The installer framework supports various target platforms, including Windows, Linux, and macOS. In this article, we’ll walk you through the basic steps of setting up the Qt Installer Framework.

Installing Qt Installer Framework

The first step to setting up the Qt Installer Framework is installing it. The installer framework is part of the Qt development framework, so you’ll need to install Qt before you can use the installer framework.

To install Qt, go to the Qt download page, and download the installer appropriate for your system. Run the installer, and select the components you want to install. You’ll need to select the Qt Installer Framework component if you want to use the installer framework.

Once you’ve installed Qt, you can check if the installer framework was installed by running the following command in your terminal or command prompt:

$ qtifw-opensource-installer -version

This command should output the version number of the Qt Installer Framework, indicating that it’s installed and ready to use.

Setting Up Your Project

Before you can create an installer package for your application, you’ll need to create a project for the installer framework. You can do this using the Qt Installer Framework wizard.

Launch the wizard by running the following command in your terminal or command prompt:

$ binarycreator

The wizard will guide you through the process of creating a new project. You’ll need to specify the type of project, the target platforms you want to support, and the location of your installer files. You’ll also need to specify the components and features of your application that you want to include in the installer package.

Once you’ve created your project, you can modify it by editing the configuration file. The configuration file specifies the properties of your installer package, including the installer application name, version number, and platform-specific settings.

Building Your Installer Package

Once you’ve set up your project, you can build your installer package using the Qt Installer Framework tools.

To build your installer package, run the following command in your terminal or command prompt:

$ installer-framework/packages/mac/QtInstallerFramework/examples/simple/build-and-install.sh

This command builds your installer package and installs it on your system. If you want to just build your installer package without installing it, run the following command:

$ installer-framework/packages/mac/QtInstallerFramework/examples/simple/build.sh

When the build process completes, the installer package will be located in the output directory. You can distribute this package to your users as you would with any other software package.

Customizing Your Installer Package

The Qt Installer Framework provides many customization options that you can use to tailor your installer package to your specific needs.

For example, you can add a custom logo to the installer application by including the logo file in your project and configuring the installation script to display the logo.

You can also customize the installer interface by creating your own installer pages using Qt Designer and integrating them into the installer package.

Overall, the Qt Installer Framework provides a flexible and powerful tool for creating professional-looking installer packages for your applications. By following these basic steps, you can quickly get started with the installer framework and start distributing your applications to users on different platforms.

Configuring & Customizing the Installer

When it comes to creating installers for our software, the Qt installer framework is a powerful tool to have in our toolkit. Qt installer framework enables us to create cross-platform installers that come with a wealth of features to ensure our users can install our software with ease and peace of mind.

However, every software has different requirements and may have specific features that need to be included in the installer. This is where configuring and customizing installers becomes a crucial part of the development process.

In this article, we’ll dive deep into the configuration and customization of installers using the Qt installer framework.

Configuration Parameters

Before we go any further, it’s important to understand what configuration parameters are. Configuration parameters are values that we set in the installer script to customize the installer. These values can range from simple things like the installer title and icon to more complex things like the installation path, components to install, and the behavior of the installer.

Let’s start by taking a closer look at some of the more common configuration parameters:

• TargetDir: This parameter defines the default installation directory for the software. By default, this is set to C:/Program Files/Company Name/Product Name.
• Component: This parameter is used to define the components that will be installed by the installer. Components can be used to group files, libraries, and plugins that are required for certain features or functionalities of the software to work properly.
• LicenseFile: This parameter is used to specify the path to the license file that will be displayed during the installation process. If no license file is provided, the installer will skip this step.
• WindowTitle: This parameter defines the title of the installer window.
• WindowIcon: This parameter is used to define the icon that will be shown in the installer’s title bar.

These parameters are just a small sample of the many configuration parameters that we can use in the installer script. But by taking advantage of these parameters, we can greatly enhance the user experience of our software.

Customizing the Installer Pages

While configuration parameters are important, customization of installer pages is where we can truly make an installer our own. Qt installer framework offers a wide range of customization options that enable us to create custom installer pages that match the look and feel of our software.

Qt installer framework comes with a set of default installer pages that cover the basic installation process like introduction, license agreement, component selection, and installation progress. These pages come with a default template and behavior that can be customized by editing the installer script.

The following are some of the most commonly customized installer pages:

• Introduction Page: This page is the first page that is displayed when the installer is launched. It includes the title and icon of the software and can be customized to include additional information about the software or the installation process.
• License Agreement Page: This page is displayed when the user needs to accept the licensing terms of the software. It can be customized with specific licensing terms or clauses that are relevant to the software.
• Component Selection Page: This page is used to select the components that will be installed. It can be customized with different layouts, images, and descriptions of each component.
• Installation Progress Page: This page displays the progress of the installation process. It can be customized with different progress bars, animation, and images to enhance the user experience.

Additionally, Qt installer framework provides us the ability to create custom installer pages that can be added to the installation process. These custom pages can be created using QML or C++ and can be used to provide additional functionality or information to the user during the installation process.

Customizing the installer pages is a great way to add some personality to the installer and enhance the overall user experience.

Conclusion

Customizing and configuring the installer is a crucial part of the development process. By using the configuration parameters and customizing the installer pages, we can create installers that are tailored to the specific needs of our software, which enhances the user experience and reduces support issues.

Qt installer framework provides us with a powerful toolset, and by using it to its fullest potential, we can create cross-platform installers that are both easy to use and visually appealing.

Building the Installer Package

Creating a graphical installer for your Qt applications can be a daunting task, but the Qt Installer Framework provides all the necessary tools to make the process as simple as possible. In this article, we will show you how to build an installer package step by step.

Before we begin, make sure you have installed the Qt Installer Framework on your system. You can download the latest version from the Qt website.

Step 1: Create the Installer Script

The first step in building an installer package is to create the installer script. This script contains all the information necessary to build the installer, including the list of files to install, the user interface of the installer, and the installation process itself.

The installer script is written in JavaScript, and can be created using any text editor. However, Qt provides a tool called the ‘IFW Wizard’ to help you create the script using a graphical interface. To use the IFW Wizard, simply open it and follow the instructions on the screen to create the script.

Once you have created the installer script, save it in a file named ‘installer.qs’.

Step 2: Prepare the Files to Install

The next step is to prepare the files to install. This includes all the necessary files and resources for your application, such as executable files, libraries, images, and documentation.

Create a directory named ‘packages’ in the same directory as the installer script. This directory will contain all the packages that will be installed by the installer.

Create a subdirectory inside ‘packages’ named after your application. This subdirectory will contain the files for your application.

Copy all the necessary files and resources for your application into the subdirectory. You can organize the files in any way you like, as long as they are all contained within the same directory.

Repeat this process for each package that will be installed by the installer.

Step 3: Create the Config File

The next step is to create the config file. This file contains all the information necessary to configure the installer, such as the destination directory, the installation components, and the licensing information.

Create a directory named ‘config’ in the same directory as the installer script. This directory will contain all the config files for the installer.

Create a file named ‘config.xml’ inside the ‘config’ directory. This file will contain the configuration information for the installer.

Open the ‘config.xml’ file in a text editor and fill in the necessary information. The Qt Installer Framework provides detailed documentation on how to configure the installer, including the available configuration options and their syntax.

Step 4: Build the Installer Package

The final step is to build the installer package. This is done using the ‘binarycreator’ tool, which is included with the Qt Installer Framework.

Open a terminal or command prompt and navigate to the directory containing the installer script.

Run the following command to build the installer package:

binarycreator --offline-only -c config/config.xml -p packages installer.exe

This command will create an offline installer named ‘installer.exe’, using the configuration information from the ‘config.xml’ file and the packages in the ‘packages’ directory.

You can customize the name of the output installer file by replacing ‘installer.exe’ with the desired filename.

Once the installer package is built, you can distribute it to your users and allow them to install your application with ease.

Building an installer package with the Qt Installer Framework may seem daunting at first, but with the provided tools and resources, the process becomes much more manageable. By following the steps outlined in this article, you can create a professional installer for your Qt applications in no time.
