PyQt: connecting a button in a dialog
I am writing my first PyQt program, but I have a button problem. I have read another Q&A but I have not been able to solve it.
Basically I have a main window with a menu bar. Clicking on the "actionSelect" menu item opens a new SelectFiles dialog. It contains a "ChooseDirButton" button that should open the selection directory widget and change the text "ShowPath" linedit with the selected directory.
My code looks like this:
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys
import TeraGui
class MainWindow(QMainWindow, TeraGui.Ui_MainWindow):
path = ""
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.actionSelect.triggered.connect(self.Select)
def Select(self):
dialog = QDialog()
dialog.ui = TeraGui.Ui_SelectFiles()
dialog.ui.setupUi(dialog)
dialog.setAttribute(Qt.WA_DeleteOnClose)
dialog.exec_()
def ChooseDirectory():
global path
path = str(QFileDialog.getExistingDirectory(self, "Select Directory"))
self.ShowPath.setText(path)
app = QApplication(sys.argv)
form = MainWindow()
form.show()
app.exec_()
I cannot resolve the ChooseDirectory method when the "ChooseDirButton" button is clicked. I tried to link them, but I don't understand the correct syntax. Moreover, there might be something wrong with the SelectDirectory method. I created a GUI with Qt Designer and imported it using the "import TeraGui" command.

It looks like you need to subclass your dialog, just like the main window.
I can't test it without your ui modules, but something like this should work:
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys
import TeraGui
class MainWindow(QMainWindow, TeraGui.Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.actionSelect.triggered.connect(self.Select)
def Select(self):
dialog = Dialog(self)
dialog.exec_()
self.ShowPath.setText(dialog.path)
class Dialog(QDialog, TeraGui.Ui_SelectFiles):
def __init__(self, parent=None):
super(Dialog, self).__init__(parent)
self.setAttribute(Qt.WA_DeleteOnClose)
self.setupUi(self)
self.ChooseDirButton.clicked.connect(self.ChooseDirectory)
self.path = ''
def ChooseDirectory(self):
self.path = str(QFileDialog.getExistingDirectory(
self, "Select Directory"))
app = QApplication(sys.argv)
form = MainWindow()
form.show()
app.exec_()
