Comments

A toolbar is made up of one or more tools. The LTOOLBARINFO structure contains information about the toolbar in general. Information about each tool that makes up the toolbar is contained in an LTOOLBARINFO structure. Each tool in a toolbar may have one or more buttons associated with it. A tool with more than one button associated with it is said to be a sub-toolbar. Information about the button(s) associated with a tool in the toolbar is contained in one or more LBUTTONINFO structures.

Buttons on a toolbar may have the same ID number. If a function is called that uses a button ID, such as L_TBAddButton, then the toolkit function will act on the first button found with the specified ID.
