.SH DESCRIPTION
|
|
.PP
|
|
\fBTk_MainLoop\fR is a procedure that loops repeatedly calling
|
|
\fBTcl_DoOneEvent\fR. 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.
