Treeview and GUICtrlSetOnEvent

[PaulDG]

Is there anyway to define a GUICtrlSetOnEvent to trigger on any treeview action?

I am using on even mode and would like to execute a function on any treeview focus, not checkboxes but focus IE When i click on the item or subitem.

I have searched for ages and come up with nothing. But i could be blinded by the trees...

Thanks

here's an example converted to events

expandcollapse popup

#include <GUIConstants.au3>
Opt("GUIOnEventMode",1)
GUICreate("My GUI with treeview",350,212)

$treeview = GUICtrlCreateTreeView (6,6,100,150,BitOr($TVS_HASBUTTONS,$TVS_HASLINES,$TVS_LINESATROOT,$TVS_DISABLEDRAGDROP,$TVS_SHOWSELALWAYS),$WS_EX_CLIENTEDGE)
$generalitem = GUICtrlCreateTreeViewitem ("General",$treeview)
GUICtrlSetOnEvent($generalitem,"_ItemsSelected")
$displayitem = GUICtrlCreateTreeViewitem ("Display",$treeview)
GUICtrlSetOnEvent($displayitem,"_ItemsSelected")
$aboutitem = GUICtrlCreateTreeViewitem ("About",$generalitem)
GUICtrlSetOnEvent($aboutitem,"_ItemsSelected")
$compitem = GUICtrlCreateTreeViewitem ("Computer",$generalitem)
GUICtrlSetOnEvent($compitem,"_ItemsSelected")
$useritem = GUICtrlCreateTreeViewitem ("User",$generalitem)
GUICtrlSetOnEvent($useritem,"_ItemsSelected")
$resitem = GUICtrlCreateTreeViewitem ("Resolution",$displayitem)
GUICtrlSetOnEvent($resitem,"_ItemsSelected")
$otheritem = GUICtrlCreateTreeViewitem ("Other",$displayitem)
GUICtrlSetOnEvent($otheritem,"_ItemsSelected")

$startlabel = GUICtrlCreateLabel ("TreeView Demo",190,90,100,20)
$aboutlabel = GUICtrlCreateLabel ("This little scripts demonstates the using of a treeview-control.",190,70,100,60)
GUICtrlSetState(-1,$GUI_HIDE)
$compinfo = GUICtrlCreateLabel ("Name:" & @TAB & @ComputerName & @LF & "OS:" & @TAB & @OSVersion & @LF & "SP:" & @TAB & @OSServicePack,120,30,200,80)
GUICtrlSetState(-1,$GUI_HIDE)

$okbutton = GUICtrlCreateButton ("OK",100,185,70,20)
$cancelbutton = GUICtrlCreateButton ("Cancel",180,185,70,20)
GUICtrlSetOnEvent($cancelbutton,"_Exit")

GUISetState ()
While 1
    Sleep ( 250 )
WEnd

GUIDelete()
Exit

Func _ItemsSelected()
    Select
        Case @GUI_CtrlId = $generalitem
            GUIChangeItems($aboutlabel,$compinfo,$startlabel,$startlabel)
        
        Case @GUI_CtrlId = $aboutitem
            GUICtrlSetState ($compinfo,$GUI_HIDE)
            GUIChangeItems($startlabel,$startlabel,$aboutlabel,$aboutlabel)
            
        Case @GUI_CtrlId = $compitem
            GUIChangeItems($startlabel,$aboutlabel,$compinfo,$compinfo)
    EndSelect
EndFunc

Func _Exit()
 Exit
EndFunc

Func GUIChangeItems($hidestart,$hideend,$showstart,$showend)
    Local $idx
    
    For $idx = $hidestart To $hideend
        GUICtrlSetState ($idx,$GUI_HIDE)
    Next
    For $idx = $showstart To $showend
        GUICtrlSetState ($idx,$GUI_SHOW)
    Next    
EndFunc

So for every treeviewitem i have to set an onevent as well, Thats gonna mean 60 to 100 onevents. I hope that wont be an issue.

Its a shame we cant set an onevent on the parent treeview, it would save alot of code and probably memory.

Oh well, Thanks for the example.

I tried on event on the treeview itself, but didn't work, but here's a twist to the previous example:

expandcollapse popup

#include <GUIConstants.au3>
opt("GUIOnEventMode", 1)
GUICreate("My GUI with treeview", 350, 212)
Local $a_ids[7]
$treeview = GUICtrlCreateTreeView(6, 6, 100, 150, BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS), $WS_EX_CLIENTEDGE)
$a_ids[0] = GUICtrlCreateTreeViewItem("General", $treeview)
$a_ids[1] = GUICtrlCreateTreeViewItem("Display", $treeview)
$a_ids[2] = GUICtrlCreateTreeViewItem("About", $a_ids[0])
$a_ids[3] = GUICtrlCreateTreeViewItem("Computer", $a_ids[0])
$a_ids[4] = GUICtrlCreateTreeViewItem("User", $a_ids[0])
$a_ids[5] = GUICtrlCreateTreeViewItem("Resolution", $a_ids[1])
$a_ids[6] = GUICtrlCreateTreeViewItem("Other", $a_ids[1])

For $x = 0 To UBound($a_ids) - 1
    GUICtrlSetOnEvent($a_ids[$x], "_ItemsSelected")
Next

$startlabel = GUICtrlCreateLabel("TreeView Demo", 190, 90, 100, 20)
$aboutlabel = GUICtrlCreateLabel("This little scripts demonstates the using of a treeview-control.", 190, 70, 100, 60)
GUICtrlSetState(-1, $GUI_HIDE)
$compinfo = GUICtrlCreateLabel("Name:" & @TAB & @ComputerName & @LF & "OS:" & @TAB & @OSVersion & @LF & "SP:" & @TAB & @OSServicePack, 120, 30, 200, 80)
GUICtrlSetState(-1, $GUI_HIDE)

$okbutton = GUICtrlCreateButton("OK", 100, 185, 70, 20)
$cancelbutton = GUICtrlCreateButton("Cancel", 180, 185, 70, 20)
GUICtrlSetOnEvent($cancelbutton, "_Exit")

GUISetState()
While 1
    Sleep(250)
WEnd

GUIDelete()
Exit

Func _ItemsSelected()
    For $x = 0 To UBound($a_ids) - 1
        If BitAND($GUI_FOCUS, GUICtrlRead($a_ids[$x]), $GUI_FOCUS) Then
            $tmp = GUICtrlRead($a_ids[$x], 1)
            If $x = 0 Then
                GUIChangeItems($aboutlabel, $compinfo, $startlabel, $startlabel)
            ElseIf $x = 2 Then
                GUICtrlSetState($compinfo, $GUI_HIDE)
                GUIChangeItems($startlabel, $startlabel, $aboutlabel, $aboutlabel)
            ElseIf $x = 3 Then
                GUIChangeItems($startlabel, $aboutlabel, $compinfo, $compinfo)
            EndIf
        EndIf
    Next
EndFunc  ;==>_ItemsSelected

Func _Exit()
    Exit
EndFunc  ;==>_Exit

Func GUIChangeItems($hidestart, $hideend, $showstart, $showend)
    Local $idx
    
    For $idx = $hidestart To $hideend
        GUICtrlSetState($idx, $GUI_HIDE)
    Next
    For $idx = $showstart To $showend
        GUICtrlSetState($idx, $GUI_SHOW)
    Next
EndFunc  ;==>GUIChangeItems

Thanks again for the example, thats the way ill have to go.

I wonder if thats a limitation, Intended or a bug (onevent on treeview control not working that is)
