- The QKeyEvent class contains parameters that describe a key
- event.
-
- Key events occur when a key is pressed or released when a
- widget has keyboard input focus.
-
- A key event contains a special accept flag which tells
- whether the receiver wants the key. You should call
- QKeyEvent::ignore() if the key press or release event is not
- handled by your widget.
-
- The QWidget::disable() function disables mouse and keyboard
- events for a widget, and QWidget::enable() enables mouse and
- keyboard events.
-
- The event handlers QWidget::keyPressEvent() and
- QWidget::keyReleaseEvent() receive key events.
-
- See also: QFocusEvent and QWidget::grabKeyboard().
-
- Examples: table/table.cpp picture/picture.cpp

- Constructs a key event object.
-
- The _t_y_p_e parameter must be Event_KeyPress or
- Event_KeyRelease.
-
- If _k_e_y is 0, the event is not a result of a known key (e.g.
- it may be the result of a compose sequence or keyboard
- macro).
-
- The accept flag is set to TRUE.

- Sets the accept flag of the key event object.
-
- Setting the accept parameter indicates that the receiver of
- the event wants the key event. Unwanted key events are sent
- to the parent widget.
-
- The accept flag is set by default.
-
- See also: ignore().

- receiver does not want the key event. Unwanted key events

- The header file qkeycode.h lists the possible keyboard
- codes. These codes are independent of the underlying window
- system.
-
- Key code 0 means that the event is not a result of a known
- key (e.g. it may be the result of a compose sequence or
- keyboard macro).
