GI.Gtk.Objects.Grid

GtkGrid is a container which arranges its child widgets in rows and columns. It is a very similar to Table and Box, but it consistently uses Widget’s Widget:margin and Widget:expand properties instead of custom child properties, and it fully supports [height-for-width geometry management][geometry-management].

Children are added using gridAttach. They can span multiple rows or columns. It is also possible to add a child next to an existing child, using gridAttachNextTo. The behaviour of GtkGrid when several children occupy the same grid cell is undefined.

GtkGrid can be used like a Box by just using containerAdd, which will place children next to each other in the direction determined by the Orientable:orientation property.

CSS nodes

GtkGrid uses a single CSS node with name grid.

Methods

attach

gridAttach

Arguments

:: (HasCallStack, MonadIO m, IsGrid a, IsWidget b)

=> a

grid: a Grid

-> b

child: the widget to add

-> Int32

left: the column number to attach the left side of child to

-> Int32

top: the row number to attach the top side of child to

-> Int32

width: the number of columns that child will span

-> Int32

height: the number of rows that child will span

-> m ()

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.

attachNextTo

gridAttachNextTo

Arguments

:: (HasCallStack, MonadIO m, IsGrid a, IsWidget b, IsWidget c)

=> a

grid: a Grid

-> b

child: the widget to add

-> Maybe c

sibling: the child of grid that child will be placed next to, or Nothing to place child at the beginning or end

-> PositionType

side: the side of sibling that child is positioned next to

-> Int32

width: the number of columns that child will span

-> Int32

height: the number of rows that child will span

-> m ()

Adds a widget to the grid.

The widget is placed next to sibling, on the side determined by side. When sibling is Nothing, 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 == Nothing and side == PositionTypeLeft yields a layout of [3][2][1].
