Where can I get a good set of IDE icons? [closed]

Question

I'm developing a small IDE, and I'm wondering where I can find a set of IDE icons. A few google searches didn't turn anything up that was too useful. I suppose that's probably because an 'ide icon set' wouldn't get very many purchases (compared to more generic icons).

In any case, does anyone know where I can get some such icons? Certain icons such as save, load, etc I can find myself. I'm looking for more debugging-related icons.

Icons I'm interested in include:

• start debug
• step over, step into, etc
• run/debug
• view dissassembly
• etc.

I'd like some larger ones for the main toolbar, plus some mini's for to sit beside important actions in the dropdown menus.

I will very likely not be profiting from my humble IDE, but in the case that I 'go commercial', I'd like the icons' license(s) to not limit me that way. I have no problem with attribution in the about menu and in the code, however.

Finally, commercial icons are not at all off-limits if they're reasonably cheap, but I'd prefer free ones :)

Thanks!

Update: 100 rep bounty

Here is an example set of icons that would be perfect (size/style) if it included the actual icons I need. In fact I'll probably use some of those icons anyway, such as the cut, paste and save icons. I also might use the 'play' and 'record' buttons for start and create breakpoint respectively.

I'm especially looking for step/run-to-cursor icons. Preferred icon size: 22x22px.

EDIT: What about the Netbeans icons? They're the perfect size and look very nice, but I can't seem to find any information about whether or not I'm allowed to use them. I realize netbeans is opensource, but I can't figure out if I can take the icons.

EDIT: It turns out that using NetBeans icons is fine, so I'm going with that. Thanks everyone!

Answer 1

A set of icons with a liberal license can be found at http://www.famfamfam.com/lab/icons/silk/. They're not IDE specific, but there are lots of them, only 16x16 though.

You could use some of the icons from Eclipse = they are available under the same licence as the rest of Eclipse. I had a quick look at my local install of Eclipse and lots of the icons are in subfolders under configuration\org.eclipse.osgi\bundles so you could search through the .gifs under there.
