GxImage: KeyDown

KeyDown

Occurs when the user presses a key while an object has the focus.



 Event KeyDown(
	  ByRef KeyCode As Integer,
	  ByVal Shift As Integer )

Parameters

KeyCode
A key code, such as vbKeyF1 (the F1 key) or vbKeyHome (the HOME key).
Shift
An integer that corresponds to the state of the SHIFT, CTRL, and ALT keys at the time of the event. The shift argument is a bit field with the least-significant bits corresponding to the SHIFT key (bit 0), the CTRL key (bit 1), and the ALT key (bit 2 ). These bits correspond to the values 1, 2, and 4, respectively. Some, all, or none of the bits can be set, indicating that some, all, or none of the keys are pressed. For example, if both CTRL and ALT are pressed, the value of shift is 6.

Languages

[Visual Basic] Event KeyDown(ByRef KeyCode As Integer, ByVal Shift As Integer)

[Delphi] procedure KeyDown(Sender: TObject; var Key: Word; Shift: TShiftState);

[C++] void OnKeyDown(short FAR* KeyCode, short Shift);

Remarks

[Delphi] The Sender parameter indicates which component received the event and therefore called the handler.
