Detailed Description

A class to render an axis graduated with string values.

This class allow to draw a nominative axis (i.e. an axis graduated with string values)

Constructor & Destructor Documentation

tlp::GlNominativeAxis::GlNominativeAxis (const std::string & axisName,

const Coord & axisBaseCoord, const float axisLength, const AxisOrientation & axisOrientation, const Color & axisColor) GlNominativeAxis constructor. Build a nominative axis with no graduations (need to call setAxisGraduationsLabels to build them)

Parameters:

axisName the name of the axis the base coord of the axis (if the axis is horizontal, it is the the left end, if vertical it is the
down end) the length of the axis the orientation of the axis, 2
possible values (HORIZONTAL_AXIS or VERTICAL_AXIS) the color of
the axis

Member Function Documentation

Coord tlp::GlNominativeAxis::getAxisPointCoordForValue (std::string value)

Method to get the axis point coordinates associated to string value

Parameters:

value the string value we want to retrieve axis point coordinates

std::string tlp::GlNominativeAxis::getValueAtAxisPoint (const Coord &

axisPointCoord)
Method to get the string value associated to an axis point. Return ''
if there is not.

Parameters:

axisPointCoord the axis point coordinates we want to retrieve the associated string value

void tlp::GlNominativeAxis::setAxisGraduationsLabels (const std::vector<

std::string > & axisGradsLabels, const LabelPosition & labelsPosition) Method to set the axis graduations labels. A call to updateAxis has to be done after calling this method to build or update the axis
graduations. The labels will be placed on the axis in the same order as the vector passed as parameter (from bottom to top if the axis is
vertical, from left to right if it is horizontal).

Parameters:

axisGradsLabels a vector of string containing the graduations labels
labelsPosition the relative position of the axis graduations label. Two possible values : LEFT_OR_BELOW (if the axis is vertical,
labels will be on the left of the axis, otherwise below) or
RIGHT_OR_ABOVE

void tlp::GlNominativeAxis::translate (const Coord & mouvement) [virtual]

translate the composite with children

Reimplemented from tlp::GlAxis.

void tlp::GlNominativeAxis::updateAxis () [virtual]

Method to update the axis drawing. It has to be called when one (or
more) of the setters method above has been used. This method redraw the whole axis and the graduations.

Reimplemented from tlp::GlAxis.
