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.

Member Function Documentation

void QwtEventPattern::initKeyPattern ()

Set default mouse patterns.

See also:

KeyPatternCode

void QwtEventPattern::initMousePattern (int numButtons)

Set default mouse patterns, depending on the number of mouse buttons

Parameters:

numButtons Number of mouse buttons ( <= 3 )

See also:

MousePatternCode

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()

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()

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

Returns:

Key pattern

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

Returns:

Key pattern

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:

code Index of the event pattern
event Mouse event

Returns:

true if matches

See also:

keyMatch()

bool QwtEventPattern::mouseMatch (const MousePattern & pattern, constQMouseEvent * 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
