attach_next_to

Description:

public void attach_next_to (Widget child, Widget? sibling, PositionType side, int width = 1, int height = 1)

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:

this	a `GtkGrid`
child	the widget to add
sibling	the child of this 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
