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.

enum QwtEventPattern::KeyPatternCode

Symbolic keyboard input codes. Individual settings can be configured using setKeyPattern()

enum QwtEventPattern::MousePatternCode

Symbolic mouse input codes. QwtEventPattern implements 3 different settings for mice with 1, 2, or 3 buttons that can be activated using initMousePattern(). The default setting is for 3 button mice.

Individual settings can be configured using setMousePattern().

Number of mouse patterns.

Constructor

See also:

MousePatternCode, KeyPatternCode

Set default mouse patterns.

See also:

KeyPatternCode

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

Parameters:

numButtons Number of mouse buttons ( <= 3 )

See also:

MousePatternCode

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()

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

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()

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.
