time and date issues

this question probanly has more to do with my lack of knowledge than anything else, but the lack is real!
, I work for a railroad as a conductor and have been trying to produce a program thta will handle time card submittals in a complex work rule environment.

The problem is working with time calculations. Am I wasting my time tryng to use the time edit functons in QT since I don't know how to access the elements of the widgets ,or should I just set up fields for the user to enter hours and minutes. i.e , no spin boxes

There are widgets like QTimeEdit, QDateEdit and QDateTimeEdit which you can use for all your time and date related inputs and then you can do all your calculations.

The time and date spinboxes will QDate, QTime and QDateTime classes you can access. These will give you all the time information you need.

i have a doubt..pls help..

i have 2 QDateEdits..ie one s start_date and other is end_date..i want to find difference between them and display in a QLineEdit..how to do it?

i did
int s=ui->start_date.day();
int e=ui->end_date.day();
int diff=e-s; //this works correctly it returns the difference
Qstring d=diff.toString(); //here am getting junk values y?

ui->line_edit->setText(d);

try daysTo() function.
Ex:

Code:

---

QDate date1;
QDate date2;
int nDiff = date1.daysTo(date2);
ui->line_edit->setText(QString::number(nDiff));

---

Quote:

---

Qstring d=diff.toString(); //here am getting junk values y?

---

you need to convert the int to string ().


hope it helps

I'm really surprised how your compiler built this line

Code:

---

...
int diff=e-s;
Qstring d=diff.toString(); //<----
...
