Intellij plugin development, how to prevent an action from occuring, like closing a tab - intellij-idea

Question

Is this possible?
I need to subscribe to the event somehow and possibly return false or similar, i am guessing. I have no idea how though.
What event is that?
Where do I register it?
Anyone?
EDIT:
I have tried this:
import com.intellij.openapi.components.ApplicationComponent;
import com.intellij.openapi.editor.impl.EditorComponentImpl;
import org.jetbrains.annotations.NotNull;
import java.awt.*;
import java.awt.event.AWTEventListener;
import java.awt.event.KeyEvent;
public class MyPlugin implements ApplicationComponent {
static {
/*MessageBus bus = ApplicationManager.getApplication().get
MessageBusConnection connection = bus.connect();
connection.subscribe(AppTopics.FILE_DOCUMENT_SYNC,
new FileDocumentManagerAdapter() {
#Override
public void beforeDocumentSaving(Document document) {
// create your custom logic here
}
});*/
}
private final AWTEventListener listener;
public MyPlugin() {
System.out.println("111111111111111111");
listener = new AWTEventListener() {
#Override
public void eventDispatched(AWTEvent event) {
if ( event instanceof KeyEvent ) {
KeyEvent kv = (KeyEvent) event;
Component component = kv.getComponent();
if ( component instanceof EditorComponentImpl) {
EditorComponentImpl cp = (EditorComponentImpl) component;
}
System.out.println("3333333" + component.getClass());
}
System.out.println("aaaaaaa" + event.getClass());
}
};
}
#Override
public void initComponent() {
System.out.println("bbbbbbbbbbbbbbbbbbbbbbbbbbb");
Toolkit.getDefaultToolkit().addAWTEventListener(listener, AWTEvent.KEY_EVENT_MASK);
}
#Override
public void disposeComponent() {
Toolkit.getDefaultToolkit().removeAWTEventListener(listener);
}
#NotNull
#Override
public String getComponentName() {
return "temp";
}
}
But it does not work. I get events but the wrong kind.

Two plugins were developed in the end to accomplish this:
