Specifies whether a form's KeyPress event intercepts the KeyPress events of a control. Available at design time and run time.
Syntax
Object.KeyPreview[ = lExpr]
Settings
lExpr
The settings for the KeyPreview property are:
| Setting | Description |
| True (.T.) | The form receives KeyPress events first and then the active control receives KeyPress events. |
| False (.F.) | (Default) The active control receives Keypress events; the form doesn't. |
Remarks
The KeyPreview property is used to allow the form to handle KeyPress events before the active control processes them.
You can use this property to create a keyboard-handling procedure for a form. For example, when an application uses function keys, you can process the keystrokes at the form level rather than writing code for each control that can receive keystroke events.
If a form has no visible and enabled controls, it automatically receives all keyboard events.
