Improve kiosk mode in OSX by setting app presentation options

[bluthen]

NWJS Version : 0.42.2
Operating System : OSX

Expected behavior

nw.Window.get().enterKioskMode() could set proper kiosk settings for a alright kiosk mode.

Actual behavior

Goes into full screen only.

How to reproduce

In a nw app run nw.Window.get().enterKioskMode() move your mouse to the bottom, the task manager shows.

Possible Solution

I've attached a patch that may be a solution. I'm currently still working on trying to get a system set up that can build nw.js properly. An important thing is to set the NSApplicationPresentationOptions.

nwjs.kiosk.patch.txt

A very important part is:

NSApplicationPresentationOptions options = NSApplicationPresentationHideDock | NSApplicationPresentationHideMenuBar | NSApplicationPresentationDisableProcessSwitching | NSApplicationPresentationDisableForceQuit | NSApplicationPresentationDisableSessionTermination | NSApplicationPresentationDisableHideApplication | NSFullScreenWindowMask | NSApplicationPresentationDisableAppleMenu;

[NSApp setPresentationOptions:options];

In the past it was possible to set this through a node native call however after 0.34.0, this is not possible for reasons I don't understand. I think it must be done directly in nw, not through node.

Electron's implementation

This link is also electron's version of setting kiosk mode (SetKiosk()). You can see they set the presentation options.

Do you have proposals on how the API should be improved for this?

I may be a bit confused. Do you mean the patch nwjs.kiosk.patch.txt I added in the first post? I just thought Window.enterKioskMode() could set the presentation options, set a high window level and set activeIgnoringOtherApps.

@bluthen I just pushed your patch. It will be available in the next nightly build.
