UPDATE :: Choosing -- Senator force tag refresh inside the proper include helped ...

Why I do have to do that manually ?

CEDET  semantic pop up menu cannot complete this properly : "Ogre::ResourceGroupManager::D"

that is to

DEFAULT_RESOURCE_GROUP_NAME;
I use CEDET 1.1 from repo , turned all possible semantics modes ;

 

I know about this issue :

>>>

For example, some libraries use preprocessor symbols in class definitions, like

class SOMESYMBOL someClass {
....
};

where SOMESYMBOL is often expanded to some gcc attribute or similar. If SOMESYMBOL is defined in some other header file, Semantic will not be able to parse this. The reason for this is that Semantic does not parse every #define’d symbol out there - this would simply make parsing too slow. The easiest way to deal with this problem is to simply give Semantic a definition for SOMESYMBOL:

(add-to-list 'semantic-lex-c-preprocessor-symbol-map '("SOMESYMBOL" . ""))


So I added (add-to-list 'semantic-lex-c-preprocessor-symbol-map '("_OgreExport" . "")) because of the class

But still nothing . Below, I add the troublesome include :

@par
Defining new resource groups, and declaring the resources you intend to

if a ResourceManager supports the definition of resources through scripts,
then this is the class which drives the locating of the scripts and telling
the ResourceManager to parse them.
@par
There are several states that a resource can be in (the concept, not the
object instance in this case):
<ol>
<li><b>Undefined</b>. Nobody knows about this resource yet. It might be
in the filesystem, but Ogre is oblivious to it at the moment - there
is no Resource instance. This might be because it's never been declared
(either in a script, or using ResourceGroupManager::declareResource), or
it may have previously been a valid Resource instance but has been
removed, either individually through ResourceManager::remove or as a group
through ResourceGroupManager::clearResourceGroup.</li>
<li><b>Declared</b>. Ogre has some forewarning of this resource, either
through calling ResourceGroupManager::declareResource, or by declaring
the resource in a script file which is on one of the resource locations
which has been defined for a group. There is still no instance of Resource,
but Ogre will know to create this resource when
ResourceGroupManager::initialiseResourceGroup is called (which is automatic
if you declare the resource group before Root::initialise).</li>
<li><b>Unloaded</b>. There is now a Resource instance for this resource,
although it is not loaded. This means that code which looks for this
named resource will find it, but the Resource is not using a lot of memory
because it is in an unloaded state. A Resource can get into this state
by having just been created by ResourceGroupManager::initialiseResourceGroup
(either from a script, or from a call to declareResource), by
being created directly from code (ResourceManager::create), or it may
have previously been loaded and has been unloaded, either individually
through Resource::unload, or as a group through ResourceGroupManager::unloadResourceGroup.</li>
<li><b>Loaded</b>The Resource instance is fully loaded. This may have
happened implicitly because something used it, or it may have been
loaded as part of a group.</li>

/** Create a resource group.
@remarks
A resource group allows you to define a set of resources that can
be loaded / unloaded as a unit. For example, it might be all the
resources used for the level of a game. There is always one predefined
resource group called ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME,
which is typically used to hold all resources which do not need to
be unloaded until shutdown. There is another predefined resource
group called ResourceGroupManager::INTERNAL_RESOURCE_GROUP_NAME too,
which should be used by OGRE internal only, the resources created
in this group aren't supposed to modify, unload or remove by user.
You can create additional ones so that you can control the life of
your resources in whichever way you wish.
There is one other predefined value,
ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME; using this
causes the group name to be derived at load time by searching for
the resource in the resource locations of each group in turn.
@par
Once you have defined a resource group, resources which will be loaded
as part of it are defined in one of 3 ways:
<ol>
<li>Manually through declareResource(); this is useful for scripted
declarations since it is entirely generalised, and does not
create Resource instances right away</li>
<li>Through the use of scripts; some ResourceManager subtypes have
script formats (e.g. .material, .overlay) which can be used
to declare resources</li>
<li>By calling ResourceManager::create to create a resource manually.
This resource will go on the list for it's group and will be loaded
and unloaded with that group</li>
</ol>
You must remember to call initialiseResourceGroup if you intend to use
the first 2 types.
@param name The name to give the resource group.
@param inGlobalPool if true the resource will be loaded even a different
group was requested in the load method as a parameter.
*/
void createResourceGroup(const String& name, const bool inGlobalPool = true);


/** Initialises a resource group.
@remarks
After creating a resource group, adding some resource locations, and
perhaps pre-declaring some resources using declareResource(), but
before you need to use the resources in the group, you
should call this method to initialise the group. By calling this,
you are triggering the following processes:
<ol>
<li>Scripts for all resource types which support scripting are
parsed from the resource locations, and resources within them are
created (but not loaded yet).</li>
<li>Creates all the resources which have just pre-declared using
declareResource (again, these are not loaded yet)</li>
</ol>
So what this essentially does is create a bunch of unloaded Resource entries
in the respective ResourceManagers based on scripts, and resources
you've pre-declared. That means that code looking for these resources
will find them, but they won't be taking up much memory yet, until
they are either used, or they are loaded in bulk using loadResourceGroup.
Loading the resource group in bulk is entirely optional, but has the
advantage of coming with progress reporting as resources are loaded.
@par
Failure to call this method means that loadResourceGroup will do
nothing, and any resources you define in scripts will not be found.
Similarly, once you have called this method you won't be able to
pick up any new scripts or pre-declared resources, unless you
call clearResourceGroup, set up declared resources, and call this
method again.
@note
When you call Root::initialise, all resource groups that have already been
created are automatically initialised too. Therefore you do not need to
call this method for groups you define and set up before you call
Root::initialise. However, since one of the most useful features of
resource groups is to set them up after the main system initialisation
has occurred (e.g. a group per game level), you must remember to call this
method for the groups you create after this.
