Collin (1 day 23 hours ago): Seth Good point, I am using 2022b, mathworks seems to have started using CEF browsers from 2019a, best I can tell. take a look at the package com.mathworks.toolbox.matla...
Seth (2 days 16 hours ago): Collin, What version of MATLAB are you using?
Collin (7 days 22 hours ago): Seth, I have had some success executing javascript that requires no return value by executing it directly (sort of) on the org.cef.browser.CefBrowser that a...
Coo Coo (9 days 17 hours ago): FFT-based convolution is circular whereas MATLAB’s conv functions have several options (‘valid’, ‘same’, ‘full’) but unfortunately not...
Seth (9 days 20 hours ago): No luck with removing the space.
Seth (9 days 21 hours ago): The javascript code works fine running the application from the 2019b desktop version and the 2016b deployed version.
Seth (9 days 22 hours ago): I have been using this browser functionality in 2016b because it works fully in deployed applications in that version. However, because of Java 7 being flagged as a security risk, I...
Yair Altman (9 days 22 hours ago): I’ve never tested javascript callbacks, but perhaps you should try removing the extra space after the “matlab:” protocol specifier. Does it make any difference?
Seth (9 days 22 hours ago): I have been using this functionality in 2016b since it works in deployed applications and have not had a reason to need to upgrade but with java 7 being flagged as a security risk I am...
KEVIN (29 days 23 hours ago): I apologize, I intended my response to fall under ‘T’ but did not seem to work. I was referring to the bit of code posted by ‘T’ regarding the toolgroup and...
Yair Altman (29 days 23 hours ago): It is not clear from your comment which code exactly you are referring to and what you see differently in 19b vs. 20b, so I cannot assist with your specific query. In general I...
Kevin (31 days 1 hour ago): Any ideas on why this bit of code looks fine in say R2020b but produces an incorrect image in R2019b? I’m not seeing any error printouts that suggest it’s unhappy with the...
Yair Altman (49 days 23 hours ago): titleStr = char(hFig.Name); if strcmpi(hFig.NumberTitle,'on') prefix = ['Figure ' num2str(hFig.Number)]; if ~isempty(titleStr) titleStr = [prefix ': ' titleStr]; else titleStr...
T (55 days 23 hours ago): Mathworks has indeed been migrating its Java-based apps (like the PIDtuner, as you mentioned) to html-based ones (uifigures) so that they can be used in Matlab online. If you drill a bit...
Kevin (56 days 1 hour ago): Found it, findjobj utility was extremely helpful here, you can see there’s a CloseButton object there, just need to set the visible parameter to false. Easily done in the...
