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:
e Key event
Returns:

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:
e Key event
Returns:
