Control the module

notifyEvent("setIdle", j);

Get messages from the module

Depending of the selected streaming method you receive the cam image as ofTexture or ofPixels. A photo arrives at the address photo, other messages represent the current live view.

void Presenter::proceedModuleEvent(ModuleEvent& e) {
		
		// update the cam image 
		if (e.type == ModuleEvent::MODULE_EVENT_TEXTURE) {
		  camTexture = e.texture;
		}else if (e.type == ModuleEvent::MODULE_EVENT_PIXELS) {
			camPic.setFromPixels(*e.pixels);
		}
    }
