schrodinger.application.msv.gui.row_delegates module

Delegates used to paint an entire row at a time in the MSV tree view. Normal Qt delegates inherit from QStyledItemDelegate and paint a single cell at a time. By painting a row at a time instead, we massively speed up (~6x) painting for the alignment.

schrodinger.application.msv.gui.row_delegates.all_delegates()

Return a list of all delegates in this module. :rtype: list(AbstractDelegate)

class schrodinger.application.msv.gui.row_delegates.AbstractDelegate

Bases: object

Base delegate class. Non-abstract subclasses must must provide appropriate values for ANNOTATION_TYPE and PER_CELL_PAINT_ROLES and must reimplement paintRow.

Variables

• ANNOTATION_TYPE (enum.Enum or None) – The annotation type associated with this class

• PER_CELL_PAINT_ROLES (frozenset) – Data roles that should be fetched per-cell (as opposed to per-row). Note that data for roles in PER_ROW_PAINT_ROLES will be fetched per-row.

• ROW_HEIGHT_CONSTANT (int or None) – The row height, in pixels. Subclasses for rows that should not vary in size as the font size changes should define this value.

• ROW_HEIGHT_SCALE (int) – The row height relative to the font height. This value will be ignored if ROW_HEIGHT_CONSTANT is defined.

ANNOTATION_TYPE = ()

PER_CELL_PAINT_ROLES = frozenset({})

ROW_HEIGHT_CONSTANT = None

ROW_HEIGHT_SCALE = 1

__init__()

clearCache()

paintRow(painter, per_cell_data, per_row_data, row_rect, left_edges, top_edge, col_width, row_height)

• per_row_data (dict(int, object)) – A dictionary of {role: value} for data that’s the same for all columns in the row. Note that the keys of this dictionary are PER_ROW_PAINT_ROLES - self.PER_CELL_PAINT_ROLES.

• row_rect (QtCore.QRect) – A rectangle that covers the entire area to be painted.

• left_edges (list(int)) – A list of the x-coordinates for the left edges of each column.
