gcp::Arrow::Arrow | ( | gcu::TypeId | Type | ) |
Type | an arrow type id. |
Used to create an arrow of type Id. Should only be called from the constructor of a derived class.
virtual gcp::Arrow::~Arrow | ( | ) | [virtual] |
The destructor.
bool gcp::Arrow::GetCoords | ( | double * | xstart, |
double * | ystart, | ||
double * | xend, | ||
double * | yend | ||
) | const |
xstart | where to store the x coordinate of the start point. |
ystart | where to store the y coordinate of the start point. |
xend | where to store the x coordinate of the end point. |
yend | where to store the y coordinate of the end point. |
Retrieves the position of the arrow.
bool gcp::Arrow::GetCoords | ( | double * | x, |
double * | y, | ||
double * | z = NULL |
||
) | const [virtual] |
x | a pointer to the double value which will receive the x coordinate of the Arrow. |
y | a pointer to the double value which will receive the y coordinate of the Arrow. |
z | a pointer to the double value which will receive the z coordinate of the Arrow or NULL for 2D representations. |
Retrieves the coordinates of this Arrow.
Reimplemented from gcu::Object.
double gcp::Arrow::GetYAlign | ( | ) | [virtual] |
Used to retrieve the y coordinate for alignment.
Reimplemented from gcu::Object.
bool gcp::Arrow::Load | ( | xmlNodePtr | node | ) | [virtual] |
node,: | a pointer to the xmlNode containing the serialized arrow. |
Used to load an Arrow in memory. This method must be called from derived classes overloaded Load methods.
Reimplemented from gcu::Object.
Reimplemented in gcp::MesomeryArrow, and gcp::ReactionArrow.
void gcp::Arrow::Move | ( | double | x, |
double | y, | ||
double | z = 0 |
||
) | [virtual] |
x,: | the x component of the transation vector. |
y,: | the y component of the transation vector. |
z,: | the z component of the transation vector (unused). |
Used to move an arrow. The third parameter is not taken into account.
Reimplemented from gcu::Object.
Reimplemented in gcp::ReactionArrow.
std::string gcp::Arrow::Name | ( | ) | [protected, virtual] |
Reimplemented from gcu::Object.
Reimplemented in gcp::MesomeryArrow, and gcp::ReactionArrow.
bool gcp::Arrow::Save | ( | xmlDocPtr | xml, |
xmlNodePtr | node | ||
) | const [protected] |
xml,: | the xmlDoc used to save the document. |
node,: | the node representing the Object. |
This method must be called from derived classes overloaded Save methods.
void gcp::Arrow::SetCoords | ( | double | xstart, |
double | ystart, | ||
double | xend, | ||
double | yend | ||
) |
xstart | the x coordinate of the start point. |
ystart | the y coordinate of the start point. |
xend | the x coordinate of the end point. |
yend | the y coordinate of the end point. |
Sets the position and length of an arrow.
bool gcp::Arrow::SetProperty | ( | unsigned | property, |
char const * | value | ||
) | [virtual] |
property | the property id as defined in objprops.h |
value | the property value as a string |
Used when loading to set common properties to arrows. Only one property is currently supported: gcu::GCU_PROP_ARROW_COORDS.
Reimplemented from gcu::Object.
Reimplemented in gcp::ReactionArrow.
void gcp::Arrow::SetSelected | ( | int | state | ) | [virtual] |
state,: | the selection state of the arrow. |
Used to set the selection state of the arrow. The values of state might be gcp::SelStateUnselected, gcp::SelStateSelected, gcp::SelStateUpdating, or gcp::SelStateErasing.
Reimplemented from gccv::ItemClient.
Reimplemented in gcp::ReactionArrow.
