<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">this is inefficient. rewrite this such that you merge the startsWith into the getAbbrevation call, i.e.:
if (abbrevationMatches(m_nameColumn, match)) {
matchCompletion = AbbrevationMatch;
}
Note: Don't pass m_nameColumn.toLower() as that would need a alloc which is costly. Instead, use QChar comparison and it's ::toLower() method which does not need malloc.
Furthermore, this way you only need to go up to the first part of m_name where it's abbreviation deviates from the match.
I.e.:
m_name = fooBarAsdfLaLaLa
match= fXYZ
your code would need to convert fXYZ to fxyz. Then it iterates over all of m_name and allocates a string holding "fBALLL". Then it does the comparison.
Instead I want no allocs, and only iterate up to, including, fooB of m_name. At that point you can already say that there is no match.</pre>

This patch implements less restrictive rules for completion list filtering. Currently, an item is only displayed if it starts with the typed text. In addition to that, I'd like to allow:
1) Abbreviation expansion; see first screnshot. This matches entries where the entered text matches the (beginning of) the camelCased or under_scored entry name's first letters.
2) Match if the entry only contains the word. This probably needs a bit of thinking to not disrupt existing workflows. My current solution only uses this filter if the length of the entered text is 4 or more characters.
What do you think?
Do you think this should be configurable?</pre>
