NAME¶

QwtEventPattern - A collection of event patterns.

SYNOPSIS¶

#include <qwt_event_pattern.h> Inherited by QwtPicker.

Classes¶

class KeyPattern A pattern for key events. class MousePattern A pattern for mouse events.

Public Types¶

enum KeyPatternCode { KeySelect1, KeySelect2, KeyAbort, KeyLeft, KeyRight, KeyUp, KeyDown, KeyRedo, KeyUndo, KeyHome, KeyPatternCount } enum MousePatternCode { MouseSelect1, MouseSelect2, MouseSelect3, MouseSelect4, MouseSelect5, MouseSelect6, MousePatternCount }

Public Member Functions¶

void initKeyPattern () void initMousePattern (int numButtons) bool keyMatch (uint pattern, const QKeyEvent *) const const QwtArray< KeyPattern > & keyPattern () const QwtArray< KeyPattern > & keyPattern () bool mouseMatch (uint pattern, const QMouseEvent *) const const QwtArray< MousePattern > & mousePattern () const QwtArray< MousePattern > & mousePattern () QwtEventPattern () void setKeyPattern (uint pattern, int key, int state=Qt::NoButton) void setKeyPattern (const QwtArray< KeyPattern > &) void setMousePattern (const QwtArray< MousePattern > &) void setMousePattern (uint pattern, int button, int state=Qt::NoButton) virtual ~QwtEventPattern ()

Protected Member Functions¶

virtual bool keyMatch (const KeyPattern &, const QKeyEvent *) const virtual bool mouseMatch (const MousePattern &, const QMouseEvent *) const

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. See also:

Member Function Documentation¶

void QwtEventPattern::initKeyPattern () Set default mouse patterns.¶

See also:

void QwtEventPattern::initMousePattern (intnumButtons) Set default mouse patterns, depending on the number of mouse buttons¶

Parameters: See also:

bool QwtEventPattern::keyMatch (uintpattern, const QKeyEvent *e) 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: Returns: See also:

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: Returns: See also:

const QwtArray< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern () const¶

Return key patterns.

QwtArray< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern ()¶

Return Key patterns.

bool QwtEventPattern::mouseMatch (uintpattern, const QMouseEvent *e) 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: Returns: See also:

bool QwtEventPattern::mouseMatch (const MousePattern &pattern, const QMouseEvent *e) 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: Returns: See also:

QwtArray< QwtEventPattern::MousePattern > & QwtEventPattern::mousePattern ()¶

Return ,ouse patterns.

const QwtArray< QwtEventPattern::MousePattern > & QwtEventPattern::mousePattern () const¶

Return mouse patterns.

void QwtEventPattern::setKeyPattern (uintpattern, intkey, intstate = Qt::NoButton) Change one key pattern¶

Parameters: See also:

void QwtEventPattern::setKeyPattern (const QwtArray< KeyPattern > &pattern)¶

Change the key event patterns.

void QwtEventPattern::setMousePattern (uintpattern, intbutton, intstate = Qt::NoButton) Change one mouse pattern¶

Parameters: See also:
