Hi,

There is a problem with the TableViewer.

I set the alignment of a TableColumn (column.setAlignment( SWT.CENTER );)

This works when put some text in the cell. (cell.setText( "someText" );)
But I put an image it the cell (cell.setImage( image );), the image will
always displayed left.

Is this a bug???

to reproduce see rap.demo #controls #Table-Tab

Roland

Roland,

if I'm not entirely mistaken, this behaviour is intended. The rule of
thumb is, if it works in SWT/RCP, it should work the same in RWT/RAP.
Hence, if you can prove that SWT behaves differently, then please file a
bugzilla.

Hi,

I have tested it in SWT and you're right. It shows the same behavior as
in RAP.

But the JavaDoc says:

Controls how text and *images* will be displayed in the receiver. The
argument should be one of LEFT, RIGHT or CENTER.

Strange.

It may be that SWT behaves differently on different platforms. However,
it could also be a bug in the documentation. If you want to be sure,
search for a bug or newsgroup entry in SWT.

I hit into the same problem too. Is there a way to align images also in the table cell? The image inside the table is always left-aligned.

Thanks.

No. This is not possible in the SWT table and it isn't in RAP. But maybe
the markup support added in 1.5 can be an alternative? When you enable
markup for a Table, you can put <img> tags into its text.
