| 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 | ||
| ) |
| 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.
| 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 |

| 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.

| 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.

| 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.
