Grid Layout change layout alignment of control s

[rellicott]

I have a window with multiple composites on it. I use several of the composites as place holders that I put a second composite into and then add widgets to them. I dispose of the inner or second composite and rebuild them base on user input. The issue I have is when I rebuild the composite some times I want the controls to align to the left and other times to the right. It seems that what ever the alignment is the first time I build the composite is what I am stuck with even thought I dispose of the composite and rebuild it. I tried changing the alignment on the first (place holder) composite at the same time as the rebuilt composite but that has no effect either. Anyone have any ideas why I can't change the alignment of the composite?


Sample code

if (state.commandBtnArea != null)
state.commandBtnArea.dispose();

state.commandBtnArea = new Composite(state.reuseCommandBtnArea, SWT.LEFT);
state.commandBtnArea.setVisible(true);

GridLayout gl = new GridLayout(8, false);
gl.marginHeight = 1;
gl.marginWidth = 0;
gl.horizontalSpacing = 1;
state.commandBtnArea.setLayout(gl);

GridData gd = new GridData(SWT.FILL, SWT.FILL, true, true);
gd.horizontalAlignment = SWT.LEFT;
gd.verticalAlignment = SWT.CENTER;
state.reuseCommandBtnArea.setLayoutData(gd);

gd = new GridData(SWT.FILL, SWT.FILL, true, true);
gd.horizontalAlignment = SWT.LEFT;
gd.verticalAlignment = SWT.CENTER;
state.commandBtnArea.setLayoutData(gd);

Thanks in advance.

On further review, it is not the alignment that is the problem it is the size of the recreated composite. It seems to always take the packed size of which ever composite was created first. My work around was to add some hidden field to force them to be the same size.
