public class TableLayout

Layout
A layout for a table. Call addColumnData to add columns.
The TableLayout
ColumnLayoutData is only valid until the table
is resized. To keep the proportions constant when the table is resized
see

TableLayout
public TableLayout()
- Creates a new table layout.
addColumnData
public void addColumnData(
ColumnLayoutData data)
- Adds a new column of data to this table layout.

-
Parameters:
-
data - the column layout data
computeSize
public
Point computeSize(
Composite c,
int wHint,
int hHint,
boolean flush)

Description copied from class:
Layout
- Computes and returns the size of the specified
composite's client area according to this layout.
This method computes the size that the client area
of the composite must be in order to position all
children at their preferred size inside the
composite according to the layout algorithm
encoded by this layout.
When a width or height hint is supplied, it is
used to constrain the result. For example, if a
width hint is provided that is less than the
width of the client area, the layout may choose
to wrap and increase height, clip, overlap, or
otherwise constrain the children.

-
Parameters:
-
c - a composite widget using this layout -
wHint - width (SWT.DEFAULT for preferred size) -
hHint - height (SWT.DEFAULT for preferred size) -
flush - true means flush cached layout values
-
Returns:
- a point containing the computed size (width, height)

layout
public void layout(
Composite c,
boolean flush)
-
Description copied from class:
Layout
- Lays out the children of the specified composite
according to this layout.
This method positions and sizes the children of a
composite using the layout algorithm encoded by this
layout. Children of the composite are positioned in
the client area of the composite. The position of
the composite is not altered by this method.
When the flush cache hint is true, the layout is
instructed to flush any cached values associated
with the children. Typically, a layout will cache
the preferred sizes of the children to avoid the
expense of computing these values each time the
widget is laid out.
When layout is triggered explicitly by the programmer
the flush cache hint is true. When layout is triggered
by a resize, either caused by the programmer or by the
user, the hint is false.
