Arguments

obj

parent object

child

child widget

expand

NULL or logical. For box containers controls whether a child will expand to fill the allocated space.

fill

NULL or character. For box containers. The value of fill (not always respected) is used to control if expansion happens vertically (y), horizontally (x) or both (both or TRUE). For vertically filled box containers, children always fill horizontally (atleast) and for horizontally filled box containers, children always fill vertically (atleast). This is important to realize when trying to size buttons, say.

anchor

NULL or integer. For box containers. The anchor argument is used to position the child within the parent when there is more space allocated than the child requests. This is specified with a Cartesian pair in -1,0,1 x -1, 0, 1.
