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.

MousePatternCode

bool QwtEventPattern::keyMatch (const KeyPattern & pattern, const QKeyEvent * event) 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
event Key event

Returns

true if matches

See also

mouseMatch()

bool QwtEventPattern::keyMatch (KeyPatternCode code, const QKeyEvent * event) 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

code Index of the event pattern
event Key event

Returns

true if matches

See also

mouseMatch()

QVector< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern ()

Returns

Key pattern

const QVector< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern () const

Returns

Key pattern

bool QwtEventPattern::mouseMatch (const MousePattern & pattern, const QMouseEvent * event) 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
event Mouse event

Returns

true if matches

See also

keyMatch()

bool QwtEventPattern::mouseMatch (MousePatternCode code, const QMouseEvent * event) 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
