Detailed Description

A base class for fltk::Widget

---

Constructor & Destructor Documentation

fltk::Rectangle::Rectangle (  int  x, int  y, int  w, int  h )  [inline]

Constructor that sets x(), y(), w(), and h().

fltk::Rectangle::Rectangle (  int  w, int  h )  [inline]

Constructor that sets x() and y() to zero, and sets w() and h().

fltk::Rectangle::Rectangle (  const Rectangle &  r  )  [inline]

Copy constructor.

fltk::Rectangle::Rectangle (  const Rectangle &  r, int  w, int  h, int  flags = 0 )  [inline]

Constructor that calls set().

Member Function Documentation

int fltk::Rectangle::b (   )  const [inline]

Return y()+h(), the bottom edge of the rectangle.

int fltk::Rectangle::baseline_y (   )  const

Where to put baseline to center current font nicely

int fltk::Rectangle::center_x (   )  const [inline]

Integer center position. Rounded to the left if w() is odd.

int fltk::Rectangle::center_y (   )  const [inline]

Integer center position. Rounded to lower y if h() is odd.

bool fltk::Rectangle::contains (  int  x, int  y )  const [inline]

True if rectangle contains the pixel who's upper-left corner is at x,y

bool fltk::Rectangle::empty (   )  const [inline]

True if w() or h() are less or equal to zero.

void fltk::Rectangle::h (  int  v  )  [inline]

Change h() by moving the bottom edge. y() does not change.

int fltk::Rectangle::h (   )  const [inline]

Distance between top and bottom edges

void fltk::Rectangle::inset (  int  d  )  [inline]

Move all edges in by d. See also Symbol::inset()

void fltk::Rectangle::merge (  const Rectangle &  r  )

calculate bounding box of this union r

void fltk::Rectangle::move (  int  dx, int  dy )  [inline]

Move entire rectangle by given distance in x and y.

void fltk::Rectangle::move_b (  int  d  )  [inline]

Add d to b() and h().

void fltk::Rectangle::move_r (  int  d  )  [inline]

Add d to r() and w().

void fltk::Rectangle::move_x (  int  d  )  [inline]

Add d to x() without changing r() (it reduces w() by d).

void fltk::Rectangle::move_y (  int  d  )  [inline]

Add d to y() without changing b() (it reduces h() by d).

bool fltk::Rectangle::not_empty (   )  const [inline]

Same as !empty(), true if w() and h() are both greater than zero.

int fltk::Rectangle::r (   )  const [inline]

Return x()+w(), the right edge of the rectangle.

void fltk::Rectangle::set (  const Rectangle &  r, int  w, int  h, int  flags = 0 )

Sets x, y, w, h so that's it's centered or aligned (if flags!=0) inside the source r

void fltk::Rectangle::set (  int  x, int  y, int  w, int  h )  [inline]

Set x(), y(), w(), and h() all at once.

void fltk::Rectangle::set_b (  int  v  )  [inline]

Change b() without changing y(), by changine the height.

void fltk::Rectangle::set_r (  int  v  )  [inline]

Change r() without changing x(), by changine the width.

void fltk::Rectangle::set_x (  int  v  )  [inline]

Change x() without changing r(), by changing the width.

void fltk::Rectangle::set_y (  int  v  )  [inline]

Change y() without changing b(), by changing the height.

void fltk::Rectangle::w (  int  v  )  [inline]

Change w() by moving the right edge. x() does not change.

int fltk::Rectangle::w (   )  const [inline]

Distance between left and right edges

void fltk::Rectangle::x (  int  v  )  [inline]

Move the rectangle so the left edge is at v.

int fltk::Rectangle::x (   )  const [inline]

Left edge

void fltk::Rectangle::y (  int  v  )  [inline]

Move the rectangle so the top edge is at v.

int fltk::Rectangle::y (   )  const [inline]

Top edge
