Specify the width and height of the main window/Tkx Tips
Use the g_wm_geometry method to specify the width and height of the main window.
# Width and height
$mw->g_wm_geometry("600x300");
Width and height are specified in the format "width x height".
If you want to specify the display position at the same time, do as follows.
$mw->g_wm_geometry("600x300 + 200 + 400");
Below is an example.
use strict;
use warnings;
use Tkx;
my $mw = Tkx::widget->new(".");
$mw->g_wm_geometry("600x300");
Tkx::MainLoop ();
