I assume that this is what you would like to do, right?
The image is set as a background to the pnimage pane (B4J).
When you click on the "Show buttons" button the buttons are shown on the pane.
Clicking on one of the buttons (b0 to b5) will show which button is clicked.
You can use the "Remove buttons" to remove the buttons from the pnimage pane.
You can find the source code in the attachment (testenvironment103.zip)
You can also use labels in stead of the buttons.
If you want to use an imageview then put a transparent pnimage pane on top of the imageview.
