How to return array's current row?

[qwert]

I don't work with arrays all that often, so please excuse my asking what might be a basic question.

Based on a "root filename", I use the _FileListToArrayRec to locate possible sources of a useful graphic ... which often has several file choices, as shown by the example below.

I can envision a couple of ways to prompt the user (with a dialog) to make a selection, based on found files.

But is there a direct way to know the row the user has clicked on?

Thanks in advance for any help.

make your own listview (as I don't think you can do anything with _arraydisplay's listview) and hunt things about selecting its rows?

Alternatively you could use a ComboBox for example:

expandcollapse popup

#include <Array.au3>
#include <ComboConstants.au3>
#include <File.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>

Example()

Func Example()
    Local $sFolderPath = @ScriptDir
    Local $aFolderPath = _FileListToArrayRec($sFolderPath, '*.ai;*.eps;*.jpg;*.gif;*.png', 1, 1, 0, 1)
    ; Create a GUI with various controls.
    Local $hGUI = GUICreate("Example", 300, 200)

    ; Create a combobox control.
    Local $idComboBox = GUICtrlCreateCombo("Please Select an Image", 10, 10, 185, 20, $CBS_DROPDOWNLIST)
    Local $idSelect = GUICtrlCreateButton("Select", 200, 9, 90, 23)
    Local $idClose = GUICtrlCreateButton("Close", 210, 170, 85, 25)

    ; Add additional items to the combobox.
    GUICtrlSetData($idComboBox, _ArrayToString($aFolderPath, '|', 1))

    ; Display the GUI.
    GUISetState(@SW_SHOW, $hGUI)

    Local $sComboRead = ""

    ; Loop until the user exits.
    While 1
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE, $idClose
                ExitLoop
            Case $idSelect
                If FileExists($sFolderPath & '\' & GUICtrlRead($idComboBox)) Then
                    ShellExecute($sFolderPath & '\' & GUICtrlRead($idComboBox))
                EndIf
        EndSwitch
    WEnd

    ; Delete the previous GUI and all controls.
    GUIDelete($hGUI)
EndFunc   ;==>Example

Well, after what I can only describe as a learning experience, I opted to use AddItem.  (AddArray turned into a confusing exercise of trying to use the indices right in the arrays.)  The following statements worked ... and I ended up with a very sensible, scrollable panel of found files.

If IsArray($array) Then
    For $i = 1 to $array[0] Step 1
    _GUICtrlListView_AddItem($ListView, $array[$i])
    Next
EndIf

The combo box method will be a handy alternative.

Thanks for both responses.

From the Help file about _ArrayDisplay:

Run User Func
Run the user-defined function passed in $hUser_Function. This function is entirely separate from the UDF and must be created and coded by the user to accept 2 (and only 2) parameters which will be provided by the UDF itself: the full array being displayed and a 1D array holding the selected rows indices with a count in the [0] element. These parameters can then be used inside the user function as required. The button is not displayed if no function is specified.

And the code:

#include <Array.au3>

Global $aSelRows
Global $aArray[10][6]
For $i = 0 To 9
  For $j = 0 To 5
    $aArray[$i][$j] = $i & "/" & $j
  Next
Next
_ArrayDisplay( $aArray, "Select one/more items. Click ""Run User Func""", "", 0, Default, Default, Default, Default, GetSelected )

Func GetSelected( $aArray, $aSelected )
  $aSelRows = $aSelected
  If $aSelRows[0] = 0 Then
    MsgBox( 0, "", "Select one/more items. Click ""Run User Func""" )
  Else
    MsgBox( 0, "", $aSelRows[0] & " items selected" )
    Send( "{ESC}" )
  EndIf
EndFunc

_ArrayDisplay( $aSelRows )

@LarsJ: Thanks for reminding me of that method. I recall using something similar 4 or 5 years ago. I'm sure it will come in handy, again.  But for now, I'm firmly on the ListView track for this project ... and learning more every day.
