Hello,
I'm trying to generate a TableView from a list of dict my data sample is like this
data = [{'IP': '192.168.1.10', 'PRESENT_STATUS': 'NewConnection'},
{'IP': '192.168.1.108', 'FORMER_STATUS': 'NewConnection, 'PRESENT_STATUS': 'Registered'}]
My understanding of the below code is that data method gets all possible roles one after the other for each index.row() and index.col().
This means that when role == Qt.BackgroundRole and the color for the present status is defined self._base_color dict, the column gets painted.
I know that my code below should paint the entire row albeit doing it column wise.
class TableModel(QAbstractTableModel):
def __init__(self, data: Union[list, dict] = None):
super().__init__()
self.data = data or []
self._hdr = self.gen_hdr_data() if data else []
self._base_color = {'NewConnection': 'blue', }
def gen_hdr_data(self):
self._hdr = sorted(list(set().union(*(d.keys() for d in self.data))))
return self._hdr
def data(self, index: QModelIndex, role: int):
_state = self.data[index.row()]['PRESENT_STATUS']
if role == Qt.DisplayRole:
try:
col = self._hdr[index.column()]
value = self.data[index.row()][col]
except KeyError:
value = None
return str(value) if value else ""
if role == Qt.BackgroundRole and self._base_color.get(_state, False):
return QColor(self._base_color[_state])
My question is goes as such:
