This is a very basic question, but I’m inexperienced and can’t work out what to search for.
I have a instance of a class that does most of the work in my application. It is owned by my MainContentComponent, but (so far) does not itself inherit from any juce classes.
It needs to send a simple message (just a ping really) to the MainContentComponent when an event occurs that is not user generated, so the MainContentComponent can update the gui. rather like a button and listener setup.
What is the simplest lightest way to do this?
