Clickable Objecs in Statusbar [solved]

[BAM5]

I've looked through the forums and the help file, but I can't figure out why the button or pic objects that work out of the status bar in the gui don't work while in the status bar.

Neither events nor GUIGetMsg works.

Could someone explain what's happening here?

I could really use some help with this.

Found it after doing a google search of the forums.

Alright, the previous didn't work for controls in the status bar, but did work for when you clicked the statusbar itself.

So I could still use some help here!

Got a short-and-sweet reproducer script that demonstrates your issue?

I'll write one up right now.

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <GuiStatusBar.au3>
#include <WindowsConstants.au3>

;~ Opt("GUIOnEventMode", 1)

Dim $parts[1] = [-1]

$main = GUICreate("Statusbar clicking", 377, 80, 192, 124)
GUISetOnEvent($GUI_EVENT_CLOSE, "close")
$status = _GUICtrlStatusBar_Create($main)
_GUICtrlStatusBar_SetMinHeight($status, 27)
_GUICtrlStatusBar_SetParts($status, $parts)
$_button = GUICtrlCreateButton("This CAN'T trigger anything", 0, 0, 150, 22)
;~ GUICtrlSetOnEvent(-1, "click")
$_hndl = GUICtrlGetHandle($_button)
_GUICtrlStatusBar_EmbedControl($status, 0, $_hndl, 3)
GUISetState(@SW_SHOW)

While 1
    Sleep(10)

    Switch GUIGetMsg()
        Case $_button
            MsgBox(0, "Awesome", "This works"); doesn't actually work :(

        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func close()
    Exit
EndFunc

Func click()
    MsgBox(0, "Awesome", "This works"); doesn't actually work :(
EndFunc

I included both methods, GUIGetMsg and Events.

I see now. The problem is that messages from the button are going to the status bar process, which is separate from the GUI's. You have to subclass the status bar, which tells it to send messages to a function in your script. Here's a working example by rover:

expandcollapse popup

;the usual paint and resize issues apply with the StatusBar not being native AutoIt code
;Note: if using a resizable gui you need to recalculate StatusBar parts
#include <GUIConstantsEX.au3>
#include <Constants.au3>
#include <WindowsConstants.au3>

#include <GuiStatusBar.au3>
#include <GuiButton.au3>

Local $aparts[3] = [80, 160, -1]
$hgui = GUICreate("StatusBar Embed Control", 400, 300, -1, -1, BitOr($GUI_SS_DEFAULT_GUI, $WS_SIZEBOX,$WS_MAXIMIZEBOX))
$button = GUICtrlCreateButton('Ok', 0, 0, 100, 20)

$hstatus = _GUICtrlStatusBar_Create($hgui)
_GUICtrlStatusBar_SetParts($hstatus, $aparts)
_GUICtrlStatusBar_SetText($hstatus, "Part 1")
_GUICtrlStatusBar_SetText($hstatus, "Part 2", 1)

;$hBtnStatusBar = _GUICtrlButton_Create($hgui, "Ok", 0, 0, 0, 0)
$cBtnStatusBar = GUICtrlCreateButton('Ok', 0, 0)
$hBtnStatusBar = GUICtrlGetHandle($cBtnStatusBar)
$cBtnDummy = GUICtrlCreateDummy()
_GUICtrlStatusBar_EmbedControl($hstatus, 2, $hBtnStatusBar)

; subclass StatusBar window:
$wProcNew = DllCallbackRegister("_StatusBarWindowProc", "int", "hwnd;uint;wparam;lparam")
$wProcOld = _WinAPI_SetWindowLong($hstatus, $GWL_WNDPROC, DllCallbackGetPtr($wProcNew))
GUIRegisterMsg($WM_SIZE, "_WM_SIZE")
GUISetState()

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case -3
            ;Delete StatusBar window callback function
            _WinAPI_SetWindowLong($hstatus, $GWL_WNDPROC, $wProcOld)
            DllCallbackFree($wProcNew)
            Exit 0
        Case $button
            MsgBox(262144, '', 'Main form button is pressed!')
        Case $cBtnDummy
            MsgBox(262144, '', 'StatusBar button is pressed!')
    EndSwitch
WEnd

Func _WM_SIZE()
    _GUICtrlStatusBar_Resize($hstatus)
    Return $GUI_RUNDEFMSG
EndFunc

Func _StatusBarWindowProc($hWnd, $Msg, $wParam, $lParam)
    #forceref $hWnd, $Msg, $wParam, $lParam
    Local $nNotifyCode = BitShift($wParam, 16)
    Local $nID = BitAND($wParam, 0x0000FFFF)

    Switch $Msg
        Case $WM_COMMAND
            Switch $lParam
                Case $hBtnStatusBar
                    ;ConsoleWrite('-$nID = ' & $nID & @crlf) 
                    ;ConsoleWrite('-$nNotifyCode = ' & $nNotifyCode & @crlf) 
                    Switch $nNotifyCode
                        Case $BN_CLICKED
                            GUICtrlSendToDummy($cBtnDummy)
                            ;ConsoleWrite("$BN_CLICKED" & @CRLF)
                    EndSwitch
            EndSwitch
        Case $WM_NCPAINT ;update button position when StatusBar repainted (when gui resized or restored from minimized)
            ;must be better way of doing this
            _GUICtrlStatusBar_EmbedControl($hstatus, 2, $hBtnStatusBar)
    EndSwitch
    ; pass the unhandled messages to default WindowProc
    Return _WinAPI_CallWindowProc($wProcOld, $hWnd, $Msg, $wParam, $lParam)
EndFunc   ;==>_NewWindowProc

I thought it was something like that, but I'm not that experienced in windows programming, just autoit.
