class schrodinger.application.matsci.siteselector.siteselector.CoordinationSite(value)¶

Bases: PyQt6.QtWidgets.QGraphicsTextItem

QGraphicsTextItem for displaying the number of the coordination site

selected¶: Signal when the site is selected

deselected¶: Signal when the site is deselected (a selected site is clicked again

__init__(value)¶

Create a CoordinationSite object

Parameters: value (int) – The number the user will see for this site. Note that this will be one greater than the index into python arrays for this site.

setClickable(state)¶

Set whether this site is clickable

Parameters: state (bool) – Whether the site can be clicked on or not

mousePressEvent(event)¶

Catch when the mouse clicks on this site and select/deselect the site

Parameters: event (QMouseEvent) – The event that generated this call

moveToPosition(xval, yval)¶

Move the label to its starting position - should only be called at the beginning.

setShiftLeft()¶: Set this label as one that shifts to the left when a ligand designator is added to the label.

select(state=True, released=False)¶

Select or deselect the label and emit the proper signal

Parameters: state (bool) – True if the label is to be selected, False if not

addDesignator(text)¶

Add a ligand designator to the label to indicate that it is currently assigned to that ligand coordination site.

Parameters: text (str) – The designator to add to the site label

released(index)¶: A ligand has released this coordination site because a different site was picked.

class schrodinger.application.matsci.siteselector.siteselector.OctahedralSiteSelector¶

A RadioButton that coordinates the information for a ligand coordination site

released¶

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

__init__(ligand_index, *args, **kwargs)¶

Create a SiteRadioButton object

Parameters: ligand_index (int) – The index of the ligand this radio button is for. This should correspond to the order of the ligands top to bottom in the frame.

Other arguments & keywords are passed on to the parent class

sitePicked(site_index)¶

A coordination site was picked while this was the active radiobutton

Parameters: site_index (int) – The index of the site that was picked.

updateLabel()¶: Give the user some indication of what coordination site is currently picked for this button

siteUnpicked(site)¶

A coordination site was just deselected by the user. If this button held that site, it not longer does.

We do not emit the released signal here because the site has already been deselected.

Parameters: site (int) – The index of the site that was unpicked

class schrodinger.application.matsci.siteselector.siteselector.Ligand(row, index, layout=None)¶

Bases: PyQt6.QtWidgets.QFrame

Parameters

row (LigandRow) – The main panel LigandRow object that provides the data for this ligand
index (int) – The ligand index for this ligand (top ligand is 0, next ligand is 1, etc.)
layout (QLayout) – The layout to place this widget row in

getSlots()¶

Return which coordination sites this ligand is connected to

Return type: list
Returns: List of int, each integer is a coordination site index. The first item is for R1, the second, if it exists is for R2. A list item of None is returned if a coordination site has not been set for an R value

class schrodinger.application.matsci.siteselector.siteselector.LigandSelector(ligand_rows, layout=None)¶

Bases: PyQt6.QtWidgets.QFrame

Returns: The currently-checked radio button and its ID (in the button group)

nextButton(id=None)¶

Check the next button in line after the currently checked button

Parameters: id (int) – Button group ID of the button to use as the currently checked button

getSlots()¶

Return the coordination sites picked for all the ligands. The sites will be returned in the same order the ligands appear in the LigandRow objects in the master.

The dialog window that allows the user to select coordination sites for each ligand

SELECTORS = {'Linear': <class 'schrodinger.application.matsci.siteselector.siteselector.LinearSiteSelector'>, 'Octahedral': <class 'schrodinger.application.matsci.siteselector.siteselector.OctahedralSiteSelector'>, 'Square planar': <class 'schrodinger.application.matsci.siteselector.siteselector.SquarePlanarSiteSelector'>, 'Tetrahedral': <class 'schrodinger.application.matsci.siteselector.siteselector.TetrahedralSiteSelector'>, 'Trigonal bipyramidal': <class 'schrodinger.application.matsci.siteselector.siteselector.TrigonalBipyramidalSiteSelector'>, 'Trigonal planar': <class 'schrodinger.application.matsci.siteselector.siteselector.TrigonalPlanarSiteSelector'>}¶

Parameters

geometry (str) – The VESPR geometry of the complex
row – list of LigandRow objects to extract ligands from
parent (QWidget) – The window to display this dialog over
defined_slots (list) – Each item in the list is the slot that coordinate site will use. The first item of the list is the slot for the R1 site of the first ligand in the first ligand row. The second item is the slot for the R2 site of the first ligand in the first ligand row (if that ligand is bidentate) or the R1 site of the next ligand, etc. A slot, in this case, is the metal atom coordination site.

siteDeselected(site)¶

A coordination site was deselected by clicking on it. Let the radio buttons know so the one that was holding it will know it is no longer holding it.

Parameters: site (int) – The coordination site that was deselected. This value will be one less than what the user sees. (Site 1 emits site=0)

siteSelected(site)¶

A coordination site was selected. Let the current radiobutton know that it has a site, update the site label, and move to the next ligand site.

Parameters: site (int) – The coordination site that was selected. This value will be one less than what the user sees. (Site 1 emits site=0)

accept()¶: Save button callback. Store the selected ligand sites
