It returns only when there are no applications left in this process (i.e. no main windows exist anymore). Most windowing applications will call \fBTk_MainLoop\fR after initialization; the main execution of the application will consist entirely of callbacks invoked via \fBTcl_DoOneEvent\fR. .SH KEYWORDS application, event, main loop
