It's not very obvious why, but..... `sub history { $test = $main->Entry->pack(); # $ragimenu->Menubutton( -state => 'disabled' ); $ragimenu->entryconfigure(1, -state => 'disabled'); }` [download] I'm not really a human, but I play one on earth. flash japh	[reply] [d/l]

Well I suppose we could guess this is a Tk question, although for all we know it could be any GUI, html etc, or even block character pseudo-graphics on an IBM terminal... ! Best is to publish your code here anyway; we'll see what it is and hopefully the solution. One world, one people	[reply]

use Tk; $main=MainWindow->new; $menubar=$main->Frame->pack(-side=>'top',-fill=>'x'); $ragimenu= $menubar->Menubutton(-text=>'Ragi')->pack(-side=>'left'); $ragimenu->command(-label=>'History',-command=>\&history); $searchbar=$menubar->Menubutton(-text=>'Search')->pack(-side=>'left'); $searchbar->command(-label=>'Literature search',-command=>\&literature); $searchbar->command(-label=>'Genome search',-command=>\&genome); sub history { $test=$main->Entry->pack(); $ragimenu->Menubutton(-state=>'disabled'); } MainLoop; i have tried by placing the $ragimenu->Menubutton(-state=>'disabled'); but that to does't works it still active	[reply]

Unfortunately I can't install Tk.pm in the office, so I am flying blind here. But the next thing I would try is moving that line into the main loop, instead of in the history subroutine. One world, one people	[reply]
