delphi - How to update the VirtualStringTree scrollbars? -


i having hardtime fix problem on virtualstringtree.

i have nodedata has having same node.nodeheight or defaultnodeheight, problem im going change each of nodeheight different size result virtualstringtree did not give me correct scrolling causing other node cannot seen.

anyone help?

thats because vt won't know total height of tree until nodes initialized (theyr height becomes known). 1 option force nodes initialized. thats of course against "virtual paradigm" of th vt, if have small number of nodes it's not bad. option set defaultnodeheight maximum nodeheight going use (if know beforehand) vt assume uninitialized nodes of height.
