示例

下面的代码示例将创建ToolBar和三个ToolBarButton控件。The following code example creates a ToolBar and three ToolBarButton controls. 工具栏按钮分配给按钮集合、 集合分配给工具栏和工具栏添加到窗体。The toolbar buttons are assigned to the button collection, the collection is assigned to the toolbar, and the toolbar is added to the form. ButtonClick工具栏上,事件Button属性的ToolBarButtonClickEventArgs计算和适当的对话框打开。On the ButtonClick event of the toolbar, the Button property of the ToolBarButtonClickEventArgs is evaluated and the appropriate dialog box opened. 此代码需要Form、 一个OpenFileDialogSaveFileDialog,和一个PrintDialog所有已创建。This code requires that a Form, an OpenFileDialog, a SaveFileDialog, and a PrintDialog have all been created.

注解

ToolBarButton 控件为父级ToolBar控件。ToolBarButton controls are parented by ToolBar controls. 要设置创建工具栏按钮后的常见属性是TextImageIndexCommon properties to set once the toolbar button has been created are Text and ImageIndex. 设置Text的按钮以显示文本下方或右侧的图像的属性。Set the Text property of the button to display text beneath or to the right of the image. 若要通过创建将图像分配给按钮ImageList,将其分配给ImageList属性工具栏; 然后将分配到的映像索引值ImageIndex按钮的属性。To assign images to the buttons by creating an ImageList, assigning it to the ImageList property of the toolbar; then assign the image index value to the ImageIndex property of the button.

若要更改分配给工具栏的工具栏按钮的外观,请设置Appearance父工具栏控件的属性。To change the appearance of the toolbar buttons assigned to the toolbar, set the Appearance property of the parent toolbar control. ToolBarAppearance.Flat外观使按钮为平面外观。The ToolBarAppearance.Flat appearance gives the buttons a flat appearance. 在鼠标指针移到按钮的外观变为三维上。As the mouse pointer moves over the buttons, their appearance changes to three-dimensional. 按钮分隔符将显示为线,而不是当按钮具有平面外观时,按钮之间的空格。Button separators appear as lines rather than spaces between the buttons when the buttons have a flat appearance. 如果Appearance属性设置为ToolBarAppearance.Normal、 凸起和三维,显示的按钮和分隔符将显示为在按钮之间间隙。If the Appearance property is set to ToolBarAppearance.Normal, the buttons appear raised and three-dimensional, and the separators appear as a gap between the buttons.

可以将分配ContextMenu向按钮如果Style属性设置为ToolBarButtonStyle.DropDownYou can assign a ContextMenu to a button if the Style property is set to ToolBarButtonStyle.DropDown. 单击该按钮,将显示已分配的菜单。When the button is clicked, the assigned menu is displayed.

若要创建的集合ToolBarButton控件以显示有关ToolBar,使用单独添加按钮Add方法的Buttons属性。To create a collection of ToolBarButton controls to display on a ToolBar, add the buttons individually by using the Add method of the Buttons property. 或者,可以添加多个工具栏按钮使用AddRange方法。Alternatively, you can add several toolbar buttons using the AddRange method.
