GridPane in JavaFX

Question

I have some questions about grid pane. I have this Grid Pane . How to delete vertical line between first and second columns in the zero row? How to change colors and size of grid lines?

Answer 1

gridLines in GridPane are just for development purposes. They are not meant to be used in production. In http://docs.oracle.com/javafx/2/api/javafx/scene/layout/GridPane.html one can read:

gridLinesVisible - For debug purposes only: controls whether lines are displayed to show the gridpane's rows and columns.
