GUITreeViewEx - New Release 11 Jan 15

[RTFC]

@maniootek: Melba is not around this week, so you may have to wait a while for a reply. Just so you know.

maniootek,

You can very easily write a small function to convert an array to a suitably formatted string which the UDF will accept:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <MsgBoxConstants.au3>
#include <String.au3>

#include "GUITreeViewEx.au3"

Global $aTV_List_1[9][3] = [ _
                        ["Food", "Fruit", "Apple"], _
                        ["Food", "Meat", "Steak"], _
                        ["Food", "Meat", "Chicken"], _
                        ["Food", "Dairy", "Cheese"], _
                        ["Drinks", "Water"], _
                        ["Drinks", "Fizzy", "Cola"], _
                        ["Drinks", "Juice", "Orange"], _
                        ["Drinks", "Hot Drinks", "Tea"], _
                        ["Drinks", "Hot Drinks", "Coffee"]]

$sTV_Data_1 = _ConvertArray($aTV_List_1)

Global $aTV_List_2[8][3] = [ _
                        ["A", "AA", "AAA"], _
                        ["A", "AA", "AAB"], _
                        ["B", "BA"], _
                        ["B", "BB", "BBA"], _
                        ["B", "BB", "BBB"], _
                        ["B", "BB", "BBC"], _
                        ["C", "CA"], _
                        ["D", "DA", "DAA"]]

$sTV_Data_2 = _ConvertArray($aTV_List_2)

; Create GUI
Global $hGUI = GUICreate("Test", 500, 500)

; Create TreeView
Global $cTV_1 = GUICtrlCreateTreeView(10, 10, 230, 350, BitOR($GUI_SS_DEFAULT_TREEVIEW, $TVS_CHECKBOXES))

_GUITreeViewEx_LoadTV($cTV_1, $sTV_Data_1)

; Expand TreeView
_GUICtrlTreeView_Expand($cTV_1)

Global $cTV_2 = GUICtrlCreateTreeView(260, 10, 230, 350, BitOR($GUI_SS_DEFAULT_TREEVIEW, $TVS_CHECKBOXES))

_GUITreeViewEx_LoadTV($cTV_2, $sTV_Data_2)

; Expand TreeView
_GUICtrlTreeView_Expand($cTV_2)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

Func _ConvertArray($aTV_List)
    $sString = ""
    $iColCount = UBound($aTV_List, 2)
    Local $aCurrLevel[$iColCount]
    For $i = 0 To UBound($aTV_List) - 1
        For $j = 0 To $iColCount - 1
            If $aTV_List[$i][$j] <> "" And $aTV_List[$i][$j] <> $aCurrLevel[$j] Then
                $aCurrLevel[$j] = $aTV_List[$i][$j]
                $sString &= _StringRepeat("~", $j) & $aTV_List[$i][$j] & "|"
            EndIf
        Next
    Next
    Return StringTrimRight($sString, 1)
EndFunc

But I am not adding that wrapper function to the UDF or I will have to write a conversion function for every imaginable data format. If the user does not like my chosen format for the TreeView loading string then it is up to them to write a wrapper to convert their desired format into the one used by the UDF.

Thank you for your answer. I think this could be most universal function for populating tree view from array.

Anyway, I have started to use your UDF and sometimes when I click on any place on tree view area i got this error:

is it common problem?

I have created sample of my code when this error show up:

#include <Array.au3>
#include "GUITreeViewEx.au3"

$gui = GUICreate("Form1", 343, 520);, 1565, 583)

$button = GUICtrlCreateButton("Populate", 248, 8, 81, 41)
$TreeView1 = GUICtrlCreateTreeView(10, 96, 250, 300, BitOR($GUI_SS_DEFAULT_TREEVIEW,$TVS_CHECKBOXES))
GUISetState(@SW_SHOW)


_GUITreeViewEx_RegMsg()

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case -3 ;$GUI_EVENT_CLOSE
            Exit
        Case $button
            $fill = "Food|~Fruit|~~Apple|~Meat|~~Steak|~~#Chicken|~Dairy|~~Cheese|Drinks|~Water|~Fizzy|~~#Cola|~Juice|~~Orange|~Hot Drinks|~~Tea|~~Coffee"
            PopulateTreeView($fill)
    EndSwitch
    _GUITreeViewEx_AutoCheck()
WEnd

Func PopulateTreeView($sTreeViewFill)
    _GUICtrlTreeView_DeleteAll($TreeView1)
    _GUITreeViewEx_LoadTV($TreeView1, $sTreeViewFill)
    _GUICtrlTreeView_Expand($TreeView1)
    _GUITreeViewEx_InitTV($TreeView1)
EndFunc

I have tried to create script based on your example "GUITreeViewEx_Example_Loop.au3"

any idea what's wrong?

Edit:

I have noticed that problem occur when i press the buttons more than 1 time (pupulatetreeview)

I think I found the problem. I just simple forgot to use _GUITreeViewEx_CloseTV function after use _GUICtrlTreeView_DeleteAll and before I use  _GUITreeViewEx_LoadTV with new data.

[Melba23]

maniootek,

Yes, that is the solution.

[maniootek]

This problem still happens sometimes, I don't know why.

[Melba23]

maniootek,

I have been trying to reproduce the problem without any success. Unless you can provide me with a reproducible series of actions to get the error I am afraid I cannot really do any debugging.

All,

Great UDF once again.

For my need, i merged the three state treeview with this UDF. Fos those interested here is the result.

joiner,

Delighted you find the UDF useful.

Hi Melba,

sorry to jump so late into this topic.

I want to check parent and all children are checked.

If i uncheck a child then, i want the parents to be unchecked.

This i cannot get working.

Thanks for assistance.

Cheers mike

[Melba23]

mike1950r,

And what has this code to do with my UDF? You do not use it at all!

Are you asking if the UDF can help you do as you require? If so, then please provide me with a runnable script showing an example of the treeview you wish to manipulate, including data to fill it.

But I must warn you that I do not believe that the UDF can do what you wish. You imply that unchecking a single child will uncheck the parent - normal practice is to keep the parent ticked unless all the children are unchecked.

Hi Melba,

Thanks anyway.

Hello Melba23, really great UDF. Looks great and works fantastic. However, I would like to select the parent elements with the space key. But then the child elements are no longer automatically selected. Is there a solution for this? Unfortunately I don't know where to start. Thank you in advance.

[Melba23]

Felicitas,

Glad you like it. Try this Beta version: GUITreeViewEx_Test.au3

Good to go?

Hello Melba, sorry for answering so late. Thank you very much, that works wonderfully. From your comment I was also able to see where you did something to the code. This helps me understand it a little better. Thanks
