How to adjust QComboBox view max height?

[Tapsa]

The anemic 132 pixel default max height is too small. I want the height to vary between 0 and 400 pixels depending on the amount of items.

AComboBox::AComboBox(QWidget *papa, size_t length)
    : QComboBox(papa)
{
    setFixedWidth(length);
    view()->setMinimumWidth(ALineEdit::GIANT);
    view()->setMaximumHeight(400);
}

Above code has no effect and if I use min height instead then there is lots of blank space if too few items exist.
