Currently, Qt always stores the data directly in the executable, even on Windows and Mac OS X, where the operating system provides native support for resources. This might change in a future Qt release.

Resources are compressed by default in the ZIP format. It is possible to turn off compression. This can be useful if your resources already contain a compressed format, such as. You do this by giving the -no-compress command line argument. The tree is automatically built at startup and used by QFile for resolving paths to resources. Qt's resources support the concept of a search path list. The search path list is empty at startup; call QDir::addSearchPath to add paths to it.

This ensures that the resources are linked into the final application binary in the case of static linking. You should put the initialization code close to where the resources are used in your library, so that clients of your library will only link in the resources if they use the feature of the library that depends on them. If the library includes resources that are not used internally, but instead exposed to clients of the library, the initialization needs to happen in the application code.

As before, this ensures that the resources are linked into the final application binary in the case of static linking, but also triggers loading of the library in the case of dynamic linking, such as plugins.

In order to be able to add icons using the Qt Resource system from within Qt Creator you need to have an active Qt Project, and add both your UI and resource files to it.

If you don't have a Qt Creator project set up you can create one in your existing source folder. Qt Creator will prompt before overwriting any of your files. Select the folder above your source folder for "Create in", and provide the name of your source folder as the project name. You can delete any files created, except the.

The screenshot below shows the Designer with our counter app open, and the increment button selected. The icon for the button can be chosen by clicking the small black down arrow and selecting "Choose Resource…".

The Resource chooser window that appears allows you to pick icons from the resource file s in the project to use in your UI.
