Příklady

Následující příklad kódu ukazuje, jak použít rozhraní ISupportInitialize k inicializaci tří TrackBarch ovládacích prvků.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();

Poznámky

ISupportInitialize umožňuje ovládacím prvkům optimalizovat více přiřazení vlastností.ISupportInitialize allows controls to optimize multiple property assignments. V důsledku toho můžete inicializovat souběžně závislé vlastnosti nebo sadu dávek s více vlastnostmi v době návrhu.As a result, you can initialize co-dependent properties or batch set multiple properties at design time.

Zavolejte metodu BeginInit k signalizaci objektu, který se spouští inicializací.Call the BeginInit method to signal the object that initialization is starting. Zavolejte metodu EndInit k signalizaci, že se inicializace dokončila.Call the EndInit method to signal that initialization is complete.

Metody

BeginInit()

Signalizuje objekt, který se spouští při inicializaci.Signals the object that initialization is starting.

EndInit()

Signalizuje dokončení objektu, který se inicializuje.Signals the object that initialization is complete.
