编辑器保存的实现
保存编辑器的实现：
1.重写方法变更标记的实现 @Override public boolean isDirty() { return getCommandStack().isDirty(); } @Override public void commandStackChanged(EventObject event) { super.commandStackChanged(event); firePropertyChange(PROP_DIRTY); } 2.序列化所以要保存的模型包含连线 3.重写dosave方法 @Override public void doSave(IProgressMonitor monitor) { // TODO Auto-generated method stub try{ ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(new File("D:\\objectFile.obj"))); ProgrammerModel model=(ProgrammerModel)getGraphicalViewer().getContents().getModel(); out.writeObject(model); out.close(); }catch(Exception e){ System.out.println(e); } //保存快捷�? getCommandStack().markSaveLocation(); } 4打开编辑器读取保存内容 @Override protected void initializeGraphicalViewer() { // TODO Auto-generated method stub GraphicalViewer viewer = getGraphicalViewer(); ObjectInputStream ois = null; ProgrammerModel root = null; if(new File("D:\\objectFile.obj").exists()){ try { ois = new ObjectInputStream(new FileInputStream(new File("D:\\objectFile.obj"))); root = (ProgrammerModel) ois.readObject(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } else{ root=new ProgrammerModel(); root.setName(""); root.setLayout(new Rectangle(30,50,30,50)); } viewer.setContents(root); } |
