Bug ID: 468419
Summary: Add a check that discourages isNull (in favor of
isEmpty)
Classification: Developer tools
Product: clazy
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: dange...@gmail.com
CC: smart...@kde.org
Target Milestone: ---
Qt string-like classes feature two similar but different functions: isNull and
isEmpty. There are differences between the two, and the differences are subtle;
a null string is always empty but an empty string isn't necessarily null (e.g.
QString("") is empty but not null). Usage of isNull is almost always
questionable.
(One could also extend this to other classes, e.g. QRect, where the null vs.
empty semantics are very weird.)
