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.

KeyPatternCode
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()
const QwtArray< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern () const
Return key patterns.
QwtArray< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern ()
Return Key patterns.
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
e Mouse event- Returns:
true if matches
- See also:
keyMatch()
QwtArray< QwtEventPattern::MousePattern > & QwtEventPattern::mousePattern ()
Return ,ouse patterns.
const QwtArray< QwtEventPattern::MousePattern > & QwtEventPattern::mousePattern () const
Return mouse patterns.
void QwtEventPattern::setKeyPattern (uintpattern, intkey, intstate = Qt::NoButton) Change one key pattern
- Parameters:
pattern Index of the pattern
key Key
state State- See also:
QKeyEvent
void QwtEventPattern::setKeyPattern (const QwtArray< KeyPattern > &pattern)
Change the key event patterns.
void QwtEventPattern::setMousePattern (const QwtArray< MousePattern > &pattern)
Change the mouse event patterns.
