MVP Jython framework, html panel and javascript code

Introduction
The dialog is displayed using default layout. The default layout is convenient at the beginning but later probably something more useful and better looking is necessary. So it is possible to replace default layout by means of GWT HTMLPanel widget. Just add to the dialog definition file containing dialog layout in shape of html page and new display is visible. Also custom Javascript code can be added to the page.
TabPanel is very useful way of displaying a lot of data on the screen without scrolls. TabPanel can be built by combining html, css and javascript code but GWT contains TabPanel widget.
HTMLPanel and JavaScript custom code

Sample application is available here (click at "Dialog HTML panel"). The html, css and JavaScript code was downloaded from this page. It does not make a lot of sense here, it is only a presentation how default layout can be enriched with html, css and custom Javascript code. More detailed description is available here.
Adding HTMLPanel definition impacts only presentation part. It does not involve any change in backing Jython code.
TabPanel

 

Sample application is available here (click at "Dialog tab panel"). The usage of the TabPanel is limited currently. For instance it is not possible to disperse buttons between different tab pages. More detailed description is available here.  
Problems

• Current implementation of HTMLPanel does not allow to use custom (internationalized) labels. It will be added later.
• Current implementation of TabPanel is limited. More flexible approach will be added later.
