Detailed Description

A GUI widget that lays out child-widgets in a grid with variable sized cells.

The grid widget lays out child widgets in a grid pattern. Each child widget occupies a single cell, which belongs into a single column and a single row.

Columns are laid out from left to right, and rows from top to bottom. The row and columns number may be specified as integers, or using an spreadsheet-like cell-address:

The grid widget will calculate the size of each row and column based on the minimum, preferred and maximum size of each child widget contained in them. Margins are also taken into account in the spacing between columns and between rows.

When laid out, each child is sized to where it will occupy the full width and height of each cell.
