On OS X, when you run an app bundle, the working directory of the executed process is the root directory (/), and not the app bundle's Example.app/Contents/Resources folder.

As a result, the provided example is unlikely to work, because the library needs a valid image file as the 2nd parameter to trayhost.Initialize, and if the user places an image like [email protected] in Resources folder and writes code:

// Tray icon.
iconData, err := ioutil.ReadFile("[email protected]")
if err != nil {
    log.Fatalln(err)
}

They'll get an error like:

2016/08/01 20:51:47 open [email protected]: no such file or directory

Because /[email protected] file doesn't exist.

../.go/src/github.com/shurcooL/trayhost/platform/windows/tray.c:72:9: warning: ‘return’ with no value, in function returning non-void
         return;
         ^

This removes the need to manually compute and set an alternate image.

This allows trayhost to work as expected on macOS 10.14 when using Dark Mode.

Fixes pavben/InstantShare#32.

This is needed to close https://github.com/pavben/InstantShare/issues/9.

Updated: Switch to a combined func GetClipboardContent() (ClipboardContent, error) method. It returns the contents of the system clipboard.

type ClipboardContent struct {
    Text  string
    Image Image
    Files []string
}

~~The GetClipboardFiles() []string method returns the filepaths to files that are copied to clipboard, if any.~~

~~E.g.,~~

~~GetClipboardFiles(): [/Users/Dmitri/Local/OSes/ubuntu-14.04-desktop-amd64.iso /Users/Dmitri/Local/OSes/ubuntu-12.04.2-server-amd64.iso] len(2) <nil>~~

A short version:

I should add a CONTRIBUTING.md but basically if it's non-OS-X implementation, those are not complete and can use work - feel free to take ownership there. As far as OS X stuff goes, bug fixes or obvious improvements are welcome as PRs. If you see a missing feature or want to suggest an API change (improvement), I'm glad to hear it but open an issue first. :simple_smile:

Make that text nicer and turn it into a CONTRIBUTING.md file.

shurcooL/trayhost/platform/darwin/tray.m:122:17: warning: 'setImage:' is deprecated: first deprecated in macOS 10.14

Here: https://github.com/shurcooL/trayhost/blob/master/platform/darwin/tray.m#L122

Platform: macOS Sometimes it just skips EnterLoop and so it closes the program. I have my trayhost.EnterLoop() as the last line in my code, and sometimes it just does not enter the loop and goes to the end of main.

If I launch the app, it says ***Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!'

I tried running trayhost with an arbitrary png I found online. It panicked because it decoded to image.Palletted rather than image.NRGBA.

Perhaps the invert routine could be relaxed to work more generally.

Or maybe https://godoc.org/github.com/disintegration/imaging would be a good alternative. They have a simple invert function that works on any image.

Hello again,

I was curious if there was a way to exit the gui thread from a separate thread? Since the "main" thread is stuck in the C loop the bulk of the application is running in one or more goroutines. However if something happens and the app needs to exit, the best I can do is tell the user, and when the other goroutines quit/exit/return the main loop gets stuck and cannot exit without user intervention (the rest of the app being "dead" at this point).

A workaround is to call os.Exit after some delay to allow defered functions in the other goroutines a chance to run, but that doesn't seem very good. I'm using lxn/walk for the Windows version and it has a Synchronize function https://godoc.org/github.com/lxn/walk#WindowBase.Synchronize to call funcs from the main thread/goroutine, is something like this possible? Thanks
