I am making an "all-in-one calculator" (I guess). Here is my code (I know I do not have all subroutines defined, I'm still working on this as you can see):
use 5.12.4;
use warnings;
use Tk;
##### Create MainWindow #####
my $button_menu = new MainWindow;
#############################
##### MainWindow Buttons#####
my $calculator_button = $button_menu->Button(-text=>"Calculator",
-width=>10,
-relief=> 'raised',
-command=>\&open_calculator)->pack();
my $formulas_button = $button_menu->Button(-text=>"Formulas",
-width=>10,
-relief=> 'raised',
-command=>\&open_formulas)->pack();
my $lcf_button = $button_menu->Button(-text=>"Find LCF",
-width=>10,
-relief=> 'raised',
-command=>\&open_lcf)->pack();
my $gcf_button = $button_menu->Button(-text=>"Find GCF",
-width=>10,
-relief=> 'raised',
-command=>\&open_gcf)->pack();
#############################
sub open_calculator{
system(qq{start "C:\\Windows\\system32\\calc.exe"});
}
MainLoop;
Why does the system function not open the Windows calculator? Also, is there any source code I could use to make a basic calculator in Tk?
Thanks!
