Autocomplete does not offer local or member variables in method calls

Autocomplete does not work when filling out parameters for method calls - at least local variables and class fields are not offered. Mostly, no autocomplete list is displayed at all.

Steps to repeat:

• Open "BasicDrawing" sample
• Go to RenderArea::paintEvent and append an empty line at the end of the method
• Try coding the following line using autocomplete for all symbols on the way. Type slowly.
  QPixmap myPixmap(pixmap);
  QPixmap is mostly autocomplete supported (if you don't type too fast). However, after opening the bracket after "myPixmap", the class member "pixmap" is not offered.
• Alternatively, try coding
  QPixmap myPixmap(painter.clipBoundingRect().size().toSize());
  Again, QPixmap is recognized, but painter is not. After typing "painter." the methods are offered again.
• Alternatively, try coding
  QPixmap myPixmap;
  QPixmap myPixmap; myPixmap.fill(painter.brush().color());
  When typing ".fill(pa" the symbol "painter" is not offered.
