KDE 2.0 Development, Which Is Directly Supported
23 8911 CH18 10/16/00 1:44 PM Page 401 The KDevelop IDE: The CHAPTER Integrated Development Environment for KDE by Ralf Nolden 18 IN THIS CHAPTER • General Issues 402 • Creating KDE 2.0 Applications 409 • Getting Started with the KDE 2.0 API 413 • The Classbrowser and Your Project 416 • The File Viewers—The Windows to Your Project Files 419 • The KDevelop Debugger 421 • KDevelop 2.0—A Preview 425 23 8911 CH18 10/16/00 1:44 PM Page 402 Developer Tools and Support 402 PART IV Although developing applications under UNIX systems can be a lot of fun, until now the pro- grammer was lacking a comfortable environment that takes away the usual standard activities that have to be done over and over in the process of programming. The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development. -

Tool News RENESAS TOOL NEWS on April 16, 2015: 150416/tn2 Note on Using the CS+ Integrated Development Environment When using the CS+ IDE, take note of the problem described in this note regarding the following point. Statements in source code which form a deeply-nested block 1. Products Concerned Products from the following list for which the version number of the CS+ common program is 3.00.00 to 3.01.00. - RX Family C/C++ Compiler Package (with IDE) - RL78 Family C Compiler Package (with IDE) - RH850 Family C Compiler Package (with IDE) - CS+ evaluation edition To check the version number of the product you have, refer to the following URL. https://www.renesas.com/cubesuite+_ver 2. Description CS+ might be terminated forcibly when a program is downloaded to a debugging tool or when an editor panel is opened after downloading a program. 3. Conditions Forced termination may occur when the source code for a project includes code that meets any of the following conditions. (a) { } blocks nested to a depth of 128 or more within a function. (b) 64 or more consecutive "else if" conditions are in sequence. (c) The total of double the number of consecutive "else if" conditions and the depth of the nesting of {} blocks at some point in the sequence of consecutive "else if" conditions is 128 or more. With conditions (b) and (c) above, the problem only arises when the C99 option is designated and the product is the RX family C/C++ compiler package (with IDE). 4. Workaround To avoid this problem, do any of the following. -

Using the GNU Debugger (Gdb) a Debugger Is a Very Useful Tool for Finding Bugs in a Program
Using the GNU debugger (gdb) A debugger is a very useful tool for finding bugs in a program. You can interact with a program while it is running, start and stop it whenever, inspect the current values of variables and modify them, etc. If your program runs and crashes, it will produce a ‘core dump’. You can also use a debugger to look at the core dump and give you extra information about where the crash happened and what triggered it. Some debuggers (including recent versions of gdb) can also go backwards through your code: you run your code forwards in time to the point of an error, and then go backwards looking at the values of the key variables until you get to the start of the error. This can be slow but useful sometimes! To use a debugger effectively, you need to get the compiler to put extra ‘symbol’ information into the binary, otherwise all it will contain is machine code level – it is much more useful to have the actual variable names you used. To do this, you use: gfortran –g –O0 mycode.f90 –o mybinary where ‘-g’ is the compiler option to include extra symbols, -O0 is no optimization so the code is compiled exactly as written, and the output binary is called ’mybinary’. If the source files and executable file is in the same directory, then you can run the binary through the debugger by simply doing: gdb ./mybinary This will then put you into an interactive debugging session. Most commands can be shortened (eg ‘b’ instead of ‘break’) and pressing ‘enter’ will repeat the last command. -
KDE Free Qt Foundation Strengthens Qt
How the KDE Free Qt Foundation strengthens Qt by Olaf Schmidt-Wischhöfer (board member of the foundation)1, December 2019 Executive summary The development framework Qt is available both as Open Source and under paid license terms. Two decades ago, when Qt 2.0 was first released as Open Source, this was excep- tional. Today, most popular developing frameworks are Free/Open Source Software2. Without the dual licensing approach, Qt would not exist today as a popular high-quality framework. There is another aspect of Qt licensing which is still very exceptional today, and which is not as well-known as it ought to be. The Open Source availability of Qt is legally protected through the by-laws and contracts of a foundation. 1 I thank Eike Hein, board member of KDE e.V., for contributing. 2 I use the terms “Open Source” and “Free Software” interchangeably here. Both have a long history, and the exact differences between them do not matter for the purposes of this text. How the KDE Free Qt Foundation strengthens Qt 2 / 19 The KDE Free Qt Foundation was created in 1998 and guarantees the continued availabil- ity of Qt as Free/Open Source Software3. When it was set up, Qt was developed by Troll- tech, its original company. The foundation supported Qt through the transitions first to Nokia and then to Digia and to The Qt Company. In case The Qt Company would ever attempt to close down Open Source Qt, the founda- tion is entitled to publish Qt under the BSD license. This notable legal guarantee strengthens Qt. -

Rkward: a Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R
JSS Journal of Statistical Software June 2012, Volume 49, Issue 9. http://www.jstatsoft.org/ RKWard: A Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R Stefan R¨odiger Thomas Friedrichsmeier Charit´e-Universit¨atsmedizin Berlin Ruhr-University Bochum Prasenjit Kapat Meik Michalke The Ohio State University Heinrich Heine University Dusseldorf¨ Abstract R is a free open-source implementation of the S statistical computing language and programming environment. The current status of R is a command line driven interface with no advanced cross-platform graphical user interface (GUI), but it includes tools for building such. Over the past years, proprietary and non-proprietary GUI solutions have emerged, based on internal or external tool kits, with different scopes and technological concepts. For example, Rgui.exe and Rgui.app have become the de facto GUI on the Microsoft Windows and Mac OS X platforms, respectively, for most users. In this paper we discuss RKWard which aims to be both a comprehensive GUI and an integrated devel- opment environment for R. RKWard is based on the KDE software libraries. Statistical procedures and plots are implemented using an extendable plugin architecture based on ECMAScript (JavaScript), R, and XML. RKWard provides an excellent tool to manage different types of data objects; even allowing for seamless editing of certain types. The objective of RKWard is to provide a portable and extensible R interface for both basic and advanced statistical and graphical analysis, while not compromising on flexibility and modularity of the R programming environment itself. Keywords: GUI, integrated development environment, plugin, R. -

The System Settings Handbook Chapter 1 Introduction The System Settings provides the user with a centralized and convenient way to configure all of the settings for your desktop. System Settings is made up of multiple modules. Each module is a separate application, however the System Settings organizes all of these applications into a single location. TIP Each System Settings module can be executed individually See section entitled Running individual System Settings modules for more information. System Settings groups all of the configuration modules into several categories: • Appearance • Workspace • Personalization • Network • Hardware • System Administration The modules that make up System Settings fall under one of the above categories, making it easier to locate the correct configuration module. 5 The System Settings Handbook Chapter 2 Using System Settings This section details the use of System Settings itself. For information on each individual module, please see System Settings Modules. 2.1 Starting System Settings The System Settings can be started in one of three ways: 1. By selecting Settings ! System Settings from the Application Menu. 2. By pressing Alt-F2 or Alt-Space. -
