python - PySide One slot to multiple widgets -

i creating small app in python using pyside. read lines text file , display each line in separate qlineedit widget. each "entry" has 2 line edits , 2 qpushbuttons. every line add widgets. problem set signal-slot qpushbuttons, when "entries" generated, last entries qpushbuttons connects slot. may please me.

here code

class itemlogger(qtgui.qmainwindow, ui.ui_mainwindow): def __init__(self, parent = none):     super(itemlogger, self).__init__(parent)     self.setupui(self)      self.parsebossitem()     self.combobox.currentindexchanged.connect(self.parsebossitem)     self.increase.clicked.connect(self.add_subtract)   def add_subtract(self):     initial = 1     print "kajskasdjflsdkjflk"  def addrow(self, item):     self.frame  = qtgui.qframe()     self.layout = qtgui.qhboxlayout()      self.itemname   = qtgui.qlineedit(item)     self.itemname.setreadonly(true)      self.itemcount  = qtgui.qlineedit()     self.itemcount.settext("0")     self.itemcount.setmaximumwidth(40)      self.decrease   = qtgui.qpushbutton("-")     self.increase   = qtgui.qpushbutton("+")      self.layout.addwidget(self.itemname)     self.layout.addwidget(self.itemcount)     self.layout.addwidget(self.decrease)     self.layout.addwidget(self.increase)      self.frame.setlayout(self.layout)      self.verticallayout_3.addwidget(self.frame)    def parsebossitem(self):     if self.combobox.currenttext() == "item_1":         item_list = open("bossitems/random_item")         line in item_list.readlines():             self.addrow(line)      if self.combobox.currenttext() == "item_2":         item_list = open("bossitems/random_item_2")         line in item_list.readlines():             self.addrow(line) 

this because connected last entry.

here doing:

1. you add row item 1, , assign button widgets self.decrease, self.increase.
2. you add row item 2, replacing values of self.decrease, self.increase newly created widgets.
3. you connect self.increase, last added widget.

if don't need access widgets after creation, should consider using local variables (e.g. without self) , connecting signal inside addrow function.

if need keep track of widget references, add them array:

# somewhere in __init__ or in parsebossitem self.increase = []  # in addrow self.increase.append(qtgui.qpushbutton("+")) self.layout.addwidget(self.increase[-1]) self.increase[-1].clicked.connect(self.add_subtract) # , on...

to use same slot form different senders, need identify sent signal. this:

def onincrease(self):     button = self.sender()     if isinstance(button, qtgui.qpushbutton):         buttonname = button.text()         if buttonname == 'name of button 1':             self.itemcount[0].settext(str(int(self.itemcount[0])+1))         elif buttonname == 'name of button 2':             ... 

off course, assuming put each qlineedit in array self.itemcount.

---

since buttons have same name, need use approach.

# in addrow self.increase.clicked.connect(lambda: self.onincrease(itemcount))  def onincrease(self, edit):     edit.settext(str(int(edit.text()+1))
