Yes, Qt-Creator is a C++ IDE, with little support for other languages but since version 2.8.0 a quite basic python support has been added.
That said you can use Qt-Designer (the form building tool), Qt-Translator (the translate tool), etc... easily with python.
There are two Qt-Python bindings right now, the GPL/Commercial dual licensed PyQt, and the LGPL PySide. I have used PyQt for a long time and I'm a happy user, I also have tried PySide but it looks less mature to me. If your license requirements allow you I'd go for PyQt.
Just desing your interface in Qt-Designer and convert it to python file executing pyuic4.
pyuic4 editorFrame.ui -o editorFrame.py
then you can import it from your main class, in this case i'm using a QMainWindow:
import sys from PyQt4 import QtGui from editorFrame import Ui_MainWindow class Editor(QtGui.QMainWindow): def __init__(self): super(Editor, self).__init__() self.ui=Ui_MainWindow() self.ui.setupUi(self) self.show() def main(): app = QtGui.QApplication(sys.argv) ex = Editor() sys.exit(app.exec_()) if __name__ == '__main__': main()
With the release of Qt Creator 2.8 things are changing. It now natively supports Python for code editing and there are few Python-based features.
An editor specific for Python was added, with highlighting and indentation, and a Python class wizard
