properties: Equal Width and Num Columns . The first indicates whether the
columns in the grid are of equal width. The second determines the number of
columns. When figures are added to a grid layout, they are laid out in columns,
with new rows being added when this number is met.
Grid Layout Data elements have a number of properties, summarized in
Table 11-5.

Table 11-5 Grid Layout Properties

Property Values Description

Grab Excess true | false Determines whether the cell should be widened

Horizontal Space to fit the remaining space. Default is false.

Grab Excess true | false Determines whether the cell should be made tall

Vertical Space enough to fit the remaining space. Default is

false.

Horizontal BEGINNING | Determines how a figure is positioned

Alignment CENTER | END | horizontally within a cell. Default is CENTER.

FILL Note that in horizontal alignment,

BEGINNING is LEFT and END is RIGHT.
FILL resizes the figure.

Horizontal Indent Integer Specifies the number of pixels of indentation on

the left side of the cell. Default is 0.

Horizontal Span Integer Specifies the number of column cells that the

figure will occupy. Default is 1.

Vertical Alignment BEGINNING | Determines how a figure is positioned vertically

CENTER | END | within a cell. Default is CENTER. Note that in

FILL vertical alignment, BEGINNING is TOP and

END is BOTTOM. FILL resizes the figure.

Vertical Span Integer Determines the number of row cells that the fig-

ure will occupy. Default is 1.

Figure 11-6 is an example of using Grid Layout to arrange figures within
a rectangle.
In this example, four figures are arranged using grid data elements within a
rectangle that uses grid layout settings equal width = true , number of
columns = 2 , as follows:

The hollow circle uses horizontal and vertical alignment of END , with hor-
izontal span = 2 . As you can see, it's situated at the bottom right of the
top row.
