Setting treeview background color in VB6 has a flaw - help?
- by RenMan
I have successfully implemented this method of using the Win32 API to set the background color of a treeview in VB 6: http://support.microsoft.com/kb/178491
However, one thing goes wrong: when you expand the tree nodes more than two levels deep, the area to the left of (and sometimes under) the inner plus [+] and minus [-] signs is still white.
Does anyone know how to get this area to the correct background color, too?
Note: I'm also setting the BackColor of each node, and also the BackColor of the treeview's imagelist.
Here's my version of the code:
Public Sub TreeView_SetBackgroundColor(TreeView As MSComctlLib.TreeView, BackgroundColor As Long)
Dim lStyle As Long, Node As MSComctlLib.Node
For Each Node In TreeView.Nodes
Node.BackColor = BackgroundColor
Next
TreeView.ImageList.BackColor = BackgroundColor
Call SendMessage( _
TreeView.hwnd, _
TVM_SETBKCOLOR, _
0, _
ByVal BackgroundColor)
'Now reset the style so that the tree lines appear properly.
lStyle = GetWindowLong(TreeView.hwnd, GWL_STYLE)
Call SetWindowLong(TreeView.hwnd, GWL_STYLE, lStyle - TVS_HASLINES)
Call SetWindowLong(TreeView.hwnd, GWL_STYLE, lStyle)
End Sub
