SceneEditor

Hi, need to create graphics editor with ability of adding images and arrange them by Z. Dragging, resizing etc. Images with alpha chanel. Can you advise to me the control or another they how i can render images to screen and if it control then how to get known is it clicked on the pixel where opacity more then zero to activate that image or if equals to zero then let the message go deeper into Z hierarchy. Thanks.

There are a few controls that you can try:
UCCDraw, UCCDiagram or with it's source codes E-XD++, at: http://www.code-home.com

Hope it is useful to you.
