Description

IlvGraphic is an abstract base class that:

applies geometric transformations to objects,
changes graphic properties, such as colors, fonts, and patterns gathered in an IlvPalette instance associated with the graphic object.

Rogue Wave Views Views graphic objects inherit attributes from this class.
The shapes of graphic objects are defined by the user and made concrete by various drawing member functions. Other member functions provide information about the graphic objects, and carry out geometric tests concerning the shapes being used. For example, you can check whether a point with given coordinates lies inside a certain shape.
A fundamental inherited class is IlvSimpleGraphic. It implements all the features of the IlvGraphic class. It also implements real geometric-management member functions.
IlvGraphic has groups of member functions that deal with the following items:

Geometric Properties
Graphic Properties
Named Properties
Resource Management
Gadget Properties
Focus Chain Management
Tag Management
User Properties
Class Information
Class Attributes
Input/Output Operations

Type Name Description Notes

IlvRect boundingBox() Returns the bounding box of the object.

IlvGadgetContainer container Returns the container where the graphic object is stored, or NULL if this object is not stored in any container. Note: you are not allowed to store an object in more than a single graphic holder (manager or container).

Boolean contains(IlvPoint point) Returns true when point lies inside the outline of the object.

UInt height Lets you get and set the graphic object's height.

Boolean inside(IlvRect rect) Returns true when the rectangle rect lies completely inside the bounding box of the object and false when this is not the case.

Boolean intersects(IlvRect rect) Returns true when the rectangle rect overlaps the bounding box of the object, and false when the rectangle rect does not overlap the bounding box.

IlvManager manager Returns the manager where the graphic object is stored, or NULL if this object is not stored in any manager. Note: you are not allowed to store an object in more than a single graphic holder (manager or container).

Void move(IlvPoint position) Moves the upper left corner of the bounding box of the object to the position position.

Void reshape(IlvRect position) Sets the bounding box of the object to the rectangle parameter values.

Boolean sensitive Sets the sensitivity of the graphic object.
Returns true if the object is sensitive (that is, if the object responds to user events). Otherwise, it returns false.

Void setCallback(String type, String callback, String language) Sets the callback function name of the graphic object to the value of the callback parameter. The type parameter specifies the type of the callback. The parameter language specifies in which scripting language the callback is defined.
setCallback removes all the callbacks of a given type that were set before the new callback is added.

Void translate(Int dx, Int dy) Translates the position of the object by the vector (dx, dy).

Boolean visible Sets or gets the visibility of the graphic object. This property applies only to an object that is already in the container.

UInt width Lets you get and set the graphic object's width.

Int x Int x

Int y Set and get the graphic object's location.

Type	Name	Description
`IlvRect`	`boundingBox()`	Returns the bounding box of the object.
`IlvGadgetContainer`	`container`	Returns the container where the graphic object is stored, or `NULL` if this object is not stored in any container. Note: you are not allowed to store an object in more than a single graphic holder (manager or container).
`Boolean`	`contains(IlvPoint point)`	Returns `true` when `point` lies inside the outline of the object.
`UInt`	`height`	Lets you get and set the graphic object's height.
`Boolean`	`inside(IlvRect rect)`	Returns `true` when the rectangle `rect` lies completely inside the bounding box of the object and `false` when this is not the case.
`Boolean`	`intersects(IlvRect rect)`	Returns `true` when the rectangle `rect` overlaps the bounding box of the object, and `false` when the rectangle `rect` does not overlap the bounding box.
`IlvManager`	`manager`	Returns the manager where the graphic object is stored, or `NULL` if this object is not stored in any manager. Note: you are not allowed to store an object in more than a single graphic holder (manager or container).
`Void`	`move(IlvPoint position)`	Moves the upper left corner of the bounding box of the object to the position `position.`
`Void`	`reshape(IlvRect position)`	Sets the bounding box of the object to the rectangle parameter values.
`Boolean`	`sensitive`	Sets the sensitivity of the graphic object. Returns `true` if the object is sensitive (that is, if the object responds to user events). Otherwise, it returns `false`.
`Void`	`setCallback(String type, String callback, String language)`	Sets the callback function name of the graphic object to the value of the `callback` parameter. The `type` parameter specifies the type of the callback. The parameter `language` specifies in which scripting language the callback is defined. `setCallback` removes all the callbacks of a given type that were set before the new callback is added.
`Void`	`translate(Int dx, Int dy)`	Translates the position of the object by the vector (`dx`, `dy`).
`Boolean`	`visible`	Sets or gets the visibility of the graphic object. This property applies only to an object that is already in the container.
`UInt`	`width`	Lets you get and set the graphic object's width.
`Int`	`x`	Int x
`Int`	`y`	Set and get the graphic object's location.
