How to call the override pause method dynamically from Libgdx?

Question

I create a Libgdx game and I want to know if it is possible to call the override pause method lifecycle with Libgdx?

Here is my pause method lifecycle in my class:

public class MyGdxGame extends ApplicationAdapter {
    @Override
    public void pause() {
        super.pause();
        chrono.pause();
        //Display a pause menu
    }
}

And I want to call the lifecycle method when I click on the pause image:

    imagePause = new Image(new Texture(Gdx.files.internal("pause.png")));
    imagePause.setSize(pauseSize, pauseSize);
    imagePause.setPosition(width - pauseSize, height - pauseSize);
    imagePause.addListener(new ClickListener() {
        @Override
        public void clicked(InputEvent event, float x, float y) {
            //Something like this? :
            Gdx.app.pause(); //Doesn't exist

            //I don't want to call manually the pause method like this       
            //because it doesn't pause Libgdx lifecycle ...
            pause();
        }
    });
    stage.addActor(imagePause);

Any idea?

What exactly do you want to happen after pressing the pause button? You say you want to pause the libgdx lifecycle. How are you planning to resume it afterwards? — noone, Jul 28 '15 at 16:27
When I press the pause button, I want to pause everything in Libgdx and I want to display a pause menu with a play button. I am planning to resume the lifecycle when the user close the pause menu by clicking on the play button. — Wingjam, Jul 28 '15 at 17:06
You cannot display anything, when the libgdx lifecycle is completely stopped. Just set a `paused` variable, check that in your `render()` method and skip all gameplay stuff in case it's paused. Also display your pause menu. — noone, Jul 28 '15 at 17:20
Yeah, I think you're getting thrown by the word pause being used as the name of a lifecycle event. You don't want to mess with that. Create your own type of pause that changes what's happening in the render loop, like @noone said. — Tenfour04, Jul 28 '15 at 17:22

If your goal is to stop the render:

To stop the render:

Gdx.graphics.setContinuousRendering(false);

To put it back on:

Gdx.graphics.setContinuousRendering(true);

To trigger render when the rendering is stop:

Gdx.graphics.requestRendering();

Hope it will help you.
