/*
|
||||
* wxVariantData stores the actual data in a wxVariant object,
|
||||
* to allow it to store any type of data.
|
||||
* Derive from this to provide custom data handling.
|
||||
*
|
||||
* NB: To prevent addition of extra vtbl pointer to wxVariantData,
|
||||
* we don't multiple-inherit from wxObjectRefData. Instead,
|
||||
* we simply replicate the wxObject ref-counting scheme.
|
||||
*
|
||||
* NB: When you construct a wxVariantData, it will have refcount
|
||||
* of one. Refcount will not be further increased when
|
||||
* it is passed to wxVariant. This simulates old common
|
||||
* scenario where wxVariant took ownership of wxVariantData
|
||||
* passed to it.
|
||||
* If you create wxVariantData for other reasons than passing
|
||||
* it to wxVariant, technically you are not required to call
|
||||
* DecRef() before deleting it.
|
||||
*
|
||||
* TODO: in order to replace wxPropertyValue, we would need
|
||||
* to consider adding constructors that take pointers to C++ variables,
|
||||
* or removing that functionality from the wxProperty library.
|
||||
* Essentially wxPropertyValue takes on some of the wxValidator functionality
|
||||
* by storing pointers and not just actual values, allowing update of C++ data
|
||||
* to be handled automatically. Perhaps there's another way of doing this without
|
||||
* overloading wxVariant with unnecessary functionality.
