Detailed Description

The class visualizes a ColorVector together with a scale (axis) and a caption. ColorLegends are vertical or horizontal

---

Member Enumeration Documentation

enum SCALEPOSITION

Possible anchor points for caption and axis.

Enumerator:

Top	scale on top
Bottom	scale on bottom
Left	scale left
Right	scale right

enum ORIENTATION

Orientation of the legend.

Enumerator:

BottomTop	Positionate the legend vertically, the lowest color index is on the bottom.
LeftRight	Positionate the legend horizontally, the lowest color index is on left side.

Member Function Documentation

void draw

(

)

[virtual]

Draws the object. You should not use this explicitely - the function is called by updateGL().

Reimplemented from Drawable.

void setRelPosition	(	Qwt3D::Tuple	relMin,
		Qwt3D::Tuple	relMax
	)

Sets the relative position of the legend inside widget.

void setOrientation	(	ORIENTATION	,
		SCALEPOSITION
	)

Sets legend orientation and scale position.

void setLimits	(	double	start,
		double	stop
	)

Sets the limit of the scale.

void setMajors

(

int

)

Sets scale major tics.

void setMinors

(

int

)

Sets scale minor tics.

void drawScale

(

bool

val

)

[inline]

Sets whether a scale will be drawn.

void drawNumbers

(

bool

val

)

[inline]

Sets whether the scale will have scale numbers.

void setAutoScale

(

bool

val

)

Sets, whether the axis is autoscaled or not.

void setScale

(

Qwt3D::Scale *

scale

)

Sets another scale.

void setScale

(

Qwt3D::SCALETYPE

)

Sets one of the predefined scale types.

void setTitleString

(

QString const &

s

)

Sets the legends caption string.

void setTitleFont	(	QString const &	family,
		int	pointSize,
		int	weight = QFont::Normal,
		bool	italic = false
	)

Sets the legends caption font.
