Qt Creator is a cross-platform integrated development environment IDE built for the maximum developer experience. Qt Creator runs on Windows, Linux, and macOS desktop operating systems, and allows developers to create applications across desktop, mobile, and embedded platforms.
It features code completion, syntax highlighting, refactoring and has built-in documentation at your fingertips. Qt Creator integrates with most popular version control systems, including Git, Subversion, Perforce, and Mercurial. Import an existing project or create one from scratch — Qt Creator generates all the necessary files.
Support for Cmake and cross-compiling with qmake is included. Build for and run your software on desktop, mobile and embedded operating systems. The build settings allow you to easily switch between targets.
Test and debug applications in conditions practically identical to those on your target device. Compile source code into native machine code, accelerate start-up time and UI performance, and protect your source code and intellectual property.
It helps you rapidly design and build Qt Quick applications and components — from scratch or based on ready-made UI controls. Qt Designer is a powerful cross-platform GUI layout and forms builder.

Building and deploying can be done using either Xcode or Qt Creator. We will look at that in more detail in the next section. The minimum deployment target for Qt applications is specified in Supported Platforms. You can download the Qt 5 installers from the Downloads page. For more information, see Getting Started with Qt. Before installing Qt, you first need to install Xcode.
You will find it in the Mac App Store here. Note: As recommended by Apple, you should always use the latest Xcode version when building your applications for the App Store. In practice this means you also need the latest version of macOS to develop apps with Qt, due to Xcode's system requirements.
For running Qt applications on your Mac or in the simulator that comes with Xcode, this is all you need. Before building any Qt applications, you should test that Xcode is set up correctly, for example, by running one of the standard Xcode application templates on your device.
As mentioned previously, the development workflow consists of maintaining a normal. Note that you must re-import the project if its setup changes, for example, when adding or removing source files. You can find information on how to set up and run Apple mobile device applications in Qt Creator's manual:.
To enable this mode, suffix your source files with. This makes it possible to use frameworks from Apple's Developer Library in Qt applications.
In Qt Creator, tested examples on iOS can be looked up. Use the ios keyword to search for examples in the Qt Creator Welcome mode.

Am I getting the error because I didn't install a Qt library? Found the issue. Qt Creator wants you to use a compiler listed under one of their Qt libraries.
Use the Maintenance Tool to install this. Open Kits tab. Choose it. Now select something like Qt 5.
From now you should be able to create, build and run empty Qt project. Though OP is asking about Windows, this error also occurs on Ubuntu Linux and Google lists this result first when you search for the error"QtCreator: No valid kits found". This question is answered here and herethough those entries are less SEO-friendly No valid Kits found.
The problem occur because qt-creator don't know the versions of your qt, your compiler, or your debugger. For this let's solve the Qt versions. It may normally solve the other. You try to create a new project, run select a kit and then there is no kit available in the list. If it's Nonechange it to one of the versions available to you in the Qt versions tab which is just next to the Kits tab.
For QT 5. Just go to your OS Terminal and write sudo apt-get install qt5-defaultgo back to QT Creator and Start your New Project, and there you see the kit option Desktop included in the list. Another way to solve this issue I did it on Ubuntu While going through the installation steps, when you reach the step where you choose which packages to install via check boxes, instead of just pressing next with the default "Tools" checkbox selected also check the box for the version of QT you would like in addition to the "Tools" box.
I usually check the first box which is the latest version of QT. Learn more. QtCreator: No valid kits found Ask Question. Asked 5 years, 6 months ago. Active 8 months ago. Viewed k times.

Active Oldest Votes.This tutorial will explain in detail how to take your first steps in programming with Qt using the Qt Creator integrated development environment IDE. If you want to learn how to make powerful GUIs with all the latest fancy technologies, this is not the tutorial for you. This is firmly intended as a gentle introduction to help beginners get up and running without scaring them.
Basic Qt Programming Tutorial
We will begin by creating a new Qt-based project and modifying the generated code to show a very simple graphical user interface GUI. Once our basic application project is in place and running, we will go back and modify it to do some slightly useful things. We will start off simple and build up in complexity as you get more familiar with the widgets and other facilities at your disposal.
The open source downloads can be found on the qt. For commercial use consider getting a Qt Commercial license. To do this follow these simple steps:.
Click on that and designer will switch to design mode and open up the file. You should see a blank widget. Now do this:. Do similarly for a Line Edit and place it to the right of the Label. The exact position is not important. Click on the widget background so that both of your new widgets the label and line edit get deselected. In the toolbar at the top click on the "Lay out Horizontally" button or press Ctrl-H to add all widgets to a horizontal layout. The layout will take care of resizing your widgets for you if the parent widget's size changes.
Click on the Edit mode button in the left hand panel of creator to switch back to the text editor. You will probably see the raw xml content of the UI file at this point. Just close it we are done with it for now. Now build Hammer icon in lower left or default shortcut of Ctrl-Shift-B and run the application green "play" icon in lower left corner.
You will see some compiler messages go past in the "Compile Output" panel at the bottom whilst building.
As you can see the main function is very simple.The editor has features such as syntax highlighting and autocompletion. Clang is also supported. Development of what would eventually become Qt Creator had begun by or earlier under transitional names Workbench and later Project Greenhouse.
This was at a time when the standalone Qt Designer application was still the widget layout tool of choice for developers. There is no indication that Creator had layout capability at this stage. The record is somewhat muddied on this point perhaps due to changes in ownership or the emphasis on Qt Quickbut the integration of Qt Designer under Qt Creator is first mentioned at least as early as Qt 4.
Qt Creator includes a project manager that can use a variety of project formats such as. A project file can contain information such as what files are included into the project, custom build steps and settings for running the applications.
Qt Creator includes a code editor and integrates Qt Designer for designing and building graphical user interfaces GUIs from Qt widgets.
The code editor in Qt Creator supports syntax highlighting for various languages. It is possible to compose and customize the widgets or dialogs and test them using different styles and resolutions directly in the editor. Widgets and forms created with Qt Designer are integrated with programmed code, using the Qt signals and slots mechanism.
Qt Quick Designer is a tool for developing animations by using a declarative programming language QML. Build settings allow the user to switch between build targets, different Qt versions and build configurations. For mobile device targets, Qt Creator can generate an installation package, install it to a mobile device that is attached to the development computer and run it there. Installation packages can be published on the Ovi Store.
Qt Simulator is a tool for testing Qt applications that are intended for mobile devices in an environment similar to that of the device. From Wikipedia, the free encyclopedia.
