Ok, I think I get it. Internal DnD will use the first specified mime type.
That still raises the question of the purpose of the mimeType() method. The
documentation implies that mimeType() specifies the formats supplied when used
as a drop source. How do you control the accepted types when used as a drop
target? Or is mimeType() used for both drop source and target?
i'm going to answer your questions by not answering them :)
whenever i encounter situations where i'm going to reimplement virtual
methods, i will usually take a look at the qt source at some point. i
will look at the details of the default implementation, and also how the
method is used internally by other methods. if the method is part of an
abstract class, i might also look at how qt has reimplemented it in its
own subclasses (for example, by comparing qtreeview with qtreewidget).
why waste time designing everything from scratch when the kindly trolls
have already done most of it for me?
the qt documentation is good, but there is no substitute for reading the
source when you really need to know how things work.
