setGeometry ?-w win? ?(-c|-d)? {x y w h}
Set the dimensions of a window. The dimensions are specified by a Tcl list of the form {x y w h} where x and y are the x-coord and y-coord of the lower left corner in screen coordinates and w and h are the width and height.
The -c and -d options have the same meaning as with the [getGeometry] command.
