Problem with QtDateTime

[nanohueso]

Hi, im using the Date/Time Edit widget. I want that the widget to start (default date/time) from the current date time of my region ( Buenos Aires) , and i want to modify it and then extract the datetime in to a string , in order to have something like this buffer[15] , where the buffer is composed in something like this

buffer[0] = YEAR
buffer[1] = YEAR
buffer[2]='/'
buffer[3] = month
buffer[4]=month
buffer[5]='/'
buffer[6]=day
buffer[7]=day
buffer[8]=hour
buffer[9]=hour
buffer[10]=':'
buffer[11]=mins
buffer[12]=mins
buffer[13]='P' or 'A'
buffer[14]='M
buffer(15]='\o'

¿How can i make that when i run thee program , the widget starts for the current date time ?
¿How can i put in a string the date-time configurated from the widget ?

QDateTime aux;
QString auxstr;
ui->dateTimeEdit_inicial->setDateTime(aux.currentDateTime()); // where do i have to put this code ? in which function?
note: dateTimeEdit_inicial is the object name of the widget
then, i have to find someway to pass the information from the widget to the aux ( aux is a QDateTime variable) because then i use aux.toString(auxstr); and then i have the string completed :)
Also, i need to resize the QString auxstr in order to be capable of containing the whole array of characters , i have to use the member function resize : auxstr.resize( WHAT DO I HAVE TO PUT IN HERE ?? ) ;

I think thats all .
Thank you for your time!!

probably somewhere in the constructor of your class where you setup "ui". But IIRC QDateTime should have the current time by default?

just use QDateTime::toString(formatString) and you are good to go.

No you don't need to do that. Just assign it with "=" and let Qt do the rest for you ;)
