[Qgis-user] qt designer does not have/show QgsDateEdit widget

[Janneke van Dijk]

Hi Richard and Andrea (and others),

thanks for clarifying/confirming - then it is not something I
misunderstood. I originally had the QDateEdit widget, which was working,
but giving a warning that it will not accept NULL values. As I would like
to be able to set it to NULL I thought of using QgsDateEdit. I have now
indeed managed to instead format the QgsDateTimeEdit widget to only show
the date, which will do for my purpose.

I am now trying to adjust the code that was working for QDateEdit to work
for the QgsDateTimeEdit with the following function that gets called
clicking a button. The first message will display the time and date
correctly, so 'now' seems to have the correct value. The second message
does not get displayed, but I also do not get an error message, and the
date does not get changed. Which makes me believe
"self.assesmentdate.setDateTime(now)" is not correct.

    def assesmentdate_now(self):
        if self and self.layer.isEditable():
            now = QtCore.QDateTime.currentDateTime()
            QgsMessageLog.logMessage(now.toString(), 'MyPlugin',
level=Qgis.Info)
            self.assesmentdate.setDateTime(now)
            QgsMessageLog.logMessage('test', 'MyPlugin', level=Qgis.Info)


What would be the correct syntax for setting the QgsDateTimeEdit widget to
show the current date?  Or does anyone have ideas how I can find out what's
happening, seeing that I am not getting error messages? The script gets
called by the attribute form.

Thanks for any thoughts,
Janneke
