PopupMenuCollection Class

Namespace:: ActiproSoftware.UI.WinForms.Controls.Bars

Assembly:: ActiproSoftware.Bars.WinForms.dll

Encapsulates a collection of PopupMenu objects.

public class PopupMenuCollection

Inheritance:: object object

Remarks

This class is a zero-based indexed collection.

Properties

Count

Gets the number of elements contained in the PopupMenuCollection instance.

public virtual int Count { get; }

Property Value

int:: The number of elements contained in the PopupMenuCollection instance.

InnerList

Gets the list of items contained in the collection instance.

protected ArrayList InnerList { get; }

Property Value

ArrayList:: An ArrayList representing the collection instance itself.

IsFixedSize

Gets a value indicating whether the collection has a fixed size.

public virtual bool IsFixedSize { get; }

Property Value

bool:: true if the collection has a fixed size; otherwise, false.

Remarks

A collection with a fixed size does not allow the addition or removal of elements, but it allows the modification of existing elements.

bool:: true if the collection is read-only; otherwise, false.

IsSynchronized

Gets a value indicating whether access to the collection is synchronized (thread-safe).

public virtual bool IsSynchronized { get; }

Property Value

bool:: true if the collection is synchronized (thread-safe); otherwise, false.

Remarks

To guarantee the thread safety of the collection, all operations must be done through the wrapper returned by the SyncRoot property.

this[int]

Gets or sets the PopupMenu at the specified index.

[C#] In C#, this property is the indexer for the PopupMenuCollection class.

public PopupMenu this[int index] { get; set; }

Parameter	Type	Description
index	int	The index of the PopupMenu to return.

Property Value

PopupMenu:: The PopupMenu at the specified index.

this[string]

Gets the PopupMenu with the specified Key.

[C#] In C#, this property is the indexer for the PopupMenuCollection class.

public PopupMenu this[string key] { get; }

Parameter	Type	Description
key	string	The Key of the PopupMenu to return.

Property Value

PopupMenu:: The PopupMenu with the specified Key.

SyncRoot

Gets an Object that can be used to synchronize access to the collection.

public virtual object SyncRoot { get; }

Property Value

object:: An Object that can be used to synchronize access to the collection.

Methods

Add(PopupMenu)

Adds a PopupMenu to the end of the collection.

public int Add(PopupMenu value)

Parameter	Type	Description
value	PopupMenu	The PopupMenu to be added to the end of the collection.

Returns

int:: The collection index at which the PopupMenu has been added.

Clear()

Removes all PopupMenu objects from the collection.

public void Clear()

Contains(PopupMenu)

Returns whether the specified PopupMenu is in the collection.

public virtual bool Contains(PopupMenu value)

Parameter	Type	Description
value	PopupMenu	The PopupMenu to locate in the collection.

Returns

bool:: true if the PopupMenu is found in the collection; otherwise, false.

Contains(string)

Determines whether a PopupMenu is in the collection with the specified Key.

public virtual bool Contains(string key)

Parameter	Type	Description
key	string	The Key of the PopupMenu to locate in the collection.

Returns

bool:: true if the name is found in the collection; otherwise, false.

CopyTo(Array, int)

Copies the entire collection to a compatible one-dimensional Array, starting at the specified index of the target array.

public virtual void CopyTo(Array array, int arrayIndex)

Parameter	Type	Description
array	Array	The one-dimensional `Array` that is the destination of the elements copied from the collection. The `Array` must have zero-based indexing.
arrayIndex	int	The zero-based index in `array` at which copying begins.

GetEnumerator()

Retrieves an IEnumerator object for the entire collection.

public virtual IEnumerator GetEnumerator()

Returns

IEnumerator:: An IEnumerator object for the entire collection

Remarks

Enumerators are intended to be used only to read data in the collection. Enumerators cannot be used to modify the underlying collection.

The enumerator does not have exclusive access to the collection.

When an enumerator is instantiated, it takes a snapshot of the current state of the collection. If changes are made to the collection, such as adding, modifying or deleting elements, the snapshot gets out of sync and the enumerator throws an InvalidOperationException. Two enumerators instantiated from the same collection at the same time can have different snapshots of the collection.

IndexOf(PopupMenu)

Searches for the specified PopupMenu and returns the zero-based index of the first occurrence within the entire collection.

public virtual int IndexOf(PopupMenu value)

Parameter	Type	Description
value	PopupMenu	The PopupMenu to locate in the collection.

Returns

int:: The zero-based index of the first occurrence of the PopupMenu within the entire collection, if found; otherwise, -1.

IndexOf(string)

Searches for the specified Key of a PopupMenu and returns the zero-based index of the first occurrence within the entire collection.

public virtual int IndexOf(string key)

Parameter	Type	Description
key	string	The Key of the PopupMenu to locate in the collection.

Returns

int:: The zero-based index of the first occurrence of the Key within the entire collection, if found; otherwise, -1.

Insert(int, PopupMenu)

Inserts a PopupMenu into the collection at the specified index.

public void Insert(int index, PopupMenu value)

Parameter	Type	Description
index	int	The zero-based index at which the PopupMenu should be inserted.
value	PopupMenu	The PopupMenuto insert.

OnObjectAdded(int, PopupMenu)

Performs additional custom processes after an object is added to the collection.

protected virtual void OnObjectAdded(int index, PopupMenu value)

Parameter	Type	Description
index	int	The zero-based index at which the object was inserted.
value	PopupMenu	The object that was inserted.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified object is added.

OnObjectAdding(int, PopupMenu)

Performs additional custom processes before an object is added to the collection.

protected virtual void OnObjectAdding(int index, PopupMenu value)

Parameter	Type	Description
index	int	The zero-based index at which the object was inserted.
value	PopupMenu	The object that was inserted.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified object is added.

OnObjectRemoved(int, PopupMenu)

Performs additional custom processes after an object is removed from the collection.

protected virtual void OnObjectRemoved(int index, PopupMenu value)

Parameter	Type	Description
index	int	The zero-based index from which the object was removed.
value	PopupMenu	The object that was removed.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action after the specified object is removed.

OnObjectRemoving(int, PopupMenu)

Performs additional custom processes before an object is removed from the collection.

protected virtual void OnObjectRemoving(int index, PopupMenu value)

Parameter	Type	Description
index	int	The zero-based index from which the object was removed.
value	PopupMenu	The object that was removed.

Remarks

The default implementation of this method is intended to be overridden by a derived class to perform some action before the specified object is removed.

OnValidate(PopupMenu, int)

Performs additional custom processes when validating a value.

protected virtual void OnValidate(PopupMenu value, int existingIndex)

Parameter	Type	Description
value	PopupMenu	The object to validate.
existingIndex	int	The index within the collection of the object that would be replaced by the value.

Remarks

The default implementation of this method determines whether value is null, and if so, throws ArgumentNullException. It is intended to be overridden by a derived class to perform additional action when the specified element is validated.

Remove(PopupMenu)

Removes the first occurrence of a specific PopupMenu from the collection.

public void Remove(PopupMenu value)

Parameter	Type	Description
value	PopupMenu	The PopupMenu to remove from the collection.

Remarks

The elements that follow the removed element move up to occupy the vacated spot. The indexes of the elements that are moved are also updated.

RemoveAt(int)

Removes the PopupMenu at the specified index of the collection.

public void RemoveAt(int index)

Parameter	Type	Description
index	int	The zero-based index of the PopupMenu to remove.
