Hitting F1 to see Qt's Help about a type is extremely useful. Thing is, it wont trigger unless the code is correct.

Stupid example:

• Your code does not #include <QMap>
• You know QMap has something interesting
• Type Qmap, hit F1, nothing is shown
• Fix it to QMap, hit F1, nothing is shown
  ...
• Get to google find it there

Is incorrect because QMap needs #include <QMap> first, but how could you know, you are requesting help to know about it.

Obviously there are more elaborated examples.

Solution:
Keep QtC aware of at least all Qt types to bring help.
