What is QSS file?

How to open QSS file?

An often recurring problem with Qt Style Sheet is that QSS is not associated with the correct program file. Thus, when you open QSS, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the QSS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Nokia Qt Creator

In this case, you should first verify that the Nokia Qt Creator application is installed on the computer. To do this, enter the name Nokia Qt Creator into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file QSS.

Programs to open QSS file

Remember to download programs supporting QSS files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Nokia Qt Creator with QSS files

However, it may happen that the application itself does not cause the QSS file to open in the Nokia Qt Creator application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Nokia Qt Creator application as the default for handling the QSS file.

Step 3. Update Nokia Qt Creator to the latest version

The fault may also lie with the Nokia Qt Creator program, it is possible that Qt Style Sheet requires a newer version of the program.

Step 4. Check for the following problems with the QSS file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the QSS file. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file QSS or the program directory. However, remember that not every infected QSS file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the QSS files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair QSS file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted QSS files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the QSS file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file QSS to close. However, some background programs may block the QSS file while scanning. If the problem persists, restart the machine.
