_WInGetPosIn function

[martin]

If you need to resize or move child windows the WinGetPos function is awkward because the position returned is in screen coordinates, whereas WinMove uses coordinates relative to the parent client 0,0 position.

Authenticity pointed that out that ControlGetPos does the job but not for the position of a child in a child whereas this does.

; #FUNCTION# ================================================================================
  ; Name...........: _WinGetPosIn
  ; Description ...: Returns an array of coordinates for $childw with the position coordinates
  ;               relative to the 0,0 client area of $parentW
  ; Parameters  .... $childw the window handle or title whose position is required
  ;               $childText the text in the child window (can be "")
  ;               $parentw
  ;               $parentText
  ; On success 
  ;   returns an array with 4 elements
  ;    [x,y,childwidth,childheight]
  ;     where x,y is the position relative to the parent client area 0,0
  ; On failure 
  ;   returns 0 and sets @error to 1 
  ;   and sets @Extended to 1 if the $ChildW is not a window
  ;                         2 if $parentW is not a window
  ;                         3 if either window is minimized
  ;                         4 if failed to get coordinates for $parentw
  ; NOTE- It is not required that $childW is actually a child of $parentW
  ;     although this is when the function is most useful

            If BitAND(WinGetState($childW), 16) Or BitAND(WinGetState($parentW), 16) Then Return seterror(1,3,0)

Use ControlGetPos unless you need the position of a window in a child window.

EDIT: Changed to make it the same format as ControlGetPos

And what about ControlGetPos?

Well I never thought to use ControlGetPos for a child window, but now you say that It would be obvious. I'll try it.

Yes, of course it works. Thanks authenticity. I'll leave the post as a monument to my stupidity.

But then again I found that in the script I was using it ControlGetPosition desn't work for a window in a child window so I'm not quite so stupid maybe.
