When selecting a list item, ensure it is visible

Hi,
Currently, if you use SetGadgetState() to select an item in a list box that is not currently visible (ie further up or down in the list so not in the visible view of the list gadget), it is not scrolled into view
Could this be changed so that even if the row is not visible, it is made visible (brought into focus) when selected programatically
Thanks

Could you post a small snippet ?

Any progress on this request?
It's really annoying using AddGadgetItem() on a big list and the ListIconGadget resets itself to the beginning every time.

obviously my code I'm referring to above has been deleted.
For this reason here once again:
Code: Select all
If OpenWindow(0, 0, 0, 270, 140, "ListViewGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ListViewGadget(0, 10, 10, 250, 120)
For a = 1 To 12
AddGadgetItem (0, -1, "Item " + Str(a) + " of the Listview")
Next
SetGadgetState(0, 10)
EndIf

Hi Peter,
Your code demonstrated the problem. The item is highlighted but is not in view. You have to scroll down to see the highlighted item.

Yeah, that was the plan.
Fred wanted to have a code snippet and now he has it (again).

Is there already a solution? Maybe a workaround?
Strangely enough, it works within a larger web project. Unfortunately, I can't reproduce what's the reason it works.
