Description Walter Mising name CLA 2008-12-09 09:43:21 EST 
When setting the Right alignment for a Tree Column in CheckboxTreeViewer ( Multiple Column ), the Header is right aligned but not the rows of that column.

Is this working in RCP?

Yes.

Can you provide a snippet to reproduce it?

    final Composite composite = new Composite ( parent, SWT.NONE ) ;

Hi Walter,
I've created a simple standalone SWT test case:
-------------
Tree tree = new Tree( shell, SWT.FULL_SELECTION | SWT.CHECK );
for( int i = 0; i < 3; i++ ) {
    TreeItem ti = new TreeItem( tree, SWT.NONE );
    ti.setText( "Item "+i );
    for( int j = 0; j < 3; j++ ) {
        TreeItem sti = new TreeItem( ti, SWT.NONE );
        sti.setText( "Subitem "+j+" of Item "+i );
    }
}
tree.setSize( 800,600 );
tree.setHeaderVisible( true );
TreeColumn col1 = new TreeColumn( tree, SWT.RIGHT );
col1.setText( "Col 1" );
col1.setWidth( 250 );
TreeColumn col2 = new TreeColumn( tree, SWT.LEFT );
col2.setText( "Col 2" );
col2.setWidth( 250 );
-----------------------
Setting the tree column alignment to SWT.RIGHT does not affect the data alignment in SWT too - only header text is right aligned.

Created attachment 121806 [details]
Checkbox Viewer which aligns the 2nd Column towards RIGHT

By changing the line 
 TreeColumn oc = new TreeColumn(tree, SWT.RIGHT) ;
to
 TreeColumn oc = new TreeColumn(tree, SWT.LEFT) ;

the 2nd column aligns towards left.
Comment 7 Ivan Furnadjiev CLA 2009-01-07 11:30:34 EST 
Thank you Walter, for providing this example. I've always looked at the first column with the checkboxes, which is always left justified.
Comment 8 Ivan Furnadjiev CLA 2010-04-23 08:48:14 EDT 
Fixed in CVS HEAD. The column alignment is applied to tree item text too. First column tree item text is always right aligned as in SWT.
