在定制Eclipse SWT组件中实现MVC

  
public class ExampleView extends ViewPart   
{ ... public void createPartControl(Composite parent)   
{ // define a grid layout   
GridLayout layout = new GridLayout();   
layout.numColumns = 1;   
layout.marginHeight = 0;   
layout.marginWidth = 0; l  
ayout.horizontalSpacing = 0;   
layout.verticalSpacing = 1;   
parent.setLayout(layout);   
// create widgets createActionBar(parent);  
 createTree(parent);   
// add context menu and listeners  
viewer.addDoubleClickListener(this); viewer.addSelectionChangedListener(openAction);  
 // register viewer so actions respond to selection getSite().setSelectionPRovider(viewer);  
 hookContextMenu();   
}  
private void createTree(Composite parent)   
{   
viewer = new TreeViewer(parent, SWT.SINGLE  SWT.H_SCROLL  SWT.V_SCROLL  SWT.BORDER);  
viewer.setContentProvider(new ExampleViewContentProvider()); viewer.setLabelProvider  
(new ExampleViewLabelProvider());   
viewer.setSorter(new ViewerSorter());   
viewer.setInput(ModelManager.getExampleModel());   

viewer.getControl().setLayoutData(new GridData(GridData.FILL_BOTH));   
} ... }
