ofxUI addon save value from guiEvent()

Hi there, I am using the text field widget from the ofxUI addon. What I would like to do is to grab the string cityOutput variable form the guiEvent() method and reuse it in draw(). I can't seem to figure out how to do it because void guiEvent() does not return anything, and if i change it to string guiEvent() and return the string, ofAddListener() won't take it as an argument.

void ofApp::guiEvent(ofxUIEventArgs &e)
{
    string name = e.getName();
    if(name == "city"){
        ofxUITextInput *ti = (ofxUITextInput *) e.widget;
        string cityOutput = ti->getTextString();
        cout << cityOutput << endl;
        
        
        if(ti->getInputTriggerType() == OFX_UI_TEXTINPUT_ON_ENTER)
        {
            cout << "ON ENTER: ";
            
        }
        else if(ti->getInputTriggerType() == OFX_UI_TEXTINPUT_ON_FOCUS)
        {
            cout << "ON FOCUS: ";
        }
        else if(ti->getInputTriggerType() == OFX_UI_TEXTINPUT_ON_UNFOCUS)
        {
            cout << "ON BLUR: ";
        }
        
    }
