Hello, I have a question
I have a GUI figure and I want to see a text box in GUI. The text box will show what is written to the command window.
Is there a simple code for this?
Thx

Not that I'm aware of. What kind of output are you thinking of? Is there a reason why you cannot use a text box yourself and send your output there instead of the command window?

See: FEX: CmdWinTool
Key = '== Start logging:'
fprintf('%s\n', Key);
... yourCode
Final = strsplit(CmdWinTool('getText'), char(10));
Match = find(strcmp(Final, Key), 1, 'last');
New = Final(Match + 1:end);
FigH = figure;
TextH = uicontrol('Style', 'edit', ...
'Units', 'normalized', ...
'Position', [0, 0, 1, 1], ...
'String', New);
UNTESTED CODE! Just for demonstration of the method.
But it would be much smarter, to create the output in the GUI directly instead of the indirection of the command window. Prefer to collect the output in a variable by replacing e.g. disp by a modified fprintf:
function Out = fprintfDelayed(varargin)
persistent Buffer
if isdouble(Buffer) % Initialized buffer as Cell string
Buffer = {};
end
if nargin == 0 % Flush the buffer
Out = Buffer;
Stored = {};
return;
end
newStr = sprintf(vargargin{:});
newCell = strsplit(newStr, char(10));
Buffer = cat(2, Buffer, newCell);
end
Now call this like:
fprintfDelayed('Hello\n');
fprintfDelayed('World\n');
Out = fprintfDelayed
and insert the cell string into your text field.
