- class schrodinger.ui.qt.select_residues_dialog.ResiduesModel¶
Bases:
PyQt6.QtCore.QAbstractTableModel
This model represents the active site residues table.
- __init__()¶
- rowCount(ignored=None)¶
Returns number of rows
- columnCount(ignored=None)¶
Returns number of columns
- data(index, role)¶
Given a cell index, return the string that should be displayed in that cell. Used by the View class.
- headerData(section, orientation, role)¶
Returns the string that should be displayed in the specified header cell. Used by the View.
- setAllData(rows)¶
- addRow(res)¶
Add the specified residue to the table (unless it’s already there)
- removeRows(self, row: int, count: int, parent: QModelIndex = QModelIndex()) bool ¶
- removeAllRows()¶
- getAllData()¶
Return a list of
picking.ResidueRow
objects for all rows in the table.
- class schrodinger.ui.qt.select_residues_dialog.SelectResiduesDialog(panel, title=None, label_text=None, allow_empty_list=False, markers_color=None, hide_markers_on_close=False)¶
Bases:
schrodinger.ui.picking.PickResiduesChangedMixin
,PyQt6.QtWidgets.QDialog
Class for allowing the user to select one or more residues in the Workspace - for example, active site residues.
- __init__(panel, title=None, label_text=None, allow_empty_list=False, markers_color=None, hide_markers_on_close=False)¶
Create a new dialog instance
- Parameters
panel (
QtWidgets.QWidget
) – The parent panel for this dialog.title – Optional title for the dialog. Default is “Active Site Residues”.
label_text (str) – Optional label text for describing what the residues are to be picked for. Default is “Pick residues to define the active site:”
allow_empty_list (bool) – Whether it is OK to remove all selected residues from the list and close the dialog with an empty res list.
markers_color (3-tuple of floats, 0 <= value <= 1.0, or None) – 3-tuple of floats between 0 and 1 each to define a color to use for marking selected residues. If a value of None is passed, no markers will be added.
hide_markers_on_close (bool) – indicates whether Maestro Workspace markers should be hidden when dialog is closed. In this mode any existing markers will be shown when dialog is shown.
- display()¶
Open the dialog.
- pickResidueAtom(anum)¶
- openSelectDialog()¶
Opens an atom selection dialog. When a user specifies the ASL, all atoms matching the ASL will be extended to full residues, and each of these residues will be added to the residues table.
- addResidueToTable(res)¶
Adds a row to the table for the specified residue.
- Parameters
res (
schrodinger.structure.Structure
) – Residue to be added.
- residuesModelUpdated()¶
Called when rows are added to or removed from the residues table.
- residueSelectionChanged()¶
Called when residue rows are selected or de-selected.
- removeSelectedRows()¶
Called when “Delete” button is clicked.
- accept()¶
If the user input is valid, accept and close the dialog. Otherwise, display a warning message to the user.
- reject()¶
Called when the user closes the dialog with cancel or X.
- showAllMarkers()¶
Displays all workspace markers for each row.
- hideAllMarkers()¶
Hides the markers for all rows.
- clear()¶
Clear the residues table.
- getResiduesList()¶
Return the list of residue strings (e.g. [‘A:217’, ‘A:231b’]) of the selected residues.
:return List of residue strings for each row. @rtyp: list of str
- getResiduesCenter()¶
Return the (x, y, z) tuple for the center of the selected residues. Will raise ValueError if no residues were picked.
- Returns
Tuple of center x, y, z coordinates
- Return type
tuple of (float, float, float)
