pfSimpleDrawAction(3pf) OpenGL Performer 3.2.2 libpfx C++ Reference Pages
NAMEpfSimpleDrawAction - Simplest draw action which clears channel and allows
user to toggle stats and set draw style
FUNCTION SPECIFICATION
#include <Performer/pfx/pfSimpleDrawAction.h>
pfSimpleDrawAction::pfSimpleDrawAction();
static pfType* pfSimpleDrawAction::getClassType(void);
virtual void pfSimpleDrawAction::preDraw(pfChannel *, pfViewer *);
virtual void pfSimpleDrawAction::postDraw(pfChannel *, pfViewer *);
void pfSimpleDrawAction::setDrawStyle(int drawStyle);
int pfSimpleDrawAction::getDrawStyle();
void pfSimpleDrawAction::setDrawStatsStatus(int onOrOff);
int pfSimpleDrawAction::getDrawStatsStatus();
PARENT CLASS FUNCTIONS
The OpenGL Performer class pfSimpleDrawAction is derived from the parent
class pfDrawAction, so each of these member functions of class
pfDrawAction are also directly usable with objects of class
pfSimpleDrawAction. This is also true for ancestor classes of class
pfDrawAction.
virtual void pfDrawAction::preDraw(pfChannel *, pfViewer *);
virtual void pfDrawAction::postDraw(pfChannel *, pfViewer *);
Since the class pfDrawAction is itself derived from the parent class
pfObject, objects of class pfSimpleDrawAction can also be used with these
functions designed for objects of class pfObject.
void* pfObject::operator new(size_t);
void* pfObject::operator new(size_t, pfFluxMemory *fmem);
void pfObject::setUserData(void *data);
void pfObject::setUserData(int slot, void *data);
void* pfObject::getUserData(pfObject *obj);
void* pfObject::getUserData(pfObject *obj, int slot);
int pfObject::getNumUserData();
Since the class pfObject is itself derived from the parent class
pfMemory, objects of class pfSimpleDrawAction can also be used with these
functions designed for objects of class pfMemory.

DESCRIPTION
new pfSimpleDrawAction creates and returns a handle to a
pfSimpleDrawAction. Like other pfDrawActions, pfSimpleDrawActions are
always allocated from shared memory and can be deleted by the calling
pfDelete().
This particular draw action allows the user to turn on and off stats
display and set the draw style. By default, the draw style is set to
PFUSTYLE_FILLED and the stats are off. The draw style may be changed via
pfSimpleDrawAction::setDrawStyle() and retrieved via
pfSimpleDrawAction::getDrawStyle().
The stats display may set turned on or off via
pfSimpleDrawAction::setDrawStatsStatus(int onOrOff) and the current value
may be retrieved via pfSimpleDrawAction::getDrawStatsStatus().
NOTES
There is a sample of how to implement draw actions in the
/usr/share/Perfomer/src/pguide/libpfx/ directory.
The libpfx source code, object code and documentation are provided as
unsupported software. Routines are subject to change in future releases.
