Detailed Description

Graphic class.

Library: views
This class enables you to access palette attributes. Every IlvSimpleGraphic has an IlvPalette object, but these palettes are shared between objects. When you ask an IlvSimpleGraphic object to change a graphic property such as its foreground, the following operations are performed:

The getPalette() function is used to search for a new IlvPalette using the graphic properties of the object.
The lock() function is called for the new palette to increment its reference count (see IlvResource::lock()).
The member function unLock() is called for the old palette (see IlvResource::unLock()). li>The new palette is registered as the current palette for the object.

These operations guarantee the sharing of the IlvPalette. Users are encouraged to use the same mechanism in the case of IlvPalette objects. This is why member functions that can manipulate resources by changing the graphic attributes, such as IlvPalette::setForeground(), are defined as virtual functions.

See also: IlvDisplay, IlvPalette.

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclass IlvGraphic and adds the following ones:

Name	Type	Equivalent methods
`foreground`	Color	`getForeground()`, `setForeground()`
`background`	Color	`getBackground()`, `setBackground()`
`font`	Font	`getFont()`, `setFont()`
`pattern`	Pattern	`getPattern()`, `setPattern()`
`colorPattern`	ColorPattern	`getColorPattern()`, `setColorPattern()`
`gradientPattern`	GradientPattern	`getGradientPattern()`, `setGradientPattern()`
`lineStyle`	LineStyle	`getLineStyle()`, `setLineStyle()`
`fillStyle`	FillStyle	`getFillStyle()`, `setFillStyle()`
`fillRule`	FillRule	`getFillRule()`, `setFillRule()`
`arcMode`	ArcMode	`getArcMode()`, `setArcMode()`

Constructor & Destructor Documentation

§ IlvSimpleGraphic()

IlvSimpleGraphic::IlvSimpleGraphic	(	IlvDisplay *	display,
		IlvPalette *	palette = `0`
	)

Initializes a new IlvSimpleGraphic.

The IlvSimpleGraphic constructor needs the IlvPalette object to which it is attached to obtain resources. The palette parameter can be set to a specific value or left unspecified where it takes the value 0. When the palette is set to 0, the default palette of the display object is used. This palette is the one returned by the member function IlvDisplay::defaultPalette() of the IlvDisplay class. The palette parameter is locked when the object is created.

Parameters

display	The display where this object is created.
palette	The palette of the display object.

§ ~IlvSimpleGraphic()

virtual IlvSimpleGraphic::~IlvSimpleGraphic ( )

virtual

Destructor.

The destructor unlocks the palette.

Member Function Documentation

§ applyResources()

virtual void IlvSimpleGraphic::applyResources	(	const char *	storageName,
		const char *	storageClassName,
		const char *	objectName,
		const char *	objectClassName,
		IlvDisplay *	display = `0`
	)

virtual

Applies resources on a graphic object.

Searches for resources that match storageName.objectName.resource, or storageName.objectClassName.resource, or storageClassName.objectName.resource, or storageClassName.objectClassName.resource, in this order, and applies these resources to the object.

The resources taken into account by the class IlvGraphic are only geometric:

x
y
h or height
w or width

The class IlvSimpleGraphic also applies the following graphic resources, if and only if the object has the default display palette:

foreground
background
font
pattern
colorPattern
lineStyle
lineWidth
fillStyle
arcMode
fillRule

Parameters

storageName	The storage name.
storageClassName	The generic name of the storage instance.
objectName	The object name.
objectClassName	The generic name of the object class.
display	The display where this object is created.

§ getLookupStringInputMethod()

virtual int IlvSimpleGraphic::getLookupStringInputMethod	(	IlvEvent &	event,
		char *	bufferReturn,
		int	bytesBuffer,
		int *	statusReturn
	)

virtual

Gets the preedit string from an input method.

This method is offered to developers of subclasses of IlvSimpleGraphic wanted to control input and connection to an input method, so that input can be done in the current locale. It returns the preedit string from an input method.

It should be called from the handleEvent() when getting a key press event (in the IlvKeyDown case).

Parameters

event	The key press event.
bufferReturn	The returned multibyte buffer containing the preedit string. You must pre-allocate this buffer so that it can be filled, and the actual size of the buffer can be enlarged using this same method (see statusReturn).
bytesBuffer	The size in bytes of the allocated buffer.
statusReturn	The return status of the operation. This can be: `0` for success. In that case the returned value represents the number of bytes. `1` for failure in case of an allocated buffer too small. In that case the returned value is the needed size. Others values for failure.

Returns: The number of returned bytes, if successful.

§ getMode()

§ invert()

virtual void IlvSimpleGraphic::invert ( IlBoolean temp = IlFalse )

virtual

Highlights the object.

Highlights the object. It is implemented as swapping the foreground and background colors of the object, but can have other implementations in derived subclasses. The parameter temp controls the way you toggle between the background and the foreground. If temp is omitted or is IlFalse, then a new palette is computed by calling the IlvDisplay::getPalette() method. If temp is IlTrue, the object palette is inverted, and thus all the objects referencing this palette will be affected.

Parameters

temp	If `IlTrue`, highlights the object.

Reimplemented from IlvGraphic.

Reimplemented in IlvGadget, IlvReliefGauge, IlvGauge, IlvReliefLine, IlvOutlinePolygon, and IlvReliefRectangle.

§ registerInputMethod()

virtual void IlvSimpleGraphic::registerInputMethod ( ) const

virtual

Controls the connection of a graphic object to an input method.

This method is offered to developers of subclasses of IlvSimpleGraphic wanted to control input and connection to an input method, so that input can be done in the current locale.

This method is used internally when an object is attached to its holder, as long as IlvSetLocale() has been called, and IlvGraphic::needsInputContext() returns IlTrue.

A developer could use it when its graphic object changes its editable state from non-editable to editable.

See also: IlvSetLocale(), IlvGraphic::needsInputContext().

§ setValuesInputMethod()

virtual void IlvSimpleGraphic::setValuesInputMethod	(	IlUShort	count,
		const IlvImValue *	values
	)		const

virtual

Controls the interaction between a graphic object and an input method.

This method is offered to developers of subclasses of IlvSimpleGraphic wanted to control input and connection to an input method, so that input can be done in the current locale. It gives the input method attributes to update the input context.

This method should be called each time an object modifies its position or its appearance so that the input context can be updated, as long as IlvSetLocale() has been called, and IlvGraphic::needsInputContext() returns IlTrue.

It is automatically called from the following methods:

IlvSimpleGraphic::setPalette() to communicate the foreground and background colors.
IlvSimpleGraphic::setBackground() to communicate the background color.
IlvSimpleGraphic::setForeground() to communicate the foreground color.
IlvGadget::applyTransform() to communicate the rectangle size of the object.

as long as IlvSetLocale() has been called, and IlvGraphic::needsInputContext returns IlTrue.

Parameters

count	The number of values.
values	The attributes and values to be passed to an input method to update an input context. See the `IlvImValue` class for more information.

§ unRegisterInputMethod()

virtual void IlvSimpleGraphic::unRegisterInputMethod ( ) const

virtual

Controls the disconnection of a graphic object from an input method.

This method is offered to developers of subclasses of IlvSimpleGraphic wanted to control input and connection to an input method, so that input can be done in the current locale.

This method is used internally when an object is removed from its holder, as long as IlvSetLocale() has been called, and IlvGraphic::needsInputContext() returns IlTrue.

A developer could use it when its graphic object changes its editable state from editable to non-editable.

See also: IlvSetLocale(), IlvGraphic::needsInputContext().

§ unsetFocusInputMethod()

virtual void IlvSimpleGraphic::unsetFocusInputMethod ( ) const

virtual

Controls the interaction between a graphic object and an input method.

This method is offered to developers of subclasses of IlvSimpleGraphic wanted to control input and connection to an input method, so that input can be done in the current locale. It tells the input method that this object has lost the input focus.

This method should be called when an object looses the keyboard focus (usually in the handleEvent() in the IlvKeyboardFocusOut case), as long as IlvSetLocale() has been called, and IlvGraphic::needsInputContext() returns IlTrue.

See also: IlvSetLocale(), IlvGraphic::needsInputContext().
