9 The #GtkTable functions allow the programmer to arrange widgets in rows and
10 columns, making it easy to align many widgets next to each other,
11 horizontally and vertically.
14 Tables are created with a call to gtk_table_new(), the size of which can
15 later be changed with gtk_table_resize().
18 Widgets can be added to a table using gtk_table_attach() or the more
19 convenient (but slightly less flexible) gtk_table_attach_defaults().
22 To alter the space next to a specific row, use gtk_table_set_row_spacing(),
23 and for a column, gtk_table_set_col_spacing().</para>
25 The gaps between <emphasis>all</emphasis> rows or columns can be changed by
26 calling gtk_table_set_row_spacings() or gtk_table_set_col_spacings()
27 respectively. Note that spacing is added <emphasis>between</emphasis> the
28 children, while padding added by gtk_table_atach() is added <emphasis>on
29 either side</emphasis> of the widget it belongs to.
32 gtk_table_set_homogeneous(), can be used to set whether all cells in the
33 table will resize themselves to the size of the largest widget in the table.
37 Note that #GtkGrid provides the same capabilities as GtkTable for arranging
38 widgets in a rectangular grid, and additionally supports height-for-width

63 <!-- ##### STRUCT GtkTable ##### -->
65 The <structname>GtkTable</structname> structure holds the data for the actual table itself.
67 <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.
70 <structfield>nrows</structfield> and <structfield>ncols</structfield> are 16bit integers storing the number of rows and columns the table has.

139 <!-- ##### FUNCTION gtk_table_new ##### -->
141 Used to create a new table widget. An initial size must be given by
142 specifying how many rows and columns the table should have, although
143 this can be changed later with gtk_table_resize(). @rows and @columns
144 must both be in the range 1 .. 65535. For historical reasons, 0 is accepted
145 as well and is silently interpreted as 1.
148 @rows: The number of rows the new table should have.
149 @columns: The number of columns the new table should have.
150 @homogeneous: If set to %TRUE, all table cells are resized to the size of the cell
151 containing the largest widget.
152 @Returns: A pointer to the the newly created table widget.
155 <!-- ##### FUNCTION gtk_table_resize ##### -->
157 If you need to change a table's size <emphasis>after</emphasis> it has been created, this function allows you to do so.
160 @table: The #GtkTable you wish to change the size of.
161 @rows: The new number of rows.
162 @columns: The new number of columns.
165 <!-- ##### FUNCTION gtk_table_get_size ##### -->
175 <!-- ##### FUNCTION gtk_table_attach ##### -->
177 Adds a widget to a table. The number of 'cells' that a widget will occupy is
178 specified by @left_attach, @right_attach, @top_attach and @bottom_attach.
179 These each represent the leftmost, rightmost, uppermost and lowest column
180 and row numbers of the table. (Columns and rows are indexed from zero).
183 To make a button occupy the lower right cell of a 2x2 table, use
184 <informalexample><programlisting>
185 gtk_table_attach (table, button,
186 1, 2, /* left, right attach */
187 1, 2, /* top, bottom attach */
190 </programlisting></informalexample>
191 If you want to make the button span the entire bottom row, use @left_attach == 0 and @right_attach = 2 instead.
194 @table: The #GtkTable to add a new widget to.
195 @child: The widget to add.
196 @left_attach: the column number to attach the left side of a child widget to.
197 @right_attach: the column number to attach the right side of a child widget to.
198 @top_attach: the row number to attach the top of a child widget to.
199 @bottom_attach: the row number to attach the bottom of a child widget to.
200 @xoptions: Used to specify the properties of the child widget when the table is resized.
201 @yoptions: The same as xoptions, except this field determines behaviour of vertical resizing.
202 @xpadding: An integer value specifying the padding on the left and right of the widget being added to the table.
203 @ypadding: The amount of padding above and below the child widget.
206 <!-- ##### FUNCTION gtk_table_attach_defaults ##### -->
208 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.
211 @table: The table to add a new child widget to.
212 @widget: The child widget to add.
213 @left_attach: The column number to attach the left side of the child widget to.
214 @right_attach: The column number to attach the right side of the child widget to.
215 @top_attach: The row number to attach the top of the child widget to.
216 @bottom_attach: The row number to attach the bottom of the child widget to.
219 <!-- ##### FUNCTION gtk_table_set_row_spacing ##### -->
221 Changes the space between a given table row and the subsequent row.
224 @table: a #GtkTable containing the row whose properties you wish to change.
225 @row: row number whose spacing will be changed.
226 @spacing: number of pixels that the spacing should take up.
229 <!-- ##### FUNCTION gtk_table_set_col_spacing ##### -->
231 Alters the amount of space between a given table column and the following
236 @column: the column whose spacing should be changed.
237 @spacing: number of pixels that the spacing should take up.
240 <!-- ##### FUNCTION gtk_table_set_row_spacings ##### -->
242 Sets the space between every row in @table equal to @spacing.
246 @spacing: the number of pixels of space to place between every row in the table.
249 <!-- ##### FUNCTION gtk_table_set_col_spacings ##### -->
251 Sets the space between every column in @table equal to @spacing.
255 @spacing: the number of pixels of space to place between every column in the table.
258 <!-- ##### FUNCTION gtk_table_set_homogeneous ##### -->
260 Changes the homogenous property of table cells, ie. whether all cells are an equal size or not.
263 @table: The #GtkTable you wish to set the homogeneous properties of.
264 @homogeneous: Set to %TRUE to ensure all table cells are the same size. Set
265 to %FALSE if this is not your desired behaviour.
