can a default bool toggle be converted to button?

[moebiussurfing]

when adding a group parameter with parameters bools to a container/group, they are added by default as toggles.

How can we change this added toggles to buttons?

If adding the parameter bools one by one, there's no problem, as we can define them as buttons when adding them.

I tried to define the button parameter as void like this, then is added to the group parameter: ofParameter<void> BPM_Tap_Tempo_button; but the listeners who get the changed params do not detects the button widget change..

void ofApp::Changed_Params(ofAbstractParameter& e) 
{
    string wid = e.getName();
    ofLogNotice() << "Changed_Params '" << wid << "': " << e;

    if (wid == "MY_BUTTON")
    {
        ofLogNotice() << "changed MY_BUTTON '";
    }
}
