Description Chris Burel 2010-08-31 02:39:47 UTC

QFlags<type> is a typedef for a uint, so, QFlags<type>& is a uint*.

smokedata.cpp for qtcore has a type for unsigned int&:
{ "unsigned int&", 0, Smoke::t_voidp|Smoke::tf_ref }

but all the QFlags<type>& are set to Smoke::t_uint :
{ "QFlags<QTextCodec::ConversionFlag>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QAbstractSpinBox::StepEnabledFlag>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QPaintEngine::DirtyFlag>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QPaintEngine::PaintEngineFeature>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyle::StateFlag>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyle::SubControl>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyleOptionButton::ButtonFeature>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyleOptionFrameV2::FrameFeature>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyleOptionTab::CornerWidget>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyleOptionToolBar::ToolBarFeature>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyleOptionToolButton::ToolButtonFeature>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<QStyleOptionViewItemV2::ViewItemFeature>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<Qt::AlignmentFlag>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<Qt::DropAction>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<Qt::KeyboardModifier>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<Qt::MouseButton>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<Qt::TouchPointState>&", 0, Smoke::t_uint|Smoke::tf_ref }
{ "QFlags<Qt::WindowType>&", 0, Smoke::t_uint|Smoke::tf_ref }

Those be set to Smoke::t_voidp.  In particular, the QFlags<QStyle*Option> ones break the usage of the QStyle*Option classes.

Reproducible: Always
Comment 1 Chris Burel 2010-09-02 19:18:13 UTC 
There's also a problem with the munged method name used for this.  If the argument is identified as 'unsigned int&', it gets a '$' in the signature.  But if it is identified as a 'QFlags<Type>&', it gets a '#'.  See QStyleOption::setState in QtGui for an example.
Comment 2 Arno Rehn 2010-09-02 20:41:08 UTC 
Ah, seems like this problem only occurs with fields. QStyleOption::state is actually a field with type QFlags<something>. The code for that is completely broken, as it seems.
Thanks for the report, I'll hopefully fix this over the weekend.
