How can I determine the width of blockFlow?
TextFlow textFlow = new TextFlow ("Send Order");
BlockFlow blockFlow = new BlockFlow();
blockFlow.setOrientation(SWT.LEFT_TO_RIGHT);
blockFlow.setHorizontalAligment(PositionConstants.LEFT);
blockFlow.setBorder(SimpleEtchedBorder.singleton);
blockFlow.add(textFlow);
The following methods all seem to yield zero values:
dimension = blockFlow.getSize();
System.out.println("dimension.width = " + Integer.toString
(dimension.width));
dimension = blockFlow.getPreferredSize();
System.out.println("getPreferredSize = " +
Integer.toString(dimension.width));

This is because layout does not occur immediately. If it did, we would have
layed out 4 times. You need to force the update manager to run.
Normally this is not necessary. You should be querying the size/position
withing the context of a layout, in which case the block would already have
been positioned. Or, you add a listener to the figure to follow it, etc.
