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

What do you mean by the functionality of bullets? Do you want some output given as a bulleted list of text?

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?

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.

y = strcat(char(183), x);
would be easier to understand (though not necessarily faster for sure.)

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>•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
