orangecontrib.tomwer.widgets.visualization.VolumeViewerOW.VolumeViewerOW

class orangecontrib.tomwer.widgets.visualization.VolumeViewerOW.VolumeViewerOW(*args, captionTitle=None, **kwargs)

Widget embedding a viewer to display reconstructed volume.

Several views are possible. One per axis or an ‘overall’ view (displaying the three axis in parallel).

By default this widget allow users to browse the volume along the ‘fast axis’ and will sample 3 slices along each axis that could be displayed. If users agrees on loading the full volume then browsing can be done along any direction.

ewokstaskclass

alias of VolumeViewerTask

handleNewSignals()

Handle new signals. In other widgets inheriting from EwoksWidget we overwrite this function to ignore any processing triggered. And we overwrite the signal to make sure the ewoks “execute_task” is called. But here display the volume is an “end node” and does not propagate the signal we are not force to do it. We can ignore the orange signal compression mechanism.
