RAP 3.1 M4 - New and Noteworthy

Transformation Support for Canvas

GC now implements the setTransform method.

Transform transform = new Transform( display );
gc.setTransform( transform );
gc.setBackground( display.getSystemColor( SWT.COLOR_BLACK ) );
gc.fillRectangle( 0, 0, 100, 50 );

transform.rotate( 10 );
gc.setTransform( transform );
gc.setBackground( display.getSystemColor( SWT.COLOR_RED ) );
gc.fillRectangle( 0, 0, 100, 50 );

transform.rotate( 10 );
gc.setTransform( transform );
gc.setBackground( display.getSystemColor( SWT.COLOR_YELLOW ) );
gc.fillRectangle( 0, 0, 100, 50 );

Column Span Support for Nebula Grid

GridItem now implements the setColumnSpan method. The Grid itself has been given a more spreadsheet-like default look to better work with this new feature. It is now also separately themeable (previously shared the a theme with Tree).

Selection Theming update for all Table/List-based Widgets

Tree, Table, Grid, List, Combo, CCombo and DropDown have a new default theming for selected items. Instead of a dark-blue gradient a solid, semi-transparent light blue is used. This preserves the color of the text elements (they are now longer set to white) and allows elements like cell backgrounds that are normally hidden beneath the selection effect to shine through. It also works better with the new Nebula Grid look. The business theme remains unchanged.
