QDateTimeEdit

[coderbob]

When sub classing QLineEdit I can use functions such as hasSelectedText(), isUndoAvailable() to re implement copy,undo, etc functions for a contextMenuEvent.

Sub classing QDateTimeEdit I can not find any of these functions or something I can re implement from an inherited object.

QDateTimeEdit does have these functions in its default context menu so I am not sure where I am missing the connection.

You are not missing anything. QDateTimeEdit does not inherit QLineEdit. Therefore the mentioned methods are not available.

But it still offers such features as copy,paste,etc from its context menu. So my guess is it implements the functionality somewhere?

I would suppose so. It inherits QAbstractSpinBox which in turn inherits Qwidget. Both show some events. Probably the best place to look at is the source code of QDateTimeEdit.
