Public Member Functions

 SchemeManager (void)
 Constructor for SchemeManager objects.
 ~SchemeManager (void)
 Destructor for SchemeManager objects.
SchemeloadScheme (const String &scheme_filename, const String &resourceGroup="")
 Loads a scheme.
void unloadScheme (const String &scheme_name)
 Unloads all data referenced in a scheme. If any object is using some resource which is listed in the scheme, this function will effectively pull the rug out from under those objects. This should be used with extreme caution, or not at all.
bool isSchemePresent (const String &scheme_name) const
 Returns true if the named Scheme is present in the system (though the resources for the scheme may or may not be loaded).
SchemegetScheme (const String &name) const
 Returns a pointer to the Scheme object with the specified name.
void unloadAllSchemes (void)
 Unload all schemes currently defined within the system.
SchemeIterator getIterator (void) const
 Return a SchemeManager::SchemeIterator object to iterate over the available schemes.


Detailed Description

A class that manages the creation of, access to, and destruction of GUI Scheme objects.

Member Function Documentation

Scheme * CEGUI::SchemeManager::getScheme ( const String name  )  const

Returns a pointer to the Scheme object with the specified name.

Parameters:
name String object holding the name of the Scheme to be returned.
Returns:
Pointer to the Scheme named name.
Exceptions:
UnknownObjectException thrown if no Scheme named name is present in the system

bool CEGUI::SchemeManager::isSchemePresent ( const String scheme_name  )  const [inline]

Returns true if the named Scheme is present in the system (though the resources for the scheme may or may not be loaded).

Parameters:
scheme_name String object specifying the name of the Scheme to check for.
Returns:
true if the scheme is loaded, false if it is not.

Scheme * CEGUI::SchemeManager::loadScheme ( const String scheme_filename,
const String resourceGroup = "" 
)

Loads a scheme.

Parameters:
scheme_filename String object that holds the filename of the scheme to be loaded
resourceGroup Resource group identifier to be passed to the resource manager. NB: This affects loading of the scheme xml file only, scheme resources may specify their own groups.
Returns:
Pointer to an object representing the loaded Scheme.

void CEGUI::SchemeManager::unloadAllSchemes ( void   ) 

Unload all schemes currently defined within the system.

Note:
Calling this method has the potential to be very dangerous; if any of the data that forms part of the scheme is still in use, you can expect fireworks shortly after!
Returns:
Nothing.

void CEGUI::SchemeManager::unloadScheme ( const String scheme_name  ) 

Unloads all data referenced in a scheme. If any object is using some resource which is listed in the scheme, this function will effectively pull the rug out from under those objects. This should be used with extreme caution, or not at all.

Parameters:
scheme_name String object specifying the name of the Scheme to be unloaded.
