Hi,
Yes, it is exactly like this. It is just an optimization since the icon node is just an image with an label - one on top or left of the other. Therefore I've used the vertical/horizontal flow layout in the IconNodeWidget by default. I have updated the javadoc and documentation.
Sorry for inconvenience, David

Rajan,
I believe you were correct in assuming that the AbsoluteLayout was set by default. However, it seems to be different in IconNodeWidget (assuming this is what you are using). By default it uses the VerticalFlowLayout unless specified by the overloaded constructor.
Regards, Joelle

I had wanted pins in specific locations and had tried the setPreferredLocation method, however that did not work. After seeing your email I decided to explicitly set the layout to Absolute and it worked! For some reason I had assumed that the layout was by default set to Absolute.
Thanks for the pointer. Rajan

You can set the a layout for any widget. This might be a good place to start. http://www.netbeans.org/download/dev/javadoc/org-netbeans-api-visual/org/netbeans/api/visual/widget/doc-files/documentation.html#Layout
It sounds like you are using IconWidget as the Nodes. So you would just set the IconWidget's layout as show below. If you end having control over the constructor of the Widget, you can also set the layout there. Then when you add any children ie pin widgets of some sort) to that node widget they should fall into you desired layout. Widget w1 = new Widget (scene); w1.setBorder (BorderFactory.createLineBorder (1, Color.RED)); w1.setLayout (LayoutFactory.createVerticalFlowLayout ());
Remember, if you decide to play the pins in very specific location (ie you don't want to use one of the predefined layouts ), you can simply set the preferred location rather than modifying the layout.

Hi,
I have been able to try some stuff using GraphPinScene and add Pins etc. to an IconWidget. My problem is that I need to place the pins (they are images) in certain locations on the IconWidget. Anytime I add pins it gets placed in the same location. Could someone guide me to the best way to place pins in arbitrary locations on a widget? Thanks Rajan
