It's a general purpose user interface library

I'm developing widgets for my User Interface library. I'm starting from almost nothing because it's embedded and I've rolled my own cross platform graphics and UI libraries. Anyway, I've developed a label, a slider, two buttons, an image control, an "svg box", and a canvas. Controls *cannot* contain other controls. Since it is a touch screen, I'm only using one "mouse button" even though it supports gestures - I'm not dealing with those, nor should they be required. The screens are typically small - commonly 320x240 or smaller. This means that text entry is not realistic. What should I develop next, preferably a few in order of ease-of-implementation:usefulness in hopefully good ratios? I was thinking a drop down list, but for reasons this is extremely complicated. I will eventually do it but meh. Scroll bars aren't very useful by themselves as touch screens usually swipe to scroll. A dial style control might be useful but I have to be very careful there for performance reasons. Any ideas?

One thing that I have used for my IoT projects a lot is some form of slider control, either horizontally or vertically.And usually very intuitive when using touch screens...

That was the first interactive SVG** based widget that I built. :) My UI and graphics libs support SVG, and I've been using that to render the bits of my widgets because it looks nice.

Radio buttons and checkboxes. Maybe some static lists, like a bullet list or numbered list.

There is not enough room for one of those on an IoT screen. That's why IoT widgets don't have text entry, typically relying on the user to spit bluetooth or wifi at it from a phone or PC for stuff like that.

The "most common" icon is 32x32. 32x24 is also manageable (24x24 being the usual). At 320x240, that gives a potential of at least 100 keys. In other words, enough for keys, shifting, and a text box. My PC app uses (my) "standard" 48x44 for all buttons; which scales to 43 in. or a tablet. (And yes, my app also has a pop up keyboard; with a "split" option)

You still have to have room to touch it though. A lot of these screens are like 2.5" diagonal. I mean, it might be doable, but it would be rarely used.

That's an idea, but 90% of the time it would be used like text entry on a smart TV - that is to enter an SSID and wifi password and then just ride it from there. Entering passwords that way is horrible. To that end Texas Instruments developed a Bluetoothish protocol for shooting wifi creds at IoT devices from a phone and most connected chips support it. From a strictly use case scenario because of all that text entry is not common, and not nearly as useful as it would be on a PC or even a phone.

There you go… Text entry with an nearby bluetooth device? Encrypted! Is there a standard bluetooth protocol for bluetooth keyboards?
No there's not. Not all MCUs have BT anyway. It won't be part of my UI lib. It's out of scope.

Maybe a slider control could be useful. Edit: I see it's already been suggested, and you already have one :)
