QCalendarWidget as "Pop-up", not as new Window?

Question

Hi there.

I want to create a Settings-Widget, where I can choose a Date.
Because it isn't nice to create 3 QLineEdits to call the QDate-Constructor with QDate(int year, int month, int day), I thought it would be better, if you can push a "show calendar"-Button for example, where you can choose the date.
But I don't want to show this calendar in a new Window, I want to show it as a "Pop-up" (I don't know how to explain this), which you might know for example from the OpenOffice-Settings.
You have any idea how to implement that?

Answer 1

This is an example of a type popup calendar, you must display the calendar when you press the button on the form. This class can be reutilized in anywhere in your code. In this example this is launched in main function.

    int result = popup.exec();
    if(result == QDialog::Accepted){
        QDate date = popup.selectedDate();
        std::cout<< date.year() <<std::endl;
        std::cout<< date.month() <<std::endl;
        std::cout<< date.day() <<std::endl;

    return a.exec();

For an alternate option, have you considered using QDateEdit? It will allow your users to edit the date in a format that is consistent with the rest of the operating system.
