The following code example creates a ToolBar control, sets some of its common properties, and adds it to a Form. Delegates are also added to the ButtonClick and ButtonDropDown events. This example requires that a ToolBar named toolBar1 and an ImageList named imageList1 have been declared.

void AddToolBar()
{

   // Add a toolbar and set some of its properties.
   toolBar1 = gcnew ToolBar;
   toolBar1->Appearance = System::Windows::Forms::ToolBarAppearance::Flat;
   toolBar1->BorderStyle = System::Windows::Forms::BorderStyle::None;
   toolBar1->Buttons->Add( this->toolBarButton1 );
   toolBar1->ButtonSize = System::Drawing::Size( 24, 24 );
   toolBar1->Divider = true;
   toolBar1->DropDownArrows = true;
   toolBar1->ImageList = this->imageList1;
   toolBar1->ShowToolTips = true;
   toolBar1->Size = System::Drawing::Size( 292, 25 );
   toolBar1->TabIndex = 0;
   toolBar1->TextAlign = System::Windows::Forms::ToolBarTextAlign::Right;
   toolBar1->Wrappable = false;

   // Add handlers for the ButtonClick and ButtonDropDown events.
   toolBar1->ButtonDropDown += gcnew ToolBarButtonClickEventHandler( this, &MyToolBar::toolBar1_ButtonDropDown );
   toolBar1->ButtonClick += gcnew ToolBarButtonClickEventHandler( this, &MyToolBar::toolBar1_ButtonClicked );

   // Add the toolbar to the form.
   this->Controls->Add( toolBar1 );
}
