void Q_CLEANUP_RESOURCE ( name )

Unloads the resources specified by the .qrc file with the base name name .

Normally, Qt resources are unloaded automatically when the application terminates, but if the resources are located in a plugin that is being unloaded, call Q_CLEANUP_RESOURCE() to force removal of your resources.

注意： This macro cannot be used in a namespace. Please see the Q_INIT_RESOURCE documentation for a workaround.

范例：

Q_CLEANUP_RESOURCE(myapp);

void Q_INIT_RESOURCE ( name )

Initializes the resources specified by the .qrc file with the specified base name . Normally, when resources are built as part of the application, the resources are loaded automatically at startup. The Q_INIT_RESOURCE() macro is necessary on some platforms for resources stored in a static library.

For example, if your application's resources are listed in a file called myapp.qrc , you can ensure that the resources are initialized at startup by adding this line to your main() 函数：

Q_INIT_RESOURCE(myapp);
					

If the file name contains characters that cannot be part of a valid C++ function name (such as '-'), they have to be replaced by the underscore character ('_').

注意： This macro cannot be used in a namespace. It should be called from main(). If that is not possible, the following workaround can be used to init the resource myapp from the function MyNamespace::myFunction :

inline void initMyResource() { Q_INIT_RESOURCE(myapp); }
namespace MyNamespace
{
    ...
    void myFunction()
    {
        initMyResource();
    }
}
