Public Member Functions

 Traits (DisplaySettings *ds=0)
bool getContextVersion (unsigned int &major, unsigned int &minor) const
 return true if glContextVersion is set in the form major.minor, and assign the appropriate major and minor values to the associated parameters.
Public Member Functions inherited from osg::Referenced
 Referenced ()
 Referenced (bool threadSafeRefUnref)
 Deprecated, Referenced is now always uses thread safe ref/unref, use default Referenced() constructor instead.
 Referenced (const Referenced &)
Referencedoperator= (const Referenced &)
virtual void setThreadSafeRefUnref (bool)
 Deprecated, Referenced is always theadsafe so there method now has no effect and does not need to be called.
bool getThreadSafeRefUnref () const
 Get whether a mutex is used to ensure ref() and unref() are thread safe.
OpenThreads::Mutex * getRefMutex () const
 Get the mutex used to ensure thread safety of ref()/unref().
int ref () const
 Increment the reference count by one, indicating that this object has another pointer which is referencing it.
int unref () const
 Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
int unref_nodelete () const
 Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
int referenceCount () const
 Return the number of pointers currently referencing this object.
ObserverSetgetObserverSet () const
 Get the ObserverSet if one is attached, otherwise return NULL.
ObserverSetgetOrCreateObserverSet () const
 Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet.
void addObserver (Observer *observer) const
 Add a Observer that is observing this object, notify the Observer when this object gets deleted.
void removeObserver (Observer *observer) const
 Remove Observer that is observing this object.

 ScreenIdentifier ()
 ScreenIdentifier (int in_screenNum)
 ScreenIdentifier (const std::string &in_hostName, int in_displayNum, int in_screenNum)
std::string displayName () const
 Return the display name in the form hostName::displayNum:screenNum.
void readDISPLAY ()
 Read the DISPLAY environmental variable, and set the ScreenIdentifier accordingly.
void setScreenIdentifier (const std::string &displayName)
 Set the screenIndentifier from the displayName string.
void setUndefinedScreenDetailsToDefaultScreen ()
 Set any undefined displayNum or screenNum values (i.e.
