The treeview is a SysTreeView32 class. I am using Win32::GuiTest and Win32::API for the calls not supported in Win32::GuiTest. My Win32 programmers reference does not mention any way to enumerate the treeview. I was hoping to find some Win32 API that I could call using the Win32::API module. I have tried GetWindowText and SendMessageA but to no avail. Ultimately I would like to write a sub that returned a hash of the treeview structure.

###############
sub getWindowText{
    my $hwnd = shift || return;
    $GetWindowText ||= new Win32::API("user32", "GetWindowText", ['N',
+ 'P', 'N'], 'N') || return;
    my $title = " " x 1024;
    my $titleLen = 1024;
    my $result = $GetWindowText->Call($hwnd, $title, $titleLen);
    if($result){return substr($title, 0, $result);}
    #if no result send a WM_GetText message to the window
    $WmSendMessage ||= new Win32::API("user32", "SendMessageA", [N, N,
+ N, P],'N') || return;
    my $WM_GETTEXT=13;
    my $text = " " x 2048;
    my $textLen = 2048;
    my $result = $WmSendMessage->Call($hwnd,$WM_GETTEXT, $textLen, $te
+xt);
    if($result){return substr($text, 0, $result);}
    }
