The decoration element is optional, so we have two or three DOM elements per widget. This is a bit more than in 0.7 but we can compensate that by using less widgets in general: <ul><li> If you wanted to have advanced styling like buttons with borders composed of sprites, you had to create separate image widgets and insert them into the button's layout. Now you can just create a decoration renderer, which comes without the overhead of a complete widget and can use less DOM elements </li> <li>The layout managers have improved. In places, where we formerly had to use a combination of box layouts, each a separate widget instance, we can now use for example a single grid layout</li> <li>Spacer widgets, which are for example used in toolbars, don't have a DOM element. They just allocate the space an equally configured widget would take in the layout.</li> </ul> As a conclusion: Yes, new widgets do have more DOM elements but we expect that the overall number of DOM elements will be about the same. On the other hand we expect that the number of widget instances will be lower. Fabian Hello Jochen,

Thanks for the feedback. The decoration element is optional, so we have two or three DOM elements per widget. This is a bit more than in 0.7 but we can compensate that by using less widgets in general:

  • If you wanted to have advanced styling like buttons with borders composed of sprites, you had to create separate image widgets and insert them into the button’s layout. Now you can just create a decoration renderer, which comes without the overhead of a complete widget and can use less DOM elements
  • The layout managers have improved. In places, where we formerly had to use a combination of box layouts, each a separate widget instance, we can now use for example a single grid layout
  • Spacer widgets, which are for example used in toolbars, don’t have a DOM element. They just allocate the space an equally configured widget would take in the layout.

As a conclusion: Yes, new widgets do have more DOM elements but we expect that the overall number of DOM elements will be about the same. On the other hand we expect that the number of widget instances will be lower.

The direction of separating concerns for widgets and layouts looks very good (and familiar ..). Just one question: Does the new structure mean that there will be three divs for every widget, one for widget, decoration and content? How does this compare to 0.7 in terms of overall DOM elements? Sorry for not using the mailing list ... Jochen Interesting slides! The direction of separating concerns for widgets and layouts looks very good (and familiar ..).
