bgiSetGizmoNodeText

Sets the text of a specific node in a TreeView control. Searches gizmoMap for parentTreeview ID to get TreeView HWND. Searches treeviewNodes vector for gizmoNode ID to find the node's HTREEITEM handle and update the text field in the CTreeViewNode structure. If node found, calls UpdateTreeViewItemText helper function with parentHWND, hTargetNode, text, and node ID. Returns 0 in all cases (success returns 0, not 1). Returns -1 if TreeView not found (wait, code shows returns 0 for success, -1 only for missing TreeView).

This function updates the display text of an existing TreeView node. UpdateTreeViewItemText is a helper function that handles the Windows TreeView text update logic (likely using TVITEM with TVIF_TEXT mask and TVM_SETITEM message). The function updates both the visual TreeView control and the CTreeViewNode.text field in the tracking vector. Use for renaming nodes, reflecting data changes, or implementing edit operations. Note: Function signature shows return type Int, but implementation returns 0 on success, -1 if TreeView not found.
