问题 I have been working with example stated under http://wiki.wxpython.org/PopupMenuOnRightClick . The output expected when right clicking on an item would be Perform <action> on <item selected> .

问题 I've started using Django and am going right to generic views. Great architecture! Well, the documents are great, but for the absolute beginner it is a bit like unix docs, where they make the most sense when you already know what you're doing. I've looked about and cannot find this specifically, which is, how do you set up an object_list template so that you can click on an entry in the rendered screen and get the object_detail?

问题 I am using ObjectListView instead of the standard ListView is because I wanted to word-wrap the columns. I read in several places that the only thing I need to to in order to enable word-wrapping is the set column.wordWrap to true. I did just that, but it doesn't work. What am I missing here?

I'm also not quite sure whether I need

Initialize your OLV and "delete-column" as follows: // fire cell edit event on single click objectListView1

As the user scrolls it dynamically retrieves items it needs to show from the virtual list. But what if an item is added or removed from the master list? If an item is added/removed outside of the range of indexes being shown by the list view then I would assume the list view would show the added/missing items when the user scrolls to that index. Is this

问题 I tried the demo code in demo project but I can't add new item successfully. It just add new new NULL group and NULL item. Please give me an simple example code to add new item (text and image). Thank you! Oh sorry! I forgot it. This is the first time I participate in this site. I use C#. And the code is: objectListView1.BeginUpdate(); objectListView1.AddObject(new string [] {"Hello","dfdsF" }); objectListView1.EndUpdate(); and objectListView1.BeginUpdate(); OLVListItem item = new OLVListItem
