GtkAlignment
A container that controls the alignment and size of it's child.
Object Hierarchy
Description
The GtkAlignment container controls the alignment
and size of it's child, relative to it's own dimensions. However, if the
child has a size request from it's own child/children, it will take
precedence. For example, a GtkButton with a label
will never be scaled down to a size smaller than that of the label.
It can be used to define the relative alignment of the child
within the container, through the
xalign and yalign parameters.
Both can vary between 0 and 1, meaning left/top and right/bottom, respectively.
This is very useful, for instance in left- or right-aligning GtkLabels.
Another use for GtkAlignment (through
xscale and yscale), is to
indicate the ammount of extra free space in the container the child should
be extended to occupy. Note that this isn't the same as total size of the
child widget.
GtkAlignment also provides methods to specifically
set (and retrieve the current) top, bottom, right and left padding of the widget.
