org.eclipse.jface.wizard
Class WizardDialog.PageContainerFillLayout

java.lang.Object
  org.eclipse.swt.widgets.Layout
      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.

public WizardDialog.PageContainerFillLayout(int mw,
                                            int mh,
                                            int minW,
                                            int minH)

Creates new layout object.

Parameters:

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 minimum size that the client area of the composite must be in order to position all children at their minimum 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 minimum 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 minimum)

hHint - height (SWT.DEFAULT for minimum)

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 layed 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
