             CoordinateMarkerMixin

Known Subclasses:

A mixin for marking constraints from the Scan or Optimization tabs. Note that this mixin should not be directly applied to a panel. Instead, the OptimizationTabMarkerMixin, ScanTabMarkerMixin, or OptimizationAndScanMixin should be used.

Current limitations:

If the user changes the element of an constrained (or scanned) atom, the constraint (or scan) will not be updated.

Method Details

setup(self)

Initialize self._selected_entries

Overrides: MarkerMixin.setup

_connectMarkerSignals(self, tab)

Connect the signals from the specified tab to the appropriate slots

Parameters:

tab (schrodinger.application.jaguar.gui.tabs.base_tab.BaseTab) - The tab to connect signals for

clearConstraintsIfWorkspace(self, what_changed)

Check to see if coordinate picking is allowed or if constraints need to be cleared in response to a workspace change. This callback is needed when the user adds or deleted atoms.

Parameters:

what_changed (str) - A flag indicating what has changed in the workspace

Decorators:

@af2.maestro_callback.workspace_changed

clearConstraintsIfProject(self)

Check to see if coordinate picking is allowed or if constraints need to be cleared in response to a project table change.

Decorators:

@af2.maestro_callback.project_updated

_clearConstraintsStructureCheck(self)

Only allow coordinate picking if there is exactly one entry in the workspace and it is also selected in the project table. If the selected entry has changed or if the number of atoms in the selected entry has changed, clear all coordinates.

_getSelectedEidsAndLength(self)

Retrieve the entry ids for the structures selected in the project table. If there is exactly one structure selected, also return the number of atoms in that structure.

Returns: tuple

A tuple of:

The entry ids for the structures selected in the project table as a set. If the project table is not available, will be an empty set.
If there is exactly one structure selected in the project table, the number of atoms in that structure. None otherwise.

_setAcceptableConstraintEids(self, eids, picking_err)

Pass the constraint or scan picking restrictions to the appropriate tab.

Parameters:

eids (set) - The entry ids for which coordinate picking is acceptable.
picking_err (str or NoneType) - If picking should not be allowed at all, this is the text of the error that will displayed to the user. If picking is allowed, should be None.

_addCoordMarker(self, atom_nums, coordinate_type)

Add a marker to the specified atoms. The settings from _markerSettings will be used to style the marker.

Parameters:

atom_nums (list or QVariant) - A list of atom numbers
coordinate_type - Ignored. Present for compatability with the tab signal.

_optMarkerSettings(self)

Get the marker settings to use for the Optimization tab

Returns: tuple

A tuple of

The alt_color for the marker
A tuple of colors to use for marking (atoms, pairs, angles, torsions)
A tuple of icons to use for marking (atoms, pairs, angles, torsions)

_scanMarkerSettings(self)

Get the marker settings to use for the Scan tab

Returns: tuple

A tuple of

The alt_color for the marker
A tuple of colors to use for marking (atoms, pairs, angles, torsions)
A tuple of icons to use for marking (atoms, pairs, angles, torsions)

_markerSettings(self)

Get the marker settings to use for newly added markers. This function must be defined in subclasses.

Returns: tuple

A tuple of

The alt_color for the marker
A tuple of colors to use for marking (atoms, pairs, angles, torsions)
A tuple of icons to use for marking (atoms, pairs, angles, torsions)

Note: Marker icon constants aren't defined until runtime because they're not importable outside of Maestro, so these values can't be directly set as class constants, hence this function.

_getMarkerSettings(self, num_atoms)

Get the marker settings to use for a newly added marker with the specified number of atoms. The marker settings from _markerSettings will be used.

Parameters:

num_atoms (int) - The number of atoms that will be marked

Returns: dict

A dictionary containing the appropriate addMarker() arguments for color, alt_color, and icon

_applyMarkerSettings(self, num_atoms, alt_color, colors, icons)

Get the marker settings to use for a newly added marker with the specified number of atoms.

Parameters:

num_atoms (int) - The number of atoms that will be marked
alt_color (tuple, str, int, or schrodinger.structutils.color) - The alt_color for the marker
colors (tuple) - A tuple of colors to use for marking (atoms, pairs, angles, torsions)
icons (tuple) - A tuple of icons to use for marking (atoms, pairs, angles, torsions)

Returns: dict

A dictionary containing the appropriate addMarker() arguments for color, alt_color, and icon

_deleteCoordMarker(self, atom_nums)

Remove the marker from the specified atoms

Parameters:

atom_nums (list or QVariant) - A list of atom numbers

_getAtomsFromInts(self, atom_nums)

Get the workspace atoms with the specified atom numbers

Parameters:

atom_nums (list or QVariant) - A list of atom numbers

Returns: list

A list of atom objects

_addHighlighting(self, atom_nums)

Highlight the marker for the specified atoms

Parameters:

atom_nums (list or QVariant) - A list of atom numbers

_removeHighlighting(self, atom_nums)

Un-highlight the marker for the specified atoms

Parameters:

atom_nums (list or QVariant) - A list of atom numbers

_selected_eid_atom_total

If there is only one entry id in _selected_eids, then _selected_eid_atom_total contains the number of atoms in that entry. If the number of atoms changes, all constraints will be cleared. If _selected_eids is empty of contains more than one entry id, then _selected_eid_atom_total is None.

A set of entry ids currently selected in the project table. If the selected entries changes, all constraints will be cleared.

Type:: set
