O1Library is a toolkit designed for the course Programming 1 (a.k.a. O1) at Aalto University. It contains an assortment of tools; most prominently, it provides a framework for simple graphical programming and utilities for playing sound.
This is the front page of O1Library’s documentation. However, this is probably not the best place to start learning about O1Library as a student. That’s because the relevant content of this library is introduced bit by bit in the chapters of O1’s custom ebook alongside the associated programming concepts and assignments.
You may still find this documentation useful as a reference. You can also find some optional content here that you may wish to try.
This front page lists the content available in the top-level package called simply o1.
These tools are available with the simple command import o1._ in your Scala programs.
Some of them you’ll use a lot; some of them you won’t necessarily need at all.
The tools listed here are actually implemented in a number of subpackages (o1.gui,
o1.sound, etc.); what you see here are just “shortcut aliases” to those actual
implementations. The aliases are here to make that convenient import command work and to
provide you with this list of links to some of the more commonly used tools in O1Library.
The subpackages also contain additional content not listed here.
O1Library has been developed by Aleksi Lukkarinen and Juha Sorva. Several
of the key components in o1.gui and o1.world are built upon Aleksi’s
Scala Media Computation Library.
Some parts of O1Library draw inspiration from the “teachpacks” of the Racket
programming language.
We are grateful to Riku Autio, Joonatan Honkamaa, Juhani Numminen, Leo Varis, Veera Kahva, and anonymous students for bug reports and fixes. We thank Otto Seppälä for helpful discussions.
This package contains tools for building simple GUIs.
This package contains tools for building simple GUIs. The toolkit is particularly well suited to constructing GUIs that display information as 2D images and/or geometric shapes. It is not designed for demanding graphical needs that call for high efficiency. Some of the tools in this package are built on the Swing GUI library, and the two libraries can be used in combination.
Some of the types in this package have aliases in the top-level package o1, so they are
accessible to students simply via import o1._. Some of the package contents are not available
in the top-level package or included in this documentation.
Please note: One of this package’s key components (views) comes in multiple varieties, which
which are defined in the subpackages o1.gui.mutable and o1.gui.immutable and not listed below.
The View that is most commonly used in O1 (and aliased as o1.View in the top-level package) is
o1.gui.mutable.ViewFrame.
This package exists in order to provide aliases to event classes in Swing and to add some methods to Swing’s InputEvent via o1.gui.event.ConvenientInputEvent.
This package exists in order to provide aliases to event classes in Swing and to add some methods to Swing’s InputEvent via o1.gui.event.ConvenientInputEvent.
The contents of this package are aliased in the top-level package o1, so that
they are accessible to students simply via* import o1._.
This class extends the interface of scala.swing.event.InputEvent with convenience methods.
