[Android-development] Forcing native menubar to show

[maitai at virtual-winds.org]

Hello,
I am trying on a rather old tablet running Android 4.0.4 (api level 15). 
This device does not have physical keys at all, all is managed from the 
android system status bar which shows 3 or 4 icons depending on the 
case. The fourth icon is the option menu (the 3 vertical dots), and is 
missing when my qt application is running, although I do have a menubar 
in my QMainwindow. I discovered that if I specify uses-sdk 
android:targetSdkVersion="10" then the icon is here, but nothing happens 
when I press it, so it's rather useless. I also tried a variety of 
themes with no luck.

After some more digging, I found out that one could do something like 
that:
...
     boolean hasMenu = ViewConfiguration.get(this).hasPermanentMenuKey();
     if(!hasMenu){
         //getWindow().setFlags(0x08000000, 0x08000000);
         try {            
getWindow().addFlags(WindowManager.LayoutParams.class.getField("FLAG_NEEDS_MENU_KEY").getInt(null));
           }
...

but I don't know how to call something like that from qt application...

So I am still at lost on that one :)

Thanks for any hints,
Philippe
