FUNCTION

Indicate number of columns in a two dimensional group. If you use this tag, the total number of children must be dividable by the number of columns.

The children will be positioned in a two dimensional array, e.g. allowing easy creation of button fields (maybe for calculator).

The children in your taglist are always read line by line.

When MUI layouts two-dimensional groups, it does actually two layout calculations, one for the rows and one the columns. Parameters like weights and dimensions are handled this way:

the minimum width of a column/row is the maximum minimum width of all objects in this column/row.
the maximum width of a column/row is the minimum maximum width of all objects in this column/row.
the weight of a column/row is the sum of all objects in this column/row.

Actually, there is no difference if you use MUIA_Group_Columns or MUIA_Group_Rows.
