详细描述

A collection of event patterns

QwtEventPattern introduces a level of indirection for mouse and keyboard inputs. Those are represented by symbolic names, so the application code can be configured by individual mappings.

参见: QwtPicker, QwtPickerMachine, QwtPlotZoomer

成员枚举类型说明

◆ KeyPatternCode

enum QwtEventPattern::KeyPatternCode

Symbolic keyboard input codes

Individual settings can be configured using setKeyPattern()

参见: setKeyPattern(), setMousePattern()

枚举值
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

◆ MousePatternCode

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().

参见: initMousePattern(), setMousePattern(), setKeyPattern()

枚举值
MouseSelect1	The default setting for 1, 2 and 3 button mice is: Qt::LeftButton Qt::LeftButton Qt::LeftButton
MouseSelect2	The default setting for 1, 2 and 3 button mice is: Qt::LeftButton + Qt::ControlModifier Qt::RightButton Qt::RightButton
MouseSelect3	The default setting for 1, 2 and 3 button mice is: Qt::LeftButton + Qt::AltModifier Qt::LeftButton + Qt::AltModifier Qt::MidButton
MouseSelect4	The default setting for 1, 2 and 3 button mice is: Qt::LeftButton + Qt::ShiftModifier Qt::LeftButton + Qt::ShiftModifier Qt::LeftButton + Qt::ShiftModifier
MouseSelect5	The default setting for 1, 2 and 3 button mice is: Qt::LeftButton + Qt::ControlButton \| Qt::ShiftModifier Qt::RightButton + Qt::ShiftModifier Qt::RightButton + Qt::ShiftModifier
MouseSelect6	The default setting for 1, 2 and 3 button mice is: Qt::LeftButton + Qt::AltModifier + Qt::ShiftModifier Qt::LeftButton + Qt::AltModifier \| Qt::ShiftModifier Qt::MidButton + Qt::ShiftModifier
MousePatternCount	Number of mouse patterns

构造及析构函数说明

◆ QwtEventPattern()

QwtEventPattern::QwtEventPattern ( )

Constructor

Initializes mouse and key patterns with default settings.

参见: MousePatternCode, KeyPatternCode

成员函数说明

◆ initKeyPattern()

void QwtEventPattern::initKeyPattern ( )

Set default key patterns

参见: KeyPatternCode

◆ initMousePattern()

void QwtEventPattern::initMousePattern ( int numButtons )

Set default mouse patterns depending on the number of mouse buttons

参数

[in] numButtons Number of mouse buttons (<= 3)

参见: MousePatternCode

◆ keyMatch() [1/2]

bool QwtEventPattern::keyMatch	(	const KeyPattern &	pattern,
		const QKeyEvent *	event
	)		const

protectedvirtual

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.

参数

pattern	Key event pattern
event	Key event

返回: true if matches

参见: mouseMatch()

◆ keyMatch() [2/2]

bool QwtEventPattern::keyMatch	(	KeyPatternCode	code,
		const QKeyEvent *	event
	)		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.

参数

[in]	code	Index of the event pattern
[in]	event	Key event

返回: true if matches, false otherwise

参见: mouseMatch()

◆ keyPattern() [1/2]

QVector< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern ( )

Return the key pattern vector

返回: Key pattern vector (mutable)

◆ keyPattern() [2/2]

const QVector< QwtEventPattern::KeyPattern > & QwtEventPattern::keyPattern ( ) const

Return the key pattern vector

返回: Key pattern vector (const)

◆ mouseMatch() [1/2]

bool QwtEventPattern::mouseMatch	(	const MousePattern &	pattern,
		const QMouseEvent *	event
	)		const

protectedvirtual

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.

参数

pattern	Mouse event pattern
event	Mouse event

返回: true if matches

参见: keyMatch()

◆ mouseMatch() [2/2]

bool QwtEventPattern::mouseMatch	(	MousePatternCode	code,
		const QMouseEvent *	event
	)		const

参数

[in]	code	Index of the event pattern
[in]	event	Mouse event

返回: true if matches, false otherwise

参见: keyMatch()

◆ mousePattern() [1/2]

QVector< QwtEventPattern::MousePattern > & QwtEventPattern::mousePattern ( )

Return the mouse pattern vector

返回: Mouse pattern vector (mutable)

◆ mousePattern() [2/2]

const QVector< QwtEventPattern::MousePattern > & QwtEventPattern::mousePattern ( ) const

Return the mouse pattern vector

返回: Mouse pattern vector (const)
