ControlID

[JusGellin]

This is probably so obvious, but what does it mean when using -1 for the controlID? It seems like it refers back to the create function handle, but I didn't see anything mentioned explicitly in the Help files other than "The control identifier (controlID) as returned by a GUICtrlCreate... function."

e.g.

$generalitem    = GUICtrlCreateTreeViewitem("General", $treeview)
GUICtrlSetColor(-1, 0x0000C0)

Thanks

Using -1 as the control ID, uses the ID of the previously created Control.

For example, in this case the function GUICtrlSetColor will use the controlID of $generalitem_2

$generalitem= GUICtrlCreateTreeViewitem("General", $treeview)
$generalitem_2= GUICtrlCreateTreeViewitem("General", $treeview)
GUICtrlSetColor(-1, 0x0000C0)

I kind of thought so. Is saying this is a handle to the control the same as the ID?

No it's not the same.

See GUICtrlGetHandle() in HelpFile
