SetSelectDisplay()
Summary
Controls whether selection operations update maps automatically.
Syntax
SetSelectDisplay(boolean display_flag)
| Argument | Contents |
|---|---|
| display_flag | If "True" all open maps are updated automatically when features are added to or removed from selection sets. If "False" maps are not updated when selection is performed. |
Notes
-
If this flag is set to off, use RedrawMap() to update the map to show current selection settings.
-
Use SetSelectDisplay() when you want to perform a substantial number of selection operations without waiting for the map to update each time.
-
Use SetSelectAutoRedraw() to further control how maps are updated during selection operations.
-
Selection of records that are not map features never updates a map under any circumstances.
Example
qry = "Select * where Age > 65"
SetSelectDisplay("False")
n = SelectByQuery("Elderly", "Several", qry)
ShowMessage("There are " + String(n) + " elderly people in the database.")
DeleteSet("Elderly")
SetSelectDisplay("True")
