#include <wx/bitmap.h>
This class encapsulates a monochrome mask bitmap, where the masked area is black and the unmasked area is white.
When associated with a bitmap and drawn in a device context, the unmasked area of the bitmap will be drawn, and the masked area will not be drawn.

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). More... | |
wxObjectRefData * | GetRefData () const |
Returns the wxObject::m_refData pointer, i.e. the data referenced by this object. More... | |
bool | IsKindOf (const wxClassInfo *info) const |

void | Ref (const wxObject &clone) |
Makes this object refer to the data in clone. More... | |
void | SetRefData (wxObjectRefData *data) |
Sets the wxObject::m_refData pointer. More... | |
void | UnRef () |
Decrements the reference count in the associated data, and if it is zero, deletes the data. More... | |
