Is it possible to display an 3D model outside (above) your Delphi form? Just like the MS agent plugin. Thnx a lot! |

Yes. With Delphi 6 and above every Form has two properties named "TransparentColor" and "TransparentColorValue". When you use the both properties and an Form with BorderStyle bsNone you can easily create an transparent window. You can combine it with OpenGL (i have try it  ). But it is terrible slow. Normally you should use the GDI.

When clicked on the transparent part of the window, does the window get the events or are they not captured bij the window, but go trough to windows below your invisible delphi form? Does anybody have experience with window clipping? |

Transparent parts of a window are usually created using Regions, and if you define them via regions, then yes, windows will handle clicks to transparent regions as if there was no window under that position. So if you have a transparent rect in your window and an icon on the desktop is visible through that hole, then clicking on that icon would work without further intervention from your side. |

I have seen that the property TranparentColor is using the function SetLayeredWindowAttributes (WIN-API). This function need at minimum windows 2000. If you want to use your Programm below then you should use regions. |

Thnx for your reactions. Is this window transparancy also available in an ActiveX form? Couldn't find it in the properties explorer. |
