wxGDIObject Class Reference
#include <wx/gdiobj.h>
Inheritance diagram for wxGDIObject:
Detailed Description
This class allows platforms to implement functionality to optimise GDI objects, such as wxPen, wxBrush and wxFont.
On Windows, the underling GDI objects are a scarce resource and are cleaned up when a usage count goes to zero. On some platforms this class may not have any special functionality.
Since the functionality of this class is platform-specific, it is not documented here in detail.
Library: wxCore
Category: Graphics Device Interface (GDI)
Public Member Functions | |
| wxGDIObject () | |
| Default constructor. | |
| Public Member Functions inherited from wxObject | |
| wxObject () | |
| Default ctor; initializes to NULL the internal reference data. | |
| wxObject (const wxObject &other) | |
| Copy ctor. | |
| virtual | ~wxObject () |
| Destructor. | |
| virtual wxClassInfo * | GetClassInfo () const |
| This virtual function is redefined for every class that requires run-time type information, when using the wxDECLARE_CLASS macro (or similar). | |
| wxObjectRefData * | GetRefData () const |
| Returns the wxObject::m_refData pointer, i.e. the data referenced by this object. | |
| bool | IsKindOf (const wxClassInfo *info) const |
| Determines whether this class is a subclass of (or the same class as) the given class. | |
| bool | IsSameAs (const wxObject &obj) const |
| Returns true if this object has the same data pointer as obj. | |
| void | Ref (const wxObject &clone) |
| Makes this object refer to the data in clone. | |
| void | SetRefData (wxObjectRefData *data) |
| Sets the wxObject::m_refData pointer. | |
| void | UnRef () |
| Decrements the reference count in the associated data, and if it is zero, deletes the data. | |
| void | UnShare () |
| This is the same of AllocExclusive() but this method is public. | |
| void | operator delete (void *buf) |
The delete operator is defined for debugging versions of the library only, when the identifier WXDEBUG is defined. | |
| void * | operator new (size_t size, const wxString &filename=NULL, int lineNum=0) |
The new operator is defined for debugging versions of the library only, when the identifier WXDEBUG is defined. | |
Additional Inherited Members | |
| Protected Member Functions inherited from wxObject | |
| void | AllocExclusive () |
| Ensure that this object's data is not shared with any other object. | |
| virtual wxObjectRefData * | CreateRefData () const |
| Creates a new instance of the wxObjectRefData-derived class specific to this object and returns it. | |
| virtual wxObjectRefData * | CloneRefData (const wxObjectRefData *data) const |
| Creates a new instance of the wxObjectRefData-derived class specific to this object and initializes it copying data. | |
| Protected Attributes inherited from wxObject | |
| wxObjectRefData * | m_refData |
| Pointer to an object which is the object's reference-counted data. | |
