Detailed Description
A collection of event patterns.
QwtEventPattern introduces an level of indirection for mouse and
keyboard inputs. Those are represented by symbolic names, so the
application code can be configured by individual mappings.

bool QwtEventPattern::keyMatch (uintpattern, const QKeyEvent *e) const
Compare a key event with an event pattern. A key event matches the
pattern when both have the same key value and in the state value the
same key flags (Qt::KeyButtonMask) are set.
Parameters:
pattern Index of the event pattern
e Key event
Returns:
true if matches
See also:
mouseMatch()
bool QwtEventPattern::keyMatch (const KeyPattern &pattern, const QKeyEvent
*e) const [protected], [virtual]
Compare a key event with an event pattern. A key event matches the
pattern when both have the same key value and in the state value the
same key flags (Qt::KeyButtonMask) are set.
Parameters:
pattern Key event pattern
e Key event
Returns:
true if matches
See also:
mouseMatch()
bool QwtEventPattern::mouseMatch (uintpattern, const QMouseEvent *e) const
Compare a mouse event with an event pattern. A mouse event matches the
pattern when both have the same button value and in the state value the
same key flags(Qt::KeyButtonMask) are set.
Parameters:
pattern Index of the event pattern
e Mouse event
Returns:
true if matches
See also:
keyMatch()
bool QwtEventPattern::mouseMatch (const MousePattern &pattern, const
QMouseEvent *e) const [protected], [virtual]
Compare a mouse event with an event pattern. A mouse event matches the
pattern when both have the same button value and in the state value the
same key flags(Qt::KeyButtonMask) are set.
Parameters:
pattern Mouse event pattern
