Examples

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();

trackBar1.BeginInit();
trackBar2.BeginInit();
trackBar3.BeginInit();
SuspendLayout();
//
// trackBar1
//
trackBar1.Location = new Point(160, 400);
trackBar1.Name = "trackBar1";
trackBar1.TabIndex = 1;
trackBar1.Scroll += trackBar_Scroll;
//

//
trackBar2.Location = new Point(608, 40);
trackBar2.Name = "trackBar2";
trackBar2.TabIndex = 2;
trackBar2.Scroll += trackBar_Scroll;
//
// trackBar3
//
trackBar3.Location = new Point(56, 40);
trackBar3.Name = "trackBar3";
trackBar3.TabIndex = 3;
trackBar3.Scroll += trackBar_Scroll;
trackBar1.EndInit();
trackBar2.EndInit();
trackBar3.EndInit();
