Create gridPane in Javafx - javafx-2

Question

I'm new in JavaFx, i have two gridPane created in FXMl, i want to do the same thing but in Javafx.
I want to create class that extends GridPane, so when i call my class i will have the same result that i have in fxml
PS:if you are using sceneBuiler, check Grid Lines visible so you can see all GridPane
thank you
<GridPane layoutX="138.0" layoutY="72.0">
<children>
<Label text="01" GridPane.columnIndex="1" GridPane.rowIndex="0" />
<Label text="01" GridPane.columnIndex="2" GridPane.rowIndex="0" />
<Label text="01" GridPane.columnIndex="3" GridPane.rowIndex="0" />
<Label text="01" GridPane.columnIndex="4" GridPane.rowIndex="0" />
<Label text="01" GridPane.columnIndex="0" GridPane.rowIndex="0" />
</children>

Answer 1

Here is a routine I used to create a GridPane x by y and add it in a parent Pane called grille (This pane is created by FXML)
public GridPane DessineGrille(int x, int y) {
((Pane) Main.root.lookup("#grille")).getChildren().clear();
GridPane gp = new GridPane();
x += 2;
ColumnConstraints column = new ColumnConstraints();
column.setPercentWidth((1.0f/((float) x))*100.0f);
for (int i = 1; i <= x; i++) {
gp.getColumnConstraints().add(column);
}
y += 2;
RowConstraints line = new RowConstraints();
line.setPercentHeight((1.0f/((float) y))*100.0f);
for (int i = 1; i <= y; i++) {
gp.getRowConstraints().add(line);
}
gp.setGridLinesVisible(true);
gp.setHgap(10);
gp.setVgap(10);
Light.Distant light = new Light.Distant();
light.setAzimuth(-135.0);
Lighting lighting = new Lighting();
lighting.setLight(light);
lighting.setSurfaceScale(5.0);
gp.setEffect(lighting);
gp.setMinSize(((Pane) Main.root.lookup("#grille")).getWidth(), ((Pane) Main.root.lookup("#grille")).getHeight());
((Pane) Main.root.lookup("#grille")).getChildren().add(gp);
return gp;
}
To help you, in french 'dessine' means draw and 'grille' menas grid (I don't want to introduce error just by translating).
Does it help?
