hi All, If you deal with multivariate, multitemporal and cyclic raster data you might find interesting my multiview plugin. See screenshot of what can be done in terms of different visualizations below. The code still has some minor glitches but it is very well usable (and stable). As well here Read more…
so , here a snippet on how to use the different types of signals in PyQt: connect a signal from C++ QObject.connect(self.sender, SIGNAL(“signalName( Arg1TYPE, Arg2TYPE )”), self.slot) connect a signal from Python QObject.connect(self.sender, SIGNAL(“signalName” ), self.slot ) emit a signal in Python self.emit( SIGNAL( “signalName” ), arg1, arg2 ) emit Read more…
