The minimum value of TQCOORD is TQCOORD_MIN (-2147483648) and - the maximum value is TQCOORD_MAX (2147483647). - - 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. - - Generally, \e{width = right - left + 1} and \e{height = bottom - - top + 1}. 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. - - 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. - - A TQRect can be constructed with a set of left, top, width and - height integers, from two TQPoints or from a TQPoint and a TQSize. - After creation the dimensions can be changed, e.g. with setLeft(), - setRight(), setTop() and setBottom(), or by setting sizes, e.g. - setWidth(), setHeight() and setSize(). The dimensions can also be - changed with the move functions, e.g. moveBy(), moveCenter(), - moveBottomRight(), etc. You can also add coordinates to a - rectangle with addCoords(). - - You can test to see if a TQRect contains a specific point with - contains(). You can also test to see if two TQRects intersect with - intersects() (see also intersect()). To get the bounding rectangle - of two TQRects use unite(). - - \sa TQPoint, TQSize -*/ - - -/***************************************************************************** - TQRect member functions - *****************************************************************************/ - -/*! - \fn TQRect::TQRect() - - Constructs an invalid rectangle. -*/ - -/*! - Constructs a rectangle with \a topLeft as the top-left corner and - \a bottomRight as the bottom-right corner. -*/ - -TQRect::TQRect( const TQPoint &topLeft, const TQPoint &bottomRight ) -{ - x1 = (TQCOORD)topLeft.x(); - y1 = (TQCOORD)topLeft.y(); - x2 = (TQCOORD)bottomRight.x(); - y2 = (TQCOORD)bottomRight.y(); -} - -/*! - Constructs a rectangle with \a topLeft as the top-left corner and - \a size as the rectangle size. -*/ - -TQRect::TQRect( const TQPoint &topLeft, const TQSize &size ) -{ - x1 = (TQCOORD)topLeft.x(); - y1 = (TQCOORD)topLeft.y(); - x2 = (TQCOORD)(x1+size.width()-1); - y2 = (TQCOORD)(y1+size.height()-1); -} - -/*! - \fn TQRect::TQRect( int left, int top, int width, int height ) - - Constructs a rectangle with the \a top, \a left corner and \a - width and \a height. - - Example (creates three identical rectangles): - \code - TQRect r1( TQPoint(100,200), TQPoint(110,215) ); - TQRect r2( TQPoint(100,200), TQSize(11,16) ); - TQRect r3( 100, 200, 11, 16 ); - \endcode -*/ - - -/*! - \fn bool TQRect::isNull() const - - Returns TRUE if the rectangle is a null rectangle; otherwise - returns FALSE. - - A null rectangle has both the width and the height set to 0, that - is right() == left() - 1 and bottom() == top() - 1. - - Note that if right() == left() and bottom() == top(), then the - rectangle has width 1 and height 1. - - A null rectangle is also empty. - - A null rectangle is not valid. - - \sa isEmpty(), isValid() -*/ - -/*! - \fn bool TQRect::isEmpty() const - - Returns TRUE if the rectangle is empty; otherwise returns FALSE. - - An empty rectangle has a left() \> right() or top() \> bottom(). - - An empty rectangle is not valid. \c{isEmpty() == !isValid()} - - \sa isNull(), isValid(), normalize() -*/ - -/*! - \fn bool TQRect::isValid() const - - Returns TRUE if the rectangle is valid; otherwise returns FALSE. - - A valid rectangle has a left() \<= right() and top() \<= bottom(). - - Note that non-trivial operations like intersections are not defined - for invalid rectangles. - - \c{isValid() == !isEmpty()} - - \sa isNull(), isEmpty(), normalize() -*/ - - -/*! - Returns a normalized rectangle, i.e. a rectangle that has a - non-negative width and height. - - It swaps left and right if left() \> right(), and swaps top and - bottom if top() \> bottom(). - - \sa isValid() -*/ - -TQRect TQRect::normalize() const -{ - TQRect r; - if ( x2 < x1 ) { // swap bad x values - r.x1 = x2; - r.x2 = x1; - } else { - r.x1 = x1; - r.x2 = x2; - } - if ( y2 < y1 ) { // swap bad y values - r.y1 = y2; - r.y2 = y1; - } else { - r.y1 = y1; - r.y2 = y2; - } - return r; -} - - -/*! - \fn int TQRect::left() const - - Returns the left coordinate of the rectangle.
