Cześć Marku.
Niestety nie robiłem tego dla drzewa. Mam problem z określeniem id elementu drzewa, na którym znajduje się wskaźnik myszy w momencie rozpoczęcia przeciągania i upuszczenia (wiersz 414 i 528 w DragAndDrop.prg). Zwracana jest pozycja aktualnie wybranego elementu. 😒
Gdyby udało się to jakoś określić, dalej byłoby już "z górki". ;)
Chyba bez C się nie obejdzie, ale ja jestem "za cienki".

Na razie mam nawał innej roboty - początek roku ;) no i klient jeszcze nie wymyślił, żeby przeciągać gałązki drzewa :) :)
Ale jak się odrobię, to popatrzę, czy w jakimś stopniu da się to zaadoptować do drzewa.

Pozdrawiam, Marek

Hi Marek. Just as I thought without C, it would not work.
I have made the TreeView_HitTest function, it returns the value of the handle of the tree node/item on which the mouse pointer is located. :geek:
In the attachment you have a sample using DragAndDrop on trees. You can move nodes/items within a given tree or drag from tree #1 to tree #2.
What I lack in using a tree is the insertion method "InsertItem" ;) .
The "AddItem" method adds items at the end of the node. To simulate the insert method, you would have to save the node structure, insert the item in the saved structure in the right place, delete the node and add item by item in its place. :idea:
