Detailed Description

PfWidget class.

Wraps Performer calls in a Qt widget so it can be used in Qt user interfaces. Note that this probably does not give the best performance possible since it's triggered from the Qt event loop.

Constructor & Destructor Documentation

PfWidget::PfWidget	(	QWidget *	parent = `NULL`,
		const char *	name = `"PfWidget"`
	)

Constructor.

Calls pfInit if not already initialized.

Member Function Documentation

void PfWidget::setChannel ( pfChannel * chan )

Set channel.

Parameters:

chan	pfChannel to use. This cannot be changed after the window is opened.

void PfWidget::setFrameTime ( int t ) [slot]

Set frame timer in milliseconds.

Parameters:

t	Update rate in milliseconds. This parameter determines how often the scene is redrawn.

void PfWidget::setNearFar	(	float	neardist,
		float	fardist
	)		`[slot]`

Set near/far clipping planes.

Parameters:

near	Near clipping plane.
far	Far clipping plane.

void PfWidget::setPipeNum ( int pipeNum )

Set pipe number.

Parameters:

pipeNum Pipe number to open the window on. This cannot be changed after the window is opened.

void PfWidget::setPipeWindow ( pfPipeWindow * pipeWin )

Set pipe window.

Parameters:

pipeWin pfPipeWindow to use. This cannot be changed after the window is opened.

void PfWidget::setScene ( pfScene * scene )

Set scene.

If none is given before it is needed a default scene with a single light will be created.

Parameters:

scene pfScene to use. This can be changed after the window is opened :-)

void PfWidget::setView	(	float	azim,
		float	elev,
		float	dist = `0.0f`
	)		`[slot]`

Set viewer position by azimuth/elevation/distance angles.

Parameters:

azim	Azimuth angle in degrees, where 0=N, 90=E, 180=S, 270=W.
elev	Height angle in degrees.
dist	Distance from center. If this is =< 0.0 then the radius of the scene's bounding sphere is used instead.

void PfWidget::setViewAll ( ) [slot]

View entire scene.

This function positions the camera to view the entire scene.
