Hi,
I have the following code in an edit part:
protected IFigure createFigure()
{
Label model = (Label) getModel();
org.eclipse.draw2d.Label label = new
org.eclipse.draw2d.Label(model.getText());
label.setOpaque(true);
label.setBackgroundColor(new
Color(null,model.getBackgroundColor()));
label.setForegroundColor(new
Color(null,model.getForegroundColor()));
label.setFont(model.getFont());
label.setTextAlignment(PositionConstants.LEFT);
return label;
}
I would expect the text to be left justified when I see the Label in the
editor, but it's not. It's always in the center. It's the same with
PositionConstants.RIGHT. Am I missing something here, or is this a bug?
Can someone else please try it? I am using 3.1M2.
many thanks,
B

Barry,
I haven't tried this, but it is possible that your Draw2D Label is only as
large as the text it contains (Therefore the text alignment won't make a
difference).
It is likely that the Draw2D Label itself is center aligned in it's parent
figure giving you the impression that the text it contains is center
aligned.
A simple way to check this out is to set the background color of the Label
to be different from the background color of it's parent.
Hope this helps,
Brian.

Thanks for the reply. No, the label is much wider than the text. I also
tried changing the background to be different than the parent's color
and it makes no difference.
If I don't get a resolution pretty soon, I will just assume a bug and
log it. I can't imagine that my code is wrong. Aligning text should be
straight forward.
thanks,
Barry

Barry,
I only suggested changing the background color as a means of verifying
that your label is indeed wider than it's text, not as a fix for the
problem.
If you haven't already, please look at the javadoc for Label -
setTextAlignment and setLabelAlignment methods. Might find some answers
there.
All the best,
Brian.

Ok, if I use setLabelAlignment(), it works. But what does that mean? The

nice, but what does it mean? What does it align to? I am interested in
positioning the text within the label, so I would presume to use the
setTextAlignment() method. This is very confusing!

Hi Randy,
I thought that's what setTextPlacement was for?
"Sets the text placement of the label relative to its icon."

You're right, that's what setTextPlacement() is for. setTextAlignment() and
setIconAlignment() determine how they're aligned based on their placement.
So, say, the text is to the east of the icon, then valid icon and text
alignments are north, center, south (any other alignment will be ignored).
Notice that when you have no icon, you can get the same effect as
setLabelAlignment(EAST) by setting the text placement to south (or north)
and text alignment to left.
Go ahead and log a bug for insufficient/confusing information. We'll update
the JavaDoc.
