TDBComboBox.KeyPress procedure
Applies standard keystrokes to the control.
Declaration
procedure KeyPress(var Key: char); overrideArguments
Key | Keystroke character examined in the method. |
Description
KeyPress is an overridden method used to apply standard keystrokes
to the data-aware control. KeyPress calls the inherited method to process the
keystroke character in
Key. If the key is not handled in the
ancestor, and is in the range #32..#255, it can be potentially applied to the
Field in the linked dataset. FieldCanAcceptKey, in the
implementation section, is called to to determine if the keystroke can be
used and applied to the field type. When valid for the field, Key is set to
#0 to suppress further processing of the keystroke.
