Here's a little showcase of something which I'm working on for a personal little project of mine, which I thought folks might like to take a look at -- an user customizable-display program.
Now, since I couldn't get $RESIZE:ON to work the way I was wanting, with a limit for size, I took it out of this program. Instead, the user here now has several options, all of which are keyboard operated:
CTRL + Arrow Keys = Resize the screen. You can make this program bigger or smaller, on the fly.
ALT + Left/Right Arrow = Increase or Decrease the size of the font on the screen. Notice that this can also change the size of the screen slightly to suit the new fontwidth and fontheight.
ALT + Up/Down Arrow = Increase or Decrease the brightness of the text on the screen. Late at night, I tend to do things with the lights off and while sitting in the dark a lot of the times, and a bright display ends up hurting my eyes. This corrects that issue by allowing us to adjust the brightness of the text so that we can might it more intense in times of high surrounding light, or turn it waaay down, if we prefer, for use in the dark.
Now, we're not actually doing anything with this program as of yet, but it does use two distinct screens for us -- a WorkScreen and a DisplayScreen. The WorkScreen is 32000 pixels in height, so we can print multiple pages of text upon it, and then display segments upon the DisplayScreen, for ease of scrolling up and down with screens which hold more than a single page of information.
I'll be adding word wrap along with the auto-resizing features, and then the basic interface will more-or-less be done for my needs. If you guys want, I'll post a version of this with a nice long page of junk and word wrap to bring it all together, but I thought I'd go ahead and share it as it is, in case anyone else would ever be interested in making use of this type of user-interactive interface. Personally, I think it'd make a nice little way to allow the user some display options for something like a text-adventure game, or any type of program which would be heavy on text usage.
As I get older, I find it's always nice to be able to make text a little bigger/smaller and brighter/dimmer, depending on the state of my poor eyes. What we have here is basically just a little plug-in routine which is ready built to handle most of that for us already. With just a few minor enhancements, I imagine this will be something which I might end up making a lot of use of in the future.
