<span class="tt2">在设计程序时,有时我们需要动态地创建菜单, 
通常我们使用以下的语句</span><p><span class="p2">&nbsp;&nbsp;&nbsp; PopupMenu1 
:= TPopupMenu.Create(Self);<br> 
&nbsp;&nbsp;&nbsp; Item := TMenuItem.Create(PopupMenu1);<br> 
&nbsp;&nbsp;&nbsp; Item.Caption := 'First Menu';<br> 
&nbsp;&nbsp;&nbsp; Item.OnClick := MenuItem1Click;<br> 
&nbsp;&nbsp;&nbsp; PopupMenu1.Items.Add(Item);<br> 
&nbsp;&nbsp;&nbsp; Item := TMenuItem.Create(PopupMenu1);<br> 
&nbsp;&nbsp;&nbsp; Item.Caption := 'Second Menu';<br> 
&nbsp;&nbsp;&nbsp; Item.OnClick := MenuItem2Click;<br> 
&nbsp;&nbsp;&nbsp; PopupMenu1.Items.Add(Item);<br> 
&nbsp;&nbsp;&nbsp; Item := TMenuItem.Create(PopupMenu1);<br> 
&nbsp;&nbsp;&nbsp; Item.Caption := 'Third Menu';<br> 
&nbsp;&nbsp;&nbsp; Item.OnClick := MenuItem3Click;<br> 
&nbsp;&nbsp;&nbsp; PopupMenu1.Items.Add(Item);</span></p> 
<p><span class="p2">&nbsp;&nbsp;&nbsp; Item := TMenuItem.Create(PopupMenu1);<br> 
&nbsp;&nbsp;&nbsp; Item.Caption := '-';<br> 
&nbsp;&nbsp;&nbsp; PopupMenu1.Items.Add(Item);<br> 
&nbsp;&nbsp;&nbsp; Item := TMenuItem.Create(PopupMenu1);<br> 
&nbsp;&nbsp;&nbsp; Item.Caption := 'Fourth Menu';<br> 
&nbsp;&nbsp;&nbsp; Item.OnClick := MenuItem4Click;<br> 
&nbsp;&nbsp;&nbsp; PopupMenu1.Items.Add(Item);<br> 
&nbsp;&nbsp; 其实我们可以使用一种更快的方法达到同样的功能, 
但使用很少的代码, 那就是用NewLine和NewItem, 看看下面的例子, 
是不是很简单?<br> 
&nbsp;&nbsp;&nbsp; PopupMenu1 := TPopupMenu.Create(Self);<br> 
&nbsp;&nbsp;&nbsp; with PopUpMenu1.Items do<br> 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; begin<br> 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Add(NewItem('First 
Menu',0,False,True,MenuItem1Click,0,'MenuItem1'));<br> 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Add(NewItem('Second 
Menu',0,False,True,MenuItem2Click,0,'MenuItem2'));<br> 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Add(NewItem('Third 
Menu',0,False,True,MenuItem3Click,0,'MenuItem3'));<br> 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Add(NewLine); 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
// 增加一个分割棒<br> 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Add(NewItem('Fourth 
Menu',0,False,True,MenuItem4Click,0,'MenuItem4'));</span></p> 
<p><span class="p2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; end;</span></p>
