Converting Date Format

[Vineela]

Converting QString date format from "yyyy-MM-dd" to "dd-MM-yyyy"

this is my QString
QString dd = "2018-08-01";

QDate da=QDate::fromString(dd,"dd-MM-yyyy");
well this line gives error saying "QDate(Invalid)"
so how can i change my format???

                     QDate da=QDate::fromString(dd,"yyyy-MM-dd");
                     QString dw = da.toString("dd-MM-yyyy");

@Vineela said in Converting Date Format:

QDate da=QDate::fromString(dd,"dd-MM-yyyy");

Shouldn't it be

QDate da=QDate::fromString(dd,"yyyy-MM-dd");

?
Your string is "2018-08-01" and not "01-08-2018"...

[VRonin]

fromString wants the format you are converting from ,not to
QDate da=QDate::fromString(dd,Qt::ISODate); (yyyy-MM-dd is the ISO-8601 format)

@jsulm oh yes that was so silly thanks but my output now is 01/08/18 this ,what abt last one yyyy ?

@Vineela You can convert your date to whatever string you want.

@Vineela
As @jsulm has just stated, you now have an issue about your date output format not the input you converted from. Look through the documentation of http://doc.qt.io/qt-5/qdate.html#toString, i.e. toString() not fromString().

                     QDate da=QDate::fromString(dd,"yyyy-MM-dd");
                     QString dw = da.toString("dd-MM-yyyy");
