Graphic class.
Library: views
An IlvLine object appears as a straight line between two given points.
IlvMakeLineInteractor.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 IlvSimpleGraphic and adds the following ones:
| Name | Type | Equivalent methods |
|---|---|---|
from | IlvPoint | getFrom(), setFrom() |
to | IlvPoint | getTo(), setTo() |
| IlvLine::IlvLine | ( | IlvDisplay * | display, |
| const IlvPoint & | from, | ||
| const IlvPoint & | to, | ||
| IlvPalette * | palette = 0 |
||
| ) |
Constructor.
The constructor initializes a new instance of the IlvLine class by drawing a line from two provided points.
boundingBox() member function of IlvLine does not take into account the line-width parameter set in the palette object it uses.| display | A pointer to the display object that will display this line. |
| from | The source point of this line. |
| to | The destination point of this line. |
| palette | A pointer to the palette that will be used by this object. If left unspecified or set to 0, the default palette of the display (see IlvDisplay::defaultPalette()) will be used. |
|
virtual |
Applies a transformation function to the graphic object.
Applies the transformer t to the shape of the object. Unless the transformation is a scaling operation, the result of applying it to certain objects can be insignificant. For example, applying a non-scaling transformer to an IlvRectangle object is meaningless, since the rectangle remains a rectangle. On the other hand, meaningful transformations can be applied to objects that are instances of types such as IlvLine or IlvPolyPoints.
applyTransform() is one of the most important method to be rewritten for classes derived from IlvGraphic, since it is called by the resize(), move(), moveResize(), scale(), etc., methods.| t | The transformer value. If 0, no transformation is performed. |
Implements IlvGraphic.
|
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. |
Implements IlvGraphic.
Reimplemented in IlvArrowLine, and IlvReliefLine.
|
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 IlvGraphic.
Reimplemented in IlvReliefLine.
|
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. |
Implements IlvGraphic.
Reimplemented in IlvArrowLine, and IlvReliefLine.
| const IlvPoint& IlvLine::getFrom | ( | ) | const |
Gets the line starting point.
| const IlvPoint& IlvLine::getTo | ( | ) | const |
Gets the line ending point.
| void IlvLine::setFrom | ( | const IlvPoint & | p | ) |
Sets the line starting point.
| p | The new starting point of this line. |
| void IlvLine::setTo | ( | const IlvPoint & | to | ) |
Sets the line ending point.
| to | The new ending point of this line. |
|
virtual |
Flips a graphic object.
Flips the object about one of the horizontal or vertical axis (or a combination of the two). The axis is given by the axis parameter, which you can give the value IlvHorizontal, in which case the flip takes place around the horizontal axis of the object, or IlvVertical, which flips the object around the vertical axis. You can also use the IlvCenter value to flip the object around its center.
The default implementation calls the member function applyTransform() with a transformer corresponding to the required symmetry.
| axis | The axis around which flipping occurs. |
Reimplemented from IlvGraphic.
