Listview.GetSelection strangeness
Posted: Wed May 27, 2026 7:41 pm
I have a multiselect listview and encounter some strangeness.
If I click on an entry for the first time, I get the correct entry from Listview.GetSelection, but if I then click another entry, GetSelection returns the previously clicked entry and not the entry I currently clicked on!?
If I start to select multiple entries, GetSelection returns the correct entries.
But if I then click on another entry (so all selected entries will be deselected), GetSelection returns the previously selected entries.
I know that GetSelection doesn't return the active entry if multiple entries are selected.
If I browse through the listiview by cursor keys and select/deselect some entries everything is returned correct.
Here is short example:

DebugPrint("t[0] = "..IIf(ListItems(t) > 0, t[0], -1)..", isSel = "..dom("lv", "Select", t[0], "Ask"))
DebugPrint("active = "..get("lv", "active"))
For Local i=0 To ListItems(t)-1
DebugPrint("t["..i.."] = "..t[i])
