UI framework based on the Fusion/libui.cr library, with custom elements from watzon/cru.
Currently avaliable Crystal UI frameworks are either not maintained anymore or the documentation is scarce and a single error might cause a developer to lose motivation, which is why I decided to build IU on top of the LibUI framework which is a multi-platform powerful UI toolkit.
- Horizontal box, Vertical box, Checkbox, Combobox, Editable combobox.
- Button, Font button, Color button, Radio button.
- Datetime picker, Progress bar, Slider, Spinbox.
- Text entry, Multiline text entry.
- Form, Grid, Group, Table, Tab, Separator.
- Image, Label.
- Window, Menubar, Area.
- Many more.
- Mac OSX
- Linux
- Windows (Once crystal will be available on Windows)
