Problem with Treeview, $TVS_CHECKBOXES and $TVS_HASBUTTONS

[Vier]

I have a treeview with this two options : $TVS_CHECKBOXES,$TVS_HASBUTTONS.

An exemple :

I create a function for :

- if all child box is check, parent box is check

- if all or one child box is uncheck, parent box is unchek

- if parent box is check, all child box is check

- if parent box is uncheck, all child box is uncheck

My part of function test if parent box is check or uncheck and check/uncheck child box :

For $i = 1 to $tree[0][0][0] ; test all TreeView

If $msg = $tree[$i][0][0] Then ; Parent Treeviewitem

If BitAnd(GUICtrlRead($tree[$i][0][0]),$GUI_CHECKED) Then

For $j = 1 To $tree[$i][0][3]

GUICtrlSetState ($tree[$i][$j][0],$GUI_CHECKED) ; Child TreeviewItem

Next

ElseIf BitAnd(GUICtrlRead($tree[$i][0][0]),$GUI_UNCHECKED) Then

For $j = 1 To $tree[$i][0][3]

GUICtrlSetState ($tree[$i][$j][0],$GUI_UNCHECKED) ; Child TreeviewItem

Next

EndIf

EndIf

Next

My problem : if I collapse/expand with $TVS_HASBUTTONS, my function test if parent box is check/uncheck and check/uncheck child box. But I don't want when I collpase/expand treeview the test works !

Please help me !

Can you also post the code you used to generate your treeview?

I need to create something very similar and I don't quite know how to do so.

Thanks!

I'm use a system with read an ini file, like :

Func _PersoReseauCreateTree3($ini,$name,$tree2)

$ctree = IniReadSection($ini,$name)

$a = $ctree[0][0]

$b = 0

For $i = 1 To $a

$ctree2 = IniReadSection($ini,$ctree[$i][1])

If $ctree2[0][0] > $b Then $b = $ctree2[0][0]

Next

Dim $ctree3[$a+1][$b+1][4]

$ctree3[0][0][0]=$a

For $i = 1 To $a

$ctree2 = IniReadSection($ini,$ctree[$i][1])

$ctree3[$i][0][3] = $ctree2[0][0]

Next

For $i = 1 To $ctree3[0][0][0]

$ctree3[$i][0][0] = GUICtrlCreateTreeViewitem ($ctree[$i][1],$tree2)

$ctree2 = IniReadSection($ini,$ctree[$i][1])

For $j = 1 To $ctree3[$i][0][3]

$ctree3[$i][$j][0] = GUICtrlCreateTreeViewitem (IniRead($ini,$ctree2[$j][1],"c",""),$ctree3[$i][0][0])

$ctree3[$i][$j][1] = IniRead($ini,$ctree2[$j][1],"k","")

$ctree3[$i][$j][2] = IniRead($ini,$ctree2[$j][1],"d","")

Next

Next

Return $ctree3

EndFunc

I had a similar issue. What I did was create an Global array to hold the current state of the upper level items. Then, I set the items state value when it is checked or unchecked. Then, before I check/uncheck the child objects, I see if the state actually changed for the parent item before changing them.

If BitAND(GUICtrlRead(@GUI_CtrlID), $GUI_CHECKED) = $GUI_CHECKED And $catStates[$catCounter] <> BitAND(GUICtrlRead(@GUI_CtrlID), $GUI_CHECKED) Then
                $catStates[$catCounter] = BitAND(GUICtrlRead(@GUI_CtrlID), $GUI_CHECKED)
                GUICtrlSetState($packElements[$packCounter], $GUI_CHECKED)

This isn't really what my code looks like exactly, but I pasted the parts that were relevant.

I have found a solution for my problem : I remove parent checkbox.

For this I have found in the forum a function.
