## Detailed Description

Pack widgets in regular patterns.

Gtk::Table is one of the primary ways of grouping widgets together. It consists of a set of lattice points to to which widgets can be attached. There are rows + 1 lattice points vertically and columns + 1 lattice points horizontally. Lattice points start counting from 0. Lattice points can either be specified to be homogeneous, meaning equally spaced, or not homogeneous, meaning each cell should be calculated based on the widgets contained in the row and column. The homogeneous property defaults to false.

Widgets can be attached to the table by specifying the top, bottom, left and right points corresponding to upper, lefthand lattice point and the lower, righthand lattice point which the widget should span. Widgets can either be contained in a cell or may span cells. A number of options control the resizing behavior of widgets contained in the table.

Packing options:
  There are a number of packing options that can be specified when adding a widget. With `Gtk::EXPAND`, the lattice is allowed to grow to fill space. With `Gtk::SHRINK`, the lattice is allowed to shrink when resized. It is also possible to specify the behaviour of the widgets allocation within the table. The flag `Gtk::FILL` declares the widget should grow to fill lattice. If this is not set any extra space is used as padding. The default is `(Gtk::FILL | Gtk::EXPAND)`.

Table sizing:
  The table size is calculated based on the size of the widgets contained within and the restrictions imposed by specified options. Padding and spacing can be used in the table. Padding is added on either side of a widget, while spacing is placed between widgets.

A Table widget looks like this:

## Constructor & Destructor Documentation

virtual Gtk::Table::~Table | ( |  | ) | `[virtual]`

Gtk::Table::Table | ( | guint | n_rows = `1`,
|  | guint | n_columns = `1`,
|  | bool | homogeneous = `false`
| ) |  | `[explicit]`

## Member Function Documentation

void Gtk::Table::attach | ( | Widget& | child,
|  | guint | left_attach,
|  | guint | right_attach,
|  | guint | top_attach,
|  | guint | bottom_attach,
|  | AttachOptions | xoptions = `FILL|EXPAND`,
|  | AttachOptions | yoptions = `FILL|EXPAND`,
|  | guint | xpadding = `0`,
|  | guint | ypadding = `0`
| ) |  |

Adds a widget to a table.

The number of 'cells' that a widget will occupy is specified by left_attach, right_attach, top_attach and bottom_attach. These each represent the leftmost, rightmost, uppermost and lowest column and row numbers of the table. (Columns and rows are indexed from zero).

To make a button occupy the lower right cell of a 2x2 table, use

     gtk_table_attach (table, button,
     1, 2, // left, right attach
     1, 2, // top, bottom attach
     xoptions, yoptions,
     xpadding, ypadding);

If you want to make the button span the entire bottom row, use left_attach == 0 and right_attach = 2 instead.

Parameters:

  child | The widget to add.
  left_attach | The column number to attach the left side of a child widget to.
  right_attach | The column number to attach the right side of a child widget to.
  top_attach | The row number to attach the top of a child widget to.
  bottom_attach | The row number to attach the bottom of a child widget to.
  xoptions | Used to specify the properties of the child widget when the table is resized.
  yoptions | The same as xoptions, except this field determines behaviour of vertical resizing.
  xpadding | An integer value specifying the padding on the left and right of the widget being added to the table.
  ypadding | The amount of padding above and below the child widget.
