Implemented Interfaces

GtkTable implements AtkImplementorIface and GtkBuildable.

Includes

#include <gtk/gtk.h>

Description

The GtkTable functions allow the programmer to arrange widgets in rows and columns, making it easy to align many widgets next to each other, horizontally and vertically.

Tables are created with a call to gtk_table_new(), the size of which can later be changed with gtk_table_resize().

Widgets can be added to a table using gtk_table_attach() or the more convenient (but slightly less flexible) gtk_table_attach_defaults().

To alter the space next to a specific row, use gtk_table_set_row_spacing(), and for a column, gtk_table_set_col_spacing().

The gaps between all rows or columns can be changed by calling gtk_table_set_row_spacings() or gtk_table_set_col_spacings() respectively.

gtk_table_set_homogeneous(), can be used to set whether all cells in the table will resize themselves to the size of the largest widget in the table.

Functions

gtk_table_new ()

GtkWidget *
gtk_table_new (guint rows,
               guint columns,
               gboolean homogeneous);

Used to create a new table widget. An initial size must be given by specifying how many rows and columns the table should have, although this can be changed later with gtk_table_resize(). rows and columns must both be in the range 1 .. 65535. For historical reasons, 0 is accepted as well and is silently interpreted as 1.

Parameters

rows	The number of rows the new table should have.
columns	The number of columns the new table should have.
homogeneous	If set to `TRUE`, all table cells are resized to the size of the cell containing the largest widget.

Returns

A pointer to the the newly created table widget.

gtk_table_resize ()

void
gtk_table_resize (GtkTable *table,
                  guint rows,
                  guint columns);

If you need to change a table's size after it has been created, this function allows you to do so.

Parameters

table	The GtkTable you wish to change the size of.
rows	The new number of rows.
columns	The new number of columns.

gtk_table_attach ()

void
gtk_table_attach (GtkTable *table,
                  GtkWidget *child,
                  guint left_attach,
                  guint right_attach,
                  guint top_attach,
                  guint bottom_attach,
                  GtkAttachOptions xoptions,
                  GtkAttachOptions yoptions,
                  guint xpadding,
                  guint ypadding);

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).

Parameters

table	The GtkTable to add a new widget to.
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.

gtk_table_attach_defaults ()

void
gtk_table_attach_defaults (GtkTable *table,
                           GtkWidget *widget,
                           guint left_attach,
                           guint right_attach,
                           guint top_attach,
                           guint bottom_attach);

As there are many options associated with gtk_table_attach(), this convenience function provides the programmer with a means to add children to a table with identical padding and expansion options. The values used for the GtkAttachOptions are GTK_EXPAND | GTK_FILL, and the padding is set to 0.

Parameters

table	The table to add a new child widget to.
widget	The child widget to add.
left_attach	The column number to attach the left side of the child widget to.
right_attach	The column number to attach the right side of the child widget to.
top_attach	The row number to attach the top of the child widget to.
bottom_attach	The row number to attach the bottom of the child widget to.
