DCTREEROOT

[Wolfgang Ciriack]

Hello,
i have an DCTREEROOT on a DCSTATIC, in the dialog i do an DC_ExpandTree(oTree) in the EVAL codeblock of DCREAD GUI.
Because there are alot of items, a vertical scrollbar is shown in the static and after the expand the last item is visible.
How can i manipulate the static, that the first item of the treeview is visible ?

Wolfgang -

Try this:

Code: Select all

oTannenbaum:setData(oTannenbaum:rootItem:getChildItems()[1])

[Wolfgang Ciriack]

That does not change anything.
Is there an Event i can post to the DCSTATIC that scrolls up to the beginning ?

It works in my DC_ExpandTree() function. I will need to see your code to see why it doesn't work for you.

Code: Select all

FUNCTION DC_ExpandTree( oTree, lExpand )

LOCAL i, aChildList, oTannenBaum := oTree

DEFAULT lExpand := .t.

IF IsMethod(oTannenBaum,'LOCKUPDATE')
  oTannenBaum:lockUpdate(.t.)
ENDIF

IF oTree:isDerivedfrom('XbpTreeView')
   oTree := oTree:rootItem
ENDIF

aChildList := oTree:getChildItems()

FOR i := 1 TO Len(aChildList)
  aChildList[i]:expand(lExpand)
  DC_ExpandTree( aChildList[i], lExpand )
NEXT

IF IsMethod(oTannenBaum,'LOCKUPDATE')
  oTannenBaum:lockUpdate(.f.)
ENDIF

IF IsMemberVar(oTannenbaum,'rootitem')
  oTannenbaum:setData(oTannenbaum:rootItem:getChildItems()[1])
ENDIF

RETURN nil

Does this work?:

Code: Select all

EVAL {|o| oDlg:=o, DC_ExpandTree(oTree), ;
              oTree:setData(oTree:rootItem:getChildItems()[1], ;
              CenterControl(o,M->oMainDlg), o:show() }

hi,

oTree:SetData() may set Focus to Item but it does not mean that it is visible.

i have look into my native Treeview and found this

Code: Select all

@Roger,
no this does not work, that is what i tried after your first posting.

@Jimmy,
i do not know how to integrate this.

I try to post a ready to compile example.

[rdonnay]

If you can give me some code that will compile and run, I will figure this out for you.

I can't compile the code you posted. It is missing functions.

[Auge_Ohr]

hi,

have try

Code: Select all

xxx := oTree:rootItem:getChildItems()[1] -> XbpTreeViewItem()
zzz := xxx:GethWnd() -> crash

so a XbpTreeViewItem() does not give me a Handle ...

but as Roger say

Code: Select all

 oTree:setdata(XbpTreeViewItem) 

must work
