Descripción detallada

The Wheel Widget.

The wheel widget can be used to change values over a very large range in very small steps. Using the setMass member, it can be configured as a flywheel.

void QwtWheel::draw	(	QPainter *	p,
		const QRect &	update_rect
	)		`[protected]`

Redraw panel and wheel.

void QwtWheel::drawWheel	(	QPainter *	p,
		const QRect &	r
	)		`[protected]`

Redraw the wheel.

Parámetros:

p	painter
r	contents rectangle

void QwtWheel::drawWheelBackground	(	QPainter *	p,
		const QRect &	r
	)		`[protected]`

Draw the Wheel's background gradient.

void QwtWheel::getScrollMode	(	const QPoint &	p,
		int &	scrollMode,
		int &	direction
	)		`[protected, virtual]`

Determine the scrolling mode and direction corresponding to a specified point.

Parámetros:

Implementa QwtAbstractSlider.

double QwtWheel::getValue ( const QPoint & p ) [protected, virtual]

Determine the value corresponding to a specified point.

Implementa QwtAbstractSlider.

int QwtWheel::internalBorder ( ) const

void QwtWheel::layoutWheel ( bool update = true ) [protected]

Recalculate the slider's geometry and layout based on.

double QwtWheel::mass ( ) const [virtual]

Reimplementado de QwtAbstractSlider.

QSize QwtWheel::minimumSizeHint ( ) const [virtual]

Return a minimum size hint.

Atención:: The return value is based on the wheel width.

Reimplementado de QWidget.

void QwtWheel::paintEvent ( QPaintEvent * e ) [protected, virtual]

Qt Paint Event.

Reimplementado de QWidget.

void QwtWheel::paletteChange ( const QPalette & ) [protected, virtual]

Call update() when the palette changes.

Reimplementado de QWidget.

void QwtWheel::resizeEvent ( QResizeEvent * e ) [protected, virtual]

Qt Resize Event.

Reimplementado de QWidget.

void QwtWheel::setColorArray ( ) [protected]

Set up the color array for the background pixmap.

void QwtWheel::setInternalBorder ( int w )

Set the internal border width of the wheel.

The internal border must not be smaller than 1 and is limited in dependence on the wheel's size. Values outside the allowed range will be clipped.

The internal border defaults to 2.

Parámetros:

w	border width

void QwtWheel::setMass ( double val ) [virtual]

Set the mass of the wheel.

Assigning a mass turns the wheel into a flywheel.

Parámetros:

val	the wheel's mass

Reimplementado de QwtAbstractSlider.

void QwtWheel::setOrientation ( Qt::Orientation o ) [virtual]

Set the wheel's orientation.

Parámetros:

o	Orientation. Allowed values are Qt::Horizontal and Qt::Vertical. Defaults to Qt::Horizontal.

Ver también:: QwtAbstractSlider::orientation()

Reimplementado de QwtAbstractSlider.

void QwtWheel::setTickCnt ( int cnt )

Adjust the number of grooves in the wheel's surface.

The number of grooves is limited to 6 <= cnt <= 50. Values outside this range will be clipped. The default value is 10.

Parámetros:

cnt	Number of grooves per 360 degrees

void QwtWheel::setTotalAngle ( double angle )

Set the total angle which the wheel can be turned.

One full turn of the wheel corresponds to an angle of 360 degrees. A total angle of n*360 degrees means that the wheel has to be turned n times around its axis to get from the minimum value to the maximum value.

The default setting of the total angle is 360 degrees.

Parámetros:

angle total angle in degrees

void QwtWheel::setViewAngle ( double angle )

Specify the visible portion of the wheel.

You may use this function for fine-tuning the appearance of the wheel. The default value is 175 degrees. The value is limited from 10 to 175 degrees.

Parámetros:

angle Visible angle in degrees

void QwtWheel::setWheelWidth ( int w )

Set the width of the wheel.

Corresponds to the wheel height for horizontal orientation, and the wheel width for vertical orientation.

Parámetros:

w	the wheel's width

QSize QwtWheel::sizeHint ( ) const [virtual]

Devuelve:: a size hint

Reimplementado de QWidget.

int QwtWheel::tickCnt ( ) const

double QwtWheel::totalAngle ( ) const

void QwtWheel::valueChange ( ) [protected, virtual]

Notify value change.

Reimplementado de QwtAbstractSlider.

double QwtWheel::viewAngle ( ) const
