Unified Namespace:

Provides a consistent, Qt5-compatible module layout with some minor renaming for portability.

Environment & Code-Based Selection:

Specify your preferred binding via:

• QT_API environment variable.

• Python code (early in execution).

Safe Import Hook (Optional):

Includes an import guard that:

• Detects and blocks mixed Qt binding imports.

• Emulates Qt4-style imports via Qt5-compatible monkey patching.

Simple Usage:

from os import environ
environ["QT_API"] = "pyqt5"  # or "pyqt4", "pyside", "pyside2", "pyqt6", "pyside6", to force a specific backend.
from ManyQt.QtWidgets import *
from ManyQt.QtCore import *
from ManyQt.QtGui import *

Pydroid 3 (Android):

Pydroid 3 decides before running a script whether to start it in Qt mode, by searching the script text for import PySide6, from PySide6 or the comment #Pydroid run qt. A script that only imports ManyQt is started in terminal mode, where QApplication([]) or QGuiApplication([]) crashes with Segmentation fault. Put this line at the top of your main script:

#Pydroid run qt
from ManyQt.QtWidgets import QApplication, QLabel

app = QApplication([])
label = QLabel("Hello from ManyQt")
label.show()
app.exec()

ManyQt prints a warning when it detects this situation (set MANYQT_NO_PYDROID_CHECK=1 to silence it).
