nevow - alternating row colors?
If I have a table, and I want the background colors to alternate, how would I do that in Nevow? __________________________________________________________________ Switch to Netscape Internet Service.

You just supply multiple pattern nodes with the same name, and nevow will cycle through them when it is copying them. For example, if you are rendering a list of items in a table, you would supply more than one 'item' pattern node: <table nevow:render="sequence" nevow:data="whatever"> <tr nevow:pattern="item" style="background-color: blue"> ... </tr> <tr nevow:pattern="item" style="background-color: red"> ... </tr> </table> dp
One option is to use the :even and :odd (iirc) selectors of CSS. Another way is to have multiple patterns with the same name; the coresponding patternGenerator will then alternate between them. For example, if you have this template: <table n:render='fu'> <tr n:pattern='item'><td>111</td></tr> <tr n:pattern='item'><td>222</td></tr> </table> and this code: def render_fu(self, context, data): pattern = context.patternGenerator('item') content = [pattern() for _ in xrange(4)] return context.tag.clear()[content] you will get a table 111 222 111 222 render_sequence is a builtin renderer that works like this already. If you have some data in a sequence and each one outputs a row, render_sequence is probably what you want. The docstring is in rend.py; you can pydoc nevow.rend.sequence to see it.

I think it's nth-child(even) actually but that's a CSS3 selector and has little (if any) browser support yet.

Not strictly with Nevow, but it works nicely...
