As far as I know a background image inside a treegadget is not possible. Then you have to use windows api for get it done, but I have no experience with this.

oryaaaaa posted this code example to display a TreeGadget with an image as background in 2004 (and updated his example more recently for PB 5.20+).

You have to add your own picture by replacing

Code: Select all

  LoadImage(0, "c:\body.bmp")

by (for example)

Code: Select all

  LoadImage(0, #PB_Compiler_Home + "Examples\3D\Data\Textures\Clouds.jpg")

and adding

Code: Select all

UseJPEGImageDecoder()

to the top of the code in order to try it (tested successfully on Windows XP SP3 and Windows 7 x86 SP1).
