Basic QT5 Help

Olivermadsen

Can someone please help me understand why this code isn't running? I am very new to QT5. I get the following error messages (I am running in pycharm):
Traceback (most recent call last):
File "/Users/oliverm/PycharmProjects/Plural-Sight /Basic Structure/1.py", line 26, in <module>
dialog = HelloWorld()
File "/Users/oliverm/PycharmProjects/Plural-Sight /Basic Structure/1.py", line 18, in init
layout.addWidget(label)
TypeError: addWidget(self, QWidget, stretch: int = 0, alignment: Union[Qt.Alignment, Qt.AlignmentFlag] = 0): first argument of unbound method must have type 'QBoxLayout'
Code:

class HelloWorld(QDialog):
def init(self):
QDialog.init(self)

    layout = QVBoxLayout

    label = QLabel
    line_edit = QLineEdit()
    button = QPushButton("Close")

    layout.addWidget(label)
    layout.addWidget(line_edit)
    layout.addWidget(button)

    self.setLayout(layout)

app = QApplication(sys.argv)
dialog = HelloWorld()
dialog.show()
app.exec_()

@Olivermadsen

    layout = QVBoxLayout

    label = QLabel

I use PyQt/Python. Unless I am wildly mistaken, you can't write those, this is not C++! I would assume those set the label to the function, they do not call the function.

    layout = QVBoxLayout()

    label = QLabel()

Does that remove your errors? You cannot lazily omit the () like you can in C++ ( layout = new QVBoxLayout, which I don't much like anyway), put them in always.

@JonB Thanks Jon! works perfectly.
