Problem with pushButton handling - pyqgis

Question

I have made a pushButton - new window relation. Now, when I'm trying to 'link' methods with pushButtons in new window they don't react.

Here is what I wrote in metod, which opens new window in plugin:

def handleButton(self):
 self.sc = PluginConfigDialog()
 self.sc.show()
 result = self.sc.exec_()

I have also added this line in __init__:

self.dlg.pushButton.clicked.connect(self.handleButton)

But when I'm trying to add a alike action with a pushButton_2 in new window, to open another one (third window) nothing happens. Here is code I wrote:

def handleEdit(self):
 self.s = PluginEditDialog()
 self.s.show()
 result = self.s.exec_()

I also added this line to __init__:

self.d.pushButton_2.clicked.connect(self.handleEdit)

I have also added imports for this new windows and create the dialogs (after translation) and keep reference in __init__

Do you know what I'm doing wrong?

• ArMoraer: Is self.d.pushButton_2 (instead of self.dlg.pushButton_2) a typo? This might be the cause of your issue.
• W. Tom: It's not a typo. There are two dialogs in _init_: # Create the dialog (after translation) and keep reference self.dlg = PluginDialog() self.d = PluginConfigDialog() I'm not sure but if I want to refer to pushButton in second plugindialog I must import it and create a dialog and keep reference to it in _init_
• eftas: @W.Tom You can also write the listener before the line self.s.show()
• W. Tom: @eftas Sorry, but I'm not into pyqgis and I don't understand what will it change?

Here is my approach for solving this:

• In your main file import the class which creates the dialog

  from style_manager import StyleManagerDialog
  

• connect to a button which opens the new window

  # in the init function of the main class
  self.dlg.mv_pb_styles.clicked.connect(self.t1_load_styles)
  self.sub_dlg = StyleManagerDialog(self.iface)
  def t1_load_styles(self):
   self.sub_dlg.show()
   res = self.sub_dlg.exec_()
  

• In the class which creates the new dialog import qgis modules and connect to the QGIS iface

  from qgis.core import *
  from qgis.gui import *
  from qgis.utils import *
  class StyleManagerDialog(QtGui.QDialog, FORM_CLASS):
   def __init__(self, iface, parent=None):
   """Constructor."""
   super(VortexStyleManagerDialog, self).__init__(parent)
   self.iface = iface
   self.setupUi(self)
  

• in the class which creates the dialog connect to your buttons and write the functions

  self.button.clicked.connect(self.style_set_file)
  def style_set_file(self):
   filename = QFileDialog.getOpenFileName(self, u"Do Stuff!", "", "QGIS Style (*.qml);;Text (*.txt);;XML(*.xml);; All files(*.*)")
   # do something with a qgis layer 
   print self.iface.activeLayer().name()
  

I have tested this approach for QGIS 2.14.15 and it works as from me intended.
