Bug 403629

Description Tim Buschtoens 2013-03-18 09:32:28 EDT

It is possible that the scrollbar thumb is rendered a it's rightmost positon while the table can actually scroll further. To reproduce, add this method to TableTab.java (Controls Demo) and call it in createStyleContents:

  private void createHideColumnControl() {
    Composite composite = new Composite( styleComp, SWT.NONE );
    RowLayout layout = new RowLayout(  SWT.HORIZONTAL );
    layout.center = true;
    composite.setLayout( layout );
    Label label = new Label( composite, SWT.NONE );
    label.setText( "Column" );
    final Text text = new Text( composite, SWT.BORDER );
    Util.textSizeAdjustment( label, text );
    text.setText( String.valueOf( columns - 1 ) );
    Button button = new Button( composite, SWT.PUSH );
    button.setText( "Hide" );
    button.addSelectionListener( new SelectionAdapter() {
      @Override
      public void widgetSelected( SelectionEvent event ) {
        try {
          int index = Integer.parseInt( text.getText() );
          TableColumn column = table.getColumn( index );
          column.setWidth( 0 );
        } catch( Exception e ) {
          // ignore invalid column
        }
      }
    } );
  }

Now run the controls demo and make column 1 or two very large. Then click first "hide", then "show".

I have not tried this yet with Tree or Nebula Grid. I don't think it's a recent regression.
