\property QPluginLoader::fileName
\brief the file name of the plugin
- To be loadable, the file's suffix must be a valid suffix for a
- loadable library in accordance with the platform, e.g. \c .so on
- Unix, \c .dylib on Mac OS X, and \c .dll on Windows. The suffix
- can be verified with QLibrary::isLibrary().
+ We recommend omitting the file's suffix in the file name, since
+ QPluginLoader will automatically look for the file with the appropriate
+ suffix (see QLibrary::isLibrary()).
+
+ When loading the plugin, QPluginLoader searches in the current directory and
+ in all plugin locations specified by QCoreApplication::libraryPaths(),
+ unless the file name has an absolute path. After loading the plugin
+ successfully, fileName() returns the fully-qualified file name of
+ the plugin, including the full path to the plugin if one was given
+ in the constructor or passed to setFileName().
If the file name does not exist, it will not be set. This property
will then contain an empty string.
