add: Add a child object to parent container

In gWidgets2: Rewrite of gWidgets API for Simplified GUI Construction

Description

Add packs in child objects.

Delete may or may not remove a child. This is toolkit specific. It may also be tied up with garbage collection. To avoid that, keep a reference to the child object before deleting.

Usage

add(obj, child, expand = FALSE, fill = NULL, anchor = NULL, ...)

## Default S3 method:
add(obj, child, expand = FALSE, fill = NULL, anchor = NULL, ...)

delete(obj, child)

## S3 method for class 'GContainer'
delete(obj, child)

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.
