I’m not sure if this is a problem in the way I am exporting my projects with the Introjucer or not but the following lines don’t get into juce_Events.h on windows when using the Introjucer to create a project. I tried building a few sample project with the user and to use sendNotfication I had to manually add these lines.
#ifndef JUCE_NOTIFICATIONTYPE_JUCEHEADER
#include “messages/juce_NotificationType.h”
#endif
