I kept fuzzing around with binary trees and there is one thing I don''t get. I want to create a GUI for my game and want to access nodes, in my case windows (WND), and controls (Ctrl). Now, picture this tree: GAME / \ / \ WND WND / \ -------- -------- / | \ | \ Ctrl Ctrl Ctrl Ctrl Ctrl Am I right to presume that the windows would be the nodes and the controls are the childs? If so, are the windows called siblings? I''m a linguistic problem here :-) Thanks! ;-)

not sure if you''re talking about win32 programming, but from your diagram, the WND''s would be parents of the children, CTRL''s.

You said you wanted to access windows and controls, so just search down the tree for the node (they are all nodes) that you want.

That''s not a binary tree, binary trees only have two children (at most).

The WND are also called branch nodes, and the ctrl are leaf nodes, Game is the root node.
