Graphic class.
Library: views
The IlvFixedSizeGraphic
class is derived from the basic handle class IlvGraphicHandle
. Thus, an IlvFixedSizeGraphic
object is a kind of handle, which is associated with a certain referenced object of the IlvGraphic
class. An IlvFixedSizeGraphic
instance is drawn by applying to its referenced object a graphic transformation so that the referenced object can never change its visible size. The appropriate transformation is internally computed to achieve this result.
IlvFixedSizeGraphic::IlvFixedSizeGraphic | ( | IlvGraphic * | obj, |
IlBoolean | owner = IlFalse , |
||
IlvPosition | position = IlvBadPosition , |
||
const IlvPoint * | point = 0 |
||
) |
Constructor.
The constructor initializes an instance of IlvFixedSizeGraphic
. The position argument indicates the point in the referenced object (for example, its center or the top-left corner of its bounding box) that must remain at the same position when the object is redrawn. This parameter defaults to a value that leaves the center of the drawn shape at the same location, regardless of any transformer that might be applied when redrawing the graphic object or when locating events that are redirected to these objects. The last parameter, point, can be used to specify the position of a fixed point when this object is transformed (then position is not taken into account). In the case of a transformation that is applied to the object, the transformation is actually applied to this point, and the object is then translated so that the distance between the object and this transformed point is kept constant.
obj | The graphic object to be fixed. |
owner | A Boolean value indicating if it is the owner. |
position | The position of the point to remain fixed. |
point | A fixed point in transformation. |
|
virtual |
Applies a transformation.
t | The transformer that is applied to the referenced graphic object by calling its IlvGraphic::applyTransform() member function. |
Reimplemented from IlvGraphicHandle.
|
virtual |
Retrieves the bounding box of the graphic object.
Sets bbox, the rectangle reference parameter, to be the bounding box of the object. Since the object can appear within a transformed environment (for example, in a multiview editor), an IlvTransformer
object occurs as an optional parameter in order to compute the bounding box in the coordinate system of the transformed environment.
bbox | The bounding box to be set. |
t | A transformer value or 0 if there is no transformation. |
Reimplemented from IlvGraphicHandle.
|
virtual |
Computes the region needed for the drawing of the focus.
This method is called to compute the region needed for the drawing of the focus (see the method drawFocus()
).
r | The region that is updated. |
t | The transformer value. If 0 , no transformation is performed. |
Reimplemented from IlvGraphicHandle.
|
virtual |
Checks whether a point is in the object.
Checks whether the coordinates are located in the shape of this object. A transformation parameter allows you to use the view's coordinate system for this test.
p | The point to be tested. |
tp | The transformed point obtained by applying the transformer t to the point p. |
t | A transformer value, or 0 if there is no transformation. |
IlTrue
when the point p lies inside the outline of the object. Reimplemented from IlvGraphicHandle.
|
virtual |
Draws the graphic object.
Draws the object in the given IlvPort
using the transformer t.
dst | The destination port this object is drawn onto. |
t | The transformer value. If 0 , no transformation is performed. |
clip | The clipping region, relative to the transformed object, or 0 if none. |
Reimplemented from IlvGraphicHandle.
|
virtual |
Draws additional drawings for an object that has the keyboard focus.
This method is called to draw additional drawings when the graphic object has the keyboard focus. The default implementation draws a rectangle around the object. The drawing will be done inside the region returned by computeFocusRegion()
.
dst | The destination port. |
palette | The palette of the object. |
t | The transformer value. If 0 , no transformation is performed. |
clip | The clipping region. |
Reimplemented from IlvGraphicHandle.
const IlvPoint& IlvFixedSizeGraphic::getPoint | ( | ) | const |
Gets the fixed point.
IlvPosition IlvFixedSizeGraphic::getPosition | ( | ) | const |
Gets a fixed point position.
|
virtual |
Determines whether an object with transformation applied is inside the bounding box.
Determines whether an object with transformation applied is inside the bounding box.
r | The region to be tested. |
t | A transformer value, or 0 if there is no transformation. |
IlTrue
when the object, drawn with the transformer t, covers completely the region r. This member function returns IlFalse
when this is not the case. That means that it returns IlTrue
if all rectangles that define the region completely lie inside the object. Reimplemented from IlvGraphicHandle.
|
virtual |
Checks whether a region intersects the bounding box with transformation applied.
Checks whether a region intersects the bounding box with transformation applied.
r | The region to be tested. |
t | A transformer value, or 0 if there is no transformation. |
IlTrue
when the region r overlaps the transformed object (if t is not 0
) and IlFalse
when this is not the case. Reimplemented from IlvGraphicHandle.
void IlvFixedSizeGraphic::setPoint | ( | const IlvPoint & | p | ) |
Sets the fixed point.
p | The new reference point. |
void IlvFixedSizeGraphic::setPosition | ( | IlvPosition | position | ) |
Sets the fixed point position.
Changes the fixed point position by locating the fixed point at the indicated direction relative to the object's bounding box.
position | The new relative position. |
|
virtual |
Queries the zoomable capability.
IlFalse
. An IlvFixedSizeGraphic
is never zoomable. Reimplemented from IlvGraphicHandle.
