When I have CheckBox in StatusBar using SetParent API then there is problem because you can't catch its event by standard GUIGetMsg().

I need help how to catch Check/UnCheck event in this case. 

#AutoIt3Wrapper_UseX64=n
#NoTrayIcon

#include <GUIConstants.au3>
#include <GuiStatusBar.au3>

$Form1 = GUICreate("StatusBar Checkbox", 400, 300, -1, -1, BitOR($GUI_SS_DEFAULT_GUI,$WS_MAXIMIZEBOX,$WS_SIZEBOX))
$cbx1 = GUICtrlCreateCheckbox("Sum 1", 10, 100, 120, 20)
GUICtrlSetResizing($cbx1, $GUI_DOCKLEFT+$GUI_DOCKTOP+$GUI_DOCKWIDTH+$GUI_DOCKHEIGHT)
$cbx2 = GUICtrlCreateCheckbox("Sum 2", 3, 3, 58, 15)
GUICtrlSetResizing($cbx2, $GUI_DOCKALL)
$StatusBar1 = _GUICtrlStatusBar_Create($Form1)
Dim $sb1_PartsWidth[3] = [62, 200, -1]
_GUICtrlStatusBar_SetParts($StatusBar1, $sb1_PartsWidth)
_GuiCtrlStatusBar_Resize($StatusBar1)
_SetParent($cbx2, $StatusBar1) ; after this Checkbox doesn't fire event in GUIGetMsg()
GUISetState(@SW_SHOW)
GUIRegisterMsg($WM_SIZE, "WM_SIZE")

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cbx1
            MsgBox(64, 'cbx1', 'Checked: ' & IsChecked($cbx1)) ; OK
        Case $cbx2
            MsgBox(64, 'cbx2', 'Checked: ' & IsChecked($cbx2)) ; never fired
    EndSwitch
WEnd

Func WM_SIZE($hWnd, $Msg, $wParam, $lParam)
    _GuiCtrlStatusBar_Resize($StatusBar1)
    Return $GUI_RUNDEFMSG
EndFunc

Func _SetParent($ctrl_child, $ctrl_parent)
;~  $ctrl_parent = GUICtrlGetHandle($ctrl_parent)
    $ctrl_child = GUICtrlGetHandle($ctrl_child)
    DllCall("user32.dll", "hwnd", "SetParent", "hwnd", $ctrl_child, "hwnd", $ctrl_parent)
EndFunc

Func IsChecked($control)
    Return BitAnd(GUICtrlRead($control),$GUI_CHECKED) = $GUI_CHECKED
EndFunc

 

EDIT: Maybe some WM_COMMAND / WM_NOTIFY or SubClassing?

Probably not the answer your looking for but, you could use ControlCommand and Adlibregister 

Global $g_bCbx2 = False
;~ ...
AdlibRegister("_IsChecked")
;~ ...
Func _IsChecked()
    Local $bCbx2 = ControlCommand($Form1, "", $cbx2, "IsChecked") ? True : False
    If $g_bCbx2 <> $bCbx2 Then
        MsgBox(64, 'cbx2', 'Checked: ' & $bCbx2)
        $g_bCbx2 = $bCbx2
    EndIf
EndFunc

I'm very close to solution.

Basically this works, but it's not complete yet (see commented lines): 

#AutoIt3Wrapper_UseX64=n
#NoTrayIcon

#include <GUIConstants.au3>
#include <GuiStatusBar.au3>

Global $hTab, $hDll, $pDll, $hProc

$Form1 = GUICreate("StatusBar Checkbox", 400, 300, -1, -1, BitOR($GUI_SS_DEFAULT_GUI,$WS_MAXIMIZEBOX,$WS_SIZEBOX))
$cbx1 = GUICtrlCreateCheckbox("Sum 1", 10, 100, 120, 20)
GUICtrlSetResizing($cbx1, $GUI_DOCKLEFT+$GUI_DOCKTOP+$GUI_DOCKWIDTH+$GUI_DOCKHEIGHT)
$cbx2 = GUICtrlCreateCheckbox("Sum 2", 3, 3, 58, 15)
$hcbx2 = GUICtrlGetHandle($cbx2)
GUICtrlSetResizing($cbx2, $GUI_DOCKALL)
$StatusBar1 = _GUICtrlStatusBar_Create($Form1)
Dim $sb1_PartsWidth[3] = [62, 200, -1]
_GUICtrlStatusBar_SetParts($StatusBar1, $sb1_PartsWidth)
_GuiCtrlStatusBar_Resize($StatusBar1)
_SetParent($cbx2, $StatusBar1) ; after this Checkbox doesn't fire event in GUIGetMsg()
GUISetState(@SW_SHOW)
GUIRegisterMsg($WM_SIZE, "WM_SIZE")

; Register StatusBar window proc
$hDll = DllCallbackRegister('_SBWinProc', 'ptr', 'hwnd;uint;wparam;lparam')
$pDll = DllCallbackGetPtr($hDll)
$hProc = _WinAPI_SetWindowLong($StatusBar1, $GWL_WNDPROC, $pDll)

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cbx1
            MsgBox(64, 'cbx1', 'Checked: ' & IsChecked($cbx1)) ; OK
        Case $cbx2
            MsgBox(64, 'cbx2', 'Checked: ' & IsChecked($cbx2)) ; never fired
    EndSwitch
WEnd

_WinAPI_SetWindowLong($StatusBar1, $GWL_WNDPROC, $hProc)
DllCallbackFree($hDll)

Func WM_SIZE($hWnd, $Msg, $wParam, $lParam)
    _GuiCtrlStatusBar_Resize($StatusBar1)
    Return $GUI_RUNDEFMSG
EndFunc

Func _SetParent($ctrl_child, $ctrl_parent)
;~  $ctrl_parent = GUICtrlGetHandle($ctrl_parent)
    $ctrl_child = GUICtrlGetHandle($ctrl_child)
    DllCall("user32.dll", "hwnd", "SetParent", "hwnd", $ctrl_child, "hwnd", $ctrl_parent)
EndFunc

Func IsChecked($control)
    Return BitAnd(GUICtrlRead($control),$GUI_CHECKED) = $GUI_CHECKED
EndFunc

Func _SBWinProc($hWnd, $iMsg, $wParam, $lParam)
;~     Local $i_code = BitAND($wparam, 0xFFFF)
;~     Local $i_notify = BitShift($wparam, 16)

    If $hWnd = $StatusBar1 Then
        Switch $iMsg
            Case $WM_COMMAND
                If $wParam = $cbx2 Then MsgBox(64, 'cbx2', 'Checked: ' & IsChecked($cbx2))
;~              If $i_code = $cbx2 And $i_notify = $NM_CLICK Then MsgBox(64, 'cbx2', 'Checked: ' & IsChecked($cbx2))
        EndSwitch
    EndIf
    Return _WinAPI_CallWindowProc($hProc, $hWnd, $iMsg, $wParam, $lParam)
EndFunc

 

EDIT: Explanation

By default WM_COMMAND event/message from checkbox is delivered to main GUI form (and can be catch in main GUI loop) because it is its parent.

Now when we change parent of checkbox to StatusBar then WM_COMMAND event/message from checkbox is delivered to StatusBar as its parent.

So we have to register window procedure of StatusBar and catch WM_COMMAND (from our checkbox) there.

This works but the only one remaining problem is how to distinguish notification code in this case (I want to react only to NM_CLICK), because in my example $i_notify is always zero.

This problem is only cosmetic, because my checkbox generate only one WM_COMMAND (when clicked) so it works fine even if I don't do testing of NOTIFY/NM_CLICK.

What about this solution? 

#AutoIt3Wrapper_UseX64=n

Thanks all for alternative solutions.

 

My final working solution: 

#AutoIt3Wrapper_UseX64=n
#NoTrayIcon

#include <GUIConstants.au3>
#include <GuiStatusBar.au3>

$Form1 = GUICreate("StatusBar Checkbox", 400, 300, -1, -1, BitOR($GUI_SS_DEFAULT_GUI,$WS_MAXIMIZEBOX,$WS_SIZEBOX))
$cbx1 = GUICtrlCreateCheckbox("Sum 1", 10, 100, 120, 20)
GUICtrlSetResizing($cbx1, $GUI_DOCKLEFT+$GUI_DOCKTOP+$GUI_DOCKWIDTH+$GUI_DOCKHEIGHT)
$cbx2 = GUICtrlCreateCheckbox("Sum 2", 3, 3, 58, 15)
$hcbx2 = GUICtrlGetHandle($cbx2)
GUICtrlSetResizing($cbx2, $GUI_DOCKALL)
$cbx2_dummy = GUICtrlCreateDummy()
$StatusBar1 = _GUICtrlStatusBar_Create($Form1)
Dim $sb1_PartsWidth[3] = [62, 200, -1]
_GUICtrlStatusBar_SetParts($StatusBar1, $sb1_PartsWidth)
_GuiCtrlStatusBar_Resize($StatusBar1)
_SetParent($cbx2, $StatusBar1)
GUISetState(@SW_SHOW)
GUIRegisterMsg($WM_SIZE, "WM_SIZE")

; Register StatusBar window proc
Global $hDll, $pDll, $hProc
$hDll = DllCallbackRegister('_SBWinProc', 'ptr', 'hwnd;uint;wparam;lparam')
$pDll = DllCallbackGetPtr($hDll)
$hProc = _WinAPI_SetWindowLong($StatusBar1, $GWL_WNDPROC, $pDll)

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cbx1
            MsgBox(64, 'cbx1', 'Checked: ' & IsChecked($cbx1))
        Case $cbx2_dummy
            MsgBox(64, 'cbx2', 'Checked: ' & IsChecked($cbx2))
    EndSwitch
WEnd

_WinAPI_SetWindowLong($StatusBar1, $GWL_WNDPROC, $hProc)
DllCallbackFree($hDll)

Func WM_SIZE($hWnd, $Msg, $wParam, $lParam)
    _GuiCtrlStatusBar_Resize($StatusBar1)
    Return $GUI_RUNDEFMSG
EndFunc

Func _SBWinProc($hWnd, $iMsg, $wParam, $lParam)
    If $hWnd = $StatusBar1 And $iMsg = $WM_COMMAND And $wParam = $cbx2 Then GUICtrlSendToDummy($cbx2_dummy)
    Return _WinAPI_CallWindowProc($hProc, $hWnd, $iMsg, $wParam, $lParam)
EndFunc
