Powerbuilder：尝试设置菜单级联的当前项目
请告诉这个新手。
我有一个菜单，其对象类型设置为菜单级联。我可以很好地引用菜单中的项目，甚至可以将这些项目设置为启用或可见。但我不能做的是设置菜单的 currentItem 属性。我在屏幕的打开事件中有这样的代码。
menu qq
qq = this.menuid.item[3].item[19]
qq.visible = true //OK
qq.item[3] = qq.item[3] //OK
qq.currentitem = qq.item[3] //Error during the compile
// The line above gives the following error
// C0019: Incompatible property currentitem for type menu
我很确定这是一个简单的修复，但 PowerBuilder 还不是我的朋友
Please clue this newb in.
I've got a menu with it's object type set to menu cascade. I can reference the items in the menu just fine and I can even st the items to enabled or visible. But what I can't do is set the currentItem property of the menu. I have code like this in the open event of a screen.
menu qq
qq = this.menuid.item[3].item[19]
qq.visible = true //OK
qq.item[3] = qq.item[3] //OK
qq.currentitem = qq.item[3] //Error during the compile
// The line above gives the following error
// C0019: Incompatible property currentitem for type menu
I pretty sure it's an easy fix but PowerBuilder is not my friend yet

您需要将该项目分配给 menucascade 类型的变量。我会将代码放入 Try...Catch 块中，以防稍后修改菜单。
You need to assign the item to a variable of type menucascade. I would put the code inside a Try...Catch block in case the menu is later modified.
