Toolbar button commands

4 posts in this topic

I have a working program currently driven largely through menu selections. I would like to add a toolbar where most of the tollbar button actions are basically the same as menu items, but quicker to access. I have been wading around in toolbar examples, MSDN pages etc, it's clearly going to be a bit of a slog to get everything right, including tooltips etc. I thought I would start with something simple to prove the principle.

Using bits from the help file examples I have a small program that successfully displays a toolbar. However, what seemed like the most elegant way to deal with the button commands does not seem to work. My understanding was that a toolbar button fires a WM_COMMAND message, with the command Id set by the second parameter in the call to

_GUICtrlToolbar_AddButton ( $hWnd, $iID, $iImage)

so I though it would be a good idea to set this Id to the same value as my menu item Id; then it would run the same task which is what I wanted. This did not work. I am using message loop mode and would like to stick with this because some of my scripts run hardware at the same time as the gui; it is easier if I don't have to worry about code being interrupted with the hardware in an unknown state . So I added a handler for WM_COMMAND, with some cribbed display code to try and see why. The toolbar button defintely fired a WM_COMMAND message and the Id looked the same, so no explanation there.

I guess the issue is with GUIGetMsg() which may be constructed to ignore all but a limited number of control handles, i.e. those made with the GuiCtrlCreate... commands; this is speculation.

I would dearly love to find a tidy way to get around this. Having some controls handled in the message loop and some in a WM_COMMAND handler, performing the same task, feels ugly. I would be very grateful for further insight from someone experienced with handling a toolbar. Perhaps I should be trying to fire the menu item. I have attached a code snippet to try and illustrate the issue.

SteveJM,

You are correct - the Control IDs are not at all the same. GUIGetMsg uses the AutoIt -defined CIDs (actually indices within an internal array of controls) while the toolbar uses an entirely separate set of values.

Anyway, I would use a dummy control to action the toolbar buttons - something like this:

AutoItSetOption("MustDeclareVars", 1)


#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiToolbar.au3>
#include <GuiReBar.au3>

Global $uiDlg = GUICreate("Toolbar trial", 245, 137, 207, 121)
Global $MenuItem2 = GUICtrlCreateMenu("&File")
Global $miBeep = GUICtrlCreateMenuItem("Beep", $MenuItem2)
Global $btnBeep = GUICtrlCreateButton("Beep higher", 72, 64, 105, 25)
GUISetState(@SW_SHOW)

; Start with a default toolbar
Global $hToolbar = _GUICtrlToolbar_Create($uiDlg)

; I need an image list. I can make it out
; of a wide bit map, or I can populate it with standard images from comctl32.dll
; Let's start with some standard button images, say Open & Close

Global $nButtons = 1 ; I am confused by this as we appear to be adding a whole set of button images
Global $hInst = -1 ; This means use a system set

Global $iLoc = _GUICtrlToolbar_AddBitmap($hToolbar, $nButtons, $hInst, $IDB_STD_SMALL_COLOR)

; Auto increment the ControlIDs
Global Enum $TBBeep_1 = 1001, $TBBeep_2
_GUICtrlToolbar_AddButton($hToolbar, $TBBeep_1, $STD_FILEOPEN)
_GUICtrlToolbar_AddButton($hToolbar, $TBBeep_2, $STD_DELETE)

; Create a dummy control to action via the handler
Global $cDummy = GUICtrlCreateDummy()

GUIRegisterMsg($WM_COMMAND, MY_WM_COMMAND)

Global $nMsg

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg

        Case $miBeep
            _Beep_1()

        Case $btnBeep
            _Beep_2()

            ; if the dummy is fired
        Case $cDummy
            ; Read teh ControlID sent by the handler and action the relevant function
            Switch GUICtrlRead($cDummy)
                Case $TBBeep_1
                    _Beep_1()
                Case $TBBeep_2
                    _Beep_2()
            EndSwitch

        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd

Func _Beep_1()
    Beep(300, 200)
EndFunc   ;==>_Beep_1

Func _Beep_2()
    Beep(400, 200)
EndFunc   ;==>_Beep_2

;--------------------------------------------------------------
Func MY_WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    Local $nNotifyCode = BitShift($wParam, 16)
    Local $nID = BitAND($wParam, 0x0000FFFF)
    Local $hCtrl = $lParam

    #cs
        MsgBox($MB_SYSTEMMODAL, "MY_WM_COMMAND", "GUIHWnd" & @TAB & ":" & $hWnd & @CRLF & _
        "MsgID" & @TAB & ":" & $iMsg & @CRLF & _
        "wParam" & @TAB & ":" & $wParam & @CRLF & _
        "lParam" & @TAB & ":" & $lParam & @CRLF & @CRLF & _
        "WM_COMMAND - Infos:" & @CRLF & _
        "-----------------------------" & @CRLF & _
        "Code" & @TAB & ":" & $nNotifyCode & @CRLF & _
        "CtrlID" & @TAB & ":" & $nID & @CRLF & _
        "CtrlHWnd" & @TAB & ":" & $hCtrl)
    #ce

    ; Action the dummy control and pass the ControlID of the taskbar item
    GUICtrlSendToDummy($cDummy, $nID)

    Return $GUI_RUNDEFMSG

EndFunc   ;==>MY_WM_COMMAND

Please ask if you have any questions.

Sorry to be slow to respond - time zones and work crisies. Thank you for your suggestion. It looks a nice tidy way to deal with the issue, I like it better than the Global array based solution I was working on and I will definately use your concept in preference. I appreciate you taking the time.

Now to tackle mixing my own icons with the standard ones, tooltips and then rebars to put the whole thing in. I may be back!

      I now present to you, the MS Style Splash Screen. For Rookies, Novices and anyone who wants a ready made splash screen for your gui application.

      You can now download it and also try it out yourself.
      You have three colors to choose from:
      Blue
      Red
      Green
      All three colours are from the famous programs.
      I also included the KODA form to you can have freedom with this splash screen.
      Note: the KODA form does not have the three colours as well as the correct blue. 

      Have fun and enjoy.
      Note:
      I will update the splash to add the automated 3 dots animation at a later stage.

      Hello all,
      I've been trying to figure out how to launch Google Chrome in the background (hidden) but it doesn't seem possible. I've tried the following methods:
      ShellExecute("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", "", "", "", @SW_HIDE) Also I've tried:
      ShellExecute(@ComSpec, "/c start chrome.exe","","",@SW_HIDE) Lastly I tried:
      RunWait('"'&@ProgramFilesDir&'\Google\Chrome\Application\chrome.exe" --silent-launch',@ScriptDir)  
      But all of them launch my chrome browser without hiding it. Does anyone know a workaround for this or if AutoIT just can't Chrome? 
      Bonus points if you know how to make it launch chrome hidden and make it go to https://www.autoitscript.com
       
      Thank you,

      Hi, i searched some topics but cannot found a simple way to do that:
      #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> $Form1 = GUICreate("Form1", 615, 438, 192, 124) GUISetState(@SW_SHOW) ; I tried this but user reported that it work in 2006, not seems work actually $filemenu = GUICtrlCreateMenu ("&File") $fileitem = GUICtrlCreateMenuitem ("Open",$filemenu) GuiCtrlSetImage($fileitem, "shell32.dll", 4) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Also tried:
      #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> $Form1 = GUICreate("Form1", 615, 438, 192, 124) GUISetState(@SW_SHOW) $filemenu = TrayCreateMenu("&File") $fileitem = TrayCreateItem("Open",$filemenu) ;GuiCtrlSetImage($fileitem, "shell32.dll", 4) ;GuiCtrlSetImage(TrayItemGetHandle($fileitem), "shell32.dll", 4) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Well.. thanks in advance!
       
      Ok. I found this working example from Yashied. If i cannot find a simple then i will go with it

      Hello all,
      I've been working on 4 standalone scripts. They each have their own GUI and are now independent .exe's. But instead of having 4 separate icons on my computer, is it possible to put them all together into one .exe?
      What I want is one interface with tabs. Each script's GUI would be on their own respective tab. Is this possible?
      The different scripts don't need to communicate with one another. I just want them all in one .exe.
      I can't find this anywhere... Any help would be greatly appreciated. Thank you!
