Member Function Documentation

draw()

void Drawable::draw ( )

virtual

Reimplemented in Qwt3D::Axis, Qwt3D::ColorLegend, Qwt3D::CoordinateSystem, and Qwt3D::Label.

relativePosition()

Triple Drawable::relativePosition

(

Qwt3D::Triple

rel

)

Calculates world coordinates from relative viewport position.

Parameters

rel	Relative position in viewport coordinates

Returns

Corresponding world coordinates

Warning

Don't rely on (use) this in display lists!

setColor() [1/2]

void Drawable::setColor ( double  r, double  g, double  b, double  a = 1  )

virtual

Reimplemented in Qwt3D::Label.

setColor() [2/2]

virtual

Reimplemented in Qwt3D::Label.

ViewPort2World()

Triple Drawable::ViewPort2World ( Qwt3D::Triple  win, bool *  err = nullptr  )

protected

Converts viewport coordinates to world coordinates (glUnProject)

Parameters

	win	Viewport (window) coordinates
[out]	err	Optional error flag (true on failure)

Returns

World (object) coordinates

Warning
