[QGIS-Developer] Drag and drop form function QdateEdit Widget init

[PIERRE Sylvain]

Hi Andeas,

Good tip !
I have to keep init script for good reason ;-). But I was not aware (not enough yet) of such possibilities. So for setting current date it’s pretty cool.
QGIS will still be amazing !

Thanks again

Hi Pierre,

Not sure if you are aware that recent QGIS releases also have very good "default" value support without having to use Python. You can simply set default values with QGIS expressions. No need for Python code (unless you do something really special).

You can even set date values dependent on other widgets without having to use Python scripting - and do updates whenever something changes on the record, without having to fall back to Python scripting.

Just wanted to make sure you are aware of this alternative mechanism. There might still be good reasons for using Python scripting though - but theses cases are now rarer.

Greetings,

Andreas

QgsDateTimeEdit implements setDateTime, which is not virtual in QDateTimeEdit.
It's probably that you have to find a QDateTimeEdit rather than the Qt native one.

Not 100% sure this is the issue though, but it won't hurt.

Thanks for tip Richard, but I've tried with
            today = QtCore.QDateTime.currentDateTime()
But it's not working

Hi,

Which module is 'date.today()' from, not Qt is it?

You probably have to use the QDatetime: https://doc.qt.io/qt-5/qdatetime.html#currentDateTime

>>> QDateTime.currentDateTime()
PyQt5.QtCore.QDateTime(2022, 3, 25, 8, 44, 19, 963)

And set THAT with the widget?

See: https://doc.qt.io/qt-5/qdatetimeedit.html#dateTime-prop

(it always a little hassle to juggle with date/time etc in Python/Qt)

Regards,

Richard Duivenvoorde
