If I put a Separator between two ControlContribution's in a view toolbar, each control's height on the toolbar becomes too small to see the control.
View Code:
final IToolBarManager toolBarManager = getViewSite().getActionBars().getToolBarManager();
toolBarManager.add(new MagnifyWithGridContribution("magnifyGrid", parent));
toolBarManager.add(new Separator());
toolBarManager.add(new MagnifyComboContribution("magnifyValue", parent));
ControlContribution code:

import org.eclipse.swt.SWT;

public class MagnifyComboContribution extends ControlContribution {
private final Composite notifyComposite;
private Composite c;
public MagnifyComboContribution(final String id, final Composite notifyComposite) {
super(id);
this.notifyComposite = notifyComposite;
}
@Override
protected Control createControl(Composite parent) {
c = new Composite(parent, SWT.BORDER);
c.setLayout(new GridLayout(2, false));
((GridLayout) c.getLayout()).horizontalSpacing = 0;
((GridLayout) c.getLayout()).verticalSpacing = 0;
((GridLayout) c.getLayout()).marginHeight = 0;
((GridLayout) c.getLayout()).marginWidth = 0;
final Label l = new Label(c, SWT.NONE);
final GridData data = new GridData();
data.widthHint = 26;
l.setLayoutData(data);
l.setImage(AbstractUIPlugin.imageDescriptorFromPlugin(Application.PLUGIN_ID,
IImageKeys.MAGNIFY_2).createImage());
final Combo combo = new Combo(c, SWT.NONE | SWT.DROP_DOWN | SWT.READ_ONLY);
combo
.setItems(new String[] { "1", "2", "4", "6", "8", "10", "12", "14", "16", "18", "20", "22" });
combo.setSelection(new Point(100, 1000));
combo.setTextLimit(5);
combo.setText("6");
Event event = new Event();
event.data = "magnify";
event.widget = combo;
notifyComposite.notifyListeners(SWT.Modify, event);
//combo.setToolTipText(getId());
combo.addModifyListener(new ModifyListener() {
public void modifyText(final ModifyEvent e) {
Event event = new Event();
event.data = new Object[] {"magnify", combo };
notifyComposite.notifyListeners(SWT.Modify, event);
}
});
return c;
}

I had a similar problem a long time ago (I think it was related more to
width than height). I can't remember exactly what I did to fix it, and
I don't have access to that code any more, but I seem to remember
wrapping some of the controls in ToolItem objects. You might try some
experiments like the following:
protected Control createControl(Composite parent)
{
final Button b = new Button(parent,
SWT.BORDER | SWT.CHECK | SWT.CENTER);
b.setText(...);
ToolItem toolItem = new ToolItem((ToolBar)parent, SWT.NONE);
toolItem.setControl(b);
...
return b;
}
Hope that helps a little.
