Set winecfg "Graphics/Automatically capture the mouse in full-screen windows" option

[gmn42]

After (re)running the installer for Fallout 4 (and resetting the wine environment), I need to manually run protontricks 377160 winecfg and set the "Automatically capture mouse in full-screen windows" option to prevent the mouse from escaping the monitor running the game (it is a secondary monitor on a dual-head setup). It would be helpful if the installer could do this automatically, as it is a general problem with FO4 on dual-monitor setups. When this option is set, I can still access the desktop and other windows by pressing the Super key. I don't believe this option would cause problems when running on a single display setup, but that would need to be tested.

I have no idea how to script winecfg now, but will try to figure it out and contribute a patch if needed. It may well be helpful for other games supported by the installer, but I have no way to test.

First step is investigating how to automate this, the rest is easy. I do know that Winecfg is just a tool for configuring registry keys, and automating registry key modifications is fairly simple.

Here are some resources from WineHQ for people who may want to look into this:

• Configuring Wine
• Winecfg

Okay, I found the registry entry (below), but it looks like it's a supported winetricks command, so the easy fix is just to set game_protontricks=("xaudio2_7=native" "grabfullscreen=y") in gamesinfo/fallout4.sh. Should i submit a PR?

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Wine\X11 Driver]
"GrabFullscreen"="Y"

Even better if there’s a winetricks verb. Feel free to send a PR
