From 42dbd7956a769b37e76a905c324c3b5453e5b7f3 Mon Sep 17 00:00:00 2001 From: Martin Fitzpatrick Date: Fri, 14 Feb 2014 10:29:33 +0100 Subject: [PATCH 001/288] Adding PyQt5 compatibility (broken) Adding compatibility for PyQt5 via a shim in Qt.py. This restructures the PyQt5 libraries to match the layout seen in PyQt4, allowing it to continue to be used as drop in replacement. This works up to the point of importing, however other API changes are broken - for example the deprectation of .scale() on GraphicsItems throws an error currently. --- pyqtgraph/Qt.py | 65 +++++++++++++++---- pyqtgraph/__init__.py | 3 +- .../PlotItem/plotConfigTemplate_pyqt.py | 2 +- .../ViewBox/axisCtrlTemplate_pyqt.py | 2 +- pyqtgraph/imageview/ImageViewTemplate_pyqt.py | 2 +- 5 files changed, 58 insertions(+), 16 deletions(-) diff --git a/pyqtgraph/Qt.py b/pyqtgraph/Qt.py index 410bfd83..4c15f670 100644 --- a/pyqtgraph/Qt.py +++ b/pyqtgraph/Qt.py @@ -11,25 +11,40 @@ This module exists to smooth out some of the differences between PySide and PyQt import sys, re +PYSIDE = 0 +PYQT4 = 1 +PYQT5 = 2 + +USE_QT_PY = None + ## Automatically determine whether to use PyQt or PySide. ## This is done by first checking to see whether one of the libraries ## is already imported.
