Treeview with tooltip

[Jayson]

Hi all,

I got a treeview which load things from an ini but i'm trying to display the tooltip on the subitem only.

I have tried to merge both array but it doesn't work good.

How can I do this because it keep crashing when i'm getting over the main item.

The code :

expandcollapse popup

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

GUICreate("Treview test with Array and ToolTip", 800, 600)

$mainT = GUICtrlCreateTreeView(150, 10, 600, 500)
$Thandle = GUICtrlGetHandle($mainT)

GUISetState()

$var = IniReadSectionNames("DB.ini")

If @error Then
    MsgBox(4096, "", "Error occurred, probably no INI file.")
    Else
    For $i = 1 to $var[0]
        $var1 = IniReadSection("DB.ini", $var[$i])
        $mainTitem = GUICtrlCreateTreeViewItem(($var[$i]), $mainT)

        For $x = 1 to $var1[0][0]
            GUICtrlCreateTreeViewItem(($var1[$x][0]), $mainTitem)
        Next

    Next
EndIf

While 1
    Switch GUIGetMsg()

        Case $GUI_EVENT_CLOSE
            ExitLoop

        Case $GUI_EVENT_MOUSEMOVE
            SetTip()

    EndSwitch
WEnd

Func SetTip()
    If @AutoItX64 Then
        Local $tPoint = DllStructCreate('int X;int Y')
        DllStructSetData ( $tPoint, 'X', MouseGetPos(0))
        DllStructSetData ( $tPoint, 'Y', MouseGetPos(1))
        Local $tPoint64 = DllStructCreate('int64', DllStructGetPtr($tPoint))
        Local $aHwnd = DllCall('user32.dll', 'hwnd', 'WindowFromPoint', 'int64', DllStructGetData($tPoint64, 1))
    Else
        Local $aHwnd = DllCall('user32.dll', 'hwnd', 'WindowFromPoint', 'uint', MouseGetPos(0), 'uint', MouseGetPos(1))
    EndIf
    Switch $aHwnd[0]
        Case $Thandle
            $tMPos = _WinAPI_GetMousePos(True, $aHwnd[0])
            $hItem = _GUICtrlTreeView_HitTestItem($aHwnd[0], DllStructGetData($tMPos, 1), DllStructGetData($tMPos, 2))
            $sText = _GUICtrlTreeView_GetText($aHwnd[0], $hItem)
            $iIndex = _ArraySearch($var1, $sText, 0, 0, 0, 0, 1, 1)
            $sText = $var1[$iIndex][1]
            If $hItem = 0 Then
                ToolTip('')
            Else
                ToolTip($sText)
            EndIf
        Case Else
            ToolTip('')
    EndSwitch
EndFunc

Db.ini :

[[EMBED...]]
SRC=URL of resource to be embedded
WIDTH=Width of area in which to show resource
HEIGHT=Height of area in which to show resource

Thank you ! Edited March 29, 2011 by Jayson

Change this section:

Switch $aHwnd[0]
        Case $Thandle
            $tMPos = _WinAPI_GetMousePos(True, $aHwnd[0])
            $hItem = _GUICtrlTreeView_HitTestItem($aHwnd[0], DllStructGetData($tMPos, 1), DllStructGetData($tMPos, 2))
            $sText = _GUICtrlTreeView_GetText($aHwnd[0], $hItem)
            $iIndex = _ArraySearch($var1, $sText, 0, 0, 0, 0, 1, 0)
            If @error Then Return ; <<<<<<<<<<<<<<<<<<<<<<<<<<<< Add this line
            $sText = $var1[$iIndex][1]
            If $hItem = 0 Then
                ToolTip('')
            Else
                ToolTip($sText)
            EndIf
        Case Else
            ToolTip('')
    EndSwitch

The problem was happening because when you're not over one of the treeview items, it reads the header and the header text isn't in the $var1 array so it comes back with $iIndex = -1.

[Jayson]

Yeah i knew the problem was only the header so I tried to merge the array to make it easier but I gave up because it was too much stuff to add but your answer work very good.

Thank you BrewManNH !!

[BrewManNH]

I'm glad I could help, besides it's fun to try something new.

[Jayson]

Hi again, I ran into another problem/bug?.. Well i'm not sure but i'll explain.

When I am filling the treeview by my ini loaded in array theres only 2 parts working the [A ...] & [AREA ...] subitem displaying tooltip correctly even on duplicated one.

I have not modified any code from the first post but added your line.

[BrewManNH]

I've altered your code so that it will do as you're expecting.

Your original code was only getting the last value of $var1 when it came out of the TV building loop so that is why it wouldn't show tooltips for all of the elements in the TV. I created a new array to grab the current contents of $var1 during each loop and then added the new contents the next time through the loop until it finished. The only thing I didn't account for is if you have elements with the same names, you will get the wrong tooltips because the array search will only return the first item found. You will see that with the tooltip from the onmouseover in section A... will show up for every onmouseover element you have in the treeview, as an example.

[Jayson]

For the elements with the same names I might found a way but its not very efficiency. I've tested by adding a space char (ALT+0160) It does the trick but original space don't.

This way I would get the right tooltip but it will takes some time to change all of them. I'll try to crush my head to find a better way to detect duplicated names.

Thank you for taking your time to help me
