Basic Example

Basic Qt tutorial.

import sys
from qtpy import QtWidgets

app = QtWidgets.QApplication([])

Create a widget, populate it with a layout, then add a label with some text:

w = QtWidgets.QWidget()
w.setFixedSize(300, 200)

layout = QtWidgets.QVBoxLayout(w)
label = QtWidgets.QLabel("Hey there!")
layout.addWidget(label)

Show the widget so it’ll render right after this text:

w.show()

If you have a QApplication.exec_() call at the end of your example script (so it can be run as-is from the command line), qtgallery disables the Qt event loop execution to prevent an indefinite loop.

app.exec_()
