\title The Feature Definition File
|
|
|
|
By modifying the configured \c qconfig.h file from src/tools, you
|
|
can define a subset of the full Qt functionality that you wish to
|
|
be available in your installation. The -qconfig option to
|
|
configure is used to select the configuration.
|
|
|
|
Note that such modification is only supported on Qt/Embedded
|
|
platforms, where reducing the size of Qt is
|
|
important and the application set is often fixed.
|
|
|
|
The \c qconfig.h definition file simply defines macros to disable
|
|
features. Some features are dependent on other features and these
|
|
dependencies are expressed in \c qfeatures.h.
|
|
|
|
The available options are:
|
|
|
|
