VtRowColumn -- create a RowColumn widget

Synopsis

VtRowColumn widgetName [options]

Creates a RowColumn widget. Returns the widget name. This widget is only used to force its children to be laid out in rows and columns.

-packing NONE | COLUMN | TIGHT (CS)

Sets how items contained in a RowColumn widget are packed.

NONE: No packing is performed. The x and y attributes of each entry are left alone, and the column widget attempts to become large enough to enclose all entries.
COLUMN: All entries are placed in identically sized boxes. The boxes are based on the largest height and width values of all the children widgets. The value of numColumns determines how many boxes are placed in the major dimension, before extending in the minor dimension.
TIGHT: Given the current orientation (horizontal or vertical) entries are placed one after the other until the RowColumn must wrap. A RowColumn will wrap when there is no room left for a complete child in that dimension. Wrapping occurs by beginning a new row or column in the next available space. Wrapping continues as often as necessary, until all of the children are laid out. In the vertical dimension (columns), the boxes are set to the same width; in the horizontal dimension (rows) the boxes are set to the same depth. Each entry's position in the major dimension is left unaltered; its position in the minor dimension is set to the same value as the greatest entry in that particular row or column. The position in the minor dimension of any particular row or column is independent of all other rows or columns.

If VtRowColumn fails, it returns one of the following error messages:
