範例

下列程式碼範例示範如何使用 ISupportInitialize 介面來初始化三個 TrackBar 控制項。The following code example demonstrates how to use the ISupportInitialize interface to initialize three TrackBar controls.

(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar1))->BeginInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar2))->BeginInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar3))->BeginInit();
this->SuspendLayout();

// 
// trackBar1
// 
this->trackBar1->Location = System::Drawing::Point( 160, 400 );
this->trackBar1->Name = "trackBar1";
this->trackBar1->TabIndex = 1;
this->trackBar1->Scroll += gcnew System::EventHandler( this, &Form1::trackBar_Scroll );

// 
// trackBar2
// 
this->trackBar2->Location = System::Drawing::Point( 608, 40 );
this->trackBar2->Name = "trackBar2";
this->trackBar2->TabIndex = 2;
this->trackBar2->Scroll += gcnew System::EventHandler( this, &Form1::trackBar_Scroll );

// 
// trackBar3
// 
this->trackBar3->Location = System::Drawing::Point( 56, 40 );
this->trackBar3->Name = "trackBar3";
this->trackBar3->TabIndex = 3;
this->trackBar3->Scroll += gcnew System::EventHandler( this, &Form1::trackBar_Scroll );
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar1))->EndInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar2))->EndInit();
(dynamic_cast<System::ComponentModel::ISupportInitialize^>(this->trackBar3))->EndInit();

((System.ComponentModel.ISupportInitialize)(this.trackBar1)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.trackBar2)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.trackBar3)).BeginInit();
this.SuspendLayout();
// 
// trackBar1
// 
this.trackBar1.Location = new System.Drawing.Point(160, 400);
this.trackBar1.Name = "trackBar1";
this.trackBar1.TabIndex = 1;
this.trackBar1.Scroll += new System.EventHandler(this.trackBar_Scroll);
// 
// trackBar2
// 
this.trackBar2.Location = new System.Drawing.Point(608, 40);
this.trackBar2.Name = "trackBar2";
this.trackBar2.TabIndex = 2;
this.trackBar2.Scroll += new System.EventHandler(this.trackBar_Scroll);
// 
// trackBar3
// 
this.trackBar3.Location = new System.Drawing.Point(56, 40);
this.trackBar3.Name = "trackBar3";
this.trackBar3.TabIndex = 3;
this.trackBar3.Scroll += new System.EventHandler(this.trackBar_Scroll);
((System.ComponentModel.ISupportInitialize)(this.trackBar1)).EndInit();
((System.ComponentModel.ISupportInitialize)(this.trackBar2)).EndInit();
((System.ComponentModel.ISupportInitialize)(this.trackBar3)).EndInit();
CType(Me.trackBar1, System.ComponentModel.ISupportInitialize).BeginInit()
CType(Me.trackBar2, System.ComponentModel.ISupportInitialize).BeginInit()
CType(Me.trackBar3, System.ComponentModel.ISupportInitialize).BeginInit()
Me.SuspendLayout()
'
'trackBar1
'
Me.trackBar1.Location = New System.Drawing.Point(160, 400)
Me.trackBar1.Name = "trackBar1"
Me.trackBar1.TabIndex = 1
'
'trackBar2
'
Me.trackBar2.Location = New System.Drawing.Point(608, 40)
Me.trackBar2.Name = "trackBar2"
Me.trackBar2.TabIndex = 2
'
'trackBar3
'
Me.trackBar3.Location = New System.Drawing.Point(56, 40)
Me.trackBar3.Name = "trackBar3"
Me.trackBar3.TabIndex = 3
CType(Me.trackBar1, System.ComponentModel.ISupportInitialize).EndInit()
CType(Me.trackBar2, System.ComponentModel.ISupportInitialize).EndInit()
CType(Me.trackBar3, System.ComponentModel.ISupportInitialize).EndInit()

備註

ISupportInitialize 允許控制項將多個屬性指派優化。ISupportInitialize allows controls to optimize multiple property assignments. 因此,您可以在設計階段初始化共同相依屬性或 batch 設定多個屬性。As a result, you can initialize co-dependent properties or batch set multiple properties at design time.

呼叫 BeginInit 方法,以通知物件正在啟動初始化。Call the BeginInit method to signal the object that initialization is starting. 呼叫 EndInit 方法,以通知初始化已完成。Call the EndInit method to signal that initialization is complete.

方法

BeginInit()

發出初始化正在啟動之物件的訊號。Signals the object that initialization is starting.

EndInit()

發出初始化完成之物件的訊號。Signals the object that initialization is complete.
