Could somebody help me, i have 2 classes, Calendar.cpp and Appointment.cpp
The Appointment class works like it should be able to make a new appointment.
When I click a menu in the calendar class, a new dialogue-window should appear that adds the appointment.
How should i connect what i write in the Appointment dialogue to the Calendar class as an appointment. I cant figure out how to get the text updated correctly between the 2 classes.
