Listview Quirk?

6 posts in this topic

I have a Listview that I am trying to move a -1 in to. It displays as a blank. I can move a -1, -2, -3, -4, -5 to it and it displays fine. I just can't move a -1 to it. No errors. It just won't display as a -1. It displays empty.

Trax,

A reproducer script would be helpful - otherwise we are just guessing. ;)

Here you go. I am bug eyed. I spent all weekend on this and got nowhere. I even tried putting a direct "-1" in rather then a variable and it still displayed as blank. I am doing something really stupid. I just don't see it.

Thanks!

From the Help file for _GUICtrlListView_SetItem:

 

If a notification callback is needed, you have to specify $sText = -1

So it looks as if setting the $sText parameter to -1 in that function is a special case and so will not be honoured. But why are you using that function in the first place? It is designed to alter the item attributes which is not what you are doing. So why not just set the values directly?

For $Index = 0 To $NumCars
    _GUICtrlListView_AddItem($List1, $CarData[$Index][0])
    _GUICtrlListView_AddItem($List2, $CarData[$Index][1])
    _GUICtrlListView_AddItem($List3, $CarData[$Index][2])
Next
MsgBox(0, "", "GUI Filled")
; For $Index = 0 To $NumCars
;   _GUICtrlListView_SetItem($List1, $CarData[$Index][0], $Index)
;   _GUICtrlListView_SetItem($List2, $CarData[$Index][1], $Index)
;   _GUICtrlListView_SetItem($List3, $CarData[$Index][2], $Index)
; Next
MsgBox(0, "", "GUI DOne")
You are doing nothing more in your second loop. ;)

And why on earth are you setting the items 1-9 to negative values anyway? :wacko:

I reworked the original code to make is as short as possible for posting. I don't AddItem and SetIitem back to back as displayed above. I AddItems there and throughout the program use SetItem to update it as needed.

I need a flag to specify that the RPM has not been retreived yet. A -1 seemed to be a good flag for that. The -2 thru -9 were just used to show that other negitive numbers could be put in that list. Since -1 isn't allowed I'll change the flag to -99

Thanks!
