Thank you.

That fixed the problem with that example script, but I've encountered a different problem.

I want to create a TButton which contains a TLatex object. When I create a canvas with a single button and then draw a latex object within the button, the latex is NOT visible. But, if I run nearly the exact same script, except this time I draw a graph inside the button along with the latex object both the graph and the latex as displayed as I would expect.

I've attached a script which demonstrates.

Hi Dylan,

Your observation is correct. To have this macro working as described, the line:
should be added. Please see the attached macro but1.C.

The TButton documentation will be changed accordingly.

Cheers, Ilka
