    Hi. I have been trying to display date in the database into to datedit widget on UI form. But the date is not showing up. I am using sqlite database, and the datatype I have specified for it is "datetime". Below is the code I have written, where the date in database is pulled up successfully and display in "lineedit", but it doesnt show up if I use "dateedit" widget.

    @
    qry2->prepare("select date_of_birth from member where id="A1" or name="Ram"");
    QString d = qry2->value(0).toString();
    ui->lineEdit->setText(d);
    @

    Can you please tell me the code for displaying data in "dateedit" widget?

    Edit: Added code tags '@@' - p3c0

        Also, I am trying to use checkboxes and radiobuttons. I can read the data from these and write some values into the database. But when I try to do the reverse, that is to read data back and accordingly check the radiobuttons I can do it.
        @
        if((string == "male"))
        {
        ui->radioButton_male->setChecked(1);
        }
        else
        ui->radioButton_female->setChecked(1);
        @

        But the same is not happening in case of check boxes.

        @
        if(string == "male")
        {
        ui->checkBox_yoga->setChecked(1);
        }
        @

            Hi,

            bq. Can you please tell me the code for displaying data in “dateedit” widget?

            QDateEdit expects QDate. So convert the output string to QDate and the set using "setDate":http://qt-project.org/doc/qt-5/qdatetimeedit.html#date-prop

            Please Rephrase the 2nd question. It's bit confusing to understand.

                Thank you for the reply on QDate.
                Second question: My code accepts the value from radio-buttons and stores respective string values in database. And now I have another part of code, which reads the previously stored value and ticks the respective radio button. For this operation, the code I wrote is,

                @
                if((string == "male"))
                {
                ui->radioButton_male->setChecked(1);
                }
                else
                ui->radioButton_female->setChecked(1);
                @

                Similar to radiobuttons, I want to use checkboxes. That is to read values from the database and check mark the respective checkboxes. The code for this I wrote is as below, but it is not checking though the query fetches the data.

                @
                if(string == "male")
                {
                ui->checkBox_male->setChecked(1);
                }
                else
                {
                ui->checkBox_female->setChecked(1);
                }
                @

                    Please use code tags '@@' to post code.
                    Try using boolean values instead of integer. But that shouldn't matter actually. I guess there should be some other problem.

                        Yes, I tried using boolean values too, problem still persists.
                        Thanks for the effort.

                            Can you post other parts of the code in relevance to this problem ?

                                I am sorry for the partial code. Below is my actual code.

                                @login_page conn;
                                QString fill = ui->tableView->model()->data(index).toString();

                                if(!conn.connopen())
                                {
                                qDebug()<<"Not connected";
                                return;
                                }

                                conn.connopen();
                                QSqlQuery * qry = new QSqlQuery();
                                QSqlQuery * qry1 = new QSqlQuery();
                                QSqlQuery * qry2 = new QSqlQuery();
                                QSqlQuery * qry3 = new QSqlQuery();
                                qry->prepare("select * from instructor where i_id='"+fill+"' or i_name='"+fill+"'");

                                  I am sorry for the partial code. Below is my actual code.

                                  @login_page conn;
                                  QString fill = ui->tableView->model()->data(index).toString();

                                  if(!conn.connopen())
                                  {
                                  qDebug()<<"Not connected";
                                  return;
                                  }

                                  conn.connopen();
                                  QSqlQuery * qry = new QSqlQuery();

                                    Sorry but the code looks little bit weird. I think you must first rectify them:

                                    1. No need to open the database twice.
                                    2. Since you are fetching everything from the same table with same where clauses why unnecessarily complicate the code by firing 4 different queries.
                                    3. Furthermore it complicates the if and while conditions.
                                    4. Closing the connection in while loop would be a bad idea as it will close the database and the end of first iteration itself and thus affecting the remaining data if any.
