Page Layout ⇒ Problem with newtcbtheorem

[PooggaTo]

Hello everybody,

im working on my bachelor's degree and have a problem with my theorems.

A friend of mine told me i should use "\newtcbtheorem".

So i made some for every case i need.

Code: Select all

\newtcbtheorem[number within = chapter, Crefname={Definition}{Definition} ]{MyDef}{Definition}%
{fonttitle=\bfseries, enhanced, theorem number and name,
	frame code={
		\path[thick, draw] (frame.north west)  +(.5\baselineskip,0) -| +(0,-.5\baselineskip);
		\path[thick, draw] (frame.north east) +(-.5\baselineskip,0) -| +(0,-.5\baselineskip);
		\path[thick, draw] (frame.south west) +(.5\baselineskip,0) -| +(0,.5\baselineskip);
		\path[thick, draw] (frame.south east) +(-.5\baselineskip,0) -| +(0,.5\baselineskip);
	},
	left=1mm, right=1mm, top=1mm, bottom=1mm,
	colback=black!0,
	coltitle=black
}{def}

Now my problem is, when i write text, which is longer than one page, in this theorem, LaTeX doesn't make a regular page break and continue text on page margin or even page below. I can't find any solution rn, let me know if u can help me! I appreciate your help a lot

greetings, PooggaTo

Hi PooggaTo,

welcome to the forum!

Just add the breakable option, such as

Code: Select all

\newtcbtheorem[number within = chapter, Crefname={Definition}{Definition} ]{MyDef}{Definition}%
{fonttitle=\bfseries, enhanced, theorem number and name,
	breakable,
	frame code={
		\path[thick, draw] (frame.north west)  +(.5\baselineskip,0) -| +(0,-.5\baselineskip);
		\path[thick, draw] (frame.north east) +(-.5\baselineskip,0) -| +(0,-.5\baselineskip);
		\path[thick, draw] (frame.south west) +(.5\baselineskip,0) -| +(0,.5\baselineskip);
		\path[thick, draw] (frame.south east) +(-.5\baselineskip,0) -| +(0,.5\baselineskip);
	},
	left=1mm, right=1mm, top=1mm, bottom=1mm,
	colback=black!0,
	coltitle=black
}{def}

Thank you, Stefan.

I have tried this before, but I forget to add it in \tcbuserlibrary, sorry my fault.

Code: Select all

\tcbuselibrary{theorems, skins, breakable}

So now it works, but I get a new problem.

Code: Select all

\newtcbtheorem[use counter from = MyDef, number within = chapter, Crefname={Satz}{Satz}]{MySatz}{Satz}%
{fonttitle=\bfseries, enhanced, theorem number and name, breakable,
	frame code={
		\path[thick, draw] (frame.north west)  +(.5\baselineskip,0) -| +(0,-.5\baselineskip);
		\path[thick, draw] (frame.north east) +(-.5\baselineskip,0) -| +(0,-.5\baselineskip);
		\path[thick, draw] (frame.south west) +(.5\baselineskip,0) -| +(0,.5\baselineskip);
		\path[thick, draw] (frame.south east) +(-.5\baselineskip,0) -| +(0,.5\baselineskip);
	},
	left=1mm, right=1mm, top=1mm, bottom=1mm,
	colback=black!0,
	coltitle=black,
}{sat}

Now, if LaTeX made a break, the break is perfekt, but, the design change back to this:


But it should look like this:


Any ideas why does it change back and how i could fix it?

kind regards
