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.
|
|
</para>
|
|
<para>
|
|
Tables are created with a call to gtk_table_new(), the size of which can
|
|
later be changed with gtk_table_resize().
|
|
</para>
|
|
<para>
|
|
Widgets can be added to a table using gtk_table_attach() or the more
|
|
convenient (but slightly less flexible) gtk_table_attach_defaults().
|
|
</para>
|
|
<para>
|
|
To alter the space next to a specific row, use gtk_table_set_row_spacing(),
|
|
and for a column, gtk_table_set_col_spacing().</para>
|
|
<para>
|
|
The gaps between <emphasis>all</emphasis> rows or columns can be changed by
|
|
calling gtk_table_set_row_spacings() or gtk_table_set_col_spacings()
|
|
respectively. Note that spacing is added <emphasis>between</emphasis> the
|
|
children, while padding added by gtk_table_atach() is added <emphasis>on
|
|
either side</emphasis> of the widget it belongs to.
|
|
</para>
|
|
<para>
|
|
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.

</para>

<note>

<para>
|

Note that #GtkGrid provides the same capabilities as GtkTable for arranging
|
|
widgets in a rectangular grid, and additionally supports height-for-width
|
|
geometry management.

The <structname>GtkTable</structname> structure holds the data for the actual table itself.

<structfield>children</structfield> is a #GList of all the widgets the table contains. <structfield>rows</structfield> and <structfield>columns</structfield> are pointers to #GtkTableRowCol structures, which contain the default spacing and expansion details for the #GtkTable's rows and columns, respectively.
|

</para>

<para>

<structfield>nrows</structfield> and <structfield>ncols</structfield> are 16bit integers storing the number of rows and columns the table has.

<!-- ##### FUNCTION gtk_table_new ##### -->
|
|
<para>
|
|
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.
|
|
</para>
|
|
|
|
@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.
|
|
|
|
|
|
<!-- ##### FUNCTION gtk_table_resize ##### -->

<para>

If you need to change a table's size <emphasis>after</emphasis> it has been created, this function allows you to do so.
|
|
</para>
|
|
|
|
@table: The #GtkTable you wish to change the size of.

@rows: The new number of rows.

<!-- ##### FUNCTION gtk_table_attach ##### -->
|
|
<para>
|
|
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).
|
|
</para>
|
|
<para>
|
|
To make a button occupy the lower right cell of a 2x2 table, use
|
|
<informalexample><programlisting>
|
|
gtk_table_attach (table, button,
|
|
1, 2, /* left, right attach */
|
|
1, 2, /* top, bottom attach */
|
|
xoptions, yoptions,
|
|
xpadding, ypadding);
|
|
</programlisting></informalexample>
|
|
If you want to make the button span the entire bottom row, use @left_attach == 0 and @right_attach = 2 instead.
|
|
</para>
|
|
|
|
@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.
|
|
|
|
|
|
<!-- ##### FUNCTION gtk_table_attach_defaults ##### -->
|
|
<para>
|
|
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 <literal>GTK_EXPAND | GTK_FILL</literal>, and the padding is set to 0.
|
|
