10 years, 4 months ago OK, due to numerous requests I wrote small and very basic but actually working example. The plugins I know of (e.g., Dropbox's) work by injecting themselves into the Finder via Mach calls-not exactly the direction I thought Apple was going at the time. 10 years, 5 months ago Any idea where I can find info on the Finder plugin interfaces mentioned (for OS X Lion)? 10 years, 5 months ago It's unfortunately not mentioned. though it's called FI_TIconAndTextCell rather than just TIconAndTextCell, though I suspect we are referring to the same class. It may be the reason Dropbox isn't avail in AppStore. Nevertheless this is the only method you can reach such functionality (icon overlays) in Finder. what you're doing does'nt seem totally legal 10 years, 8 months ago Yep, probably. 10 years, 8 months ago Yes, I too agree with. Have you achieved what you were trying to? Did you go with the Finder plugin tactics? 10 years, 9 months ago Any updates on this for lion? 10 years, 8 months ago After using this code, you can not sell your product on apple app store. 11 years, 6 months ago It's been a while since this post, with 10.6 readily available. I will just wait for the Snow Leopard public release. Besides, your plugin may not work on 10.6 anyway without a Cocoa rewrite, so it might make good sense to take a look at Snow Leopard before it gets released, regardless.ĥ years, 4 months ago Related Topics macos plugins objective-c cocoa finder Comments 13 years, 1 month ago thanks for the explanation. #Simbl plugins code#If you are lucky enough to be in a situation where you can actually only target Snow Leopard, you probably should grab an ADC Premier or higher membership, download the prerelease builds, and code against that. #Simbl plugins mac os x#On the bright side, the Finder in Mac OS X 10.6 Snow Leopard has been fully rewritten in Cocoa-and with that come vastly superior plugin interfaces. Calling the situation hysterically poor would be a vast understatement. Writing a plugin, where you're simultaneously managing old-school Carbon memory management, COM-style memory management, and Cocoa/new-style Carbon memory management, can be an incredible pain-and that totally ignores the fact that you'll be interacting in three or more radically different APIs, with different naming conventions and calling semantics. If you look at the SCFinderPlugin subproject of the SCPlugin project, you will find that it follows exactly the same techniques outlined in your first link, including setting up a vtable for COM, writing AddRef/ReleaseRef functions, and so on. Sadly, programming a Finder plugin actually does still require getting your hands dirty with COM. run.ĭue to changes in Lion some work have to be done from scratch (make new "Finder.h" file with all declarations needed in it, find proper classess and methods to override), but this technique still works. #Simbl plugins install#Then wrap in into SIMBL plugin, install SIMBL and. I know, looks weird, like loop, but actually it isn't. #Simbl plugins how to#Pay attention to this line: this is how to call 'super' in order to get normal icon and name etc. If nodeWithFENode:] fullPath] lastPathComponent] drawInRect:NSMakeRect(,, , ) fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0] Įssentially it draws "myPrettyIconOverlayImage" over every icon for file with filename starts with letter "A". (void) FT_drawIconWithFrame:(struct CGRect)arg1 Below is sample implementation for this method. I am overriding "drawIconWithFrame:" method with my method "FT_drawIconWithFrame:". Old = class_getInstanceMethod(finder_class, = class_getInstanceMethod(finder_class, new) Here's the code for method swizzling: + (void) Plugin_loadĬlass finder_class = Ĭlass_addMethod(finder_class, :") For instance to draw something over icon in ListView, drawIconWithFrame: method of TIconAndTextCell method must be overriden. Then write your code as a SIMBL plugin (refer to documentation how to do it), swizzling some methods. At first proper Finder's headers are needed. Here is what I have it done under Leopard (10.6). I know this is so old, but some may be still interested in topic (?) The Finder Icon Overlay example project represents a small and very basic but actually working example of the answer below.
