Subject: Qt4: do not create pref tooltip if there is no text
X-Git-Tag: 1.2.0-pre1~5346
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=d45fa422b40406ae66512d14d3d44517708f13fb;p=vlc

Qt4: do not create pref tooltip if there is no text

By the way, it seems like we should always use NULL rather than "" for
longtext. Not only this avoids the recurrent gettext("") translation
problem, but an empty tool tip makes no sense. There should be no tool
tip at all if there is no text.
