## Description

GtkGrid is a container which arranges its child widgets in rows and columns. It is a very similar to GtkTable and GtkBox, but it consistently uses GtkWidget's "margin" and "expand" properties instead of custom child properties, and it fully supports height-for-width geometry management.

Children are added using `gtk_grid_attach()`. They can span multiple rows or columns. It is also possible to add a child next to an existing child, using `gtk_grid_attach_next_to()`.

GtkGrid can be used like a GtkBox by just using `gtk_container_add()`, which will place children next to each other in the direction determined by the "orientation" property.

## Details

### struct GtkGrid

    struct GtkGrid;

### gtk_grid_new ()

    GtkWidget *         gtk_grid_new                        (void);

Creates a new grid widget.

Returns : | the new GtkGrid

### gtk_grid_attach ()

    void                gtk_grid_attach                     (GtkGrid *grid,
                                                             GtkWidget *child,
                                                             gint left,
                                                             gint top,
                                                             gint width,
                                                             gint height);

Adds a widget to the grid.

The position of `child` is determined by `left` and `top`. The number of 'cells' that `child` will occupy is determined by `width` and `height`.

`grid` : | a GtkGrid
`child` : | the widget to add
`left` : | the column number to attach the left side of `child` to
`top` : | the row number to attach the top side of `child` to
`width` : | the number of columns that `child` will span
`height` : | the number of rows that `child` will span

### gtk_grid_attach_next_to ()

    void                gtk_grid_attach_next_to             (GtkGrid *grid,
                                                             GtkWidget *child,
                                                             GtkWidget *sibling,
                                                             GtkPositionType side,

                                                             gint height);

Adds a widget to the grid.

The widget is placed next to `sibling`, on the side determined by `side`. When `sibling` is `NULL`, the widget is placed in row (for left or right placement) or column 0 (for top or bottom placement), at the end indicated by `side`.

Attaching widgets labeled [1], [2], [3] with `sibling` == `NULL` and `side` == `GTK_POS_LEFT` yields a layout of [3][2][1].

`grid` : | a GtkGrid
`child` : | the widget to add `sibling` (allow-none): the child of `grid` that `child` will be placed next to, or `NULL` to place `child` at the beginning or end
`side` : | the side of `sibling` that `child` is positioned next to
`width` : | the number of columns that `child` will span
`height` : | the number of rows that `child` will span

### gtk_grid_get_child_at ()

    GtkWidget *         gtk_grid_get_child_at               (GtkGrid *grid,
                                                             gint left,
                                                             gint top);

Gets the child of `grid` whose area covers the grid cell whose upper left corner is at `left`, `top`.

`grid` : | a GtkGrid
`left` : | the left edge of the cell
`top` : | the top edge of the cell
Returns : | the child at the given position, or `NULL`

Since 3.2

Inserts a row at the specified position.

Children which are attached at or below this position are moved one row down. Children which span across this position are grown to span the new row.

`grid` : | a GtkGrid
`position` : | the position to insert the row at

Since 3.2

### gtk_grid_insert_column ()

Inserts a column at the specified position.

Children which are attached at or to the right of this position are moved one column to the right. Children which span across this position are grown to span the new column.

`grid` : | a GtkGrid
`position` : | the position to insert the column at

Since 3.2

### gtk_grid_insert_next_to ()

    void                gtk_grid_insert_next_to             (GtkGrid *grid,

Inserts a row or column at the specified position.

The new row or column is placed next to `sibling`, on the side determined by `side`. If `side` is `GTK_POS_TOP` or `GTK_POS_BOTTOM`, a row is inserted. If `side` is `GTK_POS_LEFT` of `GTK_POS_RIGHT`, a column is inserted.

`grid` : | a GtkGrid
`sibling` : | the child of `grid` that the new row or column will be placed next to
`side` : | the side of `sibling` that `child` is positioned next to
