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 calling
26 gtk_table_set_row_spacings() or gtk_table_set_col_spacings() respectively.
29 gtk_table_set_homogeneous(), can be used to set whether all cells in the
30 table will resize themselves to the size of the largest widget in the table.

53 <!-- ##### STRUCT GtkTable ##### -->
55 The <structname>GtkTable</structname> structure holds the data for the actual table itself.
57 <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.
60 <structfield>nrows</structfield> and <structfield>ncols</structfield> are 16bit integers storing the number of rows and columns the table has.

129 <!-- ##### FUNCTION gtk_table_new ##### -->
131 Used to create a new table widget. An initial size must be given by
132 specifying how many rows and columns the table should have, although
133 this can be changed later with gtk_table_resize(). @rows and @columns
134 must both be in the range 0 .. 65535.
137 @rows: The number of rows the new table should have.
138 @columns: The number of columns the new table should have.
139 @homogeneous: If set to %TRUE, all table cells are resized to the size of the cell
140 containing the largest widget.
141 @Returns: A pointer to the the newly created table widget.
144 <!-- ##### FUNCTION gtk_table_resize ##### -->
146 If you need to change a table's size <emphasis>after</emphasis> it has been created, this function allows you to do so.
149 @table: The #GtkTable you wish to change the size of.
150 @rows: The new number of rows.
151 @columns: The new number of columns.
154 <!-- ##### FUNCTION gtk_table_attach ##### -->
156 Adds a widget to a table. The number of 'cells' that a widget will occupy is
157 specified by @left_attach, @right_attach, @top_attach and @bottom_attach.
158 These each represent the leftmost, rightmost, uppermost and lowest column
159 and row numbers of the table. (Columns and rows are indexed from zero).
162 @table: The #GtkTable to add a new widget to.
163 @child: The widget to add.
164 @left_attach: the column number to attach the left side of a child widget to.
165 @right_attach: the column number to attach the right side of a child widget to.
166 @top_attach: the row number to attach the top of a child widget to.
167 @bottom_attach: the row number to attach the bottom of a child widget to.
168 @xoptions: Used to specify the properties of the child widget when the table is resized.
169 @yoptions: The same as xoptions, except this field determines behaviour of vertical resizing.
170 @xpadding: An integer value specifying the padding on the left and right of the widget being added to the table.
171 @ypadding: The amount of padding above and below the child widget.
174 <!-- ##### FUNCTION gtk_table_attach_defaults ##### -->
176 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.
179 @table: The table to add a new child widget to.
180 @widget: The child widget to add.
181 @left_attach: The column number to attach the left side of the child widget to.
182 @right_attach: The column number to attach the right side of the child widget to.
183 @top_attach: The row number to attach the top of the child widget to.
184 @bottom_attach: The row number to attach the bottom of the child widget to.
187 <!-- ##### FUNCTION gtk_table_set_row_spacing ##### -->
189 Changes the space between a given table row and the subsequent row.
192 @table: a #GtkTable containing the row whose properties you wish to change.
193 @row: row number whose spacing will be changed.
194 @spacing: number of pixels that the spacing should take up.
197 <!-- ##### FUNCTION gtk_table_set_col_spacing ##### -->
199 Alters the amount of space between a given table column and the following
204 @column: the column whose spacing should be changed.
205 @spacing: number of pixels that the spacing should take up.
208 <!-- ##### FUNCTION gtk_table_set_row_spacings ##### -->
210 Sets the space between every row in @table equal to @spacing.
214 @spacing: the number of pixels of space to place between every row in the table.
217 <!-- ##### FUNCTION gtk_table_set_col_spacings ##### -->
219 Sets the space between every column in @table equal to @spacing.
223 @spacing: the number of pixels of space to place between every column in the table.
226 <!-- ##### FUNCTION gtk_table_set_homogeneous ##### -->
228 Changes the homogenous property of table cells, ie. whether all cells are an equal size or not.
231 @table: The #GtkTable you wish to set the homogeneous properties of.
232 @homogeneous: Set to %TRUE to ensure all table cells are the same size. Set
233 to %FALSE if this is not your desired behaviour.
