[Gambas-user] TableView Problem

[jose.santos at ...1197...]

Hi Nando. I'm not very sure about your problem.

I'm working in a database application and I've got TableViews that show
perfectly more than 5.000 rows.

This is the code of the _Data event.

' EVENTS.
' ================================================
PUBLIC SUB Table_Data(Row AS Integer, Column AS Integer)
  DIM objColumn AS DYGridColumn

  objColumn = m_columns[Column]

  SELECT CASE m_bytMode
  CASE DYGridModesEnum.DYGridModeBound
    m_rsData.MoveTo(Row)
    m_table.Data.Text = m_rsData[objColumn.DataField]
  CASE DYGridModesEnum.DYGridModeAddItem
    m_table.Data.Text = Split(m_itemList[Row], m_strFieldSeparator)[Column]
  END SELECT

  ' In Boolean Columns, An Icon is shown instead text values.
  IF objColumn.DataType = DYDataTypes.DYBoolean THEN
    IF CBool(CInt(m_table.Data.Text)) THEN
      m_table.Data.Picture = UtilLib.IconOK()
    ELSE
      m_table.Data.Picture = UtilLib.IconCancel()
    ENDIF
    m_table.Data.Text = ""
  ENDIF
END

It can be a bit confussing but it's very simple:
- FIRST SELECT: There are two working states: bounded to a database or AddItem
mode (an Array suplies the info to the TableView).
- Aditionally, For boolean values of the database, the TableView only 
show icons
instead of -1 or 0.

That's all. Hope you find it useful.

Regards.
