DesignTimeVisibleAttribute 類別

定義

DesignTimeVisibleAttribute 標記元件的可視性。DesignTimeVisibleAttribute marks a component's visibility. 如果有 Yes,視覺化設計工具 (Visual Designer) 可以在設計工具上顯示這個元件。If Yes is present, a visual designer can show this component on a designer.

public ref class DesignTimeVisibleAttribute sealed : Attribute
public sealed class DesignTimeVisibleAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface)]
public sealed class DesignTimeVisibleAttribute : Attribute
type DesignTimeVisibleAttribute = class
    inherit Attribute
[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface)>]
type DesignTimeVisibleAttribute = class
    inherit Attribute
Public NotInheritable Class DesignTimeVisibleAttribute
Inherits Attribute

備註

DesignTimeVisibleAttribute是設計工具的提示。The DesignTimeVisibleAttribute is a hint to the Designer. 設計工具會忽略具有 UI 目前狀態之元件的這個屬性。The Designer will ignore this attribute for components that have a UI presence. 它只能套用至類別。It can only be applied to classes.

DesignTimeVisibleAttribute當您的控制項接受子元件時,最有用。The DesignTimeVisibleAttribute is most useful when you have a control that accepts child components. 例如, System.Windows.Forms.TreeView 控制項的節點專案應該不會出現在元件匣中,因為它們是由控制項繪製 System.Windows.Forms.TreeViewFor example, the System.Windows.Forms.TreeView control's node items should not appear in the component tray because they are drawn by the System.Windows.Forms.TreeView control.

建構函式

DesignTimeVisibleAttribute()

建立新的 DesignTimeVisibleAttribute,預設值為 falseCreates a new DesignTimeVisibleAttribute set to the default value of false.

DesignTimeVisibleAttribute(Boolean)

建立新的 DesignTimeVisibleAttribute,並將其 Visible 屬性設定為 visible 中的指定值。Creates a new DesignTimeVisibleAttribute with the Visible property set to the given value in visible.

欄位

Default

預設可視性,即 YesThe default visibility which is Yes.

No

將元件標記為在視覺化設計工具中不可見。Marks a component as not visible in a visual designer.

Yes

將元件標記為在視覺化設計工具中可見。Marks a component as visible in a visual designer.

屬性

TypeId

在衍生類別中實作時,取得這個 Attribute 的唯一識別碼。When implemented in a derived class, gets a unique identifier for this Attribute.

Visible

取得或設定元件是否應該在設計階段顯示。Gets or sets whether the component should be shown at design time.

方法

Equals(Object)

傳回值,這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object.

GetHashCode()

傳回這個執行個體的雜湊碼。Returns the hash code for this instance.

GetType()

取得目前執行個體的 TypeGets the Type of the current instance.

(繼承來源 Object)
IsDefaultAttribute()

取得值,表示此執行個體是否等於 Default 值。Gets a value indicating if this instance is equal to the Default value.

Match(Object)

在衍生類別中覆寫時,會傳回值,表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(繼承來源 Attribute)
MemberwiseClone()

建立目前 Object 的淺層複製。Creates a shallow copy of the current Object.

(繼承來源 Object)
ToString()

傳回代表目前物件的字串。Returns a string that represents the current object.

(繼承來源 Object)

明確介面實作

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers.

(繼承來源 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

擷取物件的類型資訊,可以用來取得介面的類型資訊。Retrieves the type information for an object, which can be used to get the type information for an interface.

(繼承來源 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

擷取物件提供的類型資訊介面數目 (0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(繼承來源 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供物件所公開的屬性和方法的存取權。Provides access to properties and methods exposed by an object.
