Beispiele

Im folgenden Codebeispiel wird die Verwendung der ISupportInitialize Schnittstelle zum Initialisieren von drei TrackBar Steuerelementen veranschaulicht.

(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();

trackBar1.BeginInit();
