Default [Q] How to lock the widgets on the Android's lockscreen?

Hi,

I have Android 4.3 on Sony Xperia Z1 Compact.

On my lockscreen I have three widgets. I noticed that, when the phone is in the pocket for example, sometimes the widgets are moved around, or removed, or activated... I'd like to find a way to block / lock the widgets in the lockscreen, like that they couldn't be removed or moved around until I uncheck a box or something. So the first widget is that one, the second is that one, and the third is that one, and if I want to change the order or remove then I need to unlock/unblock my settings.

FYI I have a pattern to unlock the phone.

I haven't been able to find this option. Any idea ?

Thanks
