wxBitmapDataObject is a specialization of wxDataObject for bitmap data. It can be used without change to paste data into the wxClipboard or a wxDropSource. A user may wish to derive a new class from this class for providing a bitmap on-demand in order to minimize memory consumption when offering data in several formats, such as a bitmap and GIF.
wxPython での注意点: If you wish to create a derived wxBitmapDataObject class in wxPython you should derive the class from wxPyBitmapDataObject in order to get Python-aware capabilities for the various virtual methods.
Virtual functions to override
This class may be used as is, but GetBitmap may be overridden to increase efficiency.

Constructor, optionally passing a bitmap (otherwise use SetBitmap later).
virtual wxBitmap GetBitmap(void) const
Returns the bitmap associated with the data object. You may wish to override this method when offering data on-demand, but this is not required by wxWidgets' internals. Use this method to get data in bitmap form from the wxClipboard.
Sets the bitmap associated with the data object. This method is called when the data object receives data. Usually there will be no reason to override this function.ymasuda 平成17年11月19日
