setting text color?

[PhilMo6]

Im working on making a twitch chat overlay with luapower and so far its been easy going but I cannot seem to figure out how to set color of text at all. Background color of the main window is fairly easy but otherwise iv had no luck...

Hi,

What library are you using for rendering text?

[PhilMo6]

Honestly I was just using winapi.Label, might not be possable to change text color using this from what I can see. The tr0 library might be better for my needs. I should probably sleep more, it helps when trying to figure stuff out!

Make sure to check on the lib's status before using it. Many libs in here are quite low level and some are not even finished. Generally speaking, you need to know what you're doing and understand the trade-offs of different approaches (eg. doing your own text rendering vs using WinAPI, etc).

I was thinking about using the tr0 library even though its unmaintained. Looks like itll support emojis as well as colored text.

So using ui0 iv gotten things working but now I am trying to use a text tree to have better control over text coloration. I'm having an issue when I update the content of the scrollbox that's my main chat layer. I'm trying to just set the contents text with the updated text tree to cause it to rebuild the text the segments its actually drawing. If I replace it with a string it works fine but if I replace the contents text with the updated text tree it throws an Assertion failed! message and crashes.
I'm hoping that I am just failing figure out how I am actually supposed to update the text tree of the scrollbox contents.

The important part of the error is

D:\gcc-lua\luapower\bin\mingw64....\utf8.lua:44: attempt to compare number with nil
stack traceback:

My code is here if you want to check it out. The error happens when I update the chat window so you just enter some text into the edit box.

Ah figured it out!
Had to do
chatBoxContent._text = false
chatBoxContent._text_tree = false
chatBoxContent.text_segments = false
first. Now it works perfect!
Gotta say its been rather easy to work with for the most part so thanks for all the effort you have put into this project!
