Wt

It would be nice if we could bundle WDateEdit and WTimeEdit into one widget that uses WDateTime.

Natively, we can use an <input type="datetime-local">: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/datetime-local

For the non-native implementation, we could base it on a WLineEdit, just like WDateEdit and WTimeEdit, and popup something that allows changing both the date and time at the same time. We'll need some icon that expresses this. Font Awesome does not appear to include it, but there may be other similar royalty-free icons that we can use.

The WFormDelegate for WDateTime should be changed to use a WDateTimeEdit instead of a WLineEdit as well.
