Print SSH Information in the Ui Interfacebb

To print SSH output in a Qt UI interface, capture command output using libssh2 and utilize Qt's signal and slot mechanism. Create a signal in the FileTransfer class,
sshOutputReceived(QString output), and emit it after reading data from the remote file. Connect this signal to a slot in the MainWindow class to append the output to a QTextEdit widget, effectively displaying the SSH output in the UI.Tags

In order to print SSH output to a Qt UI interface, you can capture the output of the commands run through libssh2 and then use the Qt signal and slot mechanism to update the UI. In the context of the code provided above, let's assume we have a QTextEdit widget named
sshOutputTextEdit on our UI where we want to print the output.First, let's introduce a signal in the FileTransfer class that we'll emit whenever we get some output from the SSH command. We'll call this signal
sshOutputReceived(QString output).Then, in the
ssh_get_file function, after reading from the remote file, we emit this signal with the data we've just read.Now, in your UI code (presumably in your MainWindow class), you need to connect this signal to a slot that appends the text to the
sshOutputTextEdit.This way, whenever the
FileTransfer object reads some data from the remote file, it will emit a signal with this data, and the slot in the MainWindow will append this data to the sshOutputTextEdit. This will effectively print the SSH output to the Qt UI interface.Please note that you would need to replace some parts of this code with your actual implementation. These are only examples and may not work directly in your application without modifications. Also, don't forget to include the required header files for each class and function.
