# tlp::GlAxis Class Reference `#include <GlAxis.h>` Inherits tlp::GlComposite. Inherited by tlp::GlNominativeAxis, and tlp::GlQuantitativeAxis. Inheritance diagram for tlp::GlAxis: [legend] Collaboration diagram for tlp::GlAxis: [legend] List of all members. ## Detailed Description A base class to draw an axis with graduations. This class allow to render an axis with graduations. This class is there for code factorisation and should not be used directly. Use derivated classes instead : GlQuantitativeAxis for a numerical graduated axis and GlNominativeAxis for a string graduated axis ## Public Types enum AxisOrientation { HORIZONTAL_AXIS, VERTICAL_AXIS } enum LabelPosition { LEFT_OR_BELOW, RIGHT_OR_ABOVE } ## Public Member Functions GlAxis (const std::string &axisName, const Coord &axisBaseCoord, const float axisLength, const AxisOrientation &axisOrientation, const Color &axisColor) virtual ~GlAxis () Coord getAxisBaseCoord () const float getAxisLength () const std::string getAxisName () const AxisOrientation getAxisOrientation () const float getAxisGradsWidth () const float getSpaceBetweenAxisGrads () const float getLabelHeight () const float getMaxLabelWidth () const Color getAxisColor () const void setAxisName (const std::string &axisName) void setAxisLength (const float axisLength) void setAxisColor (const Color &axisColor) void setAxisGradsWidth (const float axisGradsWidth) void setMaxCaptionWidth (const float maxCaptionWidth) virtual void updateAxis () void setAxisGraduations (const std::vector< std::string > &axisGradsLabels, const LabelPosition &axisGradsLabelsPosition=LEFT_OR_BELOW) void setAxisGraduationsMaxLabelWidth (const float maxWidth) void addCaption (const LabelPosition &captionPos, const float captionHeight, const bool captionFrame=false, const float maxCaptionWidth=0, const float captionOffset=0, const std::string caption="") void translate (const Coord &c) ## Protected Member Functions void computeBoundingBox () virtual Coord computeCaptionCenter () virtual void computeCaptionSize (float height) void addAxisCaption (const Coord &captionLabelCenter, const bool captionFrame) ## Protected Attributes std::string axisName Coord axisBaseCoord float axisLength AxisOrientation axisOrientation Color axisColor float axisGradsWidth float spaceBetweenAxisGrads float captionWidth float captionHeight bool captionFrame std::string captionText float labelHeight float captionOffset GlComposite * axisLinesComposite GlComposite * captionComposite GlComposite * gradsComposite bool captionSet LabelPosition captionPosition float maxCaptionWidth float maxGraduationLabelWidth ## Member Enumeration Documentation

tlp::GlAxis::GlAxis | ( | const std::string & | axisName,
|  | const Coord & | axisBaseCoord,
|  | const float | axisLength,
|  | const AxisOrientation & | axisOrientation,
|  | const Color & | axisColor
| ) |
  | GlAxis constructor Parameters:
  | axisName | the name of the axis
  | axisBaseCoord | the base coord of the axis (if the axis is horizontal, it is the the left end, if vertical it is the down end)
  | axisLength | the length of the axis
  | axisOrientation | the orientation of the axis, 2 possible values (HORIZONTAL_AXIS or VERTICAL_AXIS)
  | axisColor | the color of the axis
virtual tlp::GlAxis::~GlAxis | ( |  | ) | `[virtual]`
| GlAxis destructor
## Member Function Documentation
void tlp::GlAxis::addAxisCaption | ( | const Coord & | captionLabelCenter,
|  | const bool | captionFrame
| ) | `[protected]`
void tlp::GlAxis::addCaption | ( | const LabelPosition & | captionPos,
|  | const float | captionHeight,
|  | const bool | captionFrame = `false`,
|  | const float | maxCaptionWidth = `0`,
|  | const float | captionOffset = `0`,
|  | const std::string | caption = `""`
| ) |
  | Method which adds a caption to the axis. No need to call updateAxis after calling this method. Parameters:
  | captionPos | the relative position of the caption. Two possible values : LEFT_OR_BELOW (if the axis is vertical, caption will be below of the axis, otherwise on the left) or RIGHT_OR_ABOVE
  | captionHeight | the caption text height
  | captionFrame | if true the caption will be framed
  | maxCaptionWidth | fill this parameter if you want to restrain the caption width
  | captionOffset | fill this parameter if you want to fix the offset between the axis and the caption
  | caption | if this parameter is filled, use this value as caption text, otherwise the caption text will be the axis name

void tlp::GlAxis::setAxisColor | ( | const Color & | axisColor | ) | `[inline]`
| Method to set the axis color
void tlp::GlAxis::setAxisGradsWidth | ( | const float | axisGradsWidth | ) | `[inline]`
| Methods to set the axis graduations Width
void tlp::GlAxis::setAxisGraduations | ( | const std::vector< std::string > & | axisGradsLabels,
|  | const LabelPosition & | axisGradsLabelsPosition = `LEFT_OR_BELOW`
| ) |
  | Method to set the axis graduations. No need to call updateAxis after calling this method. Parameters:
  | axisGradsLabels | the labels of the graduations, they will be equally spaced on the axis
  | axisGradsLabelsPosition | the relative position of the axis graduations label. Two possible values : LEFT_OR_BELOW (if the axis is horizontal, labels will be on the left of the axis, otherwise below) or RIGHT_OR_ABOVE

void tlp::GlAxis::translate | ( | const Coord & | c | ) | `[virtual]`
| translate the composite with children Reimplemented from tlp::GlComposite. Reimplemented in tlp::GlNominativeAxis.
virtual void tlp::GlAxis::updateAxis | ( |  | ) | `[virtual]`
| Method to update the axis drawing. It has to be called when one (ore more) of the setters methods above has been used This method erase the whole axis drawing and redraw the axis line and the caption (if any) The axis graduations have to be reset by calling setAxisGraduations Reimplemented in tlp::GlNominativeAxis, and tlp::GlQuantitativeAxis.
