Hi,
I have a problem with the CoolBar...
After the creation of the CoolBar if an user
change the CoolItem's placement for the multi-lines
form, then any Control which is placed under CoolBar
will be truncated without do layout...
Does it exist any possibility to layout the Control after
any changes?

Thanx a lot,
V.

P.S. Here you can find the exemple:

package testAndTest;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.CoolItem;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.CoolBar;

public class Test
{
public static void main(String[] args)
{
Display display = new Display ();
Shell shell = new Shell();
{
final GridLayout layout = new GridLayout();
layout.numColumns = 1;
layout.marginHeight = 0;
layout.marginWidth = 0;
layout.horizontalSpacing = 0;
layout.verticalSpacing = 0;
shell.setLayout(layout);
}
{
final CoolBar coolBar = new CoolBar(shell, SWT.NONE);
coolBar.setLayoutData(new
GridData(GridData.HORIZONTAL_ALIGN_FILL));
for(int i = 0; i < 10; i++)
{
final CoolItem coolItem = new CoolItem(coolBar,
SWT.DROP_DOWN);
final Button button = new Button(coolBar, SWT.FLAT);
button.setText("Button " + i);
coolItem.setControl(button);
coolItem.setSize(coolItem.computeSize(SWT.DEFAULT,
SWT.DEFAULT));
}
}
{
new Label(shell,
SWT.SEPARATOR|SWT.HORIZONTAL).setLayoutData(new
GridData(GridData.FILL_HORIZONTAL));
}
{
new Composite(shell, SWT.BORDER).setLayoutData(new
GridData(GridData.FILL_BOTH));
}
shell.open ();

while (!shell.isDisposed()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}

Thnaks, but I found another solution for all layouts:
it needs just to add:
coolBar.addListener(SWT.Resize, new Listener()
{
void handleEvent(Event e)
{
shell.layout();
}
});

Now I have other question: How can I force the repaint event for the
Control. The solution such as control.getParent().layout(true/false)
does not solve my problem.

Thanx a lot.

Control.redraw() will cause a paint to be queued in the operating system.
Control.update() will flush outstanding paints. Composite.layout() deals
with positioning and resizing only.

Question: Why does everyone get this wrong and assume that layout() causes
repaints (even when no sizes change)? Does AWT do it this way?
