[Gambas-user] How to sort a TableView?

[Gianluigi]

Without using the database, have taught me so:

Public Sub TableView1_Sort()
   Dim Values, ValueSorted As New String[]
   Dim Nx, iNx As Integer
   Dim tmp As String

    For Nx = 0 To TableView1.Rows.Max
      Values.Add(TableView1[Nx, TableView1.Columns.Sort].Text)
    Next
    ValueSorted = Values.Copy()
    ValueSorted.Sort(TableView1.Columns.Ascending)
    For Nx = 0 To ValueSorted.Max
      For iNx = 0 To TableView1.Columns.Max
        Swap TableView1[Nx, iNx].Text,
TableView1[Values.Find(ValueSorted[Nx], 0, Nx), iNx].Text
      Next
      Values.Clear()
      For iNx = 0 To TableView1.Rows.Max
        Values.Add(TableView1[iNx, TableView1.Columns.Sort].Text)
      Next
    Next
    TableView1.Refresh()
End
