I have noticed a strange behaviour concerning rotated texts (Label,...) in JavaFx...

Originally, I just wanted to be able to display Labels vertically in a GridPane. The first problem is that there is no simple way to tell a Label to display its content in a given direction/orientation. It would be nice to have something like the Side property of the tabPane which would allow to easily turn the text around...

Anyway, I then resigned myself to use the Rotate function to turn my Label. That is when the strange thing began to occur...I am putting my Label in a grid cell which would not be large enough to display the full text if it is not rotated but the text should be able to fit once rotated. The problem is that the text appears wrapped even when it is rotated as if the wrapping test were done before the text is actually rotated... The problem can be seen on this screenshot http://hpics.li/e210f2f : the text that should be displayed is written in the Tooltip and we can see that only the first letter of the rotated text is displayed in the cell grid even though there is more than enough space to display it all...

The following code shows the issue as well as a workaround which consists in putting Label in a Group and rotation the Group rather than the Label :

import javafx.application.Application;
import javafx.geometry.HPos;
import javafx.geometry.VPos;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Control;
import javafx.scene.control.Label;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.scene.layout.RowConstraints;
import javafx.stage.Stage;
public class RotatedLabelsInGrid extends Application
{
@Override
public void start(Stage primaryStage)
{
final GridPane root = new GridPane();
root.setGridLinesVisible(true);
      
final Label lbl1 = new Label("example1") ;
final Label lbl2 = new Label("example2") ;
final Label lbl3 = new Label("example3") ;
final Label lbl4 = new Label("example4") ;
final Label lbl5 = new Label("example5") ;
Group group = new Group(lbl5);

lbl1.setRotate(-90.0d);
lbl2.setRotate(-90.0d);
lbl3.setRotate(-90.0d);
lbl4.setRotate(-90.0d);
group.setRotate(-90.0d);

lbl1.setStyle("-fx-border-color: red;");
group.setStyle("-fx-border-color: blue;");


root.add(lbl1, 0, 0);
root.add(lbl2, 1, 0);
root.add(lbl3, 2, 0);
root.add(lbl4, 3, 0);
root.add(group, 4, 0);

final ColumnConstraints colConstraints = new ColumnConstraints(20, 20, Double.MAX_VALUE, Priority.ALWAYS, HPos.CENTER, true);
for( int index = 0; index < 5; index++)
{
root.getColumnConstraints().add(colConstraints);
}

final RowConstraints rowConstraints = new RowConstraints(Control.USE_COMPUTED_SIZE, Control.USE_COMPUTED_SIZE, Control.USE_COMPUTED_SIZE, Priority.ALWAYS, VPos.CENTER, true);
root.getRowConstraints().add(rowConstraints);


final Scene scene = new Scene(root, 20, 200);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args)
{
launch(args);
}
}
