Parameters
| Parameters | Description |
| Sender: TObject | Originator of the call. This is either the edit control or the inspector. |
| var Key: Word | The key on the keyboard. For non-alphanumeric keys, you must use WinAPI virtual key codes to determine the key pressed. For more information, search for virtual key codes in the Win32 Developer's Reference (WIN32.HLP). |
| Shift: TShiftState | Indicates whether the Shift, Alt, or Ctrl keys are combined with the keystroke. |
Description
EditKeyDown is the OnKeyDown handler for the edit control. On entry to the method the Sender property is checked. If it is not set to the inspector, the method was indeed called from the edit control. Execution is transferred to the inspector. If the call originated from the inspector (Sender is set to Inspector), the item editor keys are processed. This means the keys for Apply, Undo, select prior value, select next value and to invoke the Edit method are checked. Descendants that override this should call inherited and only process special keys if Sender is set to Inspector (so that the inspector had a change to process its own keys first).
