Detailed DescriptionThe SbBox2s class is a 2 dimensional box with short integer coordinates​. This box class is used by other classes in Coin for data exchange​. It provides storage for two box corners with short integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates​. See also SbBox2d, SbBox2f, SbBox2i32, SbBox3d, SbBox3f, SbBox3i32, SbBox3s, SbXfBox3d, SbXfBox3f
Constructor & Destructor Documentation
SbBox2s::SbBox2s (void)The default constructor makes an empty box​. References makeEmpty()​.
SbBox2s::SbBox2s (short xmin, short ymin, short xmax, short ymax)Constructs a box with the given corner coordinates​. xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box​. References setBounds()​.
SbBox2s::SbBox2s (const SbVec2s & boxmin, const SbVec2s & boxmax)Constructs a box with the given corners​. The coordinates of min should be less than the coordinates of max if you want to make a valid box​. References setBounds()​.
SbBox2s::SbBox2s (const SbBox2i32 & box) [inline], [explicit]Constructs a box with coordinates from box, converting the coordinates to short integers Since Coin-2​.5
SbBox2s::SbBox2s (const SbBox2f & box) [inline], [explicit]Constructs a box with coordinates from box, converting the coordinates to short integers Since Coin-2​.5
SbBox2s::SbBox2s (const SbBox2d & box) [inline], [explicit]Constructs a box with coordinates from box, converting the coordinates to short integers Since Coin-2​.5
SbBox2s::~SbBox2s (void)Default destructor does nothing​.
Member Function Documentation
