Ich bin mir sehr sicher das das der ein oder andere gebrauchen kann.
Hoffe haben sich keine Fehler eingeschlichen.

Ändert das Icon eines Eintrags im TreeGadget, anhand eines geladenen Icons.

Code: Alles auswählen

Schau Unten!

Funktioniert das auch mit Sub-Items?
Also zum Bsp.:

Code: Alles auswählen

[+] Item 1
  - Sub Item 1_1
  - Sub Item 1_2
[+] Item 2
  - Sub Item 2_1
  - Sub Item 2_2

Das hab ich jetzt garnicht getestet,
aber ansich dürfte es auch funktionieren,
müßte ich erstmal sehen wie PureBasic da die ImageList verwaltet.
