layout, layout2);
