[Qgis-developer] Finding QGIS Version in Python Plugin?

[Bruce, Bob (CON)]

Hi Germán:

                        Thanks for that pointer. I changed the code to:

 

        theVersionInt = QGis.QGIS_VERSION_INT

        if theVersionInt / 100 > 102: # must conform to newer API standard call

            QObject.connect(self.emitPoint, SIGNAL("canvasClicked(const QgsPoint &,\

                            Qt::MouseButton)"), self.setClipWindow)

        else: # version is 1.2 or earlier - use older API standard call

            QObject.connect(self.emitPoint, SIGNAL("canvasClicked(QgsPoint &,\

                            Qt::MouseButton)"), self.setClipWindow)

 

And now it works for all versions of QGIS.

 

            Bob

Hi Bruce, you can use the QGis class from Core module:

Hi:

            Is there a function to call to 'discover' the version of QGIS that you are running? I would like to be able to decide whether to call:

 

QObject.connect(self.emitPoint, SIGNAL("canvasClicked(QgsPoint &, Qt::MouseButton)"), self.setClipWindow)

 

or

 

QObject.connect(self.emitPoint, SIGNAL("canvasClicked(const QgsPoint &, Qt::MouseButton)"), self.setClipWindow)

 

based on the version of QGIS. This would allow me to have one version of my Image Clipper plugin.

 

Thanks,

            Bob Bruce
