How to use the layout's method setEffect properly

Question

My easy application has two layout panes. First is VBox pane. It is root node. Second pane is child pane (Pane layout). I want to use DropShadow effect for root pane only. I do it according to the documentation . Unfortunately I have the Drop shadow effect for both panes. For root and for child. Is it a bug or there is a way to set it for one pane only? I was trying to use pane.setEffect( null ) but without success. When I add some child to pane, the new node has shadow also.

I use JavaFX8 (Windows 7 - 64).

Thank you.

public void start( Stage stage )
{
        VBox vbox = new VBox();
        vbox.setPadding( new Insets( 30 ) );

        BorderStrokeStyle style = new BorderStrokeStyle( StrokeType.INSIDE, StrokeLineJoin.MITER, StrokeLineCap.BUTT, 10, 0, null );
        BorderStroke stroke = new BorderStroke( Color.BLUE, style, CornerRadii.EMPTY, new BorderWidths( 1 ), null );
        vbox.setBorder( new Border( stroke ) );

        DropShadow dropShadow = new DropShadow();
        dropShadow.setOffsetX( 10 );
        dropShadow.setOffsetY( 10 );
        vbox.setEffect( dropShadow );

        Pane pane = new Pane();
        pane.setBorder( new Border( stroke ) );

        pane.setPrefWidth( 500 );
        pane.setPrefHeight( 500 );

        vbox.getChildren().add( pane );

        stage.setScene( new Scene( vbox ) );
        stage.show();
}

addition:

Was trying to use css: vbox.setStyle( "-fx-effect: dropshadow(gaussian, gray, 10, 0.6, 10, 10);" ); The same shit - the effect was applied for both panes. ((

Have you tried setting the effect of the child pane with `pane.setEffect( null );`? — Matt C, Apr 25 '16 at 15:03

Here I am trying to answer to my own question.

I made some easy investigations and It looks like it is not a bug. It is an attempt to provide a real life behavior for a pane.

If a pane doesn't have non-transparent background - the all pane's children should have a shadow also (if the owner pane has it). On the other hand - if the pane has solid background, the children can't have a shadow. Till you put shadow specially.

So... You just need to provide a non-transparent background for pane, to avoid shadows for pane's children shapes and panes.

Sure, It would be good to notice it in the docemtntation.
