Member Enumeration Documentation

◆ Orientation

enum ACG::QtWidgets::QtWheel::Orientation

Orientation of the widget.

Definition at line 107 of file QtWheel.hh.

Constructor & Destructor Documentation

◆ QtWheel()

ACG::QtWidgets::QtWheel::QtWheel	(	QWidget *	_parent = `0`,
		const char *	_name = `0`,
		Orientation	_orientation = `Horizontal`
	)

Constructor.

Definition at line 77 of file QtWheel.cc.

◆ ~QtWheel()

virtual

Destructor.

Definition at line 106 of file QtWheel.cc.

Member Function Documentation

◆ angle()

double ACG::QtWidgets::QtWheel::angle ( ) const

inline

get current angle of the wheel (radiants, unbounded, cf. clip())

Definition at line 134 of file QtWheel.hh.

◆ angleChangedBy

void ACG::QtWidgets::QtWheel::angleChangedBy ( double _angle )

signal

The angle chaned by the relative _angle (cf. clip()).

Note: Do not use this signal together with angleChangedBy()! The reason for this is that you cannot be sure in which order the you get the signals!

If you need both values the angle and the relative difference then use this signal and angle() or angleChangedTo() and diffAngle() respectively!

◆ angleChangedTo

void ACG::QtWidgets::QtWheel::angleChangedTo ( double _angle )

signal

The angle changed to the absolute _angle (cf. clip()). Note: Do not use together with angleChangedBy() (see there)!

◆ clip()

double ACG::QtWidgets::QtWheel::clip ( double _angle )

static

Clips _angle to range [0,2pi[. All angle()s provided by this widget are unbounded in a sense that a full turn of the wheel is 2pi not 0. As a consequence two full turns are 4pi, etc.

This methods clips the angle again [0,2pi[

See also: deg()

Definition at line 436 of file QtWheel.cc.

◆ deg()

double ACG::QtWidgets::QtWheel::deg ( double _angle )

static

maps _angle from radiants to degrees (works also for clip()ped angles)

Definition at line 440 of file QtWheel.cc.

◆ diffAngle()

double ACG::QtWidgets::QtWheel::diffAngle ( ) const

inline

Get difference angle. You may call this method from a slot connected to angleChangedTo() and obtain the difference angle (equal to the argument to angleChangedBy()).

Definition at line 144 of file QtWheel.hh.

Definition at line 182 of file QtWheel.hh.

◆ gearUp

void ACG::QtWidgets::QtWheel::gearUp ( )

signal

The gear() has been "shifted" by double clicking the widget. Up-shifting will double the value of gear(). The signal is emitted after gear() has been changed.

◆ setAngle()

void ACG::QtWidgets::QtWheel::setAngle ( double _angle )

inline

set current angle of the wheel (radiants, unbounded, cf. clip())

Definition at line 136 of file QtWheel.hh.

◆ setGear()

void ACG::QtWidgets::QtWheel::setGear ( double _g )

inline

How fast does angle() changed when the wheel is turned? The default setting is 1.0. Then angle() will be changed by pi (180 degrees) when dragging the wheel from one end of the widget to the other. In general this angular difference will be multiplied by gear(), i.e. for values >1,0 the angle changes faster.

Definition at line 180 of file QtWheel.hh.

◆ setTracking()

void ACG::QtWidgets::QtWheel::setTracking ( bool _b )

inline

Enables wheel tracking (default: true)

If tracking is enabled, then the QtWheel emits signals whenever the it is dragged. Otherwise signals are emitted only when a dragging process is finished.
