fix #14257

[nyalldawson]

LGTM!

[vmora]

@nyalldawson the intent test works on my machine... any clue ? (I do compile with astyle option)

[nyalldawson]

Not sure why the test is passing locally, but I have a hunch it's only written for use on Travis. But the commit does have indentation issues - eg spacing around the brackets is wrong. So it's a valid failure ;)

[vmora]

Yes, you're right, fixed, hoping travis will give me the go.

[vmora]

because of a trailing white-space and a test that continues to pass on my machine...

@vmora Did you run scripts/prepare-commit.sh?
How about rebasing and squashing those indentation fix commits? Looks much nicer in the history then 😄

[m-kuhn]

I think this is a very common requirement. What do you think about adding a new QString QgsExpressionFieldWidget::asExpression() method?

[nyalldawson]

Thanks @vmora - I've manually pushed a version of this as d11e667 which incorporates @m-kuhn's suggestion so we don't miss 2.14
