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 );
}
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)
End Sub
When DropDownArrows is set to false
, no down arrows display on drop-down style toolbar buttons. When the user clicks the drop-down button on the toolbar, the menu drops down for selection. When the drop-down arrow is displayed, the user must press the down arrow to display the menu.
