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.

MousePatternCode

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 \fBKeyPattern\fP &pattern, const QKeyEvent *e) const\fC [protected]\fP, \fC [virtual]\fP

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 \fBMousePattern\fP &pattern, const QMouseEvent *e) const\fC [protected]\fP, \fC [virtual]\fP

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
