Monkey patching the network applet

[Herczeg Zsolt <zsolt94 gmail com>]

HI!

Can you help me please making an extension?

I would like to make an extension with the same result as adding this after 1602 line to the 
/usr/share/gnome-shell/js/ui/status/network.js
this.menu.addSettingsAction("Old network managger", 'nm-connection-editor.desktop');

If I put this directly to the file, it's perfectly works. (Adds a new settings entry, which launches the old-style network managger window)

I wanted to make an extensions, to do this without touching the network.js, but I can't get it work:

const network = imports.ui.status.network;

let network_init = null;

function init() {
    network_init = network.NMApplet.prototype['_init'];
    global.log('OLDNETWORK: Original func:');
    global.log(network_init);
    //global.log('OLDNETWORK: Menu add function:');
    //global.log(network.NMApplet.menu); //This is undefined
}

function enable() {
    global.log('Bekapcsolva');
    network.NMApplet.prototype['_init'] = function() {
        global.log('OLDNETWORK: Successful change!!');
        let ret = network_init();
        this.menu.addSettingsAction("Old network managger", 'nm-connection-editor.desktop');
	return ret;
    }
}

function disable() {
    network.NMApplet.prototype['_init'] = network_init;
}

Actually as the output of global.log(network_init); i don't receive the source code found in network.js, it's just some wrapper, and the global.log('OLDNETWORK: Successful change!!'); never runs. (So it never adds the menu item.)
I also tried to add the menu item from the extension, but the network.NMApplet.menu is undefined, so I can't run it.


I'm new to developing gnome-shell extensions, but I would like to learn making and publishing them. Can you help me where to look for the solution?

Thanks:
