How to tell if my child window is inside its parent?

[AustrianOak]

I created a child window inside a parent window and I sometimes drag the child out. Is there any way I can determine if the child is inside or not?

In need of help. I'm really stumped on this one...

I imagine you set the parent of the child when you created the child using the last parameter in GuiCreate. You can use WinGetPos to find the positions of the parent and the child and then check if the child is inside the parent. To be sure you might need to guse WinGetClientSize.

If you don't want to be able to drag the child out of the parent then create the child as a normal window and then have

DllCall("user32.dll", "int", "SetParent", "hwnd", $child, "hwnd", $parent)

Yep, you can. The point is to set an IF statement if the coords of the top left corner of the parent are both smaller than the coords of the top left corner of the child, AND IF both the coords of the botom right corner of the parent are bigger than the coords of the bottom right coords of the child. I've repeated myself so all would be very clear. I hope you understood. You can eventually set an if statement with 2 conditions OR the other 2, and set the message box to "Partial overlapping". Here it is:

#include <GUIConstantsEx.au3>
Opt("GUIOnEventMode", 1)


Local $ParentWidth = 250, $ParentHeight = 250
Local $ChildWidth = $ParentWidth - 80, $ChildHeight = $ParentHeight - 80


$ParentWin = GUICreate("Parent GUI", $ParentWidth, $ParentHeight)
GUISetOnEvent($GUI_EVENT_CLOSE, "ParentClose")
$ParentWin_Pos = WinGetPos($ParentWin, "")
GUISetState(@SW_SHOW)
$ChildWin = GUICreate("Child GUI", $ChildWidth, $ChildHeight, $ParentWin_Pos[0] + 100, $ParentWin_Pos[1] + 100, -1, -1, $ParentWin)
GUISetOnEvent($GUI_EVENT_CLOSE, "ChildClose")

GUISetState(@SW_SHOW)
GUISwitch($ParentWin)


While 1
    $ParentWin_Pos = WinGetPos($ParentWin, "")
    $ChildWin_Pos = WinGetPos($ChildWin, "")
    If $ParentWin_Pos[0] < $ChildWin_Pos[0] And $ParentWin_Pos[1] < $ChildWin_Pos[1] And $ParentWin_Pos[0] + $ParentWidth > $ChildWin_Pos[0] + $ChildWidth And $ParentWin_Pos[1] + $ParentHeight > $ChildWin_Pos[1] + $ChildHeight Then ;Here it's the whole big deal
        MsgBox(262192, "", "Inside!")
    Else
        MsgBox(262192, "", "Outside!")
    EndIf
WEnd

Func ParentClose()
    MsgBox(64, "Test", "Parent GUI will now close.")
    GUISwitch($ParentWin)
    GUIDelete()
    Exit
EndFunc   ;==>ParentClose

Func ChildClose()
    MsgBox(64, "Test", "Child GUI will now close.")
    GUISwitch($ChildWin)
    GUIDelete()
EndFunc   ;==>ChildClose

Tell me if this is what you wanted.

I had to modify your code to fit into the way I programmed some things and its giving me an error on the big If line saying "Subscript used with non array variable"

Func Test()
    $ParentWidth = 215
    $ParentHeight = 544
    $ChildWidth = 26
    $ChildHeight = 26
    
    For $i = 0 To ubound($calling)-1
        $ParentWin_Pos = WinGetPos($GUI, "")
        $ChildWin_Pos = WinGetPos($calling[$i], "")
        If $ParentWin_Pos[0] < $ChildWin_Pos[0] And $ParentWin_Pos[1] < $ChildWin_Pos[1] And $ParentWin_Pos[0] + $ParentWidth > $ChildWin_Pos[0] + $ChildWidth And $ParentWin_Pos[1] + $ParentHeight > $ChildWin_Pos[1] + $ChildHeight Then;Here it's the whole big deal
            GUIDelete($calling[$i])
        Else
        EndIf
    Next
EndFunc

Check if it's an array...

Func Test()
    $ParentWidth = 215
    $ParentHeight = 544
    $ChildWidth = 26
    $ChildHeight = 26
    
    For $i = 0 To ubound($calling)-1
        $ParentWin_Pos = WinGetPos($GUI)
        $ChildWin_Pos = WinGetPos($calling[$i])
        
        If IsArray($ParentWin_Pos) And IsArray($ChildWin_Pos) And $ParentWin_Pos[0] < $ChildWin_Pos[0] And _
            $ParentWin_Pos[1] < $ChildWin_Pos[1] And $ParentWin_Pos[0] + $ParentWidth > $ChildWin_Pos[0] + $ChildWidth And _
            $ParentWin_Pos[1] + $ParentHeight > $ChildWin_Pos[1] + $ChildHeight Then ;Here it's the whole big deal
            
            GUIDelete($calling[$i])
        Else
            
        EndIf
    Next
EndFunc

When I put in IsArray it gives me an error saying "Error parsing function call" point to IsArray....

What AutoIt version you are using?

[AustrianOak]

3.2.11.5

I'm using a different method in my coding so this problem is solved.
