Are the vaadin components responsive by default?

Question

here I am currently working on a project developed by Vaadin Version 8. I use the Valo theme to add style. But I see that there is the setResponsive method which belongs to each component. I would like to know if the components are responsive by default or I have to set them to true Thanks

Answer 1

setResponsive method is coming from the AbstractComponent class. So any component extending this class has the method. Functionality is implemented as an AbstractExtension (Responsive).

Before setting Responsiveness it's checked if a component has an extension already. Extensions are saved inside the extensions field of the AbstractClientConnector class, which is empty by default. (AbstractComponent also extends AbstractClientConnector, so each components extends it as well). None of the components seems to add any default extensions.

Therefore, by default responsiveness is not enabled.
