window restored position without actually restoring

10 posts in this topic

How can I get a window's "restored" coordinates (X, Y , width & height) without actually restoring it from a minimized or maximized state? I have a situation where a window is maximized (or minimized) and I need to know where the OS is going to put the window in the restored state before it actually happens.

Restore it hidden, get the pos, then put it back minimized and unhidden.

OK, you can't leave me hang'n! How do you make that work? I create a DLL struct and make the DLL call, and it almost works, but I don't understand how you get a struct out of a struct.

The GetWindowPlacement call uses a WINDOWPLACEMENT struct, which I don't know how to create because I don't know how to put "POINT" and "RECT" types in it (though they are available as $tag_ variables in WinAPI.au3).

This works...

#include <WinAPI.au3>

Run("notepad.exe", @TempDir, @SW_MINIMIZE)
WinWait("Untitled - Notepad")
$hWindow = WinGetHandle("Untitled - Notepad")
_WinAPI_GetWindowPlacement($hWindow)

Func _WinAPI_GetWindowPlacement($hWND)
    Local $strPointMinPosition = DllStructCreate($tagPOINT); "int X;int Y"
    Local $ptrPointMinPosition = DllStructGetPtr($strPointMinPosition)
    
    Local $strPointMaxPosition = DllStructCreate($tagPOINT); "int X;int Y"
    Local $ptrPointMaxPosition = DllStructGetPtr($strPointMaxPosition)
    
    Local $strRECT = DllStructCreate($tagRECT); "int Left;int Top;int Right;int Bottom"
    Local $ptrRECT = DllStructGetPtr($strRECT)
    
    Local $strWindowPlacement = DllStructCreate("UINT length; UINT flags; UINT showCmd; " & _
        "PTR ptMinPosition; PTR ptMaxPosition; PTR rcNormalPosition")
    Local $ptrWindowPlacement = DllStructGetPtr($strWindowPlacement)    
    
    $avRET = DllCall("user32.dll", "int", "GetWindowPlacement", "hwnd", $hWND, "ptr", $ptrWindowPlacement)
    If $avRET[0] <> 0 Then
        $sMsg = "DLL call succeded: $avRET[0] = " & $avRET[0] & @CRLF & @CRLF
        $sMsg &= "$strWindowPlacement:" & @CRLF
        $sMsg &= @TAB & "length = " & DllStructGetData($strWindowPlacement, "length") & @CRLF
        $sMsg &= @TAB & "flags = " & DllStructGetData($strWindowPlacement, "flags") & @CRLF
        $sMsg &= @TAB & "showCmd = " & DllStructGetData($strWindowPlacement, "showCmd") & @CRLF
        MsgBox(64, "Success", $sMsg)        
    Else
        MsgBox(16, "Failed", "Dll call failed: $avRET[0] = " & $avRET[0])
    EndIf
EndFunc
...but it stops short of reading out the "POINT" and "RECT" values.

How do you do that?

:)

Edit: Fixed broken link.

$tagWINDOWPLACEMENT = "uint sizeof;uint flags;uint showCmd;int MinPos[2];int MaxPos[2];int NormPos[4]"

or

$tagWINDOWPLACEMENT = "uint sizeof;uint flags;uint showCmd;int MinPosX;int MinPosY;int MaxPosX;int MaxPosY;int NormPosX1;int NormPosY1;int NormPosX2;int NormPosY2"

Whichever you prefer.

Whichever you prefer.

The first one worked! (The second caused the Dll call to fail.) This is a start:
#include <WinAPI.au3>

Run("notepad.exe", @TempDir, @SW_MINIMIZE)
WinWait("Untitled - Notepad")
$hWindow = WinGetHandle("Untitled - Notepad")
_WinAPI_GetWindowPlacement($hWindow)
WinClose($hWindow)

Func _WinAPI_GetWindowPlacement($hWND)
    Local $strWindowPlacement = DllStructCreate("UINT length; UINT flags; UINT showCmd; " & _
        "int MinPos[2]; int MaxPos[2]; int NormPos[4]")
    
    Local $ptrWindowPlacement = DllStructGetPtr($strWindowPlacement)    
    
    $avRET = DllCall("user32.dll", "int", "GetWindowPlacement", "hwnd", $hWND, "ptr", $ptrWindowPlacement)
    If $avRET[0] <> 0 Then
        $sMsg = "DLL call succeded: $avRET[0] = " & $avRET[0] & @CRLF & @CRLF
        $sMsg &= "$strWindowPlacement:" & @CRLF
        $sMsg &= @TAB & "length = " & DllStructGetData($strWindowPlacement, "length") & @CRLF
        $sMsg &= @TAB & "flags = " & DllStructGetData($strWindowPlacement, "flags") & @CRLF
        $sMsg &= @TAB & "showCmd = " & DllStructGetData($strWindowPlacement, "showCmd") & @CRLF
        $sMsg &= "PointMinPosition:" & @CRLF
        $sMsg &= @TAB & "MinX = " & DllStructGetData($strWindowPlacement, "MinPos", 1) & @CRLF
        $sMsg &= @TAB & "MinY = " & DllStructGetData($strWindowPlacement, "MinPos", 2) & @CRLF
        $sMsg &= "PointMaxPosition:" & @CRLF
        $sMsg &= @TAB & "MaxX = " & DllStructGetData($strWindowPlacement, "MaxPos", 1) & @CRLF
        $sMsg &= @TAB & "MaxY = " & DllStructGetData($strWindowPlacement, "MaxPos", 2) & @CRLF
        $sMsg &= "RectNormPosition:" & @CRLF
        $sMsg &= @TAB & "left = " & DllStructGetData($strWindowPlacement, "NormPos", 1) & @CRLF
        $sMsg &= @TAB & "top = " & DllStructGetData($strWindowPlacement, "NormPos", 2) & @CRLF
        $sMsg &= @TAB & "right = " & DllStructGetData($strWindowPlacement, "NormPos", 3) & @CRLF
        $sMsg &= @TAB & "bottom = " & DllStructGetData($strWindowPlacement, "NormPos", 4)
        MsgBox(64, "Success", $sMsg)        
    Else
        MsgBox(16, "Failed", "Dll call failed: $avRET[0] = " & $avRET[0])
    EndIf
EndFunc

I can normalize the return data from the function instead of a MsgBox(), and we have a working call! Thanks, Siao!

:)

Eek, guess I could have saved some time and refreshed this page... I just sent you a PM on it salty .. Siao has a great grasp on api calls (as well as many other things) :)

Here is the new function, _WinAPI_GetWindowPlacement(), built based on Siao's and SmOke_N's help:

#include <WinAPI.au3>

; Get the normal position of a minimized window
Run("notepad.exe", @TempDir, @SW_MINIMIZE)
WinWait("Untitled - Notepad")
$hWindow = WinGetHandle("Untitled - Notepad")
$strRET = _WinAPI_GetWindowPlacement($hWindow)

$sMsg = "$strWindowPlacement:" & @CRLF & @CRLF
$sMsg &= @TAB & "length = " & DllStructGetData($strRET, "length") & @CRLF
$sMsg &= @TAB & "flags = " & DllStructGetData($strRET, "flags") & @CRLF
$sMsg &= @TAB & "showCmd = " & DllStructGetData($strRET, "showCmd") & @CRLF & @CRLF
$sMsg &= "ptMinPosition:" & @CRLF
$sMsg &= @TAB & "MinX = " & DllStructGetData($strRET, "ptMinPosition", 1) & @CRLF
$sMsg &= @TAB & "MinY = " & DllStructGetData($strRET, "ptMinPosition", 2) & @CRLF & @CRLF
$sMsg &= "ptMaxPosition:" & @CRLF
$sMsg &= @TAB & "MaxX = " & DllStructGetData($strRET, "ptMaxPosition", 1) & @CRLF
$sMsg &= @TAB & "MaxY = " & DllStructGetData($strRET, "ptMaxPosition", 2) & @CRLF & @CRLF
$sMsg &= "rcNormalPosition:" & @CRLF
$sMsg &= @TAB & "left = " & DllStructGetData($strRET, "rcNormalPosition", 1) & @CRLF
$sMsg &= @TAB & "top = " & DllStructGetData($strRET, "rcNormalPosition", 2) & @CRLF
$sMsg &= @TAB & "right = " & DllStructGetData($strRET, "rcNormalPosition", 3) & @CRLF
$sMsg &= @TAB & "bottom = " & DllStructGetData($strRET, "rcNormalPosition", 4)
MsgBox(64, "Success", $sMsg)

I feel like I learned something today!

:)

Edit: Fixed line-wrapped header on function for SmOke_N. Picky, picky, picky...

P.S. Posted _WinAPI_GetWindowPlacement() to the example forum. If it needs any more changes, they will be posted there. Hopefully it will soon be joined there by _WinAPI_SetWindowPlacement().

Yeah, I learned a few things myself... you might want to watch that word wrap on your function headers.
