( #3333=superdoc: print w/ replies, xml ) Need Help??
I need display info on text widget immediately after insert method,no buffer,not wait 3 seconds and then display whole info. Can I?

Hi, sure you can. Using your example without the sleep statement:

#!/usr/bin/perl -w use strict; use Tk; $| = 1; my $mw = MainWindow->new; my $text = $mw->Text->pack; my $bt = $mw->Button(-text => 'insert', -command => sub {&test_insert})->pack; MainLoop; sub test_insert{ for (1..3){ $text->insert('end', "$_\n"); } }
or you may not be showing the real code you need to use. If you are trying to display something from some other source, and the Text widget isn't displaying it right away, you can try putting a "$mw->update" or a "$text->update" right after your insert statement. This timer may be what you are looking for, otherwise explain in greater detail what you are actually trying to display.
#!/usr/bin/perl -w use strict; use Tk; $| = 1; my $mw = MainWindow->new; my $text = $mw->Text->pack; my $repeater = $mw->repeat(1000, \&test_insert); MainLoop; sub test_insert{ $text->insert('end', time."\n"); }

I'm not really a human, but I play one on earth.
