Notes to developers: what KAboutData::setApplicationData() is

[Jaroslaw Staniek]

Hi
If you look at apps ported to KF5, KAboutData::setApplicationData() is
used but there are also redundant lines in main(), at least these:

app.setApplicationName(aboutData.componentName());
app.setApplicationDisplayName(aboutData.displayName());
app.setOrganizationDomain(aboutData.organizationDomain());
app.setApplicationVersion(aboutData.version());

Note, this is already performed by KAboutData::setApplicationData().

For example Kate --
http://lxr.kde.org/source/kde/applications/kate/kate/src/main.cpp

For the list see
http://lxr.kde.org/search?_filestring=&_string=setApplicationDisplayName

Sometimes there are even deeper duplication of names, e.g. despite of
using KAboutData there's also:

QApplication::setApplicationName("kanagram");

-- http://lxr.kde.org/source/kde/applications/kate/kate/src/main.cpp

If I am right, this is a note for developers to fix that -- KAboutData
was designed to make main() easier but actually main() looks
unnecessary complicated for a number of KDE apps. Looks like people
take another app's code as a template and copy it :)

No idea if more general improvement could be an addition to the
apidocs of a crazy check.
