// TGTab, TGTabElement, TGTabLayout //

// A tab widget contains a set of composite frames each with a little //
// tab with a name (like a set of folders with tabs). //
// //
// The TGTab is user callable. The TGTabElement and TGTabLayout are //
// is a service classes of the tab widget. //
// //
// Clicking on a tab will bring the associated composite frame to the //
// front and generate the following event: //
// kC_COMMAND, kCM_TAB, tab id, 0. //
