Solved #392

This PR implements globalShortcut like electron.

4 methods are implemented: register, isRegistered, unregister, unregisterAll.

I was going to implement these methods as static methods of GlobalShortcut struct. Unfortunately, Go doesn't support static method. so an alternative way is implemented. See follow examples:

// Register
astilectron.GlobalShortcutRegister("shift+1", func() {
    fmt.Println("shift+1")
})

// Is registered
astilectron.GlobalShortcutIsRegistered("shift+1")  // true

// Unregister
astilectron.GlobalShortcutUnregister("shift+1")

// Unregister all
astilectron.GlobalShortcutUnregisterAll()

TODO

  • Register
  • Is Registered
  • Unregister
  • Unregister all
  • Add test case
  • Add doc

The relevant event will no longer be triggered after the shortcut is unregistered. If the same key is registered again, the original callback will be replaced with new one.
Therefore, we don't need to find the registered key from the map. Besides, we don't need to parse the accelerator, too.

An error will be returned if the method failed.
1. Add test case
2. Add doc to README.md
3. Handle `ctx.Err` in functions

Instead of using GlobalShortcut directly here, could you:

  • create a specific EventGlobalShortcuts struct containing json fields only?
  • remove json fields from GlobalShortcuts
  • make sure you add an s at the end of all global shortcut occurences

Instead of making the Global Shortcut methods/variables global to the package, could you:

  • create a GlobalShortcuts struct that will contain the *object and registered callbacks
  • add a globalShortcuts *GlobalShortcuts variable to the Astilectron struct
  • add a newGlobalShortcuts() method that creates a *GlobalShortcuts (and does the other instantiating stuff that your InitGlobalShortcuts() does) and call this method after creating the dock
  • add a GlobalShortcuts() method to the Astilectron struct that will return a.globalShortcuts
  • add Register(), IsRegistered(), Unregister() and UnregisterAll() methods to the GlobalShortcuts struct

I do think cleaning the map is still a good idea

The reason why I didn't clean the map is that there are extra costs to determine the corresponded shortcut to be removed from the map. For example, a user registered an event with Ctrl+Shift+S then unregistered with S+Shift+Ctrl, expected that shortcut should be unregistred. Therefore Ctrl+Shift+S should be removed from the map.
A more complex case: registered with CtrlOrCmd+X then unregistered with Cmd+X, expected that shortcut is unregistered. Therefore CtrlOrCmd+X should be removed from the map.
It's too complex to determine the equivalent shortcuts, the best way is to let electron decide whether the shortcuts should be registered or unregistered.

Mmm last time I used shortcuts in JS, Ctrl+Shift+S was different than S+Shift+Ctrl 🤔 Therefore wanting to register a shortcut Ctrl+Shift+S and unregister it with S+Shift+Ctrl should not work in Electron 🤔

Nevertheless, I think it's not too much to ask the developer to be consistent in the accelerator he/she uses when registering/unregistering a shortcut. Also I'd rather keep the map the closest to reality.

Therefore, I'd rather see the map cleaned 👍

Howerver, the combination of ctrl+shift+S was unregistered successfully.

Therefore, I'd rather see the map cleaned 👍

Sure thing

I missed it in my previous reviews, but could you move callbacks to the GlobalShortcuts struct and make sure you initialize it with make(map[string]globalShortcutsCallback) in newGlobalShortcuts?
