How can one specify a cell array or string array when your message has multiple lines of text?
显示 更早的评论
If the title is confusing, then you're in the same place as me. I am attempting to create a uiconfirm figure in App Designer.
I have consulted the uiconfirm documentation page, and am having trouble with the message input arguement. The documentations says under message,
"Message to display, specified as a character vector, cell array of character vectors, or string array. Specify a cell array or string array when your message has multiple lines of text. Each element in the array corresponds to a different line of text."
My interpretation of this is that the message can indeed be a cell or string array, thus allowing it to display multiple lines. I cannot find any clarification on how one might specify that the arguement would be an array. I am attempting to pass a 1x14 cell array to the message arguement but MATLAB seems content with giving me the following error.
Error using uiconfirm (line 63)
'Message' must be a char array, string array or a cell array of character vectors.
Error in app1/UserInputConfirmationDialog (line 266)
uiconfirm(app.UIFigure,message,title, ...
Error in app1/StartButtonParamsPushed (line 350)
UserInputConfirmationDialog(app);
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 309)
Error while evaluating Button PrivateButtonPushedFcn.
I'm still somewhat new to MATLAB and I can understand that I may have interpreted the documentation wrong. Hopefully someone can offer me some clarification.

If my examples below do not help, please show us what your input variables look like.

Here's are 3 examples that all produce the same confirmation figure.
Input: Cell array
f = uifigure;
msg = {'This is line 1 of message.', 'This is line 2', '', 'Line 4.'}; %{} makes cell array
selection = uiconfirm(f,msg,'My Title')
Input: String array
f = uifigure;
msg = ["This is line 1 of message.", "This is line 2", "", "Line 4."]; %[] with dbl quotes
selection = uiconfirm(f,msg,'My Title')
Input: Char array
f = uifigure;
msg = sprintf('This is line 1 of message.\nThis is line 2\n\nLine 4.');
selection = uiconfirm(f,msg,'My Title')

Hmmm that should have worked too. That produces a cell array of strings which is what my "cell array" example does.
