Reset uitable data

Hy, i'm trying to reset the uitable of my GUI but its not working, I used:

set(handles.uitable,'Data','');

It apparently clean the data, but it also doesnt allow me to edit the uitable anymore. I had also used the function "reset":

reset(handles.uitable), But it didnt work either.

Try

set(handles.uitable, 'Data', cell(size(get(handles.uitable,'Data'))));

It worked but just with numbers, now i can't use strings in the uitable.

[Walter Roberson]

newd = get(handles.uitable,'Data');

charlocs = cellfun(@ischar, newd);

newd(charlocs) = {''};

newd(~charlocs) = {[]};

set(handles.uitable, 'Data', newd);

[Guilherne]

thanks, it really worked.

hi Walter, i have same problem. but now it has been solved with your code. May i ask what the meaning of @ischar ? newd(charlocs) = {''}; ? newd(~charlocs) = {[]}; ? thank you

[Walter Roberson]

uitable 'data' property takes a cell array, each element of which can be a string or numeric. The cellfun(@ischar, newd) runs through each cell entry and tests to see if it is string or not, returning true if it is and false otherwise. The result, charlocs, is the same size as the cell array but is true for the places that were strings and false otherwise. This logical mask is then used to set those places that were strings to be empty strings, and the negation of the logical mask is used to set the other locations to empty arrays. In this way each local is set to the empty version of what it was before, which preserves information about whether the entry was a string or not.

HI Walter Roberson. thanks for answer.. I have problem same how reset uitable. but it has been solved with your answer above....I have problem again, how to reset or remove checklist on the checkbox?. because I use the checkbox for insert data to uitable. so if we reset data in uitable, the cheklist in checkbox must be lost...

thanks..

[Walter Roberson]

If [] does not work for those, then use 0 for them. 0 means unchecked.

[aveks Gebastyan]

everything doesn't work..

   set(handles.checkbox1,0);
or
set(handles.checkbox1,'0');
or
set(handles.checkbox1,[]);

[Walter Roberson]

Are you asking about uicontrol style checkbox? If so then set their Value property to 0. set(handles.checkbox1, 'Value', 0)

I thought you were asking about uitable checkbox columns.

[aveks Gebastyan]

thanks for answare my question. Thank you so much for your explanation. God Bless You..it's work..

[aveks Gebastyan]

    set(handles.checkbox1, 'Value', 0)
