I've problem with the TreeView component, It has the CheckBoxTreeItem to check enable or disable, it's very select and unselect with this reference ==> Using JavaFX UI Controls: Tree View | JavaFX 2 Tutorials and Documentation with Using Tree Cell Editors.
This is the image with the tree view have CheckBoxTreeItem
(http://docs.oracle.com/javafx/2/ui_controls/img/tree-view-checkbox1.png)
At now, I want to add the icon image beside the CheckBoxTreeItem (Its mean that we have the icon image beside the checkbox).
Could anyone help me this problem?
I saw that when I set like that
tree.setCellFactory(CheckBoxTreeCell.forTreeView());
==> It can not show the icon
This is my coding
package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Node;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.CheckBoxTreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.control.cell.CheckBoxTreeCell;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
primaryStage.setTitle("Tree View Sample");
Node graphic = new ImageView(new Image("https://duke.kenai.com/iconSized/duke4.gif"));
CheckBoxTreeItem<String> rootItem =
new CheckBoxTreeItem<String>("View Source Files", graphic);
rootItem.setExpanded(true);
final TreeView tree = new TreeView(rootItem);
tree.setEditable(true);
tree.setCellFactory(CheckBoxTreeCell.<String>forTreeView());
for (int i = 0; i < 8; i++) {
final CheckBoxTreeItem<String> checkBoxTreeItem =
new CheckBoxTreeItem<String>("Sample" + (i+1), graphic);
rootItem.getChildren().add(checkBoxTreeItem);
}
tree.setRoot(rootItem);
tree.setShowRoot(true);
StackPane root = new StackPane();
root.getChildren().add(tree);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Thanks 4 your reading.

I did it and you should refer in that page ==> https://forums.oracle.com/message/11232268#11232268
CheckBoxTreeItem have a one object property we cannot use more than one object within it.
try this..
CheckBoxTreeItem<ImageView> chkbobj;
ImageView mv = new ImageView();
mv.setImage(new Image(getClass().getResourceStreamAs("abc.png")));
chkboobj.setGraphic(mv);

I want to place a vertical (90 degree rotated) Label on the left side of a HBox. A grid pane shall fill out the entire remaining space. If I decrease the with of the rotated label to reduce its requirred horizontal space, the text length is shrinked. Otherwise if i reduce the Height manually, nothing happens.
How can i reduce the used with of the rotated Label?
Using Scenebuilder and Windows 7.
Rotate the Label and wrap it in a Group. The layout bounds of the group will be computed after applying the transformation to the label:
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class RotatedLabelTest extends Application {
#Override
public void start(Stage primaryStage) {
Label hello = new Label("Hello");
Label world = new Label("World");
hello.setRotate(90);
world.setRotate(90);
HBox root = new HBox(5, new Group(hello), new Group(world));
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
I need to display one or more stage(s) within a TabPane by clicking on a button, such as the picture below
My target is to have a situation similar to JInternalFrame in Swing: how to accomplish this?
I am not able to add stage as children to the tab pane.
If this is not possible, what could be other solutions? I would like to have SplitPanes on the stage.
Thanks
PS I am using Win7, NetBeans 7.4 Beta (Build 201307092200), SceneBuilder 1.1
Edit: here is how it looks after some VFXWindows css changes
There's one thing worth notice: I have had to add a node ( in my case an HBox with prefSize(0,0), otherwise I can't move o resize the first window plotted, only the first one.
As last, I can't find a way to set windows full screen (maximize).
Here I put an example of windows from jfxtras inside of Tabs, I just modify the example.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.stage.Stage;
import jfxtras.labs.scene.control.window.CloseIcon;
import jfxtras.labs.scene.control.window.MinimizeIcon;
import jfxtras.labs.scene.control.window.Window;
public class WindowInTab extends Application {
private static int counter = 1;
private void init(Stage primaryStage) {
TabPane tabPane = new TabPane();
Tab tab = generateTab("Windows...");
Tab anotherTab = generateTab("More Windows");
tabPane.getTabs().addAll(tab, anotherTab);
primaryStage.setResizable(true);
primaryStage.setScene(new Scene(tabPane, 600, 500));
}
private Tab generateTab(String tabName) {
Tab tab = new Tab(tabName);
final Group root = new Group();
tab.setContent(root);
Button button = new Button("Add more windows");
root.getChildren().addAll(button);
button.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent arg0) {
// create a window with title "My Window"
Window w = new Window("My Window#"+counter);
// set the window position to 10,10 (coordinates inside canvas)
w.setLayoutX(10);
w.setLayoutY(10);
// define the initial window size
w.setPrefSize(300, 200);
// either to the left
w.getLeftIcons().add(new CloseIcon(w));
// .. or to the right
w.getRightIcons().add(new MinimizeIcon(w));
// add some content
w.getContentPane().getChildren().add(new Label("Content... \nof the window#"+counter++));
// add the window to the canvas
root.getChildren().add(w);
}
});
return tab;
}
public double getSampleWidth() {return 600;}
public double getSampleHeight() {return 500;}
#Override
public void start(Stage primaryStage) throws Exception {
init(primaryStage);
primaryStage.show();

I don't know if this was exactly what you were looking for. Hope it helps!
Can someone please give me an example on how to center text on a JavaFX 2 Canvas?
GraphicsContext has some functions like setTextAlign, but I am not sure on how to use all those methods and which of them I really need. I want to center my text vertically and horizontally.
Set the text align to center.
Set the text baseline to center.
Draw the text in the center of your canvas (by positioning it at half the canvas width and height).
Here is a sample:
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.geometry.VPos;
import javafx.scene.*;
import javafx.scene.canvas.*;
import javafx.scene.layout.StackPane;
import javafx.scene.text.TextAlignment;
import javafx.stage.Stage;
public class TextCanvas extends Application {
#Override public void start(Stage primaryStage) {
Canvas canvas = new Canvas(175, 40);
GraphicsContext gc = canvas.getGraphicsContext2D();
gc.setTextAlign(TextAlignment.CENTER);
gc.setTextBaseline(VPos.CENTER);
gc.fillText(
"Text centered on your Canvas",
Math.round(canvas.getWidth() / 2),
Math.round(canvas.getHeight() / 2)
);
StackPane layout = new StackPane();
layout.getChildren().addAll(canvas);
primaryStage.setScene(new Scene(layout));
primaryStage.show();
}
public static void main(String[] args) { launch(args); }
}
you wanna use
control.setAlignment(Pos.CENTER); and
control.setStyle("-fx-alignment: CENTER;");
see here for some downloadable sample code of this in action.
how to spin line (rotating 360 degree) in java fx? here the code :
package javafxapplication1;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Ellipse;
import javafx.scene.shape.EllipseBuilder;
import javafx.scene.shape.LineTo;
import javafx.scene.shape.MoveTo;
import javafx.scene.shape.Path;
import javafx.stage.Stage;
import javafx.scene.transform.Transform;
public class JavaFXApplication1 extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
Group root = new Group();
Scene scene = new Scene(root, 800, 600, Color.WHITE);
Ellipse lingkaran = EllipseBuilder.create()
.centerX(400)
.centerY(300)
.radiusX(210)
.radiusY(210)
.strokeWidth(3)
.stroke(Color.BLACK)
.fill(Color.WHITE)
.build();
Path path = new Path();
MoveTo moveTo = new MoveTo();
moveTo.setX(400);
moveTo.setY(300);
LineTo lineTo = new LineTo();
lineTo.setX(400);
lineTo.setY(100);
path.getElements().add(moveTo);
path.getElements().add(lineTo);
path.setStrokeWidth(5);
path.setStroke(Color.BLACK);
root.getChildren().add(lingkaran);
root.getChildren().add(path);
primaryStage.setScene(scene);
primaryStage.show();
}
}
i want to spin the line 360 degree, but i don't know how to do it. I have been looking for this in google but i never found the solution. Can somebody help me please?
You could rotate your circle and line with:
root.getChildren().add(lingkaran);
root.getChildren().add(path);
RotateTransition rot = RotateTransitionBuilder.create().node(root)
.byAngle(360).duration(new Duration(3000)).build();
rot.play();
primaryStage.setScene(scene);
primaryStage.show();
If you want to rotate only the line, replace .node(root) with .node(path).. If you don't want to use an animation you may set the rotation property of the line.
I have a Pane (test_) as the center child of a border pane. The child fills its area and grows when the window is stretched as expected.
Now I scale test_. Normally it would be centered in its area, but I don't want that, so I translate it back to the upper-left corner of its area.
But now when I stretch the widow it pulls test_ away from the upper-left corner of its area. Can anyone explain why this happens? The sample below incorporates a slider that scale's test_.
Thank you.

test_.setTranslateY( (scale * height - height) / 2 );
}

The reason your solution goes awry when the Scene is resized is because Panes are resizable nodes, so the layoutbounds of the Pane is changing as the Pane is being resized, but you aren't taking that into account in your translation calculations.
The following directly uses Scale and Translate transforms to avoid any resizing related issues. Does this sample code do what you want?

// make the test pane background a different color if you want to see the extent of the pane.

// create some text content to place in the test pane.
Text text = new Text("Upper left corner");
text.setStyle("-fx-font-size: 30px;");
text.setFill(Color.WHITE);
text.setTextOrigin(VPos.TOP);
testPane.getChildren().add(text);
Scale scaleTransform = new Scale();
testPane.getTransforms().addAll(scaleTransform, new Translate(0, 0));
// slider to scale the test pane.
final Slider scaler = new Slider(.25, 3, 1);
scaleTransform.xProperty().bind(scaler.valueProperty());
scaleTransform.yProperty().bind(scaler.valueProperty());
// stackpane added to pad out empty space when testPane is scaled small.
// stackpane also clips the zoomed content when it gets larger than it's standard layout.
final StackPane stack = new StackPane();
stack.getChildren().addAll(testPane);
StackPane.setAlignment(testPane, Pos.TOP_LEFT);
stack.setStyle("-fx-background-color: blue;");
final Rectangle clip = new Rectangle();
testPane.layoutBoundsProperty().addListener(new ChangeListener<Bounds>() {
#Override public void changed(ObservableValue<? extends Bounds> observable, Bounds oldBounds, Bounds bounds) {
clip.setWidth(bounds.getWidth());
clip.setHeight(bounds.getHeight());
}
});
stack.setClip(clip);
// layout everything.
VBox layout = new VBox();
layout.setPrefSize(250, 250);
layout.getChildren().setAll(stack, scaler);
VBox.setVgrow(stack, Priority.ALWAYS);
// show the stage.
stage.setScene(new Scene(layout));
stage.show();
