Detailed Description

View class.

Library: xviews or winviews or mviews (mutually exclusive)

This class is like IlvView except that when instances of this class are resized, they automatically resize their child views in an elastic-like manner. You thus use this class when you want a view containing other views that are automatically resized. The first kind of lower-level view inside the top-level view is typically an elastic view so as to handle the consequences of any resizing of the top-level view.

When an elastic view is resized, the size change is transmitted proportionately to the lower-level views inside the elastic view.

Constructor & Destructor Documentation

IlvElasticView::IlvElasticView ( IlvAbstractView parent,
const IlvRect size,
IlBoolean  visible = IlTrue 
)

Constructor.

This constructor initializes a view object that is a child of the parent view.

Parameters
parentThe parent view.
sizeThe initial location and size of the view, in the coordinate system of parent.
visibleCan be set to IlFalse to initially hide the window.
IlvElasticView::IlvElasticView ( IlvDisplay display,
IlvSystemView  available 
)

Constructor.

This constructor creates a new view object by actually using the existing system view indicated by available.

Parameters
displayThe display instance.
availableThe system view on which this IlvView is based.
IlvElasticView::IlvElasticView ( IlvDisplay display,
IlvSystemView  parent,
const IlvRect size,
IlBoolean  visible = IlTrue 
)

Constructor.

This constructor creates a view that is a child of the existing system view indicated by parent.

Parameters
displayThe display instance.
parentThe parent system view.
sizeThe initial location and size of the view, in the coordinate system of the existing system view.
visibleCan be set to IlFalse to initially hide the window.
IlvElasticView::IlvElasticView ( IlvDisplay display,
const char *  name,
const char *  title,
const IlvRect size,
IlBoolean  visible = IlTrue 
)

Constructor.

This constructor initializes a view object that is a new top window.

Parameters
displayThe display instance.
nameThe name of this view (used by the resource association mechanism).
titleThe title of this top window.
sizeThe initial location and size of the view, relative to the root window of display.
visibleCan be set to IlFalse to initially hide the window.
IlvElasticView::IlvElasticView ( IlvDisplay display,
const char *  name,
const char *  title,
const IlvRect dims,
IlUInt  properties,
IlBoolean  visible = IlTrue,
IlvSystemView  transientFor = 0 
)

Constructor.

This constructor creates a top window, with an optional parameter properties that makes it possible to tune its aspect. Check the similar constructor of the class IlvView for details.

Parameters
displayThe display instance.
nameThe name of this view (used by the resource association mechanism).
titleThe title of this top window.
dimsThe initial location and size of the view, relative to the root window of display.
propertiesThe properties of that view.
visibleCan be set to IlFalse to initially hide the window.
transientForThe possible system view for which this view is transient. If unspecified or set to 0, this view will not be transient for any view.

Member Function Documentation

virtual void IlvElasticView::moveResize ( const IlvRect newSize)

virtual void IlvElasticView::resize ( IlvDim  w,
IlvDim  h 
)
virtual

Resizes the view.

Parameters
wThe new width of the view.
hThe new height of the view.

Reimplemented from IlvView.
