Code Highlights
Loading Employees
The load_employees function retrieves all employee records from the database and populates the Treeview widget for selection.
def load_employees(): \"\"\"Load employees into the Treeview.\"\"\" tree.delete(*tree.get_children()) employees = session.query(Employee).all() for emp in employees: tree.insert("", "end", values=(emp.id, emp.name, emp.department, emp.basic_salary))Calculating Salary
The calculate_salary function computes salary details based on attendance records, basic salary, and additional components (HRA and DA).
def calculate_salary(): \"\"\"Calculate and display the salary details based on the selected employee and date.\"\"\" ...Refreshing Data
The refresh_data function updates employee and attendance data, ensuring that the latest records are used for payslip calculations.
def refresh_data(): \"\"\"Refresh all data including employees and attendance.\"\"\" ...Integration with the Main Page
The payslip_page function is integrated into the Payroll Management System. It is displayed under the Payslip Generation tab, allowing seamless access and interaction with the module.
