MATLAB: Found a potential bug in ‘listdlg’

bugfunctionlistdlgMATLABnot a bug

When typing the following code:

[w,~] = listdlg('PromptString',{strcat(['Select a wing for ' ,...
    'individual number ',num2str(indx)])},...
    'SelectionMode','single','ListString',fn);

It doesn't show the words after 'individual'

I wonder why…

Thanks,

Ziv

It wouldn't be a bug since this behavior is documented in the doc.

"If you specify the prompt as a character vector that is longer than the width of the dialog box, the prompt clips. To create a multiline list box prompt, specify the prompt as a cell array or string array. Line breaks occur between each array element. Long elements wrap to fit the dialog box."

Your prompt string is longer than the width of the box. You could try the following.

[w,~] = listdlg('PromptString',["Select a wing for ",...
    "individual number " + num2str(indx)],...
    'SelectionMode','single','ListString',"Happy");

From the documentation,

Try this

MATLAB: Put workspace data into menu and prompt someone to select it

Inorder to prompt user to select data from excel sheet.

First load the data from excel sheet into workspace, inorder to achieve this use function like readtable, readmatrix, readcell
In order to prompt user to select data, use listdlg function which create a list selection dialogue box. listdlg function only takes strings so convert the numeric data into string format using string function

As an example

data=readtable('mydata.xlsx'); % contains date, day, temperature
% is you want user to select temperature then convert temperature values into string datatype
temperature = string(data.temperature);
[indx,tf] = listdlg('ListString',temperature); %prompts user to select data
