Detailed Description

A Txq3dLabel is a base class to draw text at a point with respect to the real-world coordinate system using OpenGL.

This class is abstract since it contains a pure virtual method to paint the object.

Constructor & Destructor Documentation

Txq3dLabel::Txq3dLabel ( )

This constructor is default.

Txq3dLabel::Txq3dLabel ( QString thisLabel, double sx, double sy, double sz )

This constructor takes a label and x,y postion. Parameters: thisLabel   the label to draw sx   the x position to place the label sy   the y position to place the label sz   the z position to place the label

Txq3dLabel::~Txq3dLabel ( ) [virtual]

The destructor is default.

Member Function Documentation

void Txq3dLabel::dump ( QTextStream * ts ) [protected, virtual]

Dump the object contents to the text stream ts. Parameters: ts   the text stream to use Reimplemented from TxqDrawable.

QFont Txq3dLabel::getFont ( )

Get the label's font.

double Txq3dLabel::getFontScale ( )

Get the font scaling factor. Returns: the font scaling factor

double Txq3dLabel::getFontThickness ( )

Get the font thickness. Returns: the font thickness

QString Txq3dLabel::getLabel ( )

Get the label. Returns: return the text as a QString. Reimplemented from TxqDrawable.

std::vector< double > Txq3dLabel::getLocation ( )

Get the point in the real-world coordinate system. Returns: the point location as a vector of doubles where the first point is x, the second is y, and the third is z

void Txq3dLabel::paintGL ( ) [pure virtual]

Paints the label text. This method is pure virtual Reimplemented from Txq3dDrawable. Reimplemented in Txq3dFontLabel, and Txq3dStrokeLabel.

void Txq3dLabel::setFont ( QFont f ) [virtual]

Set the font using QFont. Reimplemented in Txq3dFontLabel.

void Txq3dLabel::setFontScale ( double fs )

Set the font scaling factor. Parameters: fs   a font scaling factor

void Txq3dLabel::setFontThickness ( double ft )

Set the font thickness. Parameters: ft   the desired font thickness which will depend on the derived class interpertation of thickness.

void Txq3dLabel::setLabel ( const char * label )

Set the label to draw. Parameters: label   a const char* to represent the text to draw.

void Txq3dLabel::setLabel ( QString label )

Set the label to draw. Parameters: label   the QString representing the text to draw.

void Txq3dLabel::setLocation ( int x, int y ) [inline, virtual]

Overloaded signature to prevent compiler warnings. This should not be used unless one want the Z-value to default to 0.0 Parameters: x   the x location to draw y   the y location to draw Reimplemented from TxqDrawable. Definition at line 91 of file Txq3dLabel.h.

void Txq3dLabel::setLocation ( double x, double y, double z )

Set the point in the real-world coordinate system. Parameters: x   the x location to draw y   the y location to draw z   the z location to draw
