Bei der normalen TreeView-Komponente war es einfach: Es gab direkt eine Routine (AddText), womit man die Nodes sofort beim Hinzufügen beschriften konnte. So einfach ist es beim VirtualTree nicht. Aber dafür geht das Hinzufügen viel schneller. Dieses Kapitel basiert größtenteils aus dem vorherigen Kapitel. Dem Node wird ebenfalls ein Record hinzugefügt. Die Variable FCaption des Records benutzen wir für die Beschriftung Der Record ist jetzt mit Daten gefüllt. Diese Daten ‚gehören' jetzt zu dem Node. Jetzt gibt es aber noch einige Fallstricke, die zu beachten sind. Die Größe der Struktur muss dem Tree bekannt sein. Die macht man durch die Zuweisung: VST.NodeDataSize := SizeOf(TTreeData); Diese Zuweisung muss in der Regel nur einmal gesetzt werden. Verwendet man allerdings anders aufgebaut Daten muss der Werte aktualisiert werden. Alternativ kann man auch das Ereignis OnGetNodeDataSize benutzen.
