I created a dbms and also create my desire widget but now I can't connecting the buttons and the dbms. Here the code I
progress.
import mysql.connector as mc

Form.setObjectName("Form")
Form.resize(511, 447)
self.label_3 = QtWidgets.QLabel(parent=Form)
self.label_3.setGeometry(QtCore.QRect(110, 100, 281, 241))
self.label_3.setText("")
self.label_3.setObjectName("label_3")

def move_previous(self):

cursor.execute("SELECT Xpoint FROM {}".format(tablename))
self.result= self.mycursor.fetchall()
print(self.colcount.Xpoint)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.previous.setText(_translate("Form", "Previous"))
self.next.setText(_translate("Form", "Next"))

self.point2.setText(_translate("Form", "Y_Point"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec())
Expecting that my button will move base on my data on database and will show the save img on that data on that col.
