The TQRect class defines a rectangle in the plane.
< p >
< p > A rectangle is internally represented as an upper-left corner and
a bottom-right corner, but it is normally expressed as an
upper-left corner and a size.
< p > The coordinate type is TQCOORD (defined in < a href = "tqwindowdefs-h.html" > tqwindowdefs.h< / a > as < tt > int< / tt > ). The minimum value of TQCOORD is TQCOORD_MIN (-2147483648) and
the maximum value is TQCOORD_MAX (2147483647).
< p > Note that the size (width and height) of a rectangle might be
different from what you are used to. If the top-left corner and
the bottom-right corner are the same, the height and the width of
the rectangle will both be 1.
< p > Generally, < em > width = right - left + 1< / em > and < em > height = bottom - top + 1< / em > . We designed it this way to make it correspond to
rectangular spaces used by drawing functions in which the width
and height denote a number of pixels. For example, drawing a
rectangle with width and height 1 draws a single pixel.
< p > The default coordinate system has origin (0, 0) in the top-left
corner. The positive direction of the y axis is down, and the
positive x axis is from left to right.
< p > A TQRect can be constructed with a set of left, top, width and
height integers, from two TQPoints or from a < a href = "tqpoint.html" > TQPoint< / a > and a < a href = "tqsize.html" > TQSize< / a > .
After creation the dimensions can be changed, e.g. with < a href = "#setLeft" > setLeft< / a > (),
< a href = "#setRight" > setRight< / a > (), < a href = "#setTop" > setTop< / a > () and < a href = "#setBottom" > setBottom< / a > (), or by setting sizes, e.g.
< a href = "#setWidth" > setWidth< / a > (), < a href = "#setHeight" > setHeight< / a > () and < a href = "#setSize" > setSize< / a > (). The dimensions can also be
changed with the move functions, e.g. < a href = "#moveBy" > moveBy< / a > (), < a href = "#moveCenter" > moveCenter< / a > (),
< a href = "#moveBottomRight" > moveBottomRight< / a > (), etc. You can also add coordinates to a
rectangle with < a href = "#addCoords" > addCoords< / a > ().
< p > You can test to see if a TQRect contains a specific point with
< a href = "#contains" > contains< / a > (). You can also test to see if two TQRects intersect with
< a href = "#intersects" > intersects< / a > () (see also < a href = "#intersect" > intersect< / a > ()). To get the bounding rectangle
of two TQRects use < a href = "#unite" > unite< / a > ().
