Remarks
Both the event triggered when the button is clicked and the description that shows up in the status bar are based on the properties of the associated menu. Thus, the toolbar controls the action of the application indirectly, through its associated menu.
Specifying a toolbar by calling this method for each button might seem cumbersome. The recommended way to define the toolbar is to use the Menu Editor, which automatically generates code to lay out the toolbar.
Note that the user can modify the set of button items on the toolbar with the configuration dialog. The program does not need to concern itself with what buttons exist, since the events come in as if they were menu selections.
In order to reduce "visual noise" (undesirable blinking and flicker), the toolbar does not immediately reflect a button added with InsertItem(). Instead, you must call Update() to make all the new buttons show up at once. The Show() method automatically updates the display. For toolbars that are defined once and for all and attached to a window, there is no need for explicitly calling Update(), it is intended only for toolbars that change their button configuration on the fly.
