Member Function Documentation

getMoleculeLayer() [1/2]

Layer & getMoleculeLayer ( )

static

Returns

active molecule Layer

getMoleculeLayer() [2/2]

Layer & getMoleculeLayer ( const Molecule * mol )

static

Returns

Layer from mol and creates MoleculeInfo if not exists

getMoleculeInfo() [1/2]

std::shared_ptr< MoleculeInfo > getMoleculeInfo ( )

static

Returns

the MoleculeInfo from active molecule

getMoleculeInfo() [2/2]

std::shared_ptr< MoleculeInfo > getMoleculeInfo ( const Molecule * mol )

static

Returns

the MoleculeInfo from mol

layerCount()

size_t layerCount ( )

static

Returns

the layer quantity from activeMolecule

activeMoleculeInfo()

std::shared_ptr< MoleculeInfo > activeMoleculeInfo ( )

staticprotected

Returns

the layer state of the active molecule, or nullptr when there is no active molecule.

findMoleculeInfo()

std::shared_ptr< MoleculeInfo > findMoleculeInfo ( const Molecule * mol )

staticprotected

Returns

the layer state of mol, or nullptr when mol is null.

setActiveMolecule()

void setActiveMolecule ( const Molecule * mol )

staticprotected

Point the layer GUI and the render plugins at mol.

Member Data Documentation

m_activeInfo

std::weak_ptr<MoleculeInfo> m_activeInfo

staticprotected

The layer state of the molecule the GUI is acting on, held weakly.

Deliberately not a const Molecule*. Layer state is owned by each Molecule, so nothing here keeps one alive, and a raw pointer would dangle the moment the active molecule was destroyed – reading it would then either fault or silently report whatever object had taken over that address. A weak_ptr simply stops resolving instead.
