是否可以在Qt(Golang绑定)应用程序中使用Sparkle?

已采纳

We build a Qt app using: https://github.com/therecipe/qt. Now we need an auto updater and found this: https://sparkle-project.org

Looks like it is being used by multiple apps on my machine:

/Applications/VLC.app/Contents/Frameworks/Sparkle.framework
/Applications/Adium.app/Contents/Frameworks/Sparkle.framework
/Applications/TeamViewer.app/Contents/Frameworks/Sparkle.framework
/Applications/Docker.app/Contents/Frameworks/Sparkle.framework
...

Some articles show me how to use it in Qt:

but it's for C++/Objective C code.

Is it possible to use with Golang? If so, how?

    sparkle.m:

    #import <Headers/SUUpdater.h>
    
    static SUUpdater* updater = nil;
    
    void sparkle_checkUpdates()
    {
        if (!updater) {
            updater = [[SUUpdater sharedUpdater] retain];
        }
    
        [updater setUpdateCheckInterval:3600];
        [updater checkForUpdatesInBackground];
    }
    

    sparkle.go:

    // +build darwin windows
    
    package main
    
    /*
    #cgo CFLAGS: -I ${SRCDIR}/Sparkle.framework
    #cgo LDFLAGS: -F ${SRCDIR} -framework Sparkle
    
    void sparkle_checkUpdates();
    */
    import "C"
    
    func sparkle_checkUpdates() {
        C.sparkle_checkUpdates()
    }
    

    And in main.go, call that func:

    action := widgets.NewQMenuBar(nil).AddMenu2("").AddAction("Check for Updates...")
    // http://doc.qt.io/qt-5/qaction.html#MenuRole-enum
    action.SetMenuRole(widgets.QAction__ApplicationSpecificRole)
    action.ConnectTriggered(func(bool) { sparkle_checkUpdates() })
