obtain the number of rows of qtablewidget in pyqt - pyqt

Question

I want when I click on select botton in QTableWidget(tblbimar) give me the same number of rows(QTable).
But when I click on "select" button nothing happen!
Of course I tried whether the signal "tbl_bimar_row" is sent or not؟(it work correctly)

class groupbutton(QWidget):

self.parent = parent
btnselect = QPushButton("select")
layout = QHBoxLayout()
layout.setContentsMargins(0,0,0,0)
layout.setSpacing(5)
layout.addWidget(btnselect)
self.setLayout(layout)
self.connect(btnselect,SIGNAL("clicked()"),self.return_row)
def return_row(self):
widget_pos = QtGui.qApp.focusWidget()
index = self.parent.indexAt(widget_pos.parentWidget().pos())
# OR index = self.parent.indexAt(widget_pos.pos())
if index.isValid():
self.tbl_bimar_row.emit(index.row())

print(self.tblbimar.item(row,1).text())
def get_bimar(self):
data = [['1','2','3','4','5'],['6','7','8','9','10']]
for row in data:
inx = data.index(row)
self.tblbimar.insertRow(inx)
self.tblbimar.setItem(inx,0,QTableWidgetItem(row[0]))
self.tblbimar.setItem(inx,1,QTableWidgetItem(row[1]))
self.tblbimar.setItem(inx,2,QTableWidgetItem(row[2]))
self.tblbimar.setItem(inx,3,QTableWidgetItem(row[3]))
self.tblbimar.setItem(inx,4,QTableWidgetItem(row[4]))
selbtn = groupbutton(parent=self.tblbimar)
selbtn.tbl_bimar_row.connect(self.bimar_select)
self.tblbimar.setCellWidget(inx,5,selbtn)
# self.tblbimar.setItem(inx,5,QTableWidgetItem(smart_text(row[0])))
self.tblbimar.resizeColumnsToContents()
self.tblbimar.resizeRowsToContents()
thank you

I changed the above code as the following and it worked:
class groupbutton(QWidget):
tbl_bimar_row = pyqtSignal(int)
def __init__(self,parent=None,app=None):
super(tblbutton,self).__init__(parent)
self.parent = parent
self.app = app
...
...
def return_row(self):
widget_pos = self.app.focusWidget()
index = self.parent.indexAt(widget_pos.parentWidget().pos())
self.tbl_bimar_row.emit(index.row())
class Jarahi_add(QDialog,Ui_My_Form):
...
...
def get_bimar(self):
if data:
for row in data:
...
...
selbtn = tblbutton(parent=self.tblbimar,app=self)
selbtn.tbl_bimar_row.connect(self.bimar_select)
self.tblbimar.setCellWidget(inx,5,selbtn)
