Addition button in QGIS plugin form

Question

I want to create PYQGIS plugin and for my task i need my QGIS GUI form to have one more button except to original button ok.

the additional button to do something and original button to do something else for my script.

first i add new button in initGui :

def initGui(self):
    icon_path = ':/plugins/twoobutton/icon.png'
    self.add_action(
        icon_path,
        text=self.tr(u'twoobutton'),
        callback=self.run,
        parent=self.iface.mainWindow())
    self.dlg.pushButton.clicked.connect(self.run1)

and after I create new def run1:

def run1(self):
    self.dlg.show()
    result = self.dlg.exec_()
    if result:
        myvar = str(self.dlg.lineEdit_5.text())
        if myvar==1000:
            text1='hello'
            text2='world'
            self.dockWidget.dockWidgetContents.lineEdit.setText(str(text1))
            self.dockWidget.dockWidgetContents.lineEdit_2.setText(str(text2))
        pass

update :

class fff:
    """QGIS Plugin Implementation."""

    def __init__(self, iface):
        self.dlg = fffDialog()
        self.dlg.pushButton.clicked.connect(self.run1)

        """Constructor.

        :param iface: An interface instance that will be passed to this class
            which provides the hook by which you can manipulate the QGIS
            application at run time.
        :type iface: QgsInterface
        """
        # Save reference to the QGIS interface
        self.iface = iface
        # initialize plugin directory
        self.plugin_dir = os.path.dirname(__file__)
        # initialize locale
        locale = QSettings().value('locale/userLocale')[0:2]
        locale_path = os.path.join(
            self.plugin_dir,
            'i18n',
            'fff_{}.qm'.format(locale))

        if os.path.exists(locale_path):
            self.translator = QTranslator()
            self.translator.load(locale_path)

            if qVersion() > '4.3.3':
                QCoreApplication.installTranslator(self.translator)


        # Declare instance attributes
        self.actions = []
        self.menu = self.tr(u'&ffffff')
        # TODO: We are going to let the user set this up in a future iteration
        self.toolbar = self.iface.addToolBar(u'fff')
        self.toolbar.setObjectName(u'fff')

But if I click on pushbutton then don't show me anything. How to fix that?

Answer 1

Just put self.dlg.pushButton.clicked.connect(self.run1) in __init__ not in initGui().

def __init__(self, iface):
    # some code
    self.dlg.pushButton.clicked.connect(self.run1)
