in reply to Graphic Fullscreen Program ?
Here is a almost fully working example. In case this is homework, I left out the image, so you will have to figure that out for yourself. (Hint: just look at perldoc Tk::Canvas for createImage. If you need to resize it first, look at Tk::Photo, or groups.google search for "Perl tk canvas image" ).
#!/usr/bin/perl -w use warnings; use strict; use Tk; use Tk::LabEntry; my $mw = MainWindow->new; my $vh = $mw->vrootheight; my $vw = $mw->vrootwidth; # Note that the 'virtual window' height and width are $vh and $vw # respectively, so we use those dimensions for our Canvas height # and width, and let the Canvas expand and fill in both x and y # directions. # my $canvas = $mw->Canvas( -width => $vw, -height => $vh, -background =>'blue', -takefocus =>0); # so canvas dosn't take focus on tab press $canvas->pack(-expand => 1, -fill => 'both'); #just for fun instead of gif image $canvas->createRectangle(100, 100, 150, 150, -fill => 'orange'); my %window; my $ypos = 0; foreach ('First', 'Last'){ $window{$_}{'obj'} = $canvas->LabEntry(-label=> $_); $window{$_}{'obj'}->Subwidget('entry')->configure( -background=>'yellow', -textvariable => \$window{$_}{'data'}, ); $window{$_}{'obj'}->configure(-labelPack=>[-side=>'left']); $canvas->createWindow($vw/2, $vh/2 + $ypos, -window=> $window{$_}{'obj'}); $ypos += 40; } $window{'First'}{'obj'}->focus; $window{'Ok'}{'obj'} = $canvas->Button(-text=> 'Ok', -command=> sub{ foreach ('First', 'Last'){ print "$_ , $window{$_}{'data'}\n"; + } exit; } ); $canvas->createWindow($vw/2, $vh/2 + $ypos + 50, -window=> $window{'Ok'}{'obj'}); MainLoop;
