General ⇒ Proof environment numbered not like I want

[thedoctor818]

I am using ntheoerem and have defined my own proof environment. But I want the proofs to (like the default) have no numbering. I have tried altering the setup to nonumber but still the proofs are numbered. Here is my MWE:

Code: Select all

Hi Michael!

You could use the nonumberplain style:

Code: Select all

Code, edit and compile here:

1
2
3
4
\theoremstyle{nonumberplain}
\def\theoremframecommand{%
        \psshadowbox[fillstyle=solid,fillcolor=red,linecolor=black]}
\newshadedtheorem{proof}{Proof}

Thanks Stefan!

That does indeed work. However, I loose the qed symbol at the end of the proof enviornment.

I tried adding the following:

Code: Select all

1
\theoremsymbol{\rule{1ex}{1ex}}
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

and that brought the qed symbol back for some of my proofs except thoose that included an enumerated list within the body of the proof.

Additionally, in thoose proofs (the ones that included an enumerated list) I see that the end of theorem symbol is not at the end of the proof but rather midway towards the end of the proof. Any way to fix this?

Thanks so very much!
