Class TableLayout

java.lang.Object
  extended by 

org.eclipse.swt.widgets.Layout
      extended by 
org.eclipse.jface.viewers.TableLayout

public class TableLayout
extends 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 TableColumnLayout


Constructor Summary
TableLayout ()
          Creates a new table layout.
 
Method Summary
 void addColumnData ( ColumnLayoutData data)
          Adds a new column of data to this table layout.
  Point computeSize ( Composite c, int wHint, int hHint, boolean flush)
          Computes and returns the size of the specified composite's client area according to this layout.
 void layout ( Composite c, boolean flush)
          Lays out the children of the specified composite according to this layout.

Constructor Detail

TableLayout

public TableLayout()
Creates a new table layout.

Method Detail

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.

Specified by:
computeSize in class Layout
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.

Specified by:
layout in class Layout
Parameters:
c - a composite widget using this layout
flush - true means flush cached layout values
