Downloading and installing Qt 5.0.2 for Windows 32-bit (MinGW 4.7): How to get and set up Qt on your Windows machine?




If you want to use Qt 5.0.2 for Windows 32-bit (MinGW 4.7) on your Windows machine, you need to download and install it from the official Qt website. Here are the steps to do so:


Choosing the right Qt package and license model




The first step is to choose the right Qt package and license model for your project. There are two main options:


  • Qt Online Installer: This is a small executable file that downloads and installs the latest version of Qt and its components on your machine. You can choose which components you want to install and update them later. This option requires an internet connection during installation and a Qt account to log in.



  • Qt Offline Installer: This is a large executable file that contains a specific version of Qt and its components for a specific platform. You can install it without an internet connection or a Qt account. However, you cannot update or modify the components later.



In this article, we will use the Qt Offline Installer for Windows 32-bit (MinGW 4.7), which is compatible with Windows 7 or later. You can download it from this link: Qt 5.0.2 for Windows 32-bit (MinGW 4.7) Offline Installer Download. The file size is about 395 MB.


The next step is to choose the right license model for your project. There are two main options:


  • Open-source license: This option allows you to use the open-source version of Qt under the terms of GNU Lesser General Public License (LGPL) version 3 or GNU General Public License (GPL) version 2 or 3, depending on your project requirements. This option requires you to comply with the license obligations, such as disclosing your source code, providing attribution notices, linking dynamically with Qt libraries, and others.



  • Commercial license: This option allows you to use the commercial version of Qt under a paid subscription plan that grants you more rights and flexibility than the open-source license. This option does not require you to disclose your source code or comply with any license obligations. However, it requires you to pay a monthly or annual fee, depending on the plan you choose.



In this article, we will use the open-source license option for Qt 5.0.2 for Windows 32-bit (MinGW 4.7). You can read more about the license terms and conditions here: Qt Licensing.


Running the Qt online installer and selecting the components




The second step is to run the Qt offline installer and select the components you want to install on your machine. Here are the steps to do so:


  • Double-click the downloaded executable file (qt-windows-opensource-5.0.2-mingw47_32-x86-offline.exe) to launch the Qt offline installer.



  • Click Next to proceed with the installation.



  • Read and accept the license agreement and click Next.



  • Choose the installation folder and click Next. The default folder is C:\Qt\Qt5.0.2.



  • Select the components you want to install and click Next. The minimum components you need are Qt 5.0.2 for Desktop (MinGW 4.7) and Qt Creator 2.6.1.



  • Click Install to start the installation process.



  • Wait for the installation to finish and click Finish.



Congratulations! You have successfully installed Qt 5.0.2 for Windows 32-bit (MinGW 4.7) on your machine.

  • Go to Tools > Options > Build & Run > Kits.



  • Select Desktop (default) as the active kit and check that it has the following settings:



  • Device type: Desktop



  • Device: Local PC



  • Compiler: MinGW 4.7 32bit



  • Debugger: GDB



  • Qt version: Qt 5.0.2 MinGW 32bit



  • If any of these settings are missing or incorrect, you can edit them by clicking on the Manage button next to each setting.



  • Click OK to save the changes and close the Options dialog.



You have successfully checked the build and run settings in Qt Creator.


Using Qt 5.0.2 for Windows 32-bit (MinGW 4.7): How to create, build, run, and deploy Qt applications for Windows?




If you want to use Qt 5.0.2 for Windows 32-bit (MinGW 4.7) to create, build, run, and deploy Qt applications for Windows, you need to follow some steps in Qt Creator. Here are the steps to do so:


Creating a Qt Quick project or a Qt widget project




The first step is to create a new project in Qt Creator. You can choose between two types of projects: a Qt Quick project or a Qt widget project.


  • A Qt Quick project is a project that uses QML language to create dynamic user interfaces with custom components and animations.



  • A Qt widget project is a project that uses C++ language and Qt widgets library to create traditional user interfaces with standard widgets and layouts.



Here are the steps to create a new project in Qt Creator:


  • Go to File > New File or Project.



  • Select either Qt Quick Application - Empty or Qt Widgets Application under the Application category and click Choose.



  • Enter a name and a location for your project and click Next.



  • Select Desktop (default) as the kit and click Next.



  • For a Qt Quick project, select the QML file template and click Next. For a Qt widget project, select the class name, base class, and header file for your main window and click Next.



  • Review the project summary and click Finish.



You have successfully created a new project in Qt Creator.


Writing QML or C++ code in Qt Creator




The second step is to write QML or C++ code in Qt Creator. You can use the code editor to write your code and the design mode to create your user interface.


Here are some tips to write QML or C++ code in Qt Creator:


  • Use the code completion feature to insert keywords, properties, functions, and signals. Press Ctrl+Space to activate it.



  • Use the syntax highlighting feature to distinguish different types of code elements. You can change the color scheme in Tools > Options > Text Editor > Fonts & Colors.



  • Use the code folding feature to collapse or expand blocks of code. Click on the arrow next to the line number to toggle it.



  • Use the indentation feature to align your code properly. Press Tab or Shift+Tab to indent or unindent selected lines of code.



  • Use the snippets feature to insert predefined code templates. Press Ctrl+K to activate it and select a snippet from the list.



  • Use the bookmarks feature to mark lines of code that you want to revisit later. Press Ctrl+M to toggle a bookmark and Ctrl+, or Ctrl+. to navigate between bookmarks.



Here are some tips to create your user interface in Qt Creator:


  • Use the Qt Designer or Qt Quick Designer tool to drag and drop components from the library onto the canvas. You can switch between them by clicking on the Design button on the left sidebar.



  • Use the property editor to change the properties of the selected component. You can also use the text editor to edit the QML or C++ code directly.



  • Use the states editor to define different states of your user interface and switch between them. You can also use transitions and animations to create dynamic effects.



  • Use the preview tool to see how your user interface looks and behaves in different styles and resolutions. You can also run your application in debug mode or release mode by clicking on the green triangle or hammer buttons on the bottom left corner.



Building and running an example application




The third step is to build and run an example application in Qt Creator. You can use one of the many examples that come with Qt 5.0.2 for Windows 32-bit (MinGW 4.7) or create your own application from scratch.


Here are the steps to build and run an example application in Qt Creator:


  • Go to File > Open File or Project.



  • Navigate to C:\Qt\Qt5.0.2\5.0.2\mingw47_32\examples and select an example folder that you want to open, such as analogclock, calculator, or flickable.



  • Select Desktop (default) as the kit and click Configure Project.



  • Click on the Build button on the bottom left corner to build your project.



  • Click on the Run button on the bottom left corner to run your project.



You have successfully built and run an example application in Qt Creator.


Deploying a Qt application to Windows




The fourth step is to deploy a Qt application to Windows. You can use one of the following methods:


Static linking




This method involves linking your application with static versions of Qt libraries, so that you don't need any external dependencies. However, this method requires you to comply with the license obligations of Qt, such as disclosing your source code and providing attribution notices. Here are the steps to use this method:


  • Go to C:\Qt\Qt5.0.2\5.0.2\Src\qtbase\mkspecs and open the file qconfig.pri in a text editor.



  • Change the line that says CONFIG += shared to CONFIG += static.



  • Save and close the file.



  • Go to C:\Qt\Qt5.0.2\5.0.2\Src and run the configure.bat file with the -static option.



  • Run the mingw32-make command to build the static Qt libraries.



  • Go to your Qt project folder and open the .pro file in a text editor.



  • Add the line CONFIG += static to the file.



  • Save and close the file.



  • Rebuild your project in Qt Creator.



You have successfully linked your application with static Qt libraries.


Dynamic linking




This method involves linking your application with dynamic versions of Qt libraries, so that you need to distribute them along with your application. However, this method does not require you to comply with the license obligations of Qt, as long as you link dynamically with Qt libraries. Here are the steps to use this method:


  • Build your project in Qt Creator as usual.



  • Go to C:\Qt\Qt5.0.2\5.0.2\mingw47_32\bin and run the windeployqt.exe file with the path to your application executable as an argument.



  • This will create a folder named after your application in the same directory as your executable, containing all the necessary Qt libraries and plugins.



  • Copy this folder to any location you want to deploy your application.



You have successfully linked your application with dynamic Qt libraries.
