Qcombobox everytime i choose a name it prints all the name i have on my database this is my code

[A Former User]

self.query = QSqlQuery("SELECT name FROM test_table")
self.comboBox = QComboBox(self)
self.comboBox.currentIndexChanged.connect(self.selectionchange)
#
while(self.query.next()):
self.comboBox.addItem(self.query.value(0).toString())
#
self.show()
def selectionchange(self):
for count in range(self.comboBox.count()):
print self.comboBox.itemText(count)

i want to display only the name i choose how to do it?

@Gelo Use currentIndexChanged signal and donot use the loop.

@p3c0 how will i write it?

[A Former User]

@p3c0 What loop? the while or for?

[p3c0]

@Gelo Check this example:

In the similar way you connect to the currentIndexChanged signal and get the selected index text in the connected slot.
