spin_mult¶: Alias for field number 3

struc¶: Alias for field number 1

class schrodinger.application.jaguar.gui.input_tab_widgets_pka.InputEntriesColumnsPka¶

Bases: object

Column constants for the pKa selected entries table

class schrodinger.application.jaguar.gui.input_tab_widgets_pka.InputEntriesModelPka(parent)¶

Bases: schrodinger.application.jaguar.gui.input_tab_widgets.InputEntriesModel

The data model for the pKa selected entries table

Variables:

set_pka_marker (PyQt5.QtCore.pyqtSignal) –

A signal emitted when a new pKa atom should be marked in the workspace. Emitted with two arguments:

The entry id of the structure to be marked (str)

The atom to be marked (schrodinger.structure._StructureAtom)

COLUMN¶: alias of InputEntriesColumnsPka

set_pka_marker¶

ROW_CLASS¶: alias of ProjEntryPka

data(self, QModelIndex, role: int = Qt.DisplayRole) → Any¶

setData(index, value, role=2)¶

Set data for the specified index. The spin multiplicity tool tip will be shown if an invalid spin multiplicity is set, or if a charge is set that renders the spin multiplicity invalid. (The tool tip explains that the default spin multiplicity is being used because the user-specifed value is invalid.)

Parameters:	index (`PyQt5.QtCore.QModelIndex`) – The index to modify value – The value to set role (int) – The role to set data for. Must be Qt.EditRole or setting will fail.
Returns:	True if setting succeeded. False if it failed.
Return type:	bool

getStructures()¶

Get a list of all structures loaded into the table (i.e. all structures selected in the project table) and the associated settings.

Returns:	A list of ProjEntryTuple objects
Return type:	list

checkPkaAtoms()¶

Make sure that all structure have a valid pKa atom selected

Returns:	A tuple of - A list of structures with invalid pKa atoms - A list of structures with no pKa atom
Return type:	tuple

addPkaMarkers(index, start_row, end_row)¶

Add pKa workspace atom markers for the specified rows

Parameters:	index – Not used, but present for Qt compatability start_row (int) – The first row to add a pKa marker to end_row (int) – The last row to add a pKa marker to

removePkaMarkers(index, start_row, end_row)¶

Remove the pKa workspace atom markers for the specified rows

Parameters:	index – Not used, but present for Qt compatibility start_row (int) – The first row to add a pKa marker to end_row (int) – The last row to add a pKa marker to

class schrodinger.application.jaguar.gui.input_tab_widgets_pka.InputEntriesViewPka(parent)¶

Bases: schrodinger.application.jaguar.gui.input_tab_widgets.InputEntriesView

The view for the pKa selected entries table

Variables:

set_pka_marker (PyQt5.QtCore.pyqtSignal) –

A signal emitted when a new pKa atom should be marked in the workspace. Emitted with two arguments:

The entry id of the structure to be marked (str)

List of atoms (schrodinger.structure._StructureAtom) to be marked

COLUMN¶: alias of InputEntriesColumnsPka

set_pka_marker¶

class schrodinger.application.jaguar.gui.input_tab_widgets_pka.AtomSelectionDelegate(parent)¶

Bases: schrodinger.application.jaguar.gui.input_tab_widgets.CommitMultipleDelegate, schrodinger.ui.qt.delegates.DefaultMessageDelegate

A delegate for selecting a pKa atom. The atom name can either be typed into the line edit or selected from the workspace. A tool tip containing instructions will appear when the editor is first open and any time the user hovers their mouse over the editor. If the user clicks on an atom from the wrong structure, the atom will be ignored and a tool tip warning will appear. Clicking on an atom does not close the editor so that the user can immediately pick a different atom if desired.

Variables:

set_pka_marker (PyQt5.QtCore.pyqtSignal) –

A signal emitted when a new pKa atom should be marked in the workspace. Emitted with two arguments:

The entry id of the structure to be marked (str)

List of atoms (schrodinger.structure._StructureAtom) to be marked

MAESTRO_STATUS_MESSAGE = 'Pick an atom to be treated as the pKa atom'¶

TOOL_TIP_INSTRUCTIONS = 'Click an atom in the workspace to\nset it as the pKa atom or type the\natom name here.'¶

TOOL_TIP_WRONG_EID = 'The atom you selected is not\npart of this structure.'¶

set_pka_marker¶

createEditor(self, QWidget, QStyleOptionViewItem, QModelIndex) → QWidget¶

setEditorData(self, QWidget, QModelIndex)¶

setModelData(self, QWidget, QAbstractItemModel, QModelIndex)¶

eventFilter(editor, event)¶

Make sure that the editor doesn’t close when the user clicks on another window since that will prevent the user from being able to click on an atom.

Parameters:	editor (`PyQt5.QtWidgets.QWidget`) – The pKa atom line edit event – A Qt event event – `PyQt5.QtCore.QEvent`
Note:	We don’t need to worry about the case where the user clicks on a different widget in the pKa panel after selecting an atom. Since the editor was the last widget with focus in the pKa panel, it will receive another FocusOut event when the other widget receives focus, and that FocusOut event will cause the editor to close.
