Bug 310450

The KDE HIG on form label alignment [1] recommends to right-align labels next to their "buddy" input fields. Historically, a QGridLayout was chosen in such cases, which makes the label left-aligned. An example is the composer window of KMail, where labels for "To" or "Subject" are aligned left along the left window border and thus have a varying spacing to their line edits on the right.
The modern approach is to use a QFormLayout, which depending on the platform (KDE, Gnome, Windows, Mac) chooses the right label alignment.
In cases where a QFormLayout is not a viable option and a QGridLayout has to be kept in use, labels can be aligned using a call like
label->setAlignment((Qt::Alignment)label->style()->styleHint(QStyle::SH_FormLayoutLabelAlignment));

This bug report makes a fine Junior Job, as the necessary changes are local and can be done by new programmers without application-specific knowledge (in most cases). I would assume that this bug report will stay "work in progress" indefinitely as there will be always applications which do not follow the HIG.

Furthermore, it may be argued that this specific label alignment problem is only a minor UX issue, but it is still a problem and if we want to take our own HIG serious, we should do something about this.
