| 36 | <p> By modifying the configured <tt>qconfig.h</tt> file from src/tools, you
|
|---|
| 37 | can define a subset of the full Qt functionality that you wish to
|
|---|
| 38 | be available in your installation. The -qconfig option to
|
|---|
| 39 | configure is used to select the configuration.
|
|---|
| 40 | <p> Note that such modification is only supported on Qt/Embedded
|
|---|
| 41 | platforms, where reducing the size of Qt is
|
|---|
| 42 | important and the application set is often fixed.
|
|---|
| 43 | <p> The <tt>qconfig.h</tt> definition file simply defines macros to disable
|
|---|
| 44 | features. Some features are dependent on other features and these
|
|---|
| 45 | dependencies are expressed in <tt>qfeatures.h</tt>.
