METHODS

new

    use Grid::Layout;

    my $gl = Grid::Layout->new();

_init_V_or_H

    $self->_init_V_or_H('V');
    $self->_init_V_or_H('H');

This method is called by "new" twice to initialize the vertical and the horizontal components of the layout.

The parameter 'V' or 'H' indiciates which componenents to initialize.

add_vertical_track

add_horizontal_track

_add_track

_add_line

    $self->_add_line($V_or_H);

Internal function, called by "_add_track", to add a vertical or horizontal Grid::Layout::Line.

area

    my $vertical_track_from   = $gl->add_vertical_track(…);
    my $horizontal_track_from = $gl->add_vertical_track(…);

    my $vertical_track_to     = $gl->add_vertical_track(…);
    my $horizontal_track_to   = $gl->add_vertical_track(…);

    my $area = $gl->area($vertical_track_from, $horizontal_track_from, $vertical_track_to, $vertical_track_to);

Define an Area bound by the four Tracks;

size_x

    my $x = $gl->size_x();

Returns the horizontal size (x axis) in logical cell units.

size_y

    my $y = $gl->size_y();

Returns the vertical size (y axis) in logical cell units.

size

Returns size of grid (nof vertical tracks x nof horizontal tracks);

    my ($v, $h) = $gl -> size();

_size

Internal use.

cell

    my $track_v = $gl->add_vertical_track(…);
    my $track_h = $gl->add_horizontal_track(…);

    my $cell_1 = $gl->cell($x, $y);
    my $cell_2 = $gl->cell($track_v, $track_h);

Return the Grid::Layout::Cell at horizontal position $x and vertical position $y or where $track_v and $track_h intersects.

_add_cell

Internal use.

line_x

    my $line = $gl->line_x($postition);

Returns the $positionth line in horizontal direction.

line_y

    my $line = $gl->line_y($postition);

Returns the $positionth line in vertical direction.

_line

    my $line = $gl->_line($V_or_H, $position)

Returns the $positionth line in vertical or horizontal direction.

VH_opposite

    my $o1 = Grid::Layout::VH_opposite('H');
    my $02 = Grid::Layout::VH_opposite('V');

Static method. Returns 'V' if passed 'H' and vice versa.
