PyQt5 Basic Window
We’re going to create a basic window in PyQt5.
from PyQt5 import QtWidgets
It imports the
QtWidgets module so that we have access to the graphical user interface.
app = QtWidgets.QApplication(sys.argv)
It creates an application object that has access to the event loop.
windowExample = QtWidgets.QWidget()
We then need to create a
QtWidget, because we’re going to use that as our top-level window and it has everything that we want.
windowExample.setWindowTitle('Basic Window Example')
setWindowTitle sets the window a title and it could be called whenever you need it.
It is needed to show the window.
We need to start that event loop by using the
If we don’t do this, the program will run straight through because it won’t keep running back on itself and this event loop here is waiting for events from us to run there.
Now we’re going to put all of that in a function which could be called to start our window running.
PyQt5 Change Window Size
If we would like to change the size of the window, we could use
setGeometry() method of window widget.
windowExample.setGeometry(0, 0, 400, 400)
setGeometry() method takes 4 integers as input argument that are
- X coordinate
- Y coordinate
- Width of the frame
- Height of the frame
Therefore, the example window size is
400 x 400 pixels.
PyQt5 Add Window Icon
It sets the window icon to be
python.jpg. The parameter of
setWindowIcon method is
QIcon object from
