NAME ^

Tickit::Widget::GridBox - lay out a set of child widgets in a grid

SYNOPSIS ^

 use Tickit;
 use Tickit::Widget::GridBox;
 use Tickit::Widget::Static;

 my $gridbox = Tickit::Widget::GridBox->new(
    style => {
       col_spacing => 2,
       row_spacing => 1,
    },
    children => [
      [ Tickit::Widget::Static->new( text => "top left" ),
        Tickit::Widget::Static->new( text => "top right" ) ],
      [ Tickit::Widget::Static->new( text => "bottom left" ),
        Tickit::Widget::Static->new( text => "bottom right" ) ],
    ],
 );

 Tickit->new( root => $gridbox )->run;

DESCRIPTION ^

This container widget holds a set of child widgets distributed in a regular grid shape across rows and columns.

STYLE ^

The default style pen is used as the widget pen.

The following style keys are used:

col_spacing => INT

The number of columns of spacing between columns

row_spacing => INT

The number of rows of spacing between rows

CONSTRUCTOR ^

$gridbox = Tickit::Widget::GridBox->new( %args )

Constructs a new Tickit::Widget::GridBox object.

Takes the following named arguments:

children => ARRAY[ARRAY[Tickit::Widget]]

Optional. If present, should be a 2D ARRAYref of ARRAYrefs containing the Tickit::Widget children to display in the grid. They are all added with no additional options.

METHODS ^

$gridbox->add( $row, $col, $child, %opts )

Sets the child widget to display in the given grid cell. Cells do not need to be explicitly constructed; the grid will automatically expand to the size required. This method can also be used to replace an existing child at the given cell location. To remove a cell entirely, use the remove method.

The following options are recognised:

col_expand => INT
row_expand => INT

Values for the expand setting for this column or row of the table. The largest expand setting for any cell in a given column or row sets the value used to distribute space to that column or row.

$gridbox->remove( $row, $col )

Removes the child widget on display in the given cell. May shrink the grid if this was the last child widget in the given row or column.
