change context menu for histogram item inside imageview

[azpa...@gmail.com]

Hello,

I am trying to change the context menu available when we right click on the histogram of an image view but I cannot find anywhere any reference to it. Where is created? How can I change it? 

I saw for the image itself there is a buildMenu() option which actually creates that context menu and saves it in self.menu. Is there an equivalent for the histogram somewhere? 

Kind regards,

Lavinia

to answer my own question:

 imv = pg.ImageView()

 histo_item = imv.getHistogramWidget().vb.menu.addAction("Extra action")

I expected that: imv.getHistogramWidget().item.getViewBox() would be returning the viewbox but it gives the LUTHistogramWidget... Tbh this was not intuitive to me, so if someone can explain why I would appreciate it. 

Kind regards,

Lavinia
