RAP 3.0 M6 - New and Noteworthy

Here's a list of the most noteworthy things in the RAP 3.0 M6 milestone build which is available for download since March 27, 2015.

FileDialog migrated to RAP Core

The file dialog and file upload components have been moved from the RAP Incubator to the RAP repository. FileDialog supports not only single and multi file upload with a clean user interface, but since recently also file drag and drop.

FileDialog is now of RAP

Badge support for Push Button and ToolItem

In the second milestone of RAP 3.0 we added badge support for TabItem. Now, this has been extended to Button and ToolItem, both with style SWT.PUSH.

Badges on Button

To set a badge, use:

button.setData( RWT.BADGE, "12" );

Minimum Firefox, Chrome, Opera and Safari version raised

In RAP 3.0, the web client will support the following web browsers/rendering engines:

  • Internet Explorer 9 and later
  • Google Chrome 29 and later
  • Firefox 23 and later
  • Safari 6 and later
  • Opera 15 and later
  • iOs 6 and later (Safari)
  • Android 4 and later (stock browser (limited) and Chrome)

In some older browsers RAP may continue to work, but without additional modern HTML5/CSS3 features.


This list shows all bugs that have been fixed for this milestone build.
