MsgLoop - SetState of Ctrl AND perform additional actions

4 posts in this topic

#1 ·  Posted (edited)

I'm new to AutoIt so this is going to be a little tough to explain. Please ask for clarification if needed.

So in the message loop mode, you GUI is polled constantly and you have switch statements to determine which control was clicked on. 

I have multiple check boxes, and at the end, there is a "Select All" check box which selects all checkboxes (so complex, right?). 

So depending on the checkbox selected, it's supposed to update multiple values/variables, and reset them if unchecked. Also, I want to make sure that certain combination of check boxes are not selected because they are invalid and the end user would be notified if that specific combination is selected (and not allow the program to continue). 

So if:

While 1; msg loop
...
...
Case $chBox1 ;is called, 
    ;I want to perform multiple things
    ;...
    ;..

...
..

Originally, I implemented it so when the $SelectAllCheckBox is checked, it simply checks all other checkboxes by having multiple calls to: GUICtrlSetState($chBox1...) for each checkBox.

But if I simply change the state of the check box using the method above, then I can't do the additional things (without having ugly re-written code).  

How do I DIRECTLY send a msg to the GUI so that when GUIGetMsg() is called, it's the msg I set? Or is there a better way to do this? Should I have used onEvent instead?

You shouldn't be looking at the events from clicking on the checkboxes, you should use a button that only performs an action by reading the checked and unchecked checkboxes. You can monitor the CheckAll checkbox, but you shouldn't be monitoring the rest of them, it gets far too complicated when you do it that way.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Glad I asked this on the forums and stopped myself from making it too complicated and then quitting out of frustration...

Thanks BrewManNH!

AnAlien,

I would do it something like this: :)

#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

Global $aCheck[3], $aDummy[3]

$hGUI = GUICreate("Test", 500, 500)

; Create checkboxes and linked dummy controls
For $i = 0 To UBound($aCheck) - 1
    $aCheck[$i] = GUICtrlCreateCheckbox("Checkbox " & $i, 10, 10 + (40 * $i), 200, 20)
    $aDummy[$i] = GUICtrlCreateDummy()
Next

$cCheckAll = GUICtrlCreateCheckbox("Check All", 10, 130, 200, 20)

GUISetState()

While 1

    $iMsg = GUIGetMsg()
    Switch $iMsg
        Case $GUI_EVENT_CLOSE
            Exit
            
        Case $cCheckAll
            ; Decide on state to set
            $iState = ( (GUICtrlRead($cCheckAll) = 1) ? ($GUI_CHECKED) : ($GUI_UNCHECKED) )
            ; Loop through the checkboxes
            For $i = 0 To UBound($aCheck) - 1
                ; If we are changing a checkbox state
                If GUICtrlRead($aCheck[$i]) <> $iState Then
                    ; Fire the relevant dummy control
                    GUICtrlSendToDummy($aDummy[$i])
                EndIf
                ; Chenge the state
                GUICtrlSetState($aCheck[$i], $iState)
            Next
            
        Case Else
            For $i = 0 To UBound($aCheck) - 1
                ; Was a ccheckbox changed
                If $iMsg = $aCheck[$i] Then
                    ; Check if valid combination
                    If _Valid_Combination() Then
                        ; Call code to run
                        Call("_Check" & $i)
                    Else
                        MsgBox($MB_SYSTEMMODAL, "Error", "Invalid checkbox combination")
                    EndIf
                    ; No point in looking further
                    ExitLoop
                EndIf
                ; Was s dummy fired
                If $iMsg = $aDummy[$i] Then
                    ; Call code to run
                    Call("_Check" & $i)
                    ; No point in looking further
                    ExitLoop
                EndIf
            Next

    EndSwitch

WEnd

Func _Check0()

    If GUICtrlRead($aCheck[0]) = 1 Then
        MsgBox($MB_SYSTEMMODAL, "Hi", "Running code for Check 0 checked")
    Else
        MsgBox($MB_SYSTEMMODAL, "Hi", "Running code for Check 0 unchecked")
    EndIf

EndFunc

Func _Check1()

    If GUICtrlRead($aCheck[1]) = 1 Then
        MsgBox($MB_SYSTEMMODAL, "Hi", "Running code for Check 1 checked")
    Else
        MsgBox($MB_SYSTEMMODAL, "Hi", "Running code for Check 1 unchecked")
    EndIf

EndFunc

Func _Check2()

    If GUICtrlRead($aCheck[2]) = 1 Then
        MsgBox($MB_SYSTEMMODAL, "Hi", "Running code for Check 2 checked")
    Else
        MsgBox($MB_SYSTEMMODAL, "Hi", "Running code for Check 2 unchecked")
    EndIf

EndFunc

Func _Valid_Combination()

    ; Create a strign to match the current checkbox state
    $sValid = ""
    For $i = 0 To UBound($aCheck) - 1
        $sValid &= ( (GUICtrlRead($aCheck[$i]) = 1) ? ("X") : ("-") )
    Next
    ; Now check the validity of that combination
    Switch $sValid
        Case "XXX", "X-X", "X--", "-X-", "--X"
            Return True
    EndSwitch
    Return False

EndFunc
Please ask if you have any questions. :)
