<![CDATA[QPluginLoader]]>Hi Developer Network,

I'm working over plugin arquitecture aproach, but I have a question about plugin loader.
If I call QPluginLoader::unload(), the loader free reserved memory for loaded object? or have I call delete operator?.

@QObject *pluginInstance = m_loader.instance();
if (!pluginInstance)
continue;
PluginFactory *pluginFactory = qobject_cast<PluginFactory *>(pluginInstance);

if (!pluginFactory)
continue;

Plugin *plugin = pluginFactory->plugin(); // PluginFactory::plugin() { return new Plugin(); }

if (!plugin)
continue;

m_loader.unload();

// delete plugin;@

Thank you for your help ;)

Ok DerManu,

Thank you for your explanation (about QPluginLoader). I'll check my memory management.

BR,

//EDIT: And since you create it via "new Plugin();" and not "new Plugin(this);", it isn't a child of the factory and you'll need to delete it yourself.
