Provides a TCollection that can be sorted.
Component users would descend from this class and either assign a
OnCompare event handler or override the
Compare and
IsSortable functions. TCollectionItem descendants would call the
SortItem method when the property the collection sorts on is changed

|
Represents method AssignTo(TPersistent). (Inherited from Structures.TGCollection.)

|
Compare(TCollectionItem,TCollectionItem)
|
Compares the two collection items and returns -1, 0, or 1. The Sort method uses the Compare method to determine the sort order of the items.
 Warning
|
The OnCompare event handler must be defined
|
|
|
CustomSort(TCollectionItemCompareEvent)
|
Sorts the collection using a custom sorting function. Use this function to sort the collection using a different function than the OnCompare event.
|
|
IndexOf(String)
|
Returns the index of the collection item where CollectionItem.DisplayName equals the DisplayName search parameter. The comparison is case sensitive.
If no collection item equals the parameter, the function returns a -1.
|
|
IsSortable
|
Returns true if this collection can be sorted, i.e., does it have an OnCompare event.
|
|
Notify(TCollectionItem,Classes)
|
Represents method Notify(TCollectionItem,Classes).
|
|
QuickSort(Integer,Integer,TCollectionItemCompareEvent)
|
Sorts the collection using the Quicksort algorithm. The QuickSort method calls the Compare method to determine the sort order of the items.
|
|
Sort
|
Sorts the collection
|
|
SortItem(TCollectionItem)
