NAME
QwtEventPattern -
SYNOPSIS
Inherited by QwtPicker.
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.

bool QwtEventPattern::keyMatch (const KeyPattern & pattern, const QKeyEvent
* e) 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
e Key event
Returns:
TRUE if matches
