Activable | declarative UI components 2K , 0 dependency , IE8 compat | User Interface library

I want to make application unactivable.

I mean its must be inactive and non-foreground even by click on it. Active window must be the same app as it was before click on my app.

How can I do this?

upd:

1. Let's imagine some window/panel. Like a Dock. Let's call it "Docky"

2. Docky is inactive, Active window is Safari:

   ...

On a GNOME Xorg session, to get the return value of method GetIdletime exposed on DBus, you can either use

I'm coding a little 2D game, all the game elements are subclasses of GameObject. The class Game has a collection of GameObject. My problem is, when the player performs an action, I go through the collection of GameObject to find what's in front of the player and then I want to use ONLY methods of interfaces implemented by the subclasses of GameObject without using instanceof and casting.

Here is a (very) simplified class-diagram of the situation

I tried to implement the visitor pattern but I want the function visit() to take an Activable or an Obstacle as an argument and not a TV or a Wall.

Here a code example :

I may be asking a basic question, but to be honest, I have no real developement or code knowledge. I've been requested to make a prototybe of some basic app, that is supposed mainly to be buttons on screens, activable or desactivable. I've written some kind of TL;DR in case my explanations are bad

I've been coding this on Android Studio 3.0, I (hardly) managed to place PNGs files on the screen, making it looking like a button. Thing is, while some parts of the app are mainly constituted with independants togglable button. There a part where pressing a button must deselect the others. AND, if this button is pressed a second time open another activities.

Here's part of my code I'm using.

This one for independants buttons

I want to get some data from the "BATTLE_SERVER_DATA" in this piece of code off a webpage.
