Class WBootstrap2Theme

public class WBootstrap2Theme extends WTheme
Theme based on the Twitter Bootstrap 2 CSS framework.

This theme implements support for building a JWt web application that uses Twitter Bootstrap as a theme for its (layout and) styling. The theme comes with CSS from Bootstrap version 2.2.2. Only the CSS components of twitter bootstrap are used, but not the JavaScript (i.e. the functional parts), since the functionality is already built-in to the widgets from the library.

Using this theme, various widgets provided by the library are rendered using markup that is compatible with Twitter Bootstrap. The bootstrap theme is also extended with a proper (compatible) styling of widgets for which bootstrap does not provide styling (table views, tree views, sliders, etc...).

By default, the theme will use CSS resources that are shipped together with the JWt distribution, but since the Twitter Bootstrap CSS API is a popular API for custom themes, you can easily replace the CSS with custom-built CSS (by reimplementing getStyleSheets()).

Although this theme facilitates the use of Twitter Bootstrap with JWt, it is still important to understand how Bootstrap expects markup to be, especially related to layout using its grid system, for which we refer to the official bootstrap documentation, see
