例

次のコード例ではToolBar 、コントロールを作成し、その共通プロパティのいくつかを設定Formして、に追加します。The following code example creates a ToolBar control, sets some of its common properties, and adds it to a Form. デリゲートは、 ButtonClickイベントおよびButtonDropDownイベントにも追加されます。Delegates are also added to the ButtonClick and ButtonDropDown events. この例では、 ToolBar toolBar1という名前ImageListのimageList1とが宣言されている必要があります。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 );
}

private void AddToolBar()
{
   // Add a toolbar and set some of its properties.
   toolBar1 = new ToolBar();
   toolBar1.Appearance = System.Windows.Forms.ToolBarAppearance.Flat;
   toolBar1.BorderStyle = System.Windows.Forms.BorderStyle.None;
   toolBar1.Buttons.Add(this.toolBarButton1);
   toolBar1.ButtonSize = new System.Drawing.Size(24, 24);
   toolBar1.Divider = true;
   toolBar1.DropDownArrows = true;
   toolBar1.ImageList = this.imageList1;
   toolBar1.ShowToolTips = true;
   toolBar1.Size = new 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 += 
     new ToolBarButtonClickEventHandler(toolBar1_ButtonDropDown);
   toolBar1.ButtonClick += 
     new ToolBarButtonClickEventHandler(toolBar1_ButtonClicked);

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

Private Sub AddToolBar()
   ' Add a toolbar and set some of its properties.
   toolBar1 = New ToolBar()
   toolBar1.Appearance = System.Windows.Forms.ToolBarAppearance.Flat
   toolBar1.BorderStyle = System.Windows.Forms.BorderStyle.None
   toolBar1.Buttons.Add(Me.toolBarButton1)
   toolBar1.ButtonSize = New System.Drawing.Size(24, 24)
   toolBar1.Divider = True
   toolBar1.DropDownArrows = True
   toolBar1.ImageList = Me.imageList1
   toolBar1.ShowToolTips = True
   toolBar1.Size = New 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.
   AddHandler toolBar1.ButtonDropDown, AddressOf toolBar1_ButtonDropDown
   AddHandler toolBar1.ButtonClick, AddressOf toolBar1_ButtonClicked

   ' Add the toolbar to the form.
   Me.Controls.Add(toolBar1)
