The OnKeyPress event is the simplest of the three events, in that it returns only a single character the user presses. The character must fall within the ASCII character set. OnKeyPress interprets key combinations only insofar as they evaluate to a single ASCII-character. So, for example, OnKeyPress recognizes the result of Shift+A (a capital 'A'), but not the individual keys pressed. OnKeyPress does not otherwise evaluate keys combinations, and does not recognize function keys or non-ASCII keys such as Ctrl, Alt, Insert, Page Down, and so on. Default or Cancel buttons in the form will intercept the Enter and Escape key press for both the OnKeyPress and OnKeyDown events, (unless used in combination with Alt for the OnKeyDown.) |
По русски говоря OnKeyPress предназначен только для обработки "печатных" символов. Если нужно "непечатные"( не путать с матом
) используют OnKeyDown. Enter и Escape перехватываются и OnKeyPress и OnKeyDown
