Hi, src\iup_tree.c (line 661) Something is wrong with the iupTreeDragDropCopyCache function, should the id_src variable be a pointer? Because the attribution she receives is without effect.
/* compensate because we add space for new nodes */
if (id_src > id_dst)
id_src += count; // <== assigned a value that is never used.
regards,
Ranier Vilela
