I'm using the TCustomTreeView.OnCustomDrawItem event to change the color of the nodes of a TTreeview, but now i need to replace the image used to expand and collapse the nodes, but i'm stuck with this. How i can replace the images of a Treeview used to expand a collapse a node?
A standard TTreeView component does not allow you to replace the expand/collapse images, either directly or via owner-drawing. You will have to find a third-party TreeView component that supports it.
