Given x and y values in screen units relative to the master window, the column and row number at that x and y location is returned. For locations that are above or to the left of the grid, -1 is returned. If boolean has a false boolean value then propagation is disabled for master . In either of these cases an empty string is returned. If boolean is omitted then the command returns 0 or 1 to indicate whether propagation is currently enabled for master .
Propagation is enabled by default.
Query or set the row properties of the index row of the geometry master, master . The -minsize option sets the minimum size, in screen units, that will be permitted for this row. A row whose weight is two will grow at twice the rate as a row of weight one when extra space is allocated to the layout. The -pad option specifies the number of screen units that will be added to the largest window contained completely in that row when the grid geometry manager requests a size from the containing window. If only an option is specified, with no value, the current value of that option is returned.
