#include <GLItems.h>

Inheritance diagram for GLItem:

GLUItem GLUEdgeWidget GLUNodeWidget List of all members.

Detailed Description

a generic gl object, just a base class

Definition at line 30 of file GLItems.h.

compile to a display list?

bool compiles () const
void setCompile (bool yes)

Public Member Functions

virtual ~GLItem ()
void drawGL ()
 drawGL handles some display list stuff for you, you have to call "setUP()" if the object changes and needs to have the disp list re-compiled.

void setUp (bool yes=true)
 object needs update? something changed, for display lists mostly

void initNames (unsigned int name1, unsigned int name2)
 gl name for picking + push "this pointer" as second name be sure to call "popNames when you are through" ...

void pushName (unsigned int name)
 push a name on the pick stack, keeps track of how many you pushed so that when you call popNames() they all come off

void popNames ()
 pop all names pushed on stack


Protected Member Functions

virtual void drawGLDef ()=0
 GLItem (bool compile=true)
 GLItem (const GLItem &gli)

Protected Attributes

GLuint _listName
bool _compile
bool _update
int _numNames

void GLItem::drawGL (   ) 
 

drawGL handles some display list stuff for you, you have to call "setUP()" if the object changes and needs to have the disp list re-compiled.

drawGL() only calls "drawGLDef()" if the display list is being recompiled or you turn compilation off.
