注解

如果按钮 Style 设置为, DropDownButton 则可以指定在 MenuItem 按下下拉按钮时要显示的。If the button Style is set to DropDownButton you can specify a MenuItem to be displayed when the drop-down button is pressed. 如果样式设置为 ToolBarButtonStyle.Separator ,则工具栏按钮将显示为按钮分隔符而不是按钮。If the style is set to ToolBarButtonStyle.Separator, the toolbar button appears as a button separator and not as a button. ToolBarButtonStyle.ToggleButton样式使工具栏按钮的行为类似于切换按钮; 它可以处于打开或关闭状态。The ToolBarButtonStyle.ToggleButton style causes the toolbar button to act like a toggle button; it can be in an on or off state.
