Qt development in Glue

Using qt-helpers

If you are interested in working on some of the Qt-specific code, it’s important that you don’t import any code directly from PyQt4, PyQt5, or PySide. Since we want to maintain backward-compatibility with all of these, you should always import from glue.external.qt as if this was one of the Python Qt packages. For instance, instead of:

from PyQt4 import QtGui

you should do:

from glue.external.qt import QtGui

Note that for now, if the PyQt4 and PyQt5 import paths would be different, you should use the PyQt4 one, and we have provided patches in glue.external.qt to make PyQt5 backward-compatible.
