Open the .jucer project in Projucer, check that the modules paths are pointing to existing folders, then re-save the project.
I hope this helps.
why nothing comes out when I click that button
tutorial demo project
Did you compile the example with ListenersAndBroadcastersTutorial_04.h file?
Main.cpp
#include <JuceHeader.h>
#include "ListenersAndBroadcastersTutorial_04.h"
Notice that in general:
- You should open a new thread for a new question.
- Community will appreciate less pictures and more explanations.
How in visual studio 2019? I thought just click local windows debugger is fine
You just have to edit the Main.cpp file with your favourite text editor to replace that line:
#include "ListenersAndBroadcastersTutorial_01.h"
with that line:
#include "ListenersAndBroadcastersTutorial_04.h"
.
.
.
But IMHO you should learn a bit the basis of C++ before to try to learn JUCE.
You would lose less time in trial and error series.
And as a bonus it should be more friendly for people that spend time to help you.
wait, why 04? another .h is 01
The tutorials provide various headers (suffixed with a number) at different stages of the project.
You must include the good one at compilation to see the feature.
