How to make QAbstractTableModel 's data checkable
I want to make each cell in the following code can be checked or unchecked by the user ,how to modify the code ?
according to the Qt documentation ：Qt::CheckStateRole and set the Qt::ItemIsUserCheckable might be used ,so anyone can give a little sample ?
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
class MyModel(QAbstractTableModel):
def __init__(self, parent=None):
super(MyModel, self).__init__(parent)
def rowCount(self, parent = QModelIndex()):
return 2
def columnCount(self,parent = QModelIndex()) :
return 3
def data(self,index, role = Qt.DisplayRole) :
if (role == Qt.DisplayRole):
return "Row{}, Column{}".format(index.row() + 1, index.column() +1)
return None
if __name__ == '__main__':
app =QApplication(sys.argv)
tableView=QTableView()
myModel = MyModel (None);
tableView.setModel( myModel );
tableView.show();
sys.exit(app.exec_())
Override the flags function in MyModel.
def flags(self, index)
return super(MyModel, self).flags(index)|QtCore.Qt.ItemIsUserCheckable
This says that the index in your model is checkable.
Then override the data function.
def data(self,index, role = Qt.DisplayRole) :
if (role == Qt.DisplayRole):
return "Row{}, Column{}".format(index.row() + 1, index.column() +1)
elif (role==Qt.CheckStateRole):
# read from your data and return Qt.Checked or Unchecked
return None
Finally, you need to implement the setData function.
def setData(self, index, value, role = Qt.EditRole):
if (role==Qt.CheckStateRole):
# Modify your data.
I have a Qtableview with a filter option using QLineEdit. It works ok except:
When i choose an index the filter doesn't look in the index.
Row 0 isn't visible
What i would like is to be able to export the filter results to another dataframe.
This is my code , i'm new at this son feel free to correct ;-)
import timeit

self.appendColumn(data_col)
return

Datafile = pd.read_pickle('modules/ssh/downloads/productsmaster.pkl')
df = pd.DataFrame(Datafile)
# df= df.set_index('Master_key')
self.inputfilter = inputFilter
self.tableMasterData = tableMasterData
self.df = df
self.model = PandasTableModel(df)
self.proxy_model = QSortFilterProxyModel()
self.proxy_model.setFilterKeyColumn(-1) # Search all columns.
self.proxy_model.setSourceModel(self.model)
self.proxy_model.sort(0, Qt.AscendingOrder)
self.proxy_model.setFilterCaseSensitivity(False)
self.tableMasterData.setModel(self.proxy_model)

I have been trying to update a QTableViewModel when inserting a new object that represents a row. I did follow the advise of several question in SO, but I cannot get an example to work.

As indicated in the comments you have 2 errors:
The first is when you press add because when you add a new item you have to refresh the view and that's why it's called data() method and it's where the error is shown in self.index_prop(index.column()), index_pro is a dictionary so you should use [] instead of ().
val = getattr(self.wires[index.row()], self.index_prop[index.column()])
Another error is generated by the line idx = self.ui.wires_tableView.currentIndex(), the ui does not exist and it is not necessary, sure it is a remnant of a previous code, to access wires_tableView as this is a member of the class not it is necessary to use an intermediary, you must access directly with self: idx = self.wires_tableView.currentIndex()
The above are typos and probably mark it so that the question is closed there is another error that is not, and that is the reason for my answer.
In the line self.beginRemoveRows(...) you must pass the row that you are going to remove but you are passing the row that does not exist:
row = len(self.wires)
self.beginRemoveRows(QtCore.QModelIndex(), row, row) # <---- row does not exist in the table
The solution is simple, change it by index:
def delete(self, index):
"""
Delete wire
:param index:
:return:
"""
self.beginRemoveRows(QtCore.QModelIndex(), index, index)
self.wires.pop(index)
self.endRemoveRows()

The problem I was running in, is that I am able to view the table when I use a query to fill it:
def setupModel(self):
print("-> setupModel")
# SET query
qry = QSqlQuery(self.gVar.db)
sql = "SELECT ID, name, unit, source, Import, ImportIfZero, visible FROM typeOfValue"
qry.prepare(sql)
qry.exec_(sql)
self.tableView_typeOfValues_Model.setQuery(qry)
But I found the fault, that this leads to read-only tables. It is described in the manual that it should not be done: See here
So I changed to .setTable("typeOfValue") # = Tablename
self.tableView_typeOfValues_Model = ImportSqlTableModel(self.gVar.db)
self.tableView_typeOfValues_Model.setTable("typeOfValue")
self.tableView_typeOfValues_Model.setEditStrategy(QSqlTableModel.OnFieldChange)
self.tableView_typeOfValues_Model.select()
But now I have an empty view and if I call self.lastError().text() I got the message that the table will not be found because self.database().tables() (called inside the model) brings an empty list. That means to me, that the database is not initialized correctly, but self.database() brings
PyQt5.QtSql.QSqlDatabase object at 0x042C4D30 as result.
Please, can someone give me the hint to correct subclassing QSqlTableModel. Thanks!
The problem is caused by the Qt.ItemIsEditable flag that is not enabled for the Boolean type column, this is necessary in the instruction:
if index.column() in self.booleanSet and role == Qt.CheckStateRole:
print(" checkbox changed!")
if value == Qt.Checked:
print(" Qt.Checked")
return QSqlTableModel.setData(self, index, 2 , Qt.EditRole)
else:
print(" not Qt.Checked")
return QSqlTableModel.setData(self, index, 0 , Qt.EditRole)
since it verifies that the field can be edited.
So the solution is to enable this flag, but to avoid that you can write some text we will disable the Editor through a delegate:
class ReadOnlyDelegate(QItemDelegate):
def createEditor(self, parent, option, index):
lb = QLabel(parent)
return lb
Complete Example:
import sys
from PyQt5.QtCore import QVariant, Qt
from PyQt5.QtSql import QSqlTableModel, QSqlDatabase
from PyQt5.QtWidgets import QApplication, QTableView, QLabel, QItemDelegate
class ImportSqlTableModel(QSqlTableModel):
def __init__(self, *args, **kwargs):
super(ImportSqlTableModel, self).__init__(*args, **kwargs)
self.booleanSet = [4, 5, 6] # column with checkboxes
self.readOnlySet = [1] # columns which must not be changed
self.setTable("typeOfValue")
self.setEditStrategy(QSqlTableModel.OnFieldChange)
self.select()
def data(self, index, role=Qt.DisplayRole):
value = super(ImportSqlTableModel, self).data(index)
if index.column() in self.booleanSet:
if role == Qt.CheckStateRole:

else:

return QSqlTableModel.data(self, index, role)
def setData(self, index, value, role=Qt.EditRole):
if not index.isValid():
return False
if index.column() in self.booleanSet:

val = 2 if value == Qt.Unchecked else 0
return QSqlTableModel.setData(self, index, val, Qt.EditRole)
else:
return False
else:
return QSqlTableModel.setData(self, index, value, role)
def flags(self, index):
if not index.isValid():

if index.column() in self.booleanSet:
return Qt.ItemIsUserCheckable | Qt.ItemIsEnabled | Qt.ItemIsEditable
elif index.column() in self.readOnlySet:
return Qt.ItemIsSelectable | Qt.ItemIsEnabled
else:
return QSqlTableModel.flags(self, index)
class ReadOnlyDelegate(QItemDelegate):
def createEditor(self, parent, option, index):
lb = QLabel(parent)
return lb
if __name__ == '__main__':
app = QApplication(sys.argv)
db = QSqlDatabase.addDatabase("QSQLITE")
db.setDatabaseName("/path/of/your_database.db")
if not db.open():
sys.exit(-1)
model = ImportSqlTableModel()
w = QTableView()
w.setModel(model)
for col in model.booleanSet:
w.setItemDelegateForColumn(col, ReadOnlyDelegate(w))
w.show()
sys.exit(app.exec_())
The fault regarding the different QSqlDatabase object's was in the call of the subclassed QSqlTableModel. It must be assignedModel = YourSubclassedTableModel(db=your_open_database_object) if the source is a physical db. If the database is in memory db.setDatabaseName(':memory:') then this db is the default db and will be used inside the model. The docs don't mention that. In the Qt manual you will find:
QSqlTableModel::QSqlTableModel(QObject *parent = Q_NULLPTR, QSqlDatabase db = QSqlDatabase())
Creates an empty QSqlTableModel and sets the parent to parent and the database connection to db. If db is not valid, the default database connection will be used.

Thanks !
You can use the convenience method data of QModelIndex. It returns a QVariant. Just convert it to something you'd use, like a QString with .toString:
print 'selected item index found at %s with data: %s' % (it.row(), it.data().toString())
By the way, QListView.clicked will give you the index. Unless you have multiple selection, or override the default selection behavior, it will be the only selected item. You don't need to loop over selectedIndexes():
#QtCore.pyqtSlot(QtCore.QModelIndex)
def on_treeView_clicked(self, index):
print 'selected item index found at %s with data: %s' % (index.row(), index.data().toString())
