sas.qtgui.Plotting.Slicers.BaseInteractor module

class sas.qtgui.Plotting.Slicers.BaseInteractor.BaseInteractor(base, axes, color='black')

Bases: object

Share some functions between the interface interactor and various layer interactors.

Individual interactors need the following functions:

save(ev) - save the current state for later restore restore() - restore the old state move(x,y,ev) - move the interactor to position x,y moveend(ev) - end the drag event update() - draw the interactors

The following are provided by the base class:

connect_markers(markers) - register callbacks for all markers clear_markers() - remove all items in self.markers onHilite(ev) - enter/leave event processing onLeave(ev) - enter/leave event processing onClick(ev) - mouse click: calls save() onRelease(ev) - mouse click ends: calls moveend() onDrag(ev) - mouse move: calls move() or restore() onKey(ev) - keyboard move: calls move() or restore()

Interactor attributes:

base - model we are operating on axes - axes holding the interactor color - color of the interactor in non-active state markers - list of handles for the interactor

clear_markers()
