@interface ICoreListener
|
|
@brief The ICoreListener is an interface for providing a hook for plugins to veto on close event emitted from
|
|
the core plugin.
|
|
@details You implement this interface if you want to prevent the closing of the whole application.
|
|
If the application window requests a close, then first ICoreListener::closeMainWindow() is called
|
|
(in arbitrary order) on all registered objects implementing this interface.
|
|
If one if these calls returns false, the process is aborted and the event is ignored. If all calls return
|
|
true, the corresponding signal is emitted and the event is accepted/performed.
|
|
|
|
You need to add your implementing object to the plugin managers objects:
|
|
PluginManager->addObject(yourImplementingObject);
|
|
Don't forget to remove the object again at deconstruction (e.g. in the destructor of
|
|
your plugin)
