An Epic Introduction to PyObjC and Cocoa

August 22, 2008 PyObjC is one of the most helpful projects I have ever used, but a number of individuals have been having trouble getting started with PyObjC on Leopard because the documentation is in a bit of a disarray. In particular, there didn't seem to be a comprehensive tutorial that could introduce a newcomer to all the important aspects of PyobjC, and that was completely up to date. Here is my attempt to fill that void. With a vengeance.

Cocoa Drag and Drop text into the Dock Icon

August 7, 2008 I spent much too long today trying to figure out how to implementing drag and droping selected text onto an application's Dock icon (and its Finder icon as well), and will proceed to share this knowledge with you in the hopes that related searches will not leave their queriers quite as lost as I was.

Opening Files With Associated App in Cocoa

April 5, 2008 Recently I spent a while trying to figure out how to open files in my Cocoa app. Not just open them, but have the correct application launch with that file as an argument. I knew that Carbon achieved this with LaunchServices, but was unsure about the Cocoa equivalent to LaunchServices. But, it turns out to be quite easy to use. (Hint: its NSWorkspace.)

Epic PyObjC, Part 3: Browsing, Caching, Indicating

August 25, 2008 In this third segment of the Epic Introduction to PyObjC and Cocoa we spend some time in the standard application development workflow of iterating new idea from concept into feature. First, we have double clicking an entry open its page on, then add disk based caching of results, and we end by adding an indicator to reassure users that the app hasn't frozen while retrieving data from Metaweb.

Deleting From NSOutlineView With the Delete Key

August 21, 2008 I was trying to figure out how to delete items from an NSOutlineView with the delete key (and without simply binding the delete key to an NSButton), and it took a bit longer than necessary to figure it out. Here is a simple example that will hopefully help out those in a similar situation.
