wx.CustomDataObject¶wx.CustomDataObject is a specialization of wx.DataObjectSimple for some application-specific data in arbitrary (either custom or one of the standard ones).
The only restriction is that it is supposed that this data can be copied bitwise (i.e. with memcpy() ), so it would be a bad idea to make it contain a C++ object (though C struct is fine).
By default, wx.CustomDataObject stores the data inside in a buffer. To put the data into the buffer you may use either SetData or TakeData depending on whether you want the object to make a copy of data or not.
This class may be used as is, but if you don’t want store the data inside the object but provide it on demand instead, you should override GetSize, GetData and SetData (or may be only the first two or only the last one if you only allow reading/writing the data).
