	use strict;
	use warnings;
	
	my $app = TkApp->new();
	$app->run();

=head1 DESCRIPTION

=head1 METHODS

=head2 new()

Ctor. Calls _build_gui.

=cut

sub new {
	my $class = shift;
	
	my $self = bless({}, $class);
	
	my $mw = Tk::MainWindow->new();
	$self->set_mw($mw);
	
	$self->_build_gui();
	
	return $self;
} # /new




=head2 _build_gui()

Build GUI. Set up widgets etc. Positioning is done here, too.

Private method. Don't call it directly, as this will be done by new().

=cut

sub _build_gui {
	my $self = shift;
	my $mw = $self->get_mw();
	my %gui = ();

	# -- menu
	my $menuitems = [
		[Cascade => "~File", -menuitems =>
			[
				[Button => "Some ~Method", -command => sub{
					return $self->some_method();
				}],
				[Separator => ""],
				[Button => "~Exit", -command => sub{ exit(0); }],
			],
		],
	];
	my $menu = $mw->Menu(-menuitems => $menuitems);
	$mw->configure(-menu => $menu);


	# define & pack your widgets here
	$gui{f_selectors} = $mw->Frame(-bg => 'green')->pack(-fill => 'x');
	$gui{f_selectors}->LabEntry(
		-label=>"Abaqus Materialverzeichnis",
		-labelPack=>[-side=>'right'], -width=>80,
		-text => 'TODO: initial value',
	)->pack(-padx => 20, -pady => 5);
	
	$gui{f_row2} = $mw->Frame(
		-bg => 'yellow'
	)->pack(-fill => 'both', -expand => 1,);
	
	$gui{f_left} = $gui{f_row2}->Frame(
		-bg => 'red',
	)->pack( -side => 'left', -fill => 'both', -expand => 1, );
	
	$gui{f_left}->Label(-text => 'test')->pack();
	
	$gui{f_right} = $gui{f_row2}->Frame(
		-bg => 'blue',
	)->pack( -side => 'right', -fill => 'both', -expand => 1, );
	
} # /_build_gui




=head2 run()

This actually starts the application, including the gui event loop.

=cut

sub run {
	my $self = shift;
	my $mw = $self->get_mw();
	
	$mw->MainLoop();
} # /run
