Member Function Documentation

virtual int32 IGroupItemUtils::AccumulateTransformedGroups ( const UIDList &  items, UIDList *  transformedGroups  ) const

pure virtual

Iterate through the given items and get the transformed(skew, scale or rotate) group items.

Parameters

items	IN the given items.
transformedGroups	OUT the item list contains the transformed group items.

Returns

int32 the number of transformed group items.

virtual bool16 IGroupItemUtils::CanEnableGroup ( const UIDList *  items, IDocumentLayer *  targetLayer = nil  ) const

pure virtual

Check if the give itmes can be grouped on the given document layer or not. If targetLayer is nil, active layer of front window will be used.

Parameters

items	IN the items to check.
targetLayer	IN the document layer.

Returns

bool16 kTrue if items can be grouped, otherwise return kFalse.

virtual bool16 IGroupItemUtils::CanEnableUngroup ( const UIDList *  items ) const

pure virtual

Check if the give itmes can be ungrouped or not.

Parameters

items

IN the given items.

Returns

bool16 kTrue if items can be ungrouped, otherwise return kFalse.

virtual bool16 IGroupItemUtils::HaveBothLockedAndUnLockedItems ( const UIDList &  itemList ) const

pure virtual

Check if the give itmes has both locked and unlocked items or not.

Parameters

items

IN the items to check.

Returns

bool16 kTrue if there are mixed items, otherwise return kFalse.

virtual bool16 IGroupItemUtils::HaveBothOverrideableAndNonOverrideableItems ( const UIDList &  itemList ) const

pure virtual

Check if the give itmes has both overrideable or not overrideable items or not.

Parameters

items

IN the items to check.

Returns

bool16 kTrue if there are mixed items, otherwise return kFalse.
