An event for treeview checkbox check ?

Recommended Posts

Hello,

I am struggling in merging GUITreeViewEx, Shelltristate and enhancing to handle a third state that means : some items under are selected.

I have difficulties handling expand order and key Space (especially when node is collapsed).

Here the zip with UDF and and example.

 

The problem I might need some advice to handle : 

1- When load Treeview, have a correct settings of the checkbox for a tristate tree
2 - Handle keyboard used for walking in tree
     Chicken is checked and  Steak is unchecked
    When walking with arrow to Meat, it gets unchecked
3 - When node is collapsed and checked thru keyboard (space)
   the middle state is possible which should not

Here is joined an animated gif showing the 3 problems

 

Thanks for your advices

You have to catch TVN_ITEMCHANGED notification in WM_NOTIFY event and test NewState/OldState change

See here for API reference

https://msdn.microsoft.com/en-us/library/windows/desktop/bb773526(v=vs.85).aspx

https://msdn.microsoft.com/en-us/library/windows/desktop/bb773425(v=vs.85).aspx

 

It's similar to ListView with checkboxes where is LVN_ITEMCHANGED notification event where AutoIt's code looks like this:

GUIRegisterMsg($WM_NOTIFY, "WM_Notify_Events")

Func WM_Notify_Events($hWndGUI, $MsgID, $wParam, $lParam)
    #forceref $hWndGUI, $MsgID, $wParam
    Local $tagNMHDR, $event

    $tagNMHDR = DllStructCreate("int;int;int", $lParam)
    $event = DllStructGetData($tagNMHDR, 3)

    If $hWndGUI = $Form1 And $wParam = $ListView1 And $disable_refresh_status = False Then
        If $event = $LVN_ITEMCHANGED Then
            $NMLISTVIEW = DllStructCreate($tagNMLISTVIEW, $lParam)
            If BitAND(DllStructGetData($NMLISTVIEW, "Changed"), $LVIF_STATE) = $LVIF_STATE And _
                DllStructGetData($NMLISTVIEW, "NewState") <> DllStructGetData($NMLISTVIEW, "OldState") Then MyFunction()
        EndIf
    EndIf

    Return $GUI_RUNDEFMSG
EndFunc

 

EDIT:

Search this forum for  TVN_ITEMCHANGED / LVN_ITEMCHANGED for more examples ...

Hello,

I am back with my adaptation to build an UDF for Tristate Treevew that automaticly update itself based on child selection.

You can play with GUITreeViewEx_Example_Loop.au3 to get a glimpse.

 

But I encountered a difference between x86 and x64. To noticed the difference (step to reporduce)
 - select item Meat (with mouse)
 - use space to select multiple time the value. on x86 the propagation occurs correctly; on  x64 you see the three possible state of the check box.

 

I think, I narrow it down to the structure $tagNMTVKEYDOWN. thru x64 it is not correctly populated (vkey is not set).

 

Tell me if I wrong. Any possible fix ?

 

Regards

      Hey Guys,
      I want to add a new checkbox with its own variable every time the add button is clicked.
      The added checkboxes should remain when I close the window or exit the script and when I reopen I should be able to add new checkboxes aswell.
      here is what I have so far..
      #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <StaticConstants.au3> #include <EditConstants.au3> #include <MsgBoxConstants.au3> #include <GuiButton.au3> $test = GUICreate("adding test", 475, 345, 500, 175) $Check1 = GUICtrlCreateCheckbox("Checkbox 1", 15, 25, 300, 25) $Button = GUICtrlCreateButton("Add", 365, 25, 90, 20) $Check2 = GUICtrlCreateCheckbox("Checkbox 2", 15, 50, 300, 25) $Check3 = GUICtrlCreateCheckbox("Checkbox 3", 15, 75, 300, 25) GUICtrlSetState($Check2, $GUI_HIDE) GUICtrlSetState($Check3, $GUI_HIDE) GUISetState(@SW_SHOW) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ; Exit Case $Button GUICtrlSetPos($Check2, 15, 50, 300, 25) GUICtrlSetState($Check2, $GUI_SHOW) Case $Button GUICtrlSetPos($Check3, 15, 75, 300, 25) GUICtrlSetState($Check3, $GUI_SHOW) EndSwitch WEnd

      I'm trying to check the status of the checkbox for sharing a folder that you see when you right-click on a  folder, go to the sharing tab, then click on Advanced Sharing.

      The check box is labelled Share this folder, and looking at it using AutoIt window info, I get the following information..
      >>>> Control <<<<
      Class:    Button
      Instance:    1
      ClassnameNN:    Button1
      Name:    
      Advanced (Class):    [CLASS:Button; INSTANCE:1]
      ID:    1020
      Text:    &Share this folder
      Position:    15, 16
      Size:    306, 13
      ControlClick Coords:    57, 4
      Style:    0x50010003
      ExStyle:    0x00000004
      Handle:    0x0000000000420A52
      I'm using the following code..
      If ControlCommand("Sharing","","[CLASS:Button; INSTANCE:1]","IsChecked","") = 0 Then
          MsgBox(0, "", "not checked")
      Else
          MsgBox(0, "", "checked")
      EndIf
      But this insists the check box isn't checked when it is.  I have also tried ControlCommand("Sharing","","[ID:1020]","IsChecked","") and ControlCommand("Sharing","","Share this folder","IsChecked","") and ControlCommand("Sharing","","&Share this folder","IsChecked",""), with no joy.
       
      Any ideas?

      Hello,
        I am having great difficulty with something I would have thought to be fairly easy.  I have an array containing (military) organization strings, similar to this:
      42nd Battalion
       Company A
        1st Platoon
         1st Squad
         2nd Squad
         3rd Squad
        2nd Platoon
         ...1st, 2nd, 3rd Squad
        3rd Platoon
        ...1st, 2nd, 3rd Squad
       Company B
        ...etc...
      I also have an associated array that contains the 'hierarchy' information associated with each string..."0", "1","2", etc   ...therefore using example above the "0" would associate with "42nd Battalion", while "1" would be "Company A", "2" is "1st Platoon", etc.  Each sequential number is a 'child' of the preceding number.  Therefore the information above would appear in the array as "0", "1", "2", "3", "3", "3", "2", "3", "3", "3", "2", "3", "3", "3", "1", etc...
        My issue is that I'm having great difficulty creating a 'Treeview' control using this information.  Mainly due to the fact that entries can, and will...repeat (for example multiple entries for "Company A", "Company B", "1st Platoon", "1st Squad", etc, etc).  The following code is operative, however it does not create the treeview items as 'child' entries of one another...it simply lists each item as a separate entity.
      For $_populate = 0 to Ubound($_HIERARCHY) - 1 _GUICtrlTreeView_BeginUpdate($idTreeView) _GUICtrlTreeView_Add($idTreeView, $_HIERARCHY[$_populate], String($_STRUCTURES[$_populate])) _GUICtrlTreeView_EndUpdate($idTreeView) Next ;Next $_populate, cycle thru '$_HIERARCHY' array to build 'TREEVIEW' Controls As I mentioned earlier I thought I could manage this...however i'm pulling out quite a bit of my hair trying to get this working properly...any help would be appreciated.  I thank you in advance.
