IKImageBrowserView for ASOC

Hi All!

I’d like to learn how to inplement an Image Browser using AppleScriptObjC. I’ve been trying to follow the Image Kit programming guide, but I’m having a difficult time translating the cocoa bindings and methods over to an applescript-cocoa app. I imagine this is something ASOC’ers have done before, but I haven’t found any examples or threads on this topic. Any help would be greatly appreciated!



Here is a controller script to get you started. I have just pulled this out of an old ASOC project where I was experimenting. I think this is the project on my website here. THImage is the project you require.


All the best

I have the same question, I’d love to inspect the link you posted tellboy because I don’t quite understand how to bind the properties in your script to my interface. Unfortunately though your link is no longer active, has it been reposted anywhere else?
