The \a Identifier must + be unique. For example: + + \snippet examples/tools/plugandpaint/interfaces.h 3 + + This macro is normally used right after the class definition for + \a ClassName, in a header file. See the + \l{tools/plugandpaint}{Plug & Paint} example for details. + + If you want to use Q_DECLARE_INTERFACE with interface classes + declared in a namespace then you have to make sure the Q_DECLARE_INTERFACE + is not inside a namespace though. For example: + \snippet doc/src/snippets/code/doc_src_qplugin.qdoc 0 + + \sa Q_INTERFACES(), Q_EXPORT_PLUGIN2(), {How to Create Qt Plugins} +*/ + +/*! + \macro Q_EXPORT_PLUGIN(ClassName) + \relates <QtPlugin> + \obsolete + + Use Q_EXPORT_PLUGIN2() instead.

The value of \a PluginName should correspond to the + \l{qmake Variable Reference#TARGET}{TARGET} specified in the plugin's + project file. + + There should be exactly one occurrence of this macro in the source code + for a Qt plugin, and it should be used where the implementation is written + rather than in a header file. + + Example: + + \snippet doc/src/snippets/code/doc_src_qplugin.qdoc 1 + + See the \l{tools/plugandpaint}{Plug & Paint} example for details. + + \sa Q_DECLARE_INTERFACE(), {How to Create Qt Plugins} +*/ + +/*! + \macro Q_IMPORT_PLUGIN(PluginName) + \relates <QtPlugin> + + This macro imports the plugin named \a PluginName, corresponding + to the \l{qmake Variable Reference#TARGET}{TARGET} specified in the + plugin's project file. + + Inserting this macro into your application's source code will allow + you to make use of a static plugin. + + Example: + + \snippet doc/src/snippets/code/doc_src_qplugin.qdoc 2 + + Static plugins must also be included by the linker when your + application is built. For Qt's predefined plugins, + you can use the \c QTPLUGIN to add + the required plugins to your build.
