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)

• Chris Papas: if i put button in the __init__ then show me no atrribute error ,why ?
• Chris Papas: AttributeError: nameplugin instance has no attribute 'dlg'
• dmh126: Now you know that connectiion is ok. Error is occuring when you try to execute this line: self.dlg.show() are you sure you want to do this there? What is that? You don't have any self.dlg object.
• Chris Papas: that error show me every time to start QGIS i have two buttons and 5 line edits what you mean self.dlg object ?
• Chris Papas: not i put now you are correct now dont show me error but my code in run1 dont excetute if i push button :( i paste you my init
