How to keep control ID when we have only the handle

6 posts in this topic

Hi, I haven't found any solution on french forums and hope you have one.

I have a GUICtrlTreeViewItem created by the _GUICtrlTreeView_InsertItem() function. It works, but this udf function returns the handle, and I found no way to keep the control ID that I need to check the item.

Is there a way to keep it, or a way to check the item using handle ?

Thanks

JujuLand,

If you use the UDF function to create the TreeViewItem, then you need to use the other UDF functions to interact with it. Just use the handle you get as a return on creation to identify the item.

The ControlID returned by the native AutoIt function (GUICtrlCreateTreeViewItem) is actually the index of the control in the internal Autoit control array - if you use the UDF to create the Item, there will be no entry in the array and so a ControlID makes no sense.

Perhaps if you posted a small script to show the exact problem you are having we could offer some more help. :)

A bientot, ;)

Thanks for the answer.

Well, I need the control ID to check the item with the function GUICrtlStatus(), so if there is no function to set it with the handle, I will must use another way.

For now, I only see one other way to insert an item (and keep the ID), but a bit complicated.

Add an item with GUICtrlCreateTreeViewItem (at the end of the TreeView)

And then in a for next boucle, beginning with the last item-1, copy the content to the next item , and set correctly the status, till the item where I want to insert the new item.

Have you a better way ?

Here is a short part of code how I'm doing for now (and missing) :

$rgItem=SearchExtRange($extNew,0)
   if $rgItem=-1 Then
        $sp1 = StringLeft($string,10-StringLen($extNew)) & "|"
        $sp2 = StringLeft($string,35-StringLen("Win2Tux.file")) & "|"
        $sp3 = StringLeft($string,23)
        $item= StringLower($extNew) & $sp1 & "Win2Tux.file"  & $sp2 & $sp3
        $rgItem=SearchPosInExt($extNew) ; return the range where the new item must be inserted (after this range)
        msgbox(0,"pos",$rgItem)
        $handle=_GUICtrlTreeView_InsertItem($extensionView,$item,0,$extArray[$rgItem][4]) ;
        $nbExt+=1
        ReDim $extArray[$nbExt+1][5]
     for $rg=$nbExt  To $rgItem+1
             for $col=0 to 5
               $extArray[$rg][$col] = $extArray[$rg-1][$col]
            Next
     Next
        $extArray[$rgItem][0] =$extNew
        $extArray[$rgItem][1] ="Win2Tux.file"
        $extArray[$rgItem][2] =""
        $extArray[$rgItem][3] =$handle                                      ;  <<< I need here to keep the controlID
        $extArray[$rgItem][4] =$handle
        GUICtrlSetState($extArray[$rgItem][3], $GUI_CHECKED)   ; <<< for now, it can't work
        $nbW2T+=1
        GUICtrlSetData($W2Tnumber,$nbW2T)
        Cancel0()
        _WinAPI_RedrawWindow($MyGUI, "", "", BitOR($RDW_INVALIDATE, $RDW_UPDATENOW))
   Else
        msgbox(0,$txt120,$txt121 & $extNew & $txt122)
   EndIf

Thanks

JujuLand,

I need the control ID to check the item with the function GUICrtlStatus

What function is that? Is it a UDF? If so where is the code because it is not one of the standard ones. ;)

Looking at that code (which makes little sense out of context) I see you are trying to use GUICtrlSetState($extArray[$rgItem][3], $GUI_CHECKED) to check an item. As I explained above, if the item is created with the UDF function, you cannot use the native Autoit functions to interact with it as you do not have a ControlID, only a handle. But the UDF _GUICtrlTreeView_SetChecked function is designed to check/uncheck items created by the UDF, so try using that instead. :)

You're right, it was a typo. It ought to be GUICrtlSetStatus() instead of GUICrtlStatus().

In conclusion, it's better to use generic functions for control creation, as we keep controlID and we can found handle. For deletion, UDF works without problem.

I have modified the code to use generic functions:

if $rgItem=-1 Then
        $sp1 = StringLeft($string,10-StringLen($extNew)) & "|"
        $sp2 = StringLeft($string,35-StringLen("Win2Tux.file")) & "|"
        $sp3 = StringLeft($string,23)
        $item= StringLower($extNew) & $sp1 & "Win2Tux.file"  & $sp2 & $sp3
        $rgItem=SearchPosInExt($extNew)
        $value=GUICtrlRead($ExtArray[$nbExt-1][3],1)
        $controlID=GUICtrlCreateTreeViewItem(GUICtrlRead($ExtArray[$nbExt-1][3],1),$extensionView)
        $handle=GUICtrlGetHandle($controlID)
        GUICtrlSetState($controlID,GUICtrlRead($ExtArray[$nbExt-1][3]))
        $nbExt+=1
        ReDim $extArray[$nbExt+1][5]
        $extArray[$nbExt][3]=$controlID
        $extArray[$nbExt][4]=$handle
        GUICtrlSetOnEvent($ExtArray[$nbExt][3], "extension")
        for $rg=$nbExt -1 To $rgItem+2 step -1
              for $col=0 to 3
                   $extArray[$rg][$col] = $extArray[$rg-1][$col]
             Next
             GUICtrlSetData($extArray[$rg+1][ 3],GUICtrlRead($extArray[$rg][3],1))
             GUICtrlSetState($extArray[$rg+1][ 3],GUICtrlRead($extArray[$rg][3]))
        Next
        GUICtrlSetData($extArray[$rgItem+1][ 3],GUICtrlRead($extArray[$rgItem][3],1))
        $extArray[$rgItem+1][0] =$extNew
        $extArray[$rgItem+1][1] ="Win2Tux.file"
        $extArray[$rgItem+1][2] =$controlID
        GUICtrlSetData($extArray[$rgItem+1][ 3],$item)
        GUICtrlSetState($extArray[$rgItem+1][3], $GUI_CHECKED)
        $nbW2T+=1
        GUICtrlSetData($W2Tnumber,$nbW2T)
        Cancel0()
        _WinAPI_RedrawWindow($MyGUI, "", "", BitOR($RDW_INVALIDATE, $RDW_UPDATENOW))
   Else
      msgbox(0,$txt120,$txt121 & $extNew & $txt122)
   EndIf

Thanks for the help
