MDI Child Window Position

2 posts in this topic

How would I go about keeping a child window in the same position it was closed inside the parent window. 

 

I use WinMove to move it back to the previous location recorded into ini but each time it saves the previous coodinates it multiplys the result and the child window is restored off-screen.

Func _RecordIni($ChildWin)
    If WinExists("UNPRODUCTIVE TECHNICIANS") Then
        Local $TechStatWinPos = WinGetPos(ControlGetHandle($WMTCLiveFeed, "", $ChildWin))
        IniWrite(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSposX", INT($TechStatWinPos[0]))
        IniWrite(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSposY", INT($TechStatWinPos[1]))
        IniWrite(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSsizeW", INT($TechStatWinPos[2]))
        IniWrite(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSsizeH", INT($TechStatWinPos[3]))
    EndIf
EndFunc

#REGION====NEWBORNS=====================================
Func CreateChildTechStats($wintitle)
    Local $Winx = IniRead(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSposX", "DEFAULT VALUE")
    Local $Winy = IniRead(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSposy", "DEFAULT VALUE")
    Local $WinW = IniRead(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSsizeW", "DEFAULT VALUE")
    Local $WinH = IniRead(@ScriptDir & "\LFConfig.ini", "TechStatsWinPos", "TECHSTATSsizeH", "DEFAULT VALUE")

    If Not WinExists($wintitle) Then
        Global $hNew_ChildTech = GUICreate($wintitle, 405, 210, 10, 100, BitOR($GUI_SS_DEFAULT_GUI,$WS_MAXIMIZEBOX,$WS_SIZEBOX,$WS_TABSTOP))
        Global $TechStatusFeed = GuiCtrlCreateListView("TECH #|STATUS|First Name|Last Name ", 5, 5, 393, 200)
        _GUICtrlListView_SetColumnWidth($TechStatusFeed, 0, 55)
        _GUICtrlListView_SetColumnWidth($TechStatusFeed, 1, 117)
        _GUICtrlListView_SetColumnWidth($TechStatusFeed, 2, 100)
        _GUICtrlListView_SetColumnWidth($TechStatusFeed, 3, 150)
        _WinAPI_SetParent($hNew_ChildTech, $WMTCLiveFeed)
        Add($ahChild, $hNew_ChildTech)
        GUISetOnEvent($GUI_EVENT_CLOSE, "CloseTechStats", $hNew_ChildTech)
        GUISetState()
        Sleep(1000)
        If WinExists($hNew_ChildTech) Then WinMove($hNew_ChildTech, "", $WinX, $WinY, $WinW, $WinH)
    Else
        CloseTechStats()
        _GUICtrlToolbar_CheckButton($Maintoolbar, $e_idTStats, True)
    EndIf
EndFunc   ;==>CreateChild
Func CloseTechStats()
    _RecordIni($hNew_ChildTech)
    GUIDelete($hNew_ChildTech)
    _GUICtrlToolbar_CheckButton($Maintoolbar, $e_idTStats, False)
EndFunc

CodeTinkerer,

You need to convert the child GUI coordinates from absolute screen values to those inside the parent GUI client area. I massaged another script to show you how you might do it:

#include <GUIConstantsEx.au3>
#include <WinApi.au3>

Local $hChild

Local $iX = 10, $iY = 10 ; Simulate ini

Local $tPoint = DllStructCreate("int X;int Y")

$hGUI = GUICreate("Parent Window", 633, 447, 192, 200)
GUICtrlCreateLabel("", 0, 0, 0, 0)
$mMain = GUICtrlCreateMenu("Child")
$mChild = GUICtrlCreateMenuItem("Create", $mMain)
GUISetState(@SW_SHOW)

While 1
    $aMsg = GUIGetMsg(1)
    Switch $aMsg[1]
        Case $hGUI ; Main GUI
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    Exit
                Case $mChild

                    ; Create child - read coords from ini if required
                    Local $hChild = GUICreate("Child", 300, 300, $iX, $iY)
                    ; Set parent
                    _WinAPI_SetParent($hChild, $hGUI)
                    GUISetState()
                    ; Disable menu
                    GUICtrlSetState($mChild, $GUI_DISABLE)
            EndSwitch

        Case Else
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    ; Gte Window position on screen
                    $aPos = WinGetPos($hChild)
                    ; Convert to position inside main GUI client area
                    DllStructSetData($tPoint, "X", $aPos[0])
                    DllStructSetData($tPoint, "Y", $aPos[1])
                    _WinAPI_ScreenToClient($hGUI, $tPoint)
                    $iX = DllStructGetData($tPoint, "X")
                    $iY = DllStructGetData($tPoint, "Y")
                    ; Now save to ini if required.....
                    ; Delete child
                    GUIDelete($hChild)
                    ; Re-enable menu
                    GUICtrlSetState($mChild, $GUI_ENABLE)
            EndSwitch

    EndSwitch

WEnd

You need to store the cords if you want to preserve them once the script has ended - if you are just re-creating the child in the same instance (as in the example), why not just take the easy route and simply hide/show it?

#include <GUIConstantsEx.au3>
#include <WinApi.au3>

Local $hChild



$hGUI = GUICreate("Parent Window", 633, 447, 192, 200)
GUICtrlCreateLabel("", 0, 0, 0, 0)
$mMain = GUICtrlCreateMenu("Child")
$mChild = GUICtrlCreateMenuItem("Create", $mMain)
GUISetState(@SW_SHOW)

While 1
    $aMsg = GUIGetMsg(1)
    Switch $aMsg[1]
        Case $hGUI ; Main GUI
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    Exit
                Case $mChild

                    If $hChild Then
                        ; Show hidden child
                        GUISetState(@SW_SHOW, $hChild)
                    Else
                        ; Create child
                        Local $hChild = GUICreate("Child", 300, 300, 10, 10)
                        ; Set parent
                        _WinAPI_SetParent($hChild, $hGUI)
                        GUISetState()
                    EndIf

                    ; Disable menu
                    GUICtrlSetState($mChild, $GUI_DISABLE)
            EndSwitch

        Case Else
            Switch $aMsg[0]
                Case $GUI_EVENT_CLOSE
                    ; Hide child
                    GUISetState(@SW_HIDE, $hChild)
                    ; Re-enable menu
                    GUICtrlSetState($mChild, $GUI_ENABLE)
            EndSwitch

    EndSwitch
WEnd
