man QwtEventPattern (Fonctions bibliothèques) -

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.

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
