Constructor Detail

ScrollableHolder

public ScrollableHolder(Control holding)

Method Detail

getSubControls

public Iterator getSubControls()

Overrides:

getSubControls in class Control

getClientConstraints

public int getClientConstraints()

This returns the clientConstraints, which will be any of the HEXPAND, HCONTRACT, VEXPAND, VCONTRACT values ORed together. By default it is HEXPAND|VEXPAND meaning the client will be expanded bigger than its preferred size, but will not be contracted smaller than its preferred size.

setClientConstraints

public void setClientConstraints(boolean hExpand,
                                 boolean hContract,
                                 boolean vExpand,
                                 boolean vContract)

Set the clientConstraints value specifying the behavior horizontally and vertically.

Parameters:

hExpand - if this is true then the client control will be expanded horizontally.

hContract - if this is true then the client control will be contracted horizontally.

vExpand - if this is true then the client control will be expanded vertically.

vContract - if this is true then the client control will be contracted vertically.

setClientConstraints

public void setClientConstraints(int constraints)

Set the clientConstraints value specifying the behavior horizontally and vertically.

Parameters:

constraints - any of the HEXPAND, HCONTRACT, VEXPAND, VCONTRACT values ORed together.

needScrollBar

public boolean needScrollBar(int which,
                             int visible)

Specified by:

needScrollBar in interface ScrollClient

Overrides:

needScrollBar in class Canvas

canGo

public boolean canGo(int orientation,
                     int direction,
                     int position)

Specified by:

canGo in interface ScrollClient

Overrides:

canGo in class Canvas

dismantle

public void dismantle(Control downTo)

Overrides:

dismantle in class Container

make

public void make(boolean remake)

Description copied from class: Control

This is used to "make" the control before being displayed. This is usually only overridden by containers.

Overrides:

make in class Control

Parameters:

remake - if this is true then you should do a full re-make.

changeContents

public void changeContents(Control what)

onSetOrigin

public void onSetOrigin()

Overrides:

onSetOrigin in class Canvas

resizeTo

public void resizeTo(int w,
                     int h)

Description copied from class: Control

This will change the width and height values.

Overrides:

resizeTo in class Control

calculateSizes

protected void calculateSizes()

Description copied from class: Control

Override this to calculate the preferred, minimum and maximum size of your control. This is only called once unless the modifier flag AlwaysRecalculateSizes is true. During the calculation you will set the variables preferredWidth, preferredHeight, etc. directly.

Overrides:

calculateSizes in class Control

doPaint

public void doPaint(Graphics g,
                    Rect where)

Overrides:

doPaint in class Control
