Question 1 Write an application that can be used to process Staff member
details. The fields that should be stored include: • A name, • A birthdate, and •
,A staff appointment type (one of permanent, part-time, or contract, stored as
an enum). Note that the getter and setter for this data member may be done
using a QString. Downloaded by Corona Virus () lOMoARcPSD| The
application should allow a user to enter details via GUI. Also, once a staff
member’s details are entered, they should be written to file (in any acceptable
format) and stored in a container in the application. Ensure that you adhere to
basic design principles, and avoid any anti-patterns in the design of your
solution.
To create an application for processing Staff member details with the specified requirements
(GUI input, file storage, enum usage), we'll follow a structured approach using C++ and Qt
framework for the GUI part. Here’s a step-by-step outline of how you can implement this:
Step-by-Step Implementation
1. Define the Staff Member Class
First, define a class StaffMember to encapsulate the details of each staff member. This class will
have:
name (QString)
birthdate (QString for simplicity, but ideally, you might use QDate or QDateTime for
better date handling)
appointmentType (enum class)
cpp
Copy code
#include <QString>
// Enum for appointment types
enum class AppointmentType {
Permanent,
PartTime,
Contract
};
class StaffMember {
public:
StaffMember() {}
QString getName() const { return name; }
void setName(const QString &value) { name = value; }
QString getBirthdate() const { return birthdate; }
void setBirthdate(const QString &value) { birthdate = value; }
AppointmentType getAppointmentType() const { return appointmentType; }
void setAppointmentType(AppointmentType value) { appointmentType =
value; }
, private:
QString name;
QString birthdate;
AppointmentType appointmentType;
};
2. GUI Implementation using Qt
For the GUI, create a Qt application with a form that allows users to input staff member details
and save them. Here’s a basic outline of the main window form (mainwindow.ui) using Qt
Designer:
Labels: Name, Birthdate, Appointment Type
Line Edits: Input fields for Name and Birthdate
Combo Box: For selecting Appointment Type (with options: Permanent, Part-time,
Contract)
Buttons: Save button to save the details entered
3. Implement MainWindow Class
In your MainWindow class (derived from QMainWindow), handle the GUI interactions and file
operations. Here’s a simplified version:
cpp
Copy code
#include <QMainWindow>
#include <QFile>
#include <QTextStream>
#include <QMessageBox>
#include "staffmember.h" // Include your StaffMember class
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = nullptr);
~MainWindow();
private slots:
void onSaveButtonClicked();
private:
Ui::MainWindow *ui;
QList<StaffMember> staffMembers;
void saveToFile(const QString &fileName);
};
