  • 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.

  • Qt Framework
    About Qt Qt is a framework to develop cross-platform applications. Currently, the supported platforms are Windows, Linux, macOS, Android, iOS, Embedded Linux and some others. Genarally, it means that the programmer may develop the code on one platform but compile, link and run it on another platform. But it also means that Qt needs help: to develop software it must cooperate with development tools on specific platforms, for example in case of Windows with Visual Studio. Qt is well-known for its tools for developing graphical user interfaces (GUI) , but it also provides powerful tools for threads, networking and communication (Bluetooth, serial port, web), 3D graphics, multimedia, SQL databases, etc. Qt has its own Integrated Development Environment (IDE): QtCreator. History: 1991: version 1.0 as cross-platform GUI programming toolkit was developed and implemented by TrollTech (Norway). 2005: version 4.0 was a big step ahead but the compatibility with older versions was lost. 2008: TrollTech was sold to Nokia. 2012: Nokia Qt division was sold to Digia (Finland). 2014: Digia transferred the Qt business to Qt Company. The latest Long Term Support (LTS) version is 5.12. Official website: https://www.qt.io/ Installation The link is https://www.qt.io/download. Select the non-commercial and open source version. It may be possible that you must register yourself creating a new passworded account. Select the latest stable release and the C/C++ development system(s) you are going to use. Tip: the Qt installer proposes to store the stuff in folder C:\Qt. To avoid later complications, agree.

Sinkarenko, S. Zanzottera, V. Baggiolini, BE-CO-APS, CERN, Geneva, Switzerland Abstract technology choices for GUI, even at the cost of not using Java – our core technology – for GUIs anymore. For more than 15 years, operational GUIs for accelerator controls and some lab applications for equipment experts have been developed in Java, first with Swing and more CRITERIA FOR SELECTING A NEW GUI recently with JavaFX. In March 2018, Oracle announced that Java GUIs were not part of their strategy anymore [1]. TECHNOLOGY They will not ship JavaFX after Java 8 and there are hints In our evaluation of GUI technologies, we considered that they would like to get rid of Swing as well. the following criteria: This was a wakeup call for us. We took the opportunity • Technical match: suitability for Desktop GUI to reconsider all technical options for developing development and good integration with the existing operational GUIs. Our options ranged from sticking with controls environment (Linux, Java, C/C++) and the JavaFX, over using the Qt framework (either using PyQt APIs to the control system; or developing our own Java Bindings to Qt), to using Web • Popularity among our current and future developers: technology both in a browser and in native desktop little (additional) learning effort, attractiveness for new applications.

  • Qt-Käyttöliittymäkirjasto
    Qt-käyttöliittymäkirjasto Matti Lehtinen [email protected] 26.11.2007 Tiivistelmä Tässä raportissa tarkastellaan Qt-käyttöliittymäkirjastoa ja sen käyt- töä C++-kielellä. Raportissa tarkastellaan ensiksi Qt:n ominaisuuksia, mukana tulevia kirjastoja ja työkaluja, sekä kääntämistä. Qt:n käyt- töä tarkastellaan Qt:n tapahtumienkäsittelymekanismin kautta pienen esimerkkikoodin avulla. 1 Johdanto Graasten sovellusten tekeminen useammille käyttöjärjestelmille on usein vaikeaa, sillä kielestä riippuen pahimmassa tapauksessa sovelluksen lähde- koodi joudutaan osittain kirjoittamaan uudestaan vastaamaan kohdekäyttö- järjestelmien rajapintoja. Toinen helpompi ratkaisu on käyttää kieliä, joita voidaan emuloida tai ajaa prosessikohtaisessa virtuaalikoneessa. Tällöin kui- tenkin joudutaan hieman luopumaan suoritustehosta ja lisäksi käyttöjärjes- telmään yleensä joudutaan asentamaan tarvittavat virtuaalikoneet, emulaat- torit tai muut sovellukseen ajoon tarvittavat työkalut. Trolltech yritys tuo oman ratkaisun cross-platform-sovellusten kehittä- misongelmaan Qt-käyttöliittymäkirjaston muodossa. Qt:lla voi helposti tehdä tehokkaita natiiveja sovelluksia useammille käyttöjärjestelmille kirjoittamal- la vain yhden yhteisen lähdekoodin [1]. Sovellusten kirjoittaminen on helppoa intuitiivisen ja monipuolisen rajapinnan avulla. Lisäksi Qt:n yksinkertainen signal-slot-mekanismi tekee tapahtumienkäsittelyn turvalliseksi ja helpoksi. 2 Qt yleisesti Qt on norjalaisen Trolltech-yrityksen kehittämä useammalla käyttöjärjes- telmällä toimiva graanen käyttöliittymäkirjasto.
