This class creates and provides connection with X server. Raises exception if can not connect to X server. On Windows and Mac OS X (in case when Cocoa used) platforms this class do nothing. WARRNING: Do not close display connection manualy! More...

Public Member Functions | |
Aspect_DisplayConnection () | |
Default constructor. Creates connection with display name taken from "DISPLAY" environment variable. More... | |
~Aspect_DisplayConnection () | |
Destructor. Close opened connection. More... | |
Aspect_DisplayConnection (const TCollection_AsciiString &theDisplayName) | |
Constructor. Creates connection with display specified in theDisplayName. Display name should be in format "hostname:number" or "hostname:number.screen_number", where: hostname - Specifies the name of the host machine on which the display is physically attached. number - Specifies the number of the display server on that host machine. screen_number - Specifies the screen to be used on that server. Optional variable. More... | |

Public Member Functions inherited from Standard_Transient | |
Standard_Transient () | |
Empty constructor. More... | |
Standard_Transient (const Standard_Transient &) | |
Copy constructor – does nothing. More... | |
Standard_Transient & | operator= (const Standard_Transient &) |
Assignment operator, needed to avoid copying reference counter. More... | |
virtual | ~Standard_Transient () |
Destructor must be virtual. More... | |
virtual void | Delete () const |
Memory deallocator for transient classes. More... | |
virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
Returns a type descriptor about this object. More... | |
Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
Returns a true value if this is an instance of Type. More... | |
Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
Returns a true value if this is an instance of TypeName. More... | |
Standard_Boolean | IsKind (const opencascade::handle< Standard_Type > &theType) const |
Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
Standard_Boolean | IsKind (const Standard_CString theTypeName) const |
Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. More... | |
Standard_Transient * | This () const |
Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. More... | |
Standard_Integer | GetRefCount () const |
Get the reference counter of this object. More... | |
void | IncrementRefCounter () const |
Increments the reference counter of this object. More... | |
Standard_Integer | DecrementRefCounter () const |
Decrements the reference counter of this object; returns the decremented value. More... | |
Additional Inherited Members | |
Public Types inherited from Standard_Transient | |
typedef void | base_type |
Returns a type descriptor about this object. More... | |
Static Public Member Functions inherited from Standard_Transient | |
static const char * | get_type_name () |
Returns a type descriptor about this object. More... | |
static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
Returns type descriptor of Standard_Transient class. More... | |
