Detailed Description

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

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.

Constructor & Destructor Documentation

ColorLegend

(

)

Standard constructor.

Contructs a legend object with an axis at the left side. The legend resides in the top-right area and has no caption. Scale numbering is shown.

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	orientation,
		SCALEPOSITION	pos
	)

Sets legend orientation and scale position.

void setLimits	(	double	start,
		double	stop
	)

Sets the limit of the scale.

void setMajors

(

int

majors

)

Sets scale major tics.

void setMinors

(

int

minors

)

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

val

)

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.
