Neither the online or offline Manuels are of any helps when it comes to Tree using the GUI...

so I create this:
MainMoTree = CreateTreeView( 2,2,170,347,MainTab1 )
but after I tryed many things but how do you add stuffs?

Could I have an example please? with a bunch of stuff in it?

I would recommend reading Microsofts' Windows API references on Common Controls. You'll find a lot more information there that is similar enough to get you going. I'm not sure where you would find them ("I" have books at home on the subject PLUS I have Visual C++) but you could try MS's website?

This is code from the BlitzPlus samples folder (Samples->Mak->simple_treeview.bb) which will hopefully get you started:

window=CreateWindow( "Simple TreeView demo",0,0,640,480 )

treeview=CreateTreeView( 0,0,ClientWidth(window),ClientHeight(window),window )
SetGadgetLayout treeview,1,1,1,1

root=TreeViewRoot( treeview )

hello=AddTreeViewNode( "Hello!",root )
	test1=AddTreeViewNode( "Test1",hello )
	test2=AddTreeViewNode( "Test2",hello )
	test3=AddTreeViewNode( "Test3",hello )
	test4=AddTreeViewNode( "Test4",hello )
		test5=AddTreeViewNode( "Test5",test4 )
		test6=AddTreeViewNode( "Test6",test4 )
		test7=AddTreeViewNode( "Test7",test4 )
		
While WaitEvent()<>$803

	If EventID()=$401 And EventSource()=treeview
		Select SelectedTreeViewNode( treeview )
		Case hello Notify "Hello hit"
		Case test1 Notify "Test1 hit"
		Case test2 Notify "Test2 hit"
		Case test3 Notify "Test3 hit"
		Case test4 Notify "Test4 hit"
		Case test5 Notify "Test5 hit"
		Case test6 Notify "Test6 hit"
		Case test7 Notify "Test7 hit"
		End Select
	EndIf

Why doesnt it show you the little + when u start the program?
Is it possible to unfold them when program starts?

Users would then probably ask "Why do nodes start out as expanded?":)

Simply add an "ExpandTreeViewNode hello" at the end of the construction.

Because other user wanted it expended as default XD

Whether or not you hate them has nothing to do with where the documentation is so do yourself a favor and read it.

Found this link: http://www.developerfusion.com/show/77

Like I said before, it's all similar. Just reading through it should help you enough to give you ideas and point you in the right direction.
