## Implemented Interfaces

GtkGrid implements AtkImplementorIface, GtkBuildable and GtkOrientable.

## Includes

    #include <gtk/gtk.h>

## Description

GtkGrid is a container which arranges its child widgets in rows and columns, with arbitrary positions and horizontal/vertical spans.

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()`. The behaviour of GtkGrid when several children occupy the same grid cell is undefined.

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. However, if all you want is a single row or column, then GtkBox is the preferred widget.

### CSS nodes

GtkGrid uses a single CSS node with name grid.

## Functions

### 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` .

#### Parameters

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 width,
                             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[1].

#### Parameters

grid | a GtkGrid |
child | the widget to add |
sibling | the child of `grid` that `child` will be placed next to, or `NULL` to place `child` at the beginning or end. | [allow-none]
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` .

#### Parameters

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`.

### gtk_grid_insert_row ()

    void
    gtk_grid_insert_row (GtkGrid *grid,
                         gint position);

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.

#### Parameters

grid | a GtkGrid |

Since: 3.2

### gtk_grid_insert_column ()

    void
    gtk_grid_insert_column (GtkGrid *grid,
                            gint position);

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.

#### Parameters

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

Since: 3.2

### gtk_grid_remove_row ()

Removes a row from the grid.

Children that are placed in this row are removed, spanning children that overlap this row have their height reduced by one, and children below the row are moved up.

#### Parameters

grid | a GtkGrid |
position | the position of the row to remove |

Since: 3.10

position | the position of the column to remove |

Since: 3.10

                             GtkPositionType side);

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.

#### Parameters
