This is a list of notable library packages implementing a graphical user interface (GUI) platform-independent GUI library (PIGUI). These can be used to develop software that can be ported to multiple computing platforms with no change to its source code.
A distinction of Swing, as a GUI framework, is in its reliance on programmatically rendered GUI controls (as opposed to the use of the native host OS's GUI controls). Prior to Java 6 Update 10, this distinction was a source of complications when mixing AWT controls, which use native controls, with Swing controls in a GUI (see Mixing AWT and ...
The original AWT was a simple Java wrapper library around native (operating system-supplied) widgets such as menus, windows, and buttons. Swing was the next generation GUI toolkit introduced by Sun in Java Platform, Standard Edition (J2SE) 1.2. Swing was developed to provide a richer set of GUI software components than AWT. Swing GUI elements ...
The Abstract Window Toolkit (AWT) is Java's original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing. The AWT is part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program. AWT is also the GUI toolkit for a number of Java ME profiles.
Tk is a cross-platform widget toolkit that provides a library of basic elements of GUI widgets for building a graphical user interface (GUI) in many programming languages. It is free and open-source software released under a BSD-style software license.
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [1] [2] [3] On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
FOCAL (acronym for Formulating On-line Calculations in Algebraic Language, [1] or FOrmula CALculator [2]) is an interactive interpreted programming language based on JOSS and mostly used on Digital Equipment Corporation (DEC) PDP series machines. JOSS was designed to be a simple language to allow programs to be easily written by non-programmers.
