To transfer a file to a remote computer using the SSH protocol in Qt, you can utilize the QProcess class to execute the scp command line tool. Here's a sample code that demonstrates how to achieve this:
In this code, you need to replace the localFilePath and remoteFilePath variables with the appropriate file paths. The localFilePath represents the path of the file on the local computer, and the remoteFilePath represents the SSH connection string and the path of the file on the remote computer.
The code uses QProcess to execute the scp command with the specified local and remote file paths as arguments. The process is then started using process.start() and the execution is blocked until the process finishes using process.waitForFinished().
After the process has finished, the exit code is checked to determine if the file was transferred successfully or if there was an error.
Make sure to have the necessary SSH tools, such as scp, installed and accessible in your system's command line environment.
Note: This example assumes that you have proper SSH access and authentication set up for the remote computer. Additionally, it's important to handle any potential errors and handle edge cases according to your specific requirements.
