• What method can I override in GridViewHeaderRowPresenter to prevent it from drawing some columns?

  - by Carlo

  The thing is that I created a custom column that inherits from GridViewColumn, and I added a Visibility dependency property to it. Now I want to create a custom GridViewHeaderRowPresenter, that does not draw the columns when their visibility is hidden or collapsed, but other than the OnRender() method, I can't think of anything else. Thanks. Btw, the reason I'm doing this is because removing or adding columns doesn't work like we would expect it (some specs for our app) and I believe what I'm trying to do here would work if pulled out correctly.

• Which style of return is "better" for a method that might return None?

  - by Daenyth

  I have a method that will either return an object or None if the lookup fails. Which style of the following is better? def get_foo(needle): haystack = object_dict() if needle not in haystack: return None return haystack[needle] or, def get_foo(needle): haystack = object_dict() try: return haystack[needle] except KeyError: # Needle not found return None I'm undecided as to which is more more desirable myself. Another choice would be return haystack[needle] if needle in haystack else None, but I'm not sure that's any better.

• What is the "proper" method for determining if a swf is running within an AIR application?

  - by Michael Prescott

  I've got a Flex Web project and a Flex AIR project that use a common code-base. The common code defines several run-time loaded Flex Modules. I want the Flex Modules to behave differently depending on whether the running base application is WEB or AIR. What is the proper method for determining from the module code whether the module is running in a WEB or AIR application? (I found that Security.sandboxType.toString() returns "application", but I haven't found anything better in the documentation, yet.)

• How can I take any function as input for my Scala wrapper method?

  - by pr1001

  Let's say I want to make a little wrapper along the lines of: def wrapper(f: (Any) => Any): Any = { println("Executing now") val res = f println("Execution finished") res } wrapper { println("2") } Does this make sense?
