Here is an image:

Here is the code:

int charSpacing = 1;
int charsInWid         


        

Answer 1

• You can use this GridPane.setHalignment(tmp[currArrPos], HPos.CENTER); Using GridPane to layout controls

Answer 2

oh, that was easy. i did the alignment on the wrong place. adding this will do the job:

tmp[currArrPos].setAlignment(Pos.CENTER);

thanks anyway.

Answer 3

You can use the setAligment(Pos.CENTER) property of your element-

or you can define a contraint to the GridPane that contains the elements

<columnConstraints>
    <ColumnConstraints halignment="CENTER" />
</columnConstraints>

Example:

<?import javafx.geometry.Insets?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.ColumnConstraints?>

<GridPane fx:controller="app.graphics.Controller"
          xmlns:fx="http://javafx.com/fxml" alignment="center" hgap="10" vgap="10">
    <columnConstraints>
        <ColumnConstraints halignment="CENTER" />
    </columnConstraints>
</GridPane>
