| Operating System | Build Status |
|---|
| Linux | None |
Description
IUP is a multi-platform toolkit for building graphical user interfaces.
IUP's purpose is to allow a program source code to be compiled in different
systems without any modification. Its main advantages are:
- It offers a simple API.
- High performance, due to the fact that it uses native interface elements.
- Fast learning by the user, due to the simplicity of its API.
Installation
Get the below IUP library, or later, and install it:
mkdir libiup
cd libiup
curl -L https://sourceforge.net/projects/iup/files/3.25/Linux%20Libraries/iup-3.25_Linux44_64_lib.tar.gz > libiup.tar.gz
tar xvzf libiup.tar.gz
sudo bash install
sudo bash install_dev
cd ..
Install the Raku module with Zef:
zef update
zef install IUP
Synopsis
For convenience a IUP/Colors.rakumod file exists with 140 common colors
named by their standard English names . Which standard is the standard
is a standard problem.
WARNING:
This module is in its early stages and should be considered a Work in Progress.
The interface is not final and may change in the future.
Some of these methods also have longer names or names with underscores
instead of hyphens.
