I noticed another issue, when i rename the default node in node properties
option, then they are not renamed in the pushbutton.
In the screenshot attached I renamed default node as "123" but in the
pushbutton default is shown.
I tried debugging it and found nodetype class (namechanged function) is
getting invoked, then signal mapper is calling nodetypechanged in
nodetypemodel.cpp class but i am unable to figure the exact flow of
execution as there are a lot of files and connections.
Is there some tool which will be able to tell what functions are getting
invoked by pressing the ok button after changing name. I think that would
help in debugging.
Thanks :)
