Parameter	Mode	Type	Default	Description
x	In	Int32	required	Horizontal position inside the group.
y	In	Int32	required	Vertical position inside the group.
width	In	Int32	required	Width of the tree.
height	In	Int32	required	Height of the tree.
group	In	Int32	required	Window, panel, tabber or canvas that holds it.
style	In	Int32	0	0, or 65536 to not follow the group when it is resized. Defaults to 0.

Description

Makes a list of nodes that can be opened and closed, like a folder view. Clicking a node sends $401 with the tree as the source, and SelectedTreeViewNode tells which. The tree starts out empty: add nodes below the node that TreeViewRoot gives.

Examples

Graphics 320, 240, 32, 2
win  = CreateWindow("Tree", 10, 10, 300, 200, Desktop(), 3)
tree = CreateTreeView(10, 10, 270, 140, win)
fruit = AddTreeViewNode("Fruit", TreeViewRoot(tree))
AddTreeViewNode "Apple", fruit
AddTreeViewNode "Pear", fruit
Repeat
	e = WaitEvent()
	If e = $401 Then SetGadgetText win, "Node " + TreeViewNodeText(SelectedTreeViewNode(tree))
Until e = $803
