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.

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 )

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:
pattern Index of the event pattern
 
e 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
 
e Key event
Returns:
true if matches
See also:
mouseMatch()

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()

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()

Change one key pattern
Parameters:
