javafx：为GridPane中的标签设置不同的节点方向

Question

I have a GridPane and I want one label to span from left to right , while the other label to span from right to left . However, I just cannot get this working. I can set node orientation for the GridPane itself but not for the individual labels.

This is what I have so far:

GridPane gridPane = new GridPane();
...
// upper left corner of grid pane
Label label1 = new Label("left to right");
label1.setNodeOrientation(NodeOrientation.RIGHT_TO_LEFT);
gridPane.add(label1, 0, 0,7,1);

// bottom right corner of grid pane
Label label2 = new Label("right to left");
label2.setNodeOrientation(NodeOrientation.LEFT_TO_RIGHT);
gridPane.add(label2, 2, 9,8,1);

UPDATE: Since GridPane default node orientation is from left to right, label1 is actually fine. Problem is with my label2. I want it to span from right to left such that regardless of the length of the text, it always starts at the bottom rightmost corner.

An ideal example (3 X 10) would be:

|Label1          |
|                |
|          Label2|

Ideally, if Label2 span the grids from right to left and if the length of the text in the label increases, it would look like this:

|Label1          |
|                |
|      Label2Long|

But right now, what I am getting is this:

|Label1          |
|                |
|  Label2Long    |     <- I want to get rid of the space between the label and the right border

Answer 1

nodeOrientation has nothing to do with alignment, which is what you really want here.

I think you want

GridPane.setHalignment(label2, HPos.RIGHT);

The Javadocs for GridPane describe how to use all these settings in a lot of detail.
