Package wx :: Class PyDataObjectSimple |

wx.PyDataObjectSimple is a version of wx.DataObjectSimple
that is
Python-aware and knows how to reflect calls to its C++ virtual methods
to methods in the Python derived class. You should derive from this
class and overload GetDataSize
, GetDataHere
and SetData
when you
need to create your own simple single-format type of wx.DataObject
.
Here is a simple example:
class MyDataObject(wx.PyDataObjectSimple): def __init__(self): wx.PyDataObjectSimple.__init__( self, wx.CustomDataFormat('MyDOFormat')) self.data = '' def GetDataSize(self): return len(self.data) def GetDataHere(self): return self.data # returns a string def SetData(self, data): self.data = data return True
Note that there is already a wx.CustomDataObject
class that behaves
very similarly to this example. The value of creating your own
derived class like this is to be able to do additional things when the
data is requested or given via the clipboard or drag and drop
operation, such as generate the data value or decode it into needed
data structures.
