LyX ⇒ No automatic line break in paragraph title

[sim0ne]

Hi.

I've been using LyX for quite a while now, but now i faced a problem i never had before:
in paragraph titles, there is no line break, so the title goes over the margin of the mage. same think with the title in the table of contents.

can somebody help me? thanks in advance.

Welcome,

paragraph was a strangely chosen word for a sectional heading and it leads to confusion.
In case you are putting whole paragraphs of text into paragraphs, don't.

If not, and i think you don't, can you show us a very minimal lyx example? Even better would be the export to LaTeX.

[sim0ne]

Hi.

well, i sort of HAVE to use some pretty long titles. i tried it with "normal language", and the line breaks seem to work fine. but if it's names of chemicals, for example, lyx just doesn't know where to put the break.

on some names, it gets it right, on others it doesn't.

so, here's the resulting PDF:

That was recently discussed in our german sister forum. http://golatex.de/viewtopic,p,78466.html#78466


When i have more time, i add some explanation here as well.

[sim0ne]

thanks for the link.
i do speak german, and i see that it's quite the same problem as mine. still, i'm not THAT much into latex to understand what's going on. that's the reason why i'm using LyX

so if there is a WYSIWYG kind of solution to this problem, please let me know. if you can somehow explain it in german, i could translate it so you have less work to do putting it up here on the english forum as well.

Chemical names always are a problem and there is no one fits all solution. However, there are measures you can take to make things easier. As a LyX user they would require ERT, though…

For one thing I'd use the microtype package and chemmacros in combination with chemformula. This should help in many cases already:

Adding \sloppy at appropriate places may cure the remaining problems:

[sim0ne]

wow, that's very nice. thanks a lot.

but still, the headlines are too long for the page number to show up. they should be even shorter. is that possible?

What do you mean by headlines? The header?
