C# Класс SIL.FieldWorks.Common.Widgets.FwListBox.ObjectCollection

Like ListBox, FwListBox defines an ObjectCollection class for the items in the list. This class provides a subset of the functionality of the ArrayList used to implement it. The reason for not using an ArrayList is that operations that change the contents of the list have to have side effects on the control.

Открытые методы

Метод	Описание
Add ( object item ) : int	Add an item to the collection and the display.
AddRange ( IEnumerable items ) : void	Add a whole collection of objects.
CheckDisposed ( ) : void	Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.
Clear ( ) : void	Clear all items. Enhance JohnT: add the version that takes an ObjectCollection.
Contains ( object item ) : bool	See if the item is present.
Dispose ( ) : void	Must not be virtual.
GetEnumerator ( ) : IEnumerator	Get an enumerator for the list.
IndexOf ( object item ) : int	Find the zero-based position of the item, or -1 if not found.
Insert ( int index, object item ) : void	Insert the specified item at the specified position.
ObjectCollection ( IFwListBox owner ) : System	Construct empty.
ObjectCollection ( IFwListBox owner, object values ) : System	Construct with supplied initial items.
Remove ( object item ) : void
RemoveAt ( int index ) : void
this ( int index ) : object	Indexer. Set must modify the display.

Защищенные методы

Метод	Описание
Dispose ( bool disposing ) : void	Executes in two distinct scenarios. 1. If disposing is true, the method has been called directly or indirectly by a user's code via the Dispose method. Both managed and unmanaged resources can be disposed. 2. If disposing is false, the method has been called by the runtime from inside the finalizer and you should not reference (access) other managed objects, as they already have been garbage collected. Only unmanaged resources can be disposed. If any exceptions are thrown, that is fine. If the method is being done in a finalizer, it will be ignored. If it is thrown by client code calling Dispose, it needs to be handled by fixing the bug. If subclasses override this method, they should call the base implementation.
InsertItemAtIndex ( int index, object item ) : void	Shared function for Insert and Add.

Приватные методы

Метод	Описание
ClearAllItems ( ) : void
ICollection ( Array dest, int arrayIndex ) : void	Copy to a destination array.

Описание методов

Add() публичный Метод

Add an item to the collection and the display.

public Add ( object item ) : int
item	object
Результат	int

AddRange() публичный Метод

Add a whole collection of objects.

public AddRange ( IEnumerable items ) : void
items	IEnumerable
Результат	void

CheckDisposed() публичный Метод

Check to see if the object has been disposed. All public Properties and Methods should call this before doing anything else.

public CheckDisposed ( ) : void
Результат	void

Clear() публичный Метод

Clear all items.

Enhance JohnT: add the version that takes an ObjectCollection.

public Clear ( ) : void
Результат	void

Contains() публичный Метод

See if the item is present.

public Contains ( object item ) : bool
item	object
Результат	bool

Dispose() публичный Метод

Must not be virtual.

public Dispose ( ) : void
Результат	void

Dispose() защищенный Метод

Executes in two distinct scenarios. 1. If disposing is true, the method has been called directly or indirectly by a user's code via the Dispose method. Both managed and unmanaged resources can be disposed. 2. If disposing is false, the method has been called by the runtime from inside the finalizer and you should not reference (access) other managed objects, as they already have been garbage collected. Only unmanaged resources can be disposed.

If any exceptions are thrown, that is fine. If the method is being done in a finalizer, it will be ignored. If it is thrown by client code calling Dispose, it needs to be handled by fixing the bug. If subclasses override this method, they should call the base implementation.

protected Dispose ( bool disposing ) : void
