Method Details

[hide private]

_getData(self, col, feature_row, role)

Decorators:

@table_helper.data_method(Qt.DisplayRole, Qt.CheckStateRole)

_getForegroundColor(self, col, feature_row, role)

Decorators:

@table_helper.data_method(Qt.ForegroundRole)

_setData(self, col, feature_row, value, role, row_num)

Set data for the specified index and role. This method should be reimplemented in any subclasses that contain editable columns.

Parameters:

col - The column to set data for
row_data - The ROW_CLASS instance to modify
value - The value to set
value - object
role - The role to set data for
row_num - The row number

Returns: object

False if setting failed. All other values are considered successes.

Overrides: ui.qt.table_helper.RowBasedTableModel._setData

(inherited documentation)

getSelectedFeatures(self, include_pt_feats, include_custom_feats)

Returns dictionary of checked feature names. It is keyed on hypothesis entry ids and contains feature names for each hypothesis.

Parameters:

include_pt_feats (bool) - indicates that selected features that came from PT hypotheses should be included
include_custom_feats (bool) - indicates that selected features that were manually added by the user should be included

Returns: dict

dictionary of checked feature names

getSelectedExcludedVolumes(self)

Returns list of hypothesis entry ids which have excluded volumes checked.

Returns: list: list of hypothesis entry ids, which have have excluded volumes checked

toggleSelection(self, hypo_eid, feature_name)

Flips use_feature flag for a given feature.

Parameters:

hypo_eid (int) - feature's hypothesis entry id
feature_name (str) - feature name

getLastCustomFeatureNum(self)

Finds all 'custom' features and returns last feature number. For example, if custom features are ['A1', 'D11', 'R5'] last custom feature number will be 11.

updateFeatureNames(self, marker_features)

This function updates feature names in the model so that they are consistent with markers feature names. This is needed when user changes feature type using edit feature dialog. In this case only a single feature row needs to be modified.

Parameters:

marker_features - dictionary of feature marker names keyed on hypothesis entry ids.
marer_features (dict)

_getFeatureNames(self)

Returns dictionary of all feature names in the model, which is keyed on hypothesis entry ids.

Returns: dict: dictionary of feature names
