How to take input date from user in qdateedit and show database accordingly
-
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. -

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

Sorry but the code looks little bit weird. I think you must first rectify them:
- No need to open the database twice.
- Since you are fetching everything from the same table with same where clauses why unnecessarily complicate the code by firing 4 different queries.
- Furthermore it complicates the if and while conditions.
- 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.
