Row and column layout manager

The FXMatrix widget arranges its children in rows and columns.

You can perform the layout row-wise using the default value of the opts argument (MATRIX_BY_ROWS) or column-wise by setting opts=MATRIX_BY_COLUMNS. If you specify opts=MATRIX_BY_ROWS, the matrix will create the specified number of rows and as many columns as are needed to accommodate all its children. Conversely, if you specify opts=MATRIX_BY_COLUMNS, the matrix will create the specified number of columns and as many rows as are needed to accommodate all its children.

For example, using the default opts=MATRIX_BY_ROWS setting, 

m = FXMatrix(parent, 2)
FXButton(m, 'Button 1')
FXButton(m, 'Button 2')
FXButton(m, 'Button 3')
FXButton(m, 'Button 4')
FXButton(m, 'Button 5')
FXButton(m, 'Button 6')
