class TGRedirectOutputGuard


TGRedirectOutputGuard

This class provides output redirection to a TGTextView in guaranteed
exception safe way. Use like this:
{
TGRedirectOutputGuard guard(textview);
... // do something
guard.Update();
... // do something else
}
when guard goes out of scope, Update() is called to flush what left
on the screed and the output is automatically redirected again to
the standard units.
The exception mechanism takes care of calling the dtors
of local objects so it is exception safe.
Optionally the output can also be saved into a file:
{
TGRedirectOutputGuard guard(textview, file, mode);
... // do something
}
