Tobago 3

Until Tobago 2.0 the layout was computed on the server, to make advanced features available for comfortable web application.

With CSS3 and HTML5 it is possible these days, to make advanced layout managers implemented in the browser.

Bootstrap

The base theme that comes with Tobago changes from plain CSS to Twitters Bootstrap. So your applications have the advantage of modern HTML5 web applications with less coding.

New Layout Managers

• Segment Layout (uses the 12 columns layout from Bootstrap)
• Flex Layout (CSS3)
  You may replace the GridLayout from Tobago 2.0 with FlexLayout.
• Flow Layout
• The new layout managers have been written a bit more concised: Using as container instead of a facet.

tx library

• The tx library is no longer needed
• The label is integrated into the tc library.
• This results in a more intuitive API
• Rich variations of positioning the label with new attribute labelLayout

New tags

• <tc:section>
• <tc:header> & <tc:footer>
• <tc:figure>

Improved tags

• The <tc:in/> tag may be extended to an Input Group.
• A size attribute is added for
  • <tc:selectOneListbox>,
  • <tc:selectManyListbox>,
  • <tc:selectManyShuffle> and
  • <tc:treeListbox>.
• Only disabled="true" must be set to disable an image.
• <tc:sheet>
  • Constraints are no longer needed to set a multi-line header.
  • A width can be defined for columns which will influence the auto layout of the browser.

Internal Refactoring

• Using standard ajax mechanism.

Collapsible concept

There is a new collapsible concept for <tc:box>, <tc:section>, <tc:panel> and <tc:popup> where the collapse state can be switched via an <tc:operation>.
