class | Private |
Console prompt handler.
This class provides a convenient way to get user input in a secure way, as shown below:
QCA::ConsolePrompt::ConsolePrompt | ( | QObject * | parent = nullptr | ) |
Standard constructor.
parent | the parent object for this object |
void QCA::ConsolePrompt::getHidden | ( | const QString & | promptStr | ) |
Allow the user to enter data without it being echo'd to the terminal.
This is particularly useful for entry of passwords, passphrases and PINs.
promptStr | the prompt to display to the user |
void QCA::ConsolePrompt::getChar | ( | ) |
Obtain one character from the user.
void QCA::ConsolePrompt::waitForFinished | ( | ) |
Block waiting for user input.
You may wish to use the finished() signal to avoid blocking.
SecureArray QCA::ConsolePrompt::result | ( | ) | const |
Obtain the result of the user input.
This method is usually called to obtain data from the user that was requested by the getHidden() call.
QChar QCA::ConsolePrompt::resultChar | ( | ) | const |
Obtain the result of the user input.
This method is usually called to obtain data from the user that was requested by the getChar() call.
|
signal |
Emitted when the user input activity has been completed.
This corresponds to the provision of a string for getHidden() or a single character for getChar().
