VirtualTreeView: Zugriff auf einzelnen Node

Aber wie kann ich denn die kompletten Node in der VST durchlaufen

IterateSubtree geht sehr gut dazu
brauchst nur eine callback funktion schreiben.

Delphi-Quellcode:

function TBaseVirtualTree.IterateSubtree(Node: PVirtualNode; Callback: TVTGetNodeProc; Data: Pointer;
  Filter: TVirtualNodeStates = []; DoInit: Boolean = False; ChildNodesOnly: Boolean = False): PVirtualNode;

// Iterates through the all children and grandchildren etc. of Node (or the entire tree if Node = nil)
// and calls for each node the provided callback method (which must not be empty).
// Filter determines which nodes to consider (an empty set denotes all nodes).
// If DoInit is True then nodes which aren't initialized yet will be initialized.
// Note: During execution of the callback the application can set Abort to True. In this case the iteration is stopped
//       and the last accessed node (the one on which the callback set Abort to True) is returned to the caller.
//       Otherwise (no abort) nil is returned.

Callback:

Delphi-Quellcode:

procedure(Sender: TBaseVirtualTree; Node: PVirtualNode; Data: Pointer; var Abort: Boolean) of object;

Super vielen Dank, funzt!

Hab die Function von M. Hassmann genommen, läuft prima!^^
