Tk_MainLoop - loop for events until all windows are deleted

=for category C Programming


B<#include E<lt>tk.hE<gt>>



B<Tk_MainLoop> is a procedure that loops repeatedly calling
B<Tcl_DoOneEvent>.  It returns only when there are no applications
left in this process (i.e. no main windows exist anymore).  Most
windowing applications will call B<Tk_MainLoop> after
initialization; the main execution of the application will consist
entirely of callbacks invoked via B<Tcl_DoOneEvent>.
