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
