I would like to make a gui in the browser. Don't know if that makes<br>
sense, it's just an experiment and I want to learn web-stuff like<br>
websockets etc. Really just a programming exercise...<br>

In a quest of finding the more-most portable UI without any dependencies, I've already experimented with the very same (websocket + HTML + JS + JSON) for my moony plugin bundle [1], feel free to get inspired. It works quite well, btw.<br>
<br>
I've plans to make the web-ui code reusable, but want to migrate things to JSON-LD [2] first.<br>

P.s. please reply to the whole list next time, if not, others will miss part of the conversation.<br>

True, an UI can theoretically be anything.<br>
<br>
Can you give some more information on what you want to accomplish?<br>
You may well not need an UI in the first place (but<br>
don't know yet, as you are a beginner).<br>

<br>
ui:UI is the parent class which the Widget UIs (ui:GtkUI, ui:Gtk3UI,<br>
ui:QtUI, ...) derive from. It is en empty shell<br>
really, hosts cannot possibly know what is inside, you have to give<br>
the host some more information.<br>

<br>
If you define the UI as an ui:GtkUI, but do not return a valid<br>
GtkWidget to the host, sure this raises an error.<br>

You may be looking for ui:showInterface [1] and ui:idleInterface<br>
[2], with those you can build arbitrary<br>
UIs.<br>
<br>
Here [3] you can find a dummy plugin I use for testing various UIs<br>
in my humble host.<br>
<test_show.c> implements an as-simple-as-it-gets no-widget UI.<br>
