Get width / height of a GridPane column / row?

While it's obvious how to set the width/height of a column/row in a GridPane, how can I actually query these values?

In javafx-8 there now is a method called GridPane#impl_getCellBounds which will do the trick, although it is part of the internal API. (Not sure if this was also available in javafx-2)

Note, as commented by @olmstov the mentioned method is depricated and removed in later versions of javafx. If there is a better way (compatible with the public API) it is recommended to use that instead of this alternative.

Disclaimer: I extracted this from the question, where OP (stefan.at.wpf) self-answered it. Answers should not be contained in the question itself. Also don't use Edit/Update: Questions/Anwers don't need to record history.

One can add an empty HBox/VBox to the corresponding GridPane column/row and attach listeners to the HBox/VBox widthProperty/heightProperty, still I am wondering if there is a way to directly get the width and height of a column / row in a GridPane.

JavaFX8: There is a pack protected method GridPane.getGrid to get the current row/col sizes in a two dim double array.You could use reflection to acccess it. In environments with a security mgr, this won't work.

public double[][] getCurrentGrid(GridPane gp) {
    double[][] ret=new double [0][0];

    try {
        Method m=gp.getClass().getDeclaredMethod("getGrid");
        m.setAccessible(true);
        ret=(double[][])m.invoke(gp);                   

    } catch (Exception e) {
        e.printStackTrace();
    }

    return ret;
}
