How to show the content is decided by the Browser (code in
MdeModulePkg/Universal/SetupBrowserDxe). You can see this driver to know the
detail.

Subject: Re: [edk2] VFR beginner question
VFR defines only the content and not the placement of items and by default
items are listed vertically.We use the down arrow key to navigate each item.How
do i design a setup screen where items are listed horizontally and i use the
next arrow to move on to the next item on the list.I want to design something
like a bios setup screen where we use next arrow to traverse various menu items
like main,advanced, security etc.
Thanks..

I'm interested in contributing my GUI framework as a edk2 subproject, but I'll
have to clear that by my employer first. Also, I've never contributed to an
open source project before, so I'm not sure how that process works.
The process is here, and you must agree to the TianoCore Contribution Agreement
1.0.
https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/MdePkg/Contributions.txt
The edk2 is all BSD license so folks are not required to give back changes, and
we can't accept code that has non-compatible license. So for example if your
subproject contained GPL code, or code copied from a GPL project then it would
have to have a GPL license and be in its own subproject.
Thanks,

I ran into the same issues and, as far as I could find out, UEFI provides
nothing for user interface except the ability to transfer a pixel buffer to the
screen. HII and VFR aren't user interface, they are just underlying structures
that a user interface can be built upon. I ended up writing my own GUI
framework and now I have a nice mouse and buttons and scrollbars and pretty
fonts, but I had to do it all from scratch. I wrote a couple layout managers
to take care of resizing and different screen resolutions. A constraint layout
(google GWT LayoutPanel) and list layout can do almost any kind of layout you
want. I also found very little image support and ended up writing some tools
that convert png and bmp images into source files that compile into my UEFI
application. I've only done one UEFI application so far, but I built the GUI
framework as a driver so it can be used for other stuff later on.
Well, that's how I did it. Hope it helps. If anyone knows a better way, I'm
interested also.
UEFI does not specify a GUI framework as our thinking was different vendors
might want a different look, and feel. These different look and feels could
imply a different GUI API, or maybe it is just easier to port an existing
framework to UEFI so standardizing the API does not really help. If you think
about it, it makes sense. Some folks may want a Metro (don't remember new name)
look, vs a Windows XP look, vs X11 look, vs a Mac look, vs a windowless UI
look...
Currently the edk2 does text for Hii since that works everywhere. The GOP does
not run over a serial port for example.
The reason there is no GUI framework is no one has contributed one. I'm sure it
would be possible to have an edk2 subproject that was a GUI framework. So feel
free to contribute.
Thanks,
