Toolbar button commands

Recommended Posts

SteveJM

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!

      Good evening everyone
      First, I want to apologize with you for the title not very clear, but I thought a little bit on which title to set at the thread, and this is the one that came in mind.
      Now, let me explain what I'm trying to understand.

      I am making an application ( with n clients ), with an SQLite Database, which has a Main form, and n sub-forms... 
      Since these sub-forms are called several times, because they are used to add or update records to the Database, I put the code that generates the GUI of these sub-forms in Functions.
      There are two sub-forms which are "treated" as two main forms, since even them have n sub-forms, which perform various tasks.
      Where am I stucked?

      For the Main form I created a Status Bar, in order to display messages ( add/delete/update/search results ), and it works perfectly with all the forms which don't have other sub-forms.
      For the two forms, which indeed have n sub-forms, I created two separated Status Bars, which are (re)created everytime I call the function that then displays the form.
      Practically, I can't set icons to these two Status Bars, and I don't know why.
      I'm really sorry that I don't feel clear enough, so, here you are an example of what I am saying.
      I recreated exactly what my script does:
      #include <GuiButton.au3> #include <GUIConstantsEx.au3> #include <GuiStatusBar.au3> #include <WindowsConstants.au3> Opt("GUIOnEventMode", 1) Global $frmSubForm, _ $txtSubFormField, _ $sbSubFormStatusBar, _ $objSB_IconError = _WinAPI_LoadShell32Icon(109), _ $objSB_IconInformation = _WinAPI_LoadShell32Icon(277) #Region ### START Koda GUI section ### Form= $frmMainForm = GUICreate("Main Form", 300, 300, -1, -1) GUISetOnEvent($GUI_EVENT_CLOSE, "ExitApplication") $sbMainStatusBar = _GUICtrlStatusBar_Create($frmMainForm) $btnCreateSubForm = GUICtrlCreateButton("Create Sub Form", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "GenerateSubForm") GUICtrlSetFont(-1, 10, 400, 0, "Arial") _GUICtrlStatusBar_SetSimple($sbMainStatusBar) _GUICtrlStatusBar_SetText($sbMainStatusBar, "") GUISetState(@SW_SHOW, $frmMainForm) #EndRegion ### END Koda GUI section ### While 1 Sleep(100) WEnd Func ExitApplication() Exit EndFunc Func GenerateSubForm() #Region ### START Koda GUI section ### Form= $frmSubForm = GUICreate("Sub-Form", 300, 300, -1, -1, -1, -1, $frmMainForm) GUISetOnEvent($GUI_EVENT_CLOSE, "DeleteSubForm") $txtSubFormField = GUICtrlCreateInput("", 0, 0, 100, 20) $btnCheckSubFormField = GUICtrlCreateButton("Check Field", 105, 110, 75, 41, BitOR($BS_CENTER,$BS_VCENTER,$BS_MULTILINE)) GUICtrlSetOnEvent(-1, "CheckSubFormField") GUICtrlSetFont(-1, 10, 400, 0, "Arial") $sbSubFormStatusBar = _GUICtrlStatusBar_Create($frmSubForm) _GUICtrlStatusBar_SetSimple($sbSubFormStatusBar) _GUICtrlStatusBar_SetText($sbSubFormStatusBar, "") GUISetState(@SW_SHOW, $frmSubForm) GUISetState(@SW_DISABLE, $frmMainForm) #EndRegion ### END Koda GUI section ### EndFunc Func DeleteSubForm() ; Declared Globally => $frmSubForm GUIDelete($frmSubForm) GUISetState(@SW_ENABLE, $frmMainForm) EndFunc Func WriteToStatusBar($sbStatusBar, $objSB_Icon, $strText) _GUICtrlStatusBar_SetIcon($sbStatusBar, 0, $objSB_Icon) _GUICtrlStatusBar_SetText($sbStatusBar, $strText) ConsoleWrite("Icon Handle: " & $objSB_Icon & @CRLF) EndFunc Func CheckSubFormField() ; Declared Globally => $txtSubFormField If GUICtrlRead($txtSubFormField) = "" Then ; Declared Globally => $sbStatusBar WriteToStatusBar($sbSubFormStatusBar, $objSB_IconError, "Field NOK.") Else WriteToStatusBar($sbSubFormStatusBar, $objSB_IconInformation, "Field OK.") EndIf EndFunc The text is set, but icon is not.
      Could someone please tell me why?
      Thanks everyone in advance  

      Best Regards.

      Hi, everybody
      I look for GUI whose behavior similar to the message of an email client or antivirus
      In other words:
          Any PC screen able to calculate the size
          To consider the Task bar size
          To find the lower corner on the right/below and to nestle on it

      Notes:
      In GUI the GUICtrlCreateEdit field (as option) - that can be received and displayed through variable information
      Thanks a lot
      PS
      I use the translator, excuse if something is not clear

      Hi,
      I'd like to show a progress bar for an operation performed by an external program my script is running silently, I want to show it in a GUI I created using the GUICtrlCreateProgress but I have no idea how to do it.
      The important thing to point out is that there's no way of knowing how long the external program will run, as it is a file splitter and it depends on the size of file it splits and the split parts size.
      Can someone point me in the right direction or give me an example how to do so?
      This is my RunWait command:
      RunWait($MYFILES1 & '\fsplit.exe -split ' & $Size & ' mb ' & $File & " -f " & $File & "." & $extension) It uses multiple variables declared and set earlier in the script, how will I got about having the progress of that command shown using GUICtrlCreateProgress ? Is it possible?
      Thank you.
