java.lang.Object
  extended by 

org.eclipse.swt.widgets.Layout
      extended by 
org.eclipse.jface.wizard.WizardDialog.PageContainerFillLayout
Enclosing class:
WizardDialog

protected class WizardDialog.PageContainerFillLayout
extends Layout

A layout for a container which includes several pages, like a notebook, wizard, or preference dialog. The size computed by this layout is the maximum width and height of all pages currently inserted into the container.


Field Summary
 int marginHeight
          The margin height; 5 pixels by default.
 int marginWidth
          The margin width; 5 pixels by default.
 int minimumHeight
          The minimum height; 0 pixels by default.
 int minimumWidth
          The minimum width; 0 pixels by default.
 
Constructor Summary
WizardDialog.PageContainerFillLayout (int mw, int mh, int minW, int minH)
          Creates new layout object.
 
Method Summary
  Point computeSize ( Composite composite, int wHint, int hHint, boolean force)
          Computes and returns the size of the specified composite's client area according to this layout.
  Rectangle getClientArea ( Composite c)
          Returns the client area for the given composite according to this layout.
 void layout ( Composite composite, boolean force)
          Lays out the children of the specified composite according to this layout.
 void layoutPage ( Control w)
          Lays outs the page according to this layout.
 void setPageLocation ( Control w)
          Sets the location of the page so that its origin is in the upper left corner.

                                            int mh,
                                            int minW,
                                            int minH)
Creates new layout object.

Parameters:
mw - the margin width
mh - the margin height
minW - the minimum width
minH - the minimum height
Method Detail

computeSize

public 
Point computeSize(
Composite composite,
                         int wHint,
                         int hHint,
                         boolean force)
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:
composite - a composite widget using this layout
wHint - width (SWT.DEFAULT for preferred size)
hHint - height (SWT.DEFAULT for preferred size)
force - true means flush cached layout values
Returns:
a point containing the computed size (width, height)

getClientArea

public 
Rectangle getClientArea(
Composite c)
Returns the client area for the given composite according to this layout.

Parameters:
c - the composite
Returns:
the client area rectangle

layout

public void layout(
Composite composite,
                   boolean force)
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:
composite - a composite widget using this layout
force - true means flush cached layout values

layoutPage

public void layoutPage(
Control w)
Lays outs the page according to this layout.

Parameters:
w - the control

setPageLocation

public void setPageLocation(
Control w)
Sets the location of the page so that its origin is in the upper left corner.

Parameters:
w - the control
