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() [1/5]

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

Initializes a new view object that is a child of another view.

Parameters

parent	The parent view.
size	The initial location and size of the view, in the coordinate system of parent.
visible	Can be set to IlFalse to initially hide the window.

IlvElasticView() [2/5]

IlvElasticView::IlvElasticView	(	IlvDisplay *	display,
		IlvSystemView	available
	)

Initializes a new new view object by actually using an existing system view.

Parameters

display	The display instance.
available	The system view on which this IlvElasticView is based.

IlvElasticView() [3/5]

IlvElasticView::IlvElasticView	(	IlvDisplay *	display,
		IlvSystemView	parent,
		const IlvRect &	size,
		IlBoolean	visible = IlTrue
	)

Initializes a new view that is a child of an existing system view.

Parameters

display	The display instance.
parent	The parent system view.
size	The initial location and size of the view, in the coordinate system of the existing system view.
visible	Can be set to IlFalse to initially hide the window.

IlvElasticView() [4/5]

IlvElasticView::IlvElasticView	(	IlvDisplay *	display,
		const char *	name,
		const char *	title,
		const IlvRect &	size,
		IlBoolean	visible = IlTrue
	)

Initializes initializes a new view object that is a new top window.

Parameters

display	The display instance.
name	The name of this view (used by the resource association mechanism).
title	The title of this top window.
size	The initial location and size of the view, relative to the root window of display.
visible	Can be set to IlFalse to initially hide the window.

IlvElasticView() [5/5]

IlvElasticView::IlvElasticView	(	IlvDisplay *	display,
		const char *	name,
		const char *	title,
		const IlvRect &	dims,
		IlUInt	properties,
		IlBoolean	visible = IlTrue,

	)

Initializes initializes a new view object that is a new top window with specific top-window properties.

Parameters

display	The display instance.
name	The name of this view (used by the resource association mechanism).
title	The title of this top window.
dims	The initial location and size of the view, relative to the root window of display.
properties	The properties of that view. Check the similar parameter of the similar constructor for the class IlvView for details.
visible	Can be set to IlFalse to initially hide the window.
transientFor	The possible system view for which this view is transient. If unspecified or set to 0, this view will not be transient for any view.
