QwtEventPattern(3) Qwt User's Guide QwtEventPattern(3) NAME QwtEventPattern - A collection of event patterns. SYNOPSIS #include Inherited by QwtPicker. Classes class KeyPattern A pattern for key events. class MousePattern A pattern for mouse events. Public Types enum MousePatternCode { MouseSelect1, MouseSelect2, MouseSelect3, MouseSelect4, MouseSelect5, MouseSelect6, MousePatternCount } Symbolic mouse input codes. enum KeyPatternCode { KeySelect1, KeySelect2, KeyAbort, KeyLeft, KeyRight, KeyUp, KeyDown, KeyRedo, KeyUndo, KeyHome, KeyPatternCount } Symbolic keyboard input codes. Public Member Functions QwtEventPattern () virtual ~QwtEventPattern () Destructor. void initMousePattern (int numButtons) void initKeyPattern () void setMousePattern (MousePatternCode, Qt::MouseButton button, Qt::KeyboardModifiers=Qt::NoModifier) void setKeyPattern (KeyPatternCode, int key, Qt::KeyboardModifiers modifiers=Qt::NoModifier) void setMousePattern (const QVector< MousePattern > &) Change the mouse event patterns. void setKeyPattern (const QVector< KeyPattern > &) Change the key event patterns. const QVector< MousePattern > & mousePattern () const const QVector< KeyPattern > & keyPattern () const QVector< MousePattern > & mousePattern () QVector< KeyPattern > & keyPattern () bool mouseMatch (MousePatternCode, const QMouseEvent *) const Compare a mouse event with an event pattern. bool keyMatch (KeyPatternCode, const QKeyEvent *) const Compare a key event with an event pattern. Protected Member Functions virtual bool mouseMatch (const MousePattern &, const QMouseEvent *) const Compare a mouse event with an event pattern. virtual bool keyMatch (const KeyPattern &, const QKeyEvent *) const Compare a key event with an event pattern. 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.

Member Enumeration Documentation enum QwtEventPattern::KeyPatternCode Symbolic keyboard input codes. Individual settings can be configured using setKeyPattern() See also setKeyPattern(), setMousePattern() Enumerator KeySelect1 Qt::Key_Return. KeySelect2 Qt::Key_Space. KeyAbort Qt::Key_Escape. KeyLeft Qt::Key_Left. KeyRight Qt::Key_Right. KeyUp Qt::Key_Up. KeyDown Qt::Key_Down. KeyRedo Qt::Key_Plus. KeyUndo Qt::Key_Minus. KeyHome Qt::Key_Escape. KeyPatternCount Number of key patterns. Definition at line 112 of file qwt_event_pattern.h. 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(). See also initMousePattern(), setMousePattern(), setKeyPattern() Enumerator MouseSelect1 The default setting for 1, 2 and 3 button mice is: o Qt::LeftButton o Qt::LeftButton o Qt::LeftButton MouseSelect2 The default setting for 1, 2 and 3 button mice is: o Qt::LeftButton + Qt::ControlModifier o Qt::RightButton o Qt::RightButton MouseSelect3 The default setting for 1, 2 and 3 button mice is: o Qt::LeftButton + Qt::AltModifier o Qt::LeftButton + Qt::AltModifier o Qt::MidButton MouseSelect4 The default setting for 1, 2 and 3 button mice is: o Qt::LeftButton + Qt::ShiftModifier o Qt::LeftButton + Qt::ShiftModifier o Qt::LeftButton + Qt::ShiftModifier MouseSelect5 The default setting for 1, 2 and 3 button mice is: o Qt::LeftButton + Qt::ControlButton | Qt::ShiftModifier o Qt::RightButton + Qt::ShiftModifier o Qt::RightButton + Qt::ShiftModifier MouseSelect6 The default setting for 1, 2 and 3 button mice is: o Qt::LeftButton + Qt::AltModifier + Qt::ShiftModifier o Qt::LeftButton + Qt::AltModifier | Qt::ShiftModifier o Qt::MidButton + Qt::ShiftModifier MousePatternCount Number of mouse patterns.
