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.

Details

GtkTable

typedef struct _GtkTable GtkTable;

The GtkTable structure holds the data for the actual table itself. children is a GList of all the widgets the table contains. rows and columns are pointers to GtkTableRowCol structures, which contain the default spacing and expansion details for the GtkTable's rows and columns, respectively.

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


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 0 .. 65535.

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.

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).

table :

The GtkTable to add a new widget to.

child :

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.

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.
