Sets the \a filters used in the file dialog.
+ Note that the filter \b{*.*} is not portable, because the historical
+ assumption that the file extension determines the file type is not
+ consistent on every operating system. It is possible to have a file with no
+ dot in its name (for example, \c Makefile). In a native Windows file
+ dialog, \b{*.*} will match such files, while in other types of file dialogs
+ it may not. So it is better to use \b{*} if you mean to select any file.

+ \l setMimeTypeFilters() has the advantage of providing all possible name
+ filters for each file type. For example, JPEG images have three possible
+ extensions; if your application can open such files, selecting the
+ \c image/jpeg mime type as a filter will allow you to open all of them.
