private List selectionList = null;
private Clipboard clipboard = null;
private DiagramView model=null;
/**
* @param part
*/
public CopyAction(IWorkbenchPart part) {
super(part);
// TODO Auto-generated constructor stub
}
public Clipboard getClipboard() {
if (clipboard == null) {
return null;
}
return clipboard;
}
protected void init() {
setId(ActionFactory.COPY.getId());
setText("Copy");
setToolTipText("Copy");
ISharedImages sharedImages =
PlatformUI.getWorkbench().getSharedImages();
setImageDescriptor(sharedImages.getImageDescriptor(
ISharedImages.IMG_TOOL_COPY));
setDisabledImageDescriptor(sharedImages.
getImageDescriptor(
ISharedImages.IMG_TOOL_COPY_DISABLED));
setEnabled(false);
}
public void run() {
getClipboard().setContents(selectionList);
}
/* (non-Javadoc)
* @see org.eclipse.gef.ui.actions.WorkbenchPartAction#calculateEnab led()
*/
protected boolean calculateEnabled() {
// TODO Auto-generated method stub
selectionList = getSelectedObjects();
System.out.println(">>>>*****@@@"+selectionList.size());

}
/**
