So the first thing we'll do is set up our environment for our project, then we'll build the shell of our application and it's gui - with no functionality. Rather than giving you all of the complete files in one go - we'll do this step by step as if we were starting from scratch. So a basic understanding of C++ would be beneficial!Ĭreating the bare-bones of the application: It is possible to create QT applications using python and various other languages, but this tutorial will be C++ based. Also, QT is primarily a C++ library, so the programming language we will be using will be C++.
My listing is for debian based distros, so if you use a different distro, you may want to double check the package names.īefore we go any further - I will assume that you have all of the pre-requisites installed.
All of the packages should be available via your distros usual package management tools.Īlso, the exact name of the qt5 package you need might be sightly different on other distros. But I'm fairly certain that the qtdeclarative5-dev package will bring in everything we need for this tutorial. NOTE: I have pretty much all of the qt dev packages installed on my machine. And to connect the output of the process to the text-browser, we will be using QT's signals and slots API's.Īt a minimum - this tutorial will require g++, make, qmake and the qtdeclarative5-dev package. In order to connect the button-click to a function that will start a terminal command. When we click the button - we will start a terminal program "ls -alh $HOME/Desktop/" in a separate process and display its output in the text-browser. A button (using QT's QPushButton class) In order to answer neo's other question about connecting a button to a terminal command, we'll be developing a small QT Widgets based GUI application.
#QT CREATOR DESIGN GREYED OUT SOFTWARE#
It is developed and maintained by the same people who develop the QT libraries and is an excellent piece of software to use for quickly building QT based applications.īefore trying to build QT programs from the command-line, I would personally recommend using QTCreator for your first few projects, until you have built up a bit more of a working knowledge of the QT application framework, its components and features.Īnyway, neo wanted to know if it is possible to create a QT GUI without QTCreator - it is - and this tutorial will show you how. QTCreator is an IDE (Integrated Development Environment) for QT. We'll also address the button related question too. So the aim of this tutorial is to create a simple QT based GUI application from the command line without having to use QTCreator. Is it possible to create a QT based GUI application in the terminal without using QTCreator? How can I link a QT button to a terminal command?Ģ. The questions essentially boiled down to:ġ. I've put together a little tutorial, which hopefully answers his questions.īut I've decided to post it in it's own thread, as a piece of stand-alone content for the rest of the community. In this thread user asked a couple of QT related questions.
