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.
