  42 <p class="p1">EZPopUpMenu is wrapper class which creates an (optional) label and a popUpMenu. It includes per item actions as well as a global action which are both evaluated upon selection of an item. Convenience methods for inserting and deleting menu items are also included . If the parent is nil, then EZPopUpMenu will create its own window.See <a href="EZGui.html"><span class="s2">EZGui</span></a> and <a href="EZLists.html"><span class="s2">EZLists</span></a> for all of the options.</p>

  46 <p class="p5"><b>Some Important Issues Regarding EZPopUpMenu</b></p>
  47 <p class="p2"><br></p>
  48 <p class="p1">The convenience methods for EZPopUpMenu require that the items array is an array of associations of labels and functions, not like in <a href="../Cocoa-GUI/SCPopUpMenu.html"><span class="s2">SCPopUpMenu</span></a>, where items is simply an array of strings. If <b>label</b> is nil, then no staticText is created. I</p>
