First, apologies for the long snippet.
I am having problem with understanding the behaviour of the setAlignment
method on the TableColumn. I can align text in the whole column of a table
quite nicely but am running into problems with I have an image on the
TableColumn as well. Basically it looks as though you can have one or the
other.
I have an example which by default sets the table alightment to SWT.RIGHT
for each column, and also has an image on the tableColumn (appears when you
click on the TableColumn) you will see depending on the order in which
setAlignment and setImage are called, you EITHER get an Image OR correctly
aligned text.
Is this a bug?
Thanks

{

if(column.getImage() == image)
{
// you can see an image this time
// but text is incorrectly aligned

Tried your example and it seems like a bug. Can you please enter a bug
report against Platform SWT for this? Thank you.
