AE二次开发技巧之撤销、重做

   

      可以把AE自带的重做、撤销按钮或工具添加到axToolBarControl上，再把axToolBarControl工具条隐藏，同时，在自定义的工具条上新建对应的按钮，按下此按钮实际触发的是AE自带的按钮功能！如在基础平台上的撤销！

 

代码如下：

//开始定义工具条

IOperationStack operationStack = new ControlsOperationStackClass();
            axUndoRedoToolbar.OperationStack = operationStack;
            axUndoRedoToolbar.SetBuddyControl(mainMapControl.Object);
            axUndoRedoToolbar.Hide();

//撤销

 private void tlBtnUndo_Click(object sender, EventArgs e)
        {
            IOperationStack operationStack = axUndoRedoToolbar.OperationStack;

            //Do the following to undo the previous operation on the stack.
            try
            {
                if (operationStack.UndoOperation != null)
                {
                    operationStack.Undo();//调用AE自带重做指令
                }
                else
                {
                    MessageBox.Show("没有可撤消的操作！");
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString(), "无可撤消操作");
            }
        }

 

//重做     

   private void tlBtnRedo_Click(object sender, EventArgs e)
        {
            IOperationStack operationStack = axUndoRedoToolbar.OperationStack;

         try
            {
                if (operationStack.RedoOperation == null)
                {
                    MessageBox.Show("没有可重做的操作！");
                }
                else
                {
                    operationStack.Redo();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString(), "无可重做操作");
            }
        }
