IlvMarker
subclass with zoomable capability.
Library: views
This class implements a zoomable behavior on top of the IlvMarker
class:
1
, the symbol size is reduced to fit the transformed bounding box of the initial marker. 1
, the symbol size stays fixed to the one provided by the IlvMarker::setSize
method. The benefit of using this class instead of the IlvMarker
is twofold:
IlvZoomableMarker
can be stored in a quadtree, which allows a significant gain in performance when the number of markers is important.
|
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 IlvMarker.
|
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 IlvMarker.
|
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 IlvMarker.
|
virtual |
Checks whether this object is zoomable.
IlTrue
if the graphic object can be zoomed, and IlFalse
otherwise. IsZoomAllowed()
, AllowZoom()
. Reimplemented from IlvMarker.
