You have to get the 'String' value of the listbox, which will be a cell array.

currentItems = get(hListbox, 'String');

Set the row for the item you want to remove equal to[].

newItems = currentItems;
newItems(rowToDelete) = []; % Or something like that - maybe it's {}

Then send the cell array back to the listbox with the

set(hListbox, 'String', newItems)

function.

Note:

if get(hListbox,'ListboxTop') >= min(rowToDelete)

then you will want to set(hListbox, 'ListboxTop') to a different value as otherwise it will point to the wrong place or point past the end of the new list.

Thanks a lot "Image Analyst" ..

I try to use your code , it is work good and remove specific items.

But, when I want to delete the last item , listbox was deleted as a whole!!!

Pleas Help me :(

I don't know if you guys are still in this page, but I want to ask you if I want when I remove an item from the listbox so they will be renumbered automatically, can that be done? for example I have items numbered from 1 to 10, so if I delete the item 7, I want that the numbers will be renumbered. hope you can help me guys

You're going to have to use something like sscanf() to parse the number out of the line of text. Basically strip off the numbers and rebuild your list from scratch with new numbers.
