Detailed Description

The QValueSpace namespace provides methods that are useful to Value Space layer implementors.

Value Space layers that are available at link time can be automatically installed using QVALUESPACE_AUTO_INSTALL_LAYER(name) macro. The method IValueSpaceLayer * name::instance() must exist and return a pointer to the layer to install. The QVALUESPACE_AUTO_INSTALL_LAYER(name) macro will only invoke this method after QApplication has been constructed, making it safe to use any Qt class in your layer's constructor.

Function Documentation

void QValueSpace::initValuespace ()

void QValueSpace::installLayer ( IValueSpaceLayer * layer )

Used by value space layer implementations to install themselves into the system. layer should be a pointer to the layer to install.
