TreeView check box to select only item, feed children to next loop

7 posts in this topic

Hi Everyone

I have a very sexy Treeview that creates a "phonebook" type listing

+Jones [an item]

---- Albert [a child]

+Webster

---- David

---- John

---- Peter

It uses these styles:

Local $iStyle = BitOr ( $TVS_EDITLABELS, $TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGANDDROP, $TVS_SHOWALWAYS, $TVS_CHECKBOXES )

It is created with GUICtrlCreateTreeview() and uses 

_GUICtrlTreeView_Add()

and 

 _GUICtrlTreeView_AddChild()

I want checkboxes ONLY on the items (surnames above), not the children. And, preferably the user must be able to click (select) the line (child) for info, but that info must preferable point to the item, so when browsing and click "John" the checkbox for WEBSTER should get ticked and return the handle/control id for WEBSTER, which I can then use to manipulate the item (and children) further.

Issue #1

My first issue is to get the checkboxes away from the children.

Issue #2

The info from the children can probably gleaned from here:

Thx @Melba23 :)

 Thx, skysnake

Skysnake,

I went looking how to have checkboxes only on certain items of the TreeView when I was working on my ChooseFileFolder UDF and found that you needed to create a completely owner-drawn TreeView control, which was far too much trouble in my opinion. What I did as a workaround was to look at the level of the item within the TreeView and only allow checks to be placed in those items which were allowed to accept them. You can find a function to do this in the GuiTreeView UDF - as well as another function allowing you to determine the parent for a given child, which will allow you to link back to the family name when a child is selected.

The GuiTreeView UDF has lots of interesting functions - and the ChooseFileFolder UDF shows how to use quite a few of them if you wish to take a look.

Thank your for the reply.

Hmm, I was really hoping there was somehthing like a GuiCtrlTreeViewGetItemforSelectedChild() ;)

 

Idea now is to include the item inside the child line ( a nested value), then simply use extract that value from the selected child and select the relevant value. Will try to post a working script by Monday.

 

Thanks again.

Some treeview items with checkboxes and some without: I'm pretty sure it can be done in the same way as it's done for listview items here. I'll leave the details to you guys.

LarsJ,

It is even easier than that - adjusting the commented-out line removes the checkboxes from either root or children:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiTreeView.au3>

Local $aItem[4]

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

$hTV = _GUICtrlTreeView_Create($hGUI, 10, 10, 450, 450, BitOR($WS_BORDER, $TVS_CHECKBOXES, $TVS_HASLINES, $TVS_HASBUTTONS, $TVS_LINESATROOT))

$hRoot = _GUICtrlTreeView_Add($hTV, 0, "Root")

For $i = 1 To 3
    $aItem[$i]= _GUICtrlTreeView_AddChild($hTV, $hRoot, "Child" & $i)
Next

_GUICtrlTreeView_Expand($hTV)

GUISetState()

; Remove checkboxes from children - must be after GUISetState
For $i = 1 to 3
    _GUICtrlTreeView_SetStateImageIndex($hTV, $aItem[$i], 0)
Next

; Remove checkbox from root
;_GUICtrlTreeView_SetStateImageIndex($hTV, $hRoot, 0)

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            ExitLoop
    EndSwitch
WEnd

Thanks for the prod to get it working.

      I'm trying to build a tree view that contains a list of IPs and then when you select one, additional steps are taken with the IP. I found an example of how to read the selected text of a treeview but I keep running into a problem. Sometimes, when I hit the "select" button in my UI, it returns the last record in the list and NOT the record I have selected. The weird part about this is that I've tried this a number of times on several different computers and windows versions and I keep getting the same issue. Sometimes it will ONLY select the last record, sometimes it selects the last record the first time and then starts letting you select, and sometimes it works without issue. Can anyone advise?
      Here is an example code block:
      #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <GUITreeView.au3> NetworkGUI() Func NetworkGUI($parent = 0) $MachineSelectorGUI = GUICreate("Network Check", 616, 500, Default, Default, Default, Default, $parent) $idMachineList = GUICtrlCreateTreeView(16, 16, 584, 420) $btnSelect = GUICtrlCreateButton("Select", 528, 448, 75, 25) ;Menus $mFile = GUICtrlCreateMenu("File") $mSearchForHosts = GUICtrlCreateMenuItem("Search network for hosts", $mFile) GUISetState(@SW_SHOW) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE GUIDelete($MachineSelectorGUI) ExitLoop Case $btnSelect $hItem=0 $hItem=_GUICtrlTreeView_GetSelection($idMachineList) If $hItem <> 0 Then $sSelected=_GUICtrlTreeView_GetText($idMachineList, $hItem) MsgBox(0,"",$sSelected) Else MsgBox(0,"Oops...","Please select a host to check") EndIf Case $mSearchForHosts Local $aMachines[244]=['192.168.1.1', '192.168.1.2', '192.168.1.3', '192.168.1.4',
