I am struggling in merging GUITreeViewEx, Shelltristate and enhancing to handle a third state that means : some items under are selected.
I have difficulties handling expand order and key Space (especially when node is collapsed).
Here the zip with UDF and and example.
The problem I might need some advice to handle :
1- When load Treeview, have a correct settings of the checkbox for a tristate tree
2 - Handle keyboard used for walking in tree
