Port class.
Library: xviews or winviews or mviews (mutually exclusive)
The IlvSystemPort
class defines the area in which you can draw. This area can be a real place or a virtual place. In the first case, the user draws directly into a region of the screen of the workstation. In the second case, the user draws into a bitmap in memory. Classes are derived from IlvSystemPort
to accommodate these two possibilities.
- IlvSystemPort object: A rectangular area -
IlvAbstractView
, IlvBitmap
. 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 IlvPort
.

Draws a string at the given position.
Draws a string at the position referred to as position. The text to be drawn is given in the string parameter and its length is set in the length integer parameter. For this length parameter you can provide a negative number -1
instead of giving the real length. Text length is then computed internally since string is handled as a zero-terminated character array. The align parameter indicates how the string is to be aligned with respect to the position point. For this alignment, the y-coordinate of the position point represents the baseline, and the options are IlvLeft
, IlvRight
, and IlvCenter
.

mode or in IlvArcChord
mode.
palette | The palette to use for the fill color of the arc. |
rect | The bounding box of the ellipse for the arc. |
start | The start angle in degrees. |

virtual |
Fills the shape defined by the given paths.
Fills the shape defined by all the paths described in the IlvPointArray
array pathArray, with the IlvPalette
palette. If count is 1, fillPaths
may be seen as the drawing of a polygon. If none of the paths provided intersect, each polygon is drawn with the palette. The drawing becomes more complex when the paths intersect. A simple way to see this drawing is that when filled areas overlap, the intersection is empty. When a third area intersects with the first two areas, the intersection is filled.
The two objects have no filled intersection.
The small gray area in the middle represents the filled intersection of these three objects, while the white spaces are the overlapping areas between two objects. (For the purpose of this diagram, rectangles have been outlined).
palette | The palette to use for the fill color of the paths. |
count | The number of paths provided in the IlvPointArray array. |
pathArray | The array of paths. |

palette | The palette to use for the fill color of the polygon. |
count | The number of points. |
points | The points in the polyline. |
