For GUI programming I often use Python bindings for Qt.
There are two competing bindings, PySide and PyQt.
Ideally I like to have applications that can use either. This way, if I get a
problem I can try with the other bindings: if I still get the problem, then it
is probably me; but if I don't it may be an issue with the bindings.
But working with both means that my imports are very messy. Here's a tiny
example:
if PYSIDE: # bool True -> Use PySide; False -> Use PyQt5
from PySide2.QtCore import Qt
from PySide2.QtGui import QIcon
from PySide2.QtWidgets import (
QDialog, QFrame, QGridLayout, QLabel, QLineEdit, QPushButton,
QVBoxLayout)
else:
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QIcon
from PyQt5.QtWidgets import (
QDialog, QFrame, QGridLayout, QLabel, QLineEdit, QPushButton,
QVBoxLayout)
The PYSIDE constant is imported from another module and is used for all .py
files in a given project so that just by changing PYSIDE's value I can run an
entire application with PySide2 or with PyQt5.
But I'd really rather just have one lot of imports per file.
One obvious solution is to create a 'Qt.py' module that imports everything
depending on the PYSIDE switch and that I then use in all the other .py files,
something like this:
from Qt.QtCore import Qt
from Qt.QtGui import QIcon
... etc.
But I'm just wondering if there's a nicer way to do all this?
