Implement (or reimplement) class `wxMetafileDataObject` (Issue #25861)
Luca Allulli
lallulli created an issue (wxWidgets/wxWidgets#25861)In order to support clipboard and drag-and-drop operations involving Windows Metafiles alongside other formats (bitmaps, text, etc.), it would be very useful to have a wxMetafileDataObject class.
Such a class would make it possible to combine different formats within a single wxDataObjectComposite instance.
While searching for wxMetafileDataObject, I found references to it in Cross-Platform GUI Programming with wxWidgets by Julian Smart and Kevin Hock, which suggests that this class may have existed in earlier versions. If that’s the case, I’m not sure why it was removed.
Thank you for considering this!

vadz left a comment (wxWidgets/wxWidgets#25861)It hasn't been removed, but it's only available under Windows, in wx/msw/metafile.h header.
I don't think it makes sense to implement it for the other platforms as it's inherently Windows-specific, so I don't think we can/should do anything else here.

I would suggest adding this class to the official documentation: it doesn't appear either the class index or in the wxDataObject class hierarchy.
I'll try it in wxPython under Windows. It’s a bit odd that wx.MetafileDC is well documented and importable even on Linux, while wxMetafileDataObject seems somewhat hidden.

swt2c left a comment (wxWidgets/wxWidgets#25861)wxPython uses the wxWidgets interface headers (the files under the interface) directory in order to decide what classes and methods to make available to Python. This class isn't currently documented in the interface headers. @vadz should this class be documented?
