Bug 7591 Flicker when toggeling show inherited filter
When toggeling the show inherited filter in the type hierarchy you can watch the scrollbar grow. We should bracket this refresh with setRedraw(false/true) so that there is only a single refresh.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/typehierarchy/MethodsViewer.java
IMethod similar= findSimilarMethod(method, currElements);
							if (similar != null) {
								newSelectionElements.add(similar);
							}
						}
					}
				}
				newSelection= new StructuredSelection(newSelectionElements);
			} catch (JavaModelException e) {
				JavaPlugin.log(e);
			}
		}
		setSelection(newSelection);
		updateSelection(newSelection);
	}
	
	private IMethod findSimilarMethod(IMethod meth, Object[] elements) throws JavaModelException {
		String name= meth.getElementName();
		String[] paramTypes= meth.getParameterTypes();
		boolean isConstructor= meth.isConstructor();
		
		for (int i= 0; i < elements.length; i++) {
			Object curr= elements[i];
			if (curr instanceof IMethod && JavaModelUtil.isSameMethodSignature(name, paramTypes, isConstructor, (IMethod) curr)) {
				return (IMethod) curr;
			}
		}
		return null;
	}
