The TQCanvasLine class provides a line on a < a href = "tqcanvas.html" > TQCanvas< / a > .
< p >
< p > The line inherits functionality from < a href = "tqcanvaspolygonalitem.html" > TQCanvasPolygonalItem< / a > , for
example the < a href = "tqcanvaspolygonalitem.html#setPen" > setPen< / a > () function. The start and end points of the
line are set with < a href = "#setPoints" > setPoints< / a > ().
< p > Like any other canvas item lines can be moved with
< a href = "tqcanvasitem.html#move" > TQCanvasItem::move< / a > () and < a href = "tqcanvasitem.html#moveBy" > TQCanvasItem::moveBy< / a > (), or by setting
coordinates with < a href = "tqcanvasitem.html#setX" > TQCanvasItem::setX< / a > (), < a href = "tqcanvasitem.html#setY" > TQCanvasItem::setY< / a > () and
< a href = "tqcanvasitem.html#setZ" > TQCanvasItem::setZ< / a > ().
< p > See also < a href = "graphics.html" > Graphics Classes< / a > and < a href = "images.html" > Image Processing Classes< / a > .

< h3 class = fn > < a name = "TQCanvasLine" > < / a > TQCanvasLine::TQCanvasLine ( < a href = "tqcanvas.html" > TQCanvas< / a > * canvas )
< / h3 >
Constructs a line from (0,0) to (0,0) on < em > canvas< / em > .
< p > < p > See also < a href = "#setPoints" > setPoints< / a > ().
< h3 class = fn > < a name = "~TQCanvasLine" > < / a > TQCanvasLine::~TQCanvasLine ()
< / h3 >
Destroys the line.
< h3 class = fn > < a href = "tqpoint.html" > TQPoint< / a > < a name = "endPoint" > < / a > TQCanvasLine::endPoint () const
< / h3 >
< p > Returns the end point of the line.
< p > < p > See also < a href = "#setPoints" > setPoints< / a > () and < a href = "#startPoint" > startPoint< / a > ().
< h3 class = fn > int < a name = "rtti" > < / a > TQCanvasLine::rtti () const< tt > [virtual]< / tt >
< / h3 >
Returns 7 (TQCanvasItem::Rtti_Line).
< p > < p > See also < a href = "tqcanvasitem.html#rtti" > TQCanvasItem::rtti< / a > ().
< p > Reimplemented from < a href = "tqcanvaspolygonalitem.html#rtti" > TQCanvasPolygonalItem< / a > .
< h3 class = fn > void < a name = "setPoints" > < / a > TQCanvasLine::setPoints ( int xa, int ya, int xb, int yb )
< / h3 >
Sets the line's start point to (< em > xa< / em > , < em > ya< / em > ) and its end point to
(< em > xb< / em > , < em > yb< / em > ).
< p > Example: < a href = "canvas-example.html#x2922" > canvas/canvas.cpp< / a > .
< h3 class = fn > < a href = "tqpoint.html" > TQPoint< / a > < a name = "startPoint" > < / a > TQCanvasLine::startPoint () const
< / h3 >
< p > Returns the start point of the line.
< p > < p > See also < a href = "#setPoints" > setPoints< / a > () and < a href = "#endPoint" > endPoint< / a > ().
