I have noticed that this problem occurs because of 'for sayac in results:' when it is removed,no problem but ı need this loop

i tried to self.btn_back.clicked.connect(lambda : self.backBtn()) which did took me back to the main UI window but then none of the buttons in that window worked :|

Change main window active tab from a dialogbox action

I have two windows in 2 separate classes. The main window and a dialogbox window. The main window contains a Qtabwidget with multiple tabs. The dialogbox has a button.
From the main window, on the click of a button the dialogbox opens. The user performs some action and clicks the save button. On the click of the button I would like the dialogbox to close, and the mainwindow to change from the initial tab to the second tab.
My problem is that I cannot get the tabwidget to change tabs on the dialogbox save button click signal.

PyQt recommends not modifying the code generated by Qt Designer, instead it creates a class that inherits from the appropriate widget. On the other hand, the save and cancel buttons must be connected to the accept and reject methods, respectively. To get the information you can use exec_() that will return a value associated to the button that you have pressed, and if it is the save button then you must change the currentIndex of QTabWidget

Is there a way to change a label of one window from another window?

I've got some code that checks which checkboxes a user clicks. Those are then put into an array (aylm). Once the user clicks the book button, a small confirmation window pops up which says are you sure you want to book these rooms. In this confirmation window, I would like the label to say are you sure you want to book (aylm)? so that all the rooms and times selected can be seen by the user. I am not sure how to go about this since I'm using one main window which connects all the smaller windows together, which you can see below in the code.

Here is my back-end program.I use cellchange to get the changed data.Is it a good idea?
from PyQt4 import QtCore, QtGui,QtSql
import sys
class StartQt4(QtGui.QMainWindow,Ui_MainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.setupUi(self)
self.db = QtSql.QSqlDatabase.addDatabase("QMYSQL")
self.db.setHostName("localhost")
self.db.setDatabaseName("test")
self.db.setUserName("root")
self.db.setPassword("")
self.q=QtSql.QSqlQuery()
if (self.db.open()):
self.showdata()
else:
print "failed"
QtCore.QObject.connect(self.tableWidget, QtCore.SIGNAL("cellChanged(int, int)"), self.changedata)
QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL("clicked()"), self.adddata)
QtCore.QObject.connect(self.pushButton_3, QtCore.SIGNAL("clicked()"), self.deldata)
QtCore.QObject.connect(self.pushButton_2, QtCore.SIGNAL("clicked()"), self.savedata)
def adddata(self):
name0 = str(self.lineEdit.text())
name1 = str(self.lineEdit_2.text())
name2 = str(self.lineEdit_3.text())
self.q.exec_("insert into player values ('%s','%s','%s')" %(name0,name1,name2))
#lastrow=self.tableWidget.rowCount()
#self.tableWidget.insertRow(lastrow)
self.showdata()
def changedata(self,row,col):
co=self.tableWidget.columnCount()
row =self.tableWidget.currentRow()
a= self.tableWidget.selectedItems()
col=self.tableWidget.currentColumn()
a=self.tableWidget.horizontalHeaderItem(col).text()
if (col < (co-1)):
b=self.tableWidget.horizontalHeaderItem(col+1).text()
t=self.tableWidget.item(row, col+1).text()
elif (col == (co-1)):
b=self.tableWidget.horizontalHeaderItem(col-1).text()
t=self.tableWidget.item(row, col-1).text()
dt=self.tableWidget.currentItem().text()
self.q.exec_("update qiu set %s = '%s' where %s = %s " %(a,dt,b,t))
def savedata(self):
self.q.exec_("insert into player1 select distinct * from player")
def deldata(self):
#self.tableWidget.clear()
row=self.tableWidget.currentRow()
print row
a=self.tableWidget.horizontalHeaderItem(0).text()
x=self.tableWidget.item(row,0).text()
self.q.exec_("delete from qiu where %s=%s" %(a,x))
self.showdata()
def showdata(self):
self.q.exec_("select * from qiu")
col=self.tableWidget.columnCount()
for i in range(0,self.tableWidget.rowCount()):
self.q.next()
for j in range(col):
x=self.q.value(j).toString()
self.tableWidget.setItem(i, j, QtGui.QTableWidgetItem(x))
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = StartQt4()
myapp.show()
sys.exit(app.exec_())
Appreciate very much
