I would like to know if there is in MATLAB some uiobject to implement the functionality of bullets.

But what (if anything) do you want the bullets to *do*? Or are you just looking for output display? In other words, would a text box suffice, if you could format the text to display a bulleted list?

I'm just looking for output display.
Yes, I could give a format to one uicontrol with a text style, would be correct! But I don't know how I can do it.

It's not great (see Walter's answer for more discussion), but this basically works:
x = {'abc';'defg';'hijkl';'mn'};
y = regexprep(x,'(.*)',[char(183),' $1']);
figure
uicontrol('style','text','position',[100,100,100,100],'string',y,'fontsize',12)
I'm assuming you have a cell array of text, one cell per bullet point.

Hi Matt,
Yes u are right.
Ok, I think that with your purpose I will can do it. For this reason, I'm going to accept this answer but If I would go farther I would see the Walter's discussion.
thanks

Walter, you're right. I can never keep track of which string functions work with cell arrays. (Plus who doesn't love the chance to mess with regular expressions!)
Mtlb Usr, glad this works for you. Another possibility would be to hack it by making an axes instead of a text box, and plotting a marker, followed by a text annotation. Messy, but I think it would work.

The more likely to work is to put char(183) at that point. That is officially "middot", a relatively small mark.
What might work is to use, e.g.,
<HTML>&bull;cccc
The <HTML> must be the first thing in the string for that particular line.
If it works it will be Unicode character 8226, which is not normally possible to put in to a uicontrol; see more discussion here

Are you interested in uitree and uitreenodes, then give a look at this undocumented uitree and the related posts on the bottom.

Hi Oleg,
I'm not interested in a tree. I think that these structures are valid when you are going to display several directories or folders.
thank you
regards
