Represents mesomery relationships.
Definition at line 41 of file mesomery.h.
gcp::Mesomery::Mesomery | ( | ) |
The default constructor. Builds a new empty mesomery relationship.
void gcp::Mesomery::Align | ( | ) |
Aligns the children.
bool gcp::Mesomery::Build | ( | std::set< Object * > const & | Children | ) | throw (std::invalid_argument) |
Children | the molecules and arrow involved in the mesomery. |
Tries to associate mesomers and arrows so that the relationship is clearly established and aligns the objects. On failure, it throws an std::invalid_argument exception.
bool gcp::Mesomery::BuildContextualMenu | ( | gcu::UIManager * | UIManager, |
gcu::Object * | object, | ||
double | x, | ||
double | y | ||
) | [virtual] |
UIManager | the gcu::UIManager to populate. |
object | the Object on which occured the mouse click. |
x | x coordinate of the mouse click. |
y | y coordinate of the mouse click. |
Builds the contextual menu for the mesomery.
Reimplemented from gcu::Object.
double gcp::Mesomery::GetYAlign | ( | ) | [virtual] |
Reimplemented from gcu::Object.
bool gcp::Mesomery::Load | ( | xmlNodePtr | node | ) | [virtual] |
node,: | a pointer to the xmlNode containing the serialized arrow. |
Used to load an arrow in memory.
Reimplemented from gcu::Object.
std::string gcp::Mesomery::Name | ( | ) | [virtual] |
Reimplemented from gcu::Object.
bool gcp::Mesomery::OnSignal | ( | gcu::SignalId | Signal, |
gcu::Object * | Child | ||
) | [virtual] |
Signal | the appropriate SignalId |
Child | the child which emitted the signal or NULL |
This function is called by the framework one of the molecules or arrows has changed. Realigns if the mesomery is still valid or destroys it.
Reimplemented from gcu::Object.
void gcp::Mesomery::Transform2D | ( | gcu::Matrix2D & | m, |
double | x, | ||
double | y | ||
) | [virtual] |
m | the Matrix2D of the transformation. |
x | the x component of the center of the transformation. |
y | the y component of the center of the transformation. |
Mesomeries can't be currently rotated. This method don't do anything. It is just there to inhibit the default behavior.
Reimplemented from gcu::Object.
bool gcp::Mesomery::Validate | ( | bool | split | ) |
split | whether to split the mesomery when arrows are missing. |
Checks the validity of the mesomery, at least that each arrow is associated with two mesomers and all mesomers are related by arrows. Currently it does not check that the molecules are really mesomeric, but this might be implemented in the future.
