Detailed Description

Browser widget for managing opened tables.

Synopsis

TBBrowser is a container for multiple TBTableTabs. Its main responsibility is to keep these tabs up-to-date and handle their opening and closing. TBBrowser is the main interface for the GUI of the table browser and thus also provides public methods to operate on opened tables.
