Backround of TableViewer is always blue/grey. [message #511961]

This only happens when i'm using e4. Using Eclipse 3.6 the backround is white. I checked the color of the table at runtime and it is white. The TreeViewer works fine. I have no idea where this strange backround is coming from.

Here is a sample:

Please provide a) the code to reproduce the problem, b) the e4 SDK build you were using, and c) information about your setup such as OS, JVM version, etc, etc.

Sorry, i forgot the important part.

The code:

// Table
table = new TableViewer( group2, SWT.H_SCROLL | SWT.V_SCROLL | SWT.MULTI | SWT.BORDER );
gd = new GridData( GridData.FILL_BOTH );
gd.minimumWidth = 300;
table.getControl().setLayoutData( gd );
table.getTable().setLinesVisible( true );
table.getTable().setHeaderVisible( true );
TableViewerColumn columnName = new TableViewerColumn(table, SWT.NONE);
columnName.getColumn().setText( "Spaltenbezeichnung" );
columnName.getColumn().setWidth( 200 );
columnName.getColumn().setResizable(true);
table.setContentProvider( new TableContentProvider() );
table.setLabelProvider( new TableLabelProvider() );
table.setInput( columnsTemp );

// Content provider
class TableContentProvider implements IStructuredContentProvider {

        @Override
        public Object[] getElements( Object inputElement ) {
            return columnsTemp.toArray();
        }

        @Override
        public void dispose() {

        }

        @Override
        public void inputChanged( Viewer viewer, Object oldInput, Object newInput ) {

        }

    }


// Label provider
class TableLabelProvider implements ITableLabelProvider {

        @Override
        public Image getColumnImage( Object element, int columnIndex ) {
            return null;
        }

        @Override
        public String getColumnText( Object element, int columnIndex ) {

            return ((FeatureAttributeConfigColumn) element).getLabel();
        }

        @Override
        public void addListener( ILabelProviderListener listener ) {

        }

        @Override
        public void dispose() {

        }

        @Override
        public boolean isLabelProperty( Object element, String property ) {
            return true;
        }

        @Override
        public void removeListener( ILabelProviderListener listener ) {

        }

   
 }

I'm using:

- Eclipse 3.6M4 with e4 1.0M3 as target platform

- Java 6 Update 17

- Windows XP Service Pack 3

I have SP2 with IBM JVMs and could not reproduce the problem. Please try reproducing with the code below and/or change the code below sufficiently to reproduce the problem.

Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout(1, true));

TableViewer table = new TableViewer(shell, SWT.H_SCROLL | SWT.V_SCROLL
		| SWT.MULTI | SWT.BORDER);
GridData gd = new GridData(GridData.FILL_BOTH);
gd.minimumWidth = 300;
table.getControl().setLayoutData(gd);
table.getTable().setLinesVisible(true);
table.getTable().setHeaderVisible(true);
TableViewerColumn columnName = new TableViewerColumn(table, SWT.NONE);
columnName.getColumn().setText("Spaltenbezeichnung");
columnName.getColumn().setWidth(200);
columnName.getColumn().setResizable(true);
table.setContentProvider(ArrayContentProvider.getInstance());
table.setLabelProvider(new LabelProvider());
table.setInput(new String[] { "a", "b" });

shell.pack();
shell.open();
while (!shell.isDisposed()) {
	if (!display.readAndDispatch())
		display.sleep();
}
display.dispose();

I found out whats wrong. It was a entry in the css-file:

Table {
	background-color: #e8e8e8 #cccccc 60%;
	color: black;
	font: Verdana 8px;
}

How stupid is that? A leftover from trying out e4 a while ago.

Thanks for your help.
