Running script converted from PyQtDesigner on PyQGIS

Question

I converted a .ui file of a project built on PyQtDesigner into a file .py. In an external IDE, the code works and the dialog window shows, while on the Python console in Qgis doesn't work. Here is the code.

# -*- coding: utf-8 -*-

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(553, 419)
        ...
    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        ...
    

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Form = QtWidgets.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

I think the problem is the row if __name__ == "__main__": but I don't know how to resolve this. Any Ideas?

Answer 1

When using the Python console, it seems that the __name__ variable is set to "__console__", even if you execute a script.

I guess you're just testing in the console, so you could just change the if to:

if __name__ == "__console__":

(Also small warning; sys.exit(app.exec_()) will close QGIS).
