QTableView only showing data when row selected

Hello

I have a QTableview created in Designer with the additional Python code:

Code:

---

self.tvObserverEffort.setModel(self.observerEffortModel)
self.tvObserverEffort.setSelectionMode(QTableView.SingleSelection)
self.tvObserverEffort.setSelectionBehavior(QTableView.SelectRows)
self.tvObserverEffort.hideColumn(0) # ObserverEffortId
self.tvObserverEffort.hideColumn(1) # Survey
self.tvObserverEffort.hideColumn(5) # Observer
self.tvObserverEffort.hideColumn(10) # Date
self.tvObserverEffort.setItemDelegate(QSqlRelationalDelegate(self.tvObserverEffort))
self.tvObserverEffort.horizontalHeader().setProperty("mandatory", QVariant(True))
self.tvObserverEffort.setProperty("mandatory", QVariant(True))
self.tvObserverEffort.horizontalHeader().moveSection(11,0)
self.tvObserverEffort.horizontalHeader().moveSection(12,1)
self.tvObserverEffort.resizeColumnsToContents()
self.tvObserverEffort.setWordWrap(True)
self.tvObserverEffort.resizeRowsToContents()

---

I filter the model as follows:

Code:

---

surveyId = self.effortDayModel.record(index.row()).value("SurveyId").toInt()[0]
observerId = self.effortDayModel.record(index.row()).value("ContactId").toInt()[0]
effortDate = self.effortDayModel.record(index.row()).value("WatchDate").toDate()
filter = "ObserverEffort.SurveyId = %s AND ObserverEffort.ContactId = %s AND ObserverEffort.WatchDate = '%s'" % (surveyId, observerId, effortDate.toString("yyyy-MM-dd"))
self.observerEffortModel.setFilter(filter)
self.observerEffortModel.select()
self.tvObserverEffort.show()

---

The problem that I am having is that although the TableView is showing the correct number of rows when the filter is applied, the table rows only display data when a cell in the row is selected. What am I missing ??

Thanks for any help you may have

Hello

Is anyone able to help me with this ???

Thanks

I tracked this down to a problem in my stylesheet
