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

Constructor & Destructor Documentation

tlp::GlAxis::GlAxis	(	const std::string &	axisName,
		const Coord &	axisBaseCoord,
		const float	axisLength,
		const AxisOrientation &	axisOrientation,
		const Color &	axisColor,
		const float	axisWidth = 10
	)

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

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

Method to set the axis graduations. No need to call updateAxis after calling this method.

Parameters:

[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.
