Detailed Description

Class IRollupSettings, Class IRollupWindow, Class IRollupCallback

Description:

This class makes it possible to get and set the category field (order number) for rollups in the RollupOrder.cfg file. Normally a developer would use this class in order to store the order of rollout panels as a result of a custom handled Drag and Drop operation (see IRollupWindow::HandleRollupCallback() and IRollupCallback::HandleDrop()). First it is necessary to loop through all rollup panels and update the category field in the ICatRegistry

void TaskRollupManager::UpdateCats()
{
    for(int i = 0 ; i < GetNumPanels() ; i++) {
        IRollupPanel *panel = GetPanel(GetPanelDlg(i));
        Class_ID cid;
        SClass_ID sid;
        if(GetEditObjClassID(sid,cid)) {
            MCHAR title[256];
            GetWindowText(panel->GetTitleWnd(), title, 255);
            GetIRollupSettings()->GetCatReg()->UpdateCat(sid,cid, title, panel->GetCategory());
        }
    }
}

After that the ICatRegistry has to be saved with

GetIRollupSettings()->GetCatReg()->Save();

In order to reset the rollup order, one has to call ICatRegistry::DeleteList() for a given superclassid and classid. The structure of the RollupOrder.cfg file (and thus CatRegistry) can be seen as list of items that represent the rollup order for each particular group. A group is identified by a super classid and a classid.

In 3ds Max we can have different possibilities to store the order of rollups. In the Create and Modify Panel we want to store the order of rollups for the currently edited object, which can be an object, or a modifier. Thus the classid and superclassid of the group is the one of the currently edited object. For the Display panel however, we want the rollups to be the same no matter which object is currently selected. To do this, we create a dummy classid which represents the display panel and store the rollup orders under this dummy classid. This classid is identified by the method IRollupCallback::GetEditObjClassID(). Note, that no classddesc has to exist for a dummy classid. The RollupOrder.cfg file will indicate "No ClassName" in case a dummy class id is used.

Member Function Documentation

GetCat()

virtual int GetCat ( SClass_ID  sid, Class_ID  cid, const MCHAR *  title, int  category  )

pure virtual

Remarks

This method gets the category (order field) for the given SuperClass ID, ClassID and Rollup Title.

Parameters:

SClass_ID sid

The superclass ID.

Class_ID cid

The class ID.

MCHAR *title

The rollup title.

int category

`This is used for error checking; it becomes the default value retured by the function if the call fails. So if you pass -1000 and get a return value of -1000, that means the entry was not found.

UpdateCat()

virtual void UpdateCat ( SClass_ID  sid, Class_ID  cid, const MCHAR *  title, int  category  )

pure virtual

Remarks

This method updates (sets) the category (order field) for the given SuperClass ID, ClassID and Rollup Title

Parameters:

SClass_ID sid

The superclass ID.

Class_ID cid

The class ID.

MCHAR *title

The rollup title.

int category

The category.
