  Hi all, I have a variable of type List<RelationHeader>. Now I want to copy all the elements in this list to a new list, but I want to actually copy all the members by value (clone them). Is there a quick command to do this, or do I need to iterate over the list and copy them one at a time?

• Using HTML Canvas for UI elements?

  - by Tower

  Hi, I have a couple of UI elements such as buttons in my web application. I was going to use CSS3's transitions to animate the transition from one background-image to another. I figured out that it's not possible with the current transitions draft at least. So, I was wondering if it would make sense to use Canvas as the button. I'm sure it can handle events, so, I see no problems here. Are there any?

  - by jedierikb

  I want to change the background color of in-viewport elements (using overflow: scroll) So here was my first attempt: http://jsfiddle.net/2YeZG/ As you see, there is a brief flicker of the previous color before the new color is painted.

• Can I have a set containing identical elements?

  - by Roman

  It is convenient for me to use a set. I like how I can "add" ("remove") an element to (from) the set. It is also convenient to check if a given element is in the set. The only problem, I found out that I cannot add a new element to a set if the set has already such an element. Is it possible to have "sets" which can contain several identical elements.

• Bind an event handler to multiple elements jQuery?

  - by Alex

  Hello all. I've done some experimenting, but can't seem to successfully bind one event handler to multiple elements using jQuery. Here's what I've tried: $('selector1', 'selector2').bind('click', function() { $('someSelector').removeClass('coolClass'); }); I've tested all my selectors, and they are all valid. Is what I'm trying to do even possible? If so, can I do it with .live() as well? Thanks!
