to change the properties like border size and fill color of a statistics box in a RooPlot object I am currently doing
RooDataSet *myset = …
RooPlot *plot = …
TPaveText text = (TPaveText) plot->getAttText();
This works, but for esthetic reasons I am annoyed by the extra type casting I have to do from TAttText to TPaveText, especially since RooDataSet::statOn creates a TPaveText objecy but RooPlot::getAttText returns a TAttText object.
Is there a reason why there isn’t a RooPlot::getPaveText or equivalent?
The getAttText() style accessors are added to be able to conventiently
change the text properties of any object you added to your RooPlot
that inherits from TAttText w/o casting. Similar accessors exist for marker style, color etc. Note that you can get the TObject pointer back with the getObject()
You are of course correct that a TPaveText has additional properties,
but as in principle you any TObject inherited object can be added
to a RooPlot your request would lead to an very large number of possible
accessors of this style, so its is a bit of a balance, but your point
on statOn making TPaveTexts is a good one.
So I’ll add a TPave* accessor to RooPlot, which covers a few
more use cases than TPaveText and does allow you to access the
non-text properties of a TPaveText.
