34# Lazarus Toturial Creating TTabControl uses tabs to manage compenets and data in your program

TTabControl ttabcontrol.png is a descendant of TWinControl and can be found on the Common Controls tab of the Component Palette. It is a tabbed container component which looks identical to a TPageControl. However, there is a fundamental difference because the control always shows the same page whichever tab is selected. In fact, it containts only a single page. The idea behind this concept is illustrated best by an editor or viewer for text files: When the TabControl contains a TMemo then the individual tabs refer to the files loaded into the memo; whenever the active tab changes another file is loaded into the (same) memo. Since the TTabControl contains only a single page there is no Pages property as for the TPageControl. The individual tab captions are stored in a TStrings property named Tabs. The currently selected tab can be identified by means of its index, TabIndex.
