ZJ.Mike.2009 has asked for the wisdom of the Perl Monks concerning the following question:

Just starting to play with Prima. Wrote the following code:
use strict; use warnings; use Prima qw(Application Edit Buttons); my $window = new Prima::MainWindow( size => [ 250, 350] ); my $display_field = $window->insert( Edit => size => [ 200, 300], text => '', centered => 1, ); my $butoon = $window->insert( Button => size => [ 50, 20], text => 'Click', place => { x => 120, y => 340 }, onClick => \&button_Click, ); sub button_Click { for (1..5) { $display_field->insert_text("$_\n\n"); } } run Prima;
I expected the display field shows 1 2 3 4 and 5 separately in each line from top to bottom but Prima gives me 5 4 3 2 1. Things get displayed upside down.

I've noticed the x and y coordinates in Prima are different. For example, the x coordinate in Prima starts from left bottom corner of the widget, rather than the usual left top corner. I've found some seemingly relevant methods like translate, but I cant't seem to figure out how to get things displayed the expected way? Does someone have some ideas?

Thanks in advance.
