    That is not what I want. I did pass the QTime and got that too.
    I want the default time to change to what the user types in the TimeEdit field.
    For instance, if he changes it to 1:30 pm when he clicks "accept" then the a message box pops up and shows " 1:30 pm"
    Is this possible ?

    Here calandertime.cpp

    Qt Code: 
    1. #include "calendartime.h"
    2. #include<QtGui>
    3. #include<Qtime>
    4. #include<QMessageBox>

    6.  
    7.  
    8. calendartime::calendartime(QWidget *parent) :
    9.     QDialog(parent)
    10.  
    11. {
    12.  
    13.    setupUi(this);
    14.  
    15. this->resize(355, 180);
    16. secondaryGroupBox->hide();
    17. connect(moreButton, SIGNAL(clicked(bool)),this , SLOT(display_time(bool)));
    18. connect(acceptButton, SIGNAL(clicked(bool)),this , SLOT(display_message()));
    19.  
    20. }
    21.  
    22. calendartime::~calendartime()
    23. {
    24.     delete this;
    25. }
    26.  
    27.  
    28. void calendartime::display_time(bool)
    29. {

    31. this->resize(355,273);
    32. secondaryGroupBox->show();
    33.  
    34.  
    35. }

    41.     QString timeInString = timeEdit.toString("h:m:s ap");

    Yes, it's possible, but you are creating a QTimeEdit object in your display_message method, and so the time there will always be 12:00 and not be editable. You need to use the object in the ui namespace.

    92. QT_END_NAMESPACE
    93.  
    94. #endif // UI_CALENDARTIME_H
    To copy to clipboard, switch view to plain text mode 

    Here is the modified display_message method:
    Qt Code: 
    1. void calendartime:: display_message()
    2. {
    3.   QMessageBox msgbox;
    4.     QTimeEdit timeEdit;
    5.  
    6.     QString timeInString = timeEdit.time().toString("h:m:s ap");
    7.       msgbox.setText(timeEdit.text());
    8.       msgbox.exec();
    9. }
    To copy to clipboard, switch view to plain text mode 

    it stil displays the default time. arrgh

    But You have again and again local variable timeEdit. In class Ui_calendartime You have public variable timeEdit and this is what You want. Yours display_message method must look like this :
    Qt Code: 
    1. void calendartime:: display_message()
    2. {
    3.   QMessageBox msgbox;
    4.  
    5.     QString timeInString = timeEdit->time().toString("h:m:s ap");
    6.       msgbox.setText(timeEdit.text());
    7.       msgbox.exec();
    8. }
    To copy to clipboard, switch view to plain text mode 

    Sorry for my comment but they are bases of C++ (range of variables).
