scurses's Issues

Add method to remove widgets from FramePanel

It would be nice to be able to either completely reset a frame panel or remove some of the widgets. As I understand they can only be added currently. I had to resort to modifying the internal state of FramePanel to achieve this. Can also contribute this if it is considered welcome feature.

Also great library, used it and loved it :)

Support for dotty?

Any chances to enable releases for Scala 3? I can use this as 2.13 library however, a few packages conflict like sourcecode

SIGWINCH not supported in Windows

During the init the library creates a SIGWINCH to try and get the terminal size, but this signal does not work in Windows.

Including Scurses with SBT

Could you update the documentation to explain how to include Scurses in another project using SBT?

Release project

Could you release the project so that it can be used as a dependency in other projects? For example on Bintray.

Question about create a 'console' window

I was thinking that have a small window running along the bottom of the 'screen' that could expose a console prompt and accept custom commands to execute in the background.

Does scurses have the ability to integrate with a library like scala-jline to target stdin and stdout/stderr to a single "frame" within a scurses screen?

Question

Any hint to use it inside Cats Effects?
Direct encapsulation (calling main example functions inside and IO block) does not work, maybe due to threads?

Screenshots

example app crashes horribly

OS: MacOS BigSur 11.6
Terminal: iTerm/Kitty

steps to reproduce:

small terminal

git clone https://github.com/Tenchi2xh/Scurses && cd Scurses
sbt onions/run
after the sbt start the following is printed, but the process then hangs and I need to kill it by sending SIGTERM

if I use a bigger terminal output is refreshing every second or so and wiping the screen blinking ocasionally

changing the terminal size crashes the application.

Input does not support non-ASCII characters

It would be really nice if Input supported non ASCII characters such as á ã お etc. Assuming the terminal is configured with a font that supports those characters.
