Accessing Image/Overlay data in FSLeyes from a plugin script

I am trying to figure out how to access the data from an image loaded in FSLeyes.

I tried to look at how it is done in the spinalcordtoolbox plugin This script used commands such as: selected_overlay = displayCtx.getSelectedOverlay() and overlayList.append(image)

How is it possible to access the objects displayCtx and overlayList?

When I try to use them in my plugin script, I get an error saying that they are not defined.

Here’s my code for the plugin script:

import_ wx import fsleyes.controls.controlpanel as ctrlpanel import fsleyes

class Ads_control_v1(ctrlpanel.ControlPanel):

def __init__(self, *args, **kwargs):
    ctrlpanel.ControlPanel.__init__(self, *args, **kwargs)
    sizer = wx.BoxSizer(wx.VERTICAL)
    self.SetSizer(sizer)
    sizer.Add(wx.StaticText(self, label='Ads_plugin_v1_controls'),
              flag=wx.EXPAND, proportion=1)

    adsButton = wx.Button(self, label = "Ads_pushbutton")
    adsButton.Bind(wx.EVT_BUTTON, self.onAdsButton)
    sizer.Add(adsButton, flag=wx.SHAPED, proportion=1)


def onAdsButton(self, event):
    print(overlayList) # NameError: name 'overlayList' is not defined
    print(fsleyes.overlay.OverlayList.overlays) # This is not working



@staticmethod
def supportedViews():
    from fsleyes.views.orthopanel import OrthoPanel
    return [OrthoPanel]

I contacted the FSL developers via their mailing list about this issue. Here’s the link to their response : https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=ind1902&L=FSL&F=&S=&X=9164C4158CCC55B25D&Y=stoyan.asenov.400%40gmail.com&P=216512

They changed this API so I’m not sure about it, have you tried to look if the displayCtx isn’t being passed as the parameter on the *args or **kwargs of your constructors ? That would be a reasonable way to pass these parameters so I guess they might use that. You can also ask that in their mailing list or repository because they probably now that and will be able to answer immediately.
