KEVIN (10 days 1 hour 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 (10 days 1 hour 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 (11 days 3 hours 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 (30 days 1 hour ago): titleStr = char(hFig.Name); if strcmpi(hFig.NumberTitle,'on') prefix = ['Figure ' num2str(hFig.Number)]; if ~isempty(titleStr) titleStr = [prefix ': ' titleStr]; else titleStr...
T (36 days 1 hour 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 (36 days 3 hours 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...
Kevin (37 days 1 hour ago): I’m interested in removing the (X) close button from figures added to the Toolstrip. There’s a lot of functionality that can be programmed into docked figures, effectively...
Yair Altman (37 days 18 hours ago): @Paul – There must be a way to use a toolstrip in uifigures, because many Matlab apps use uifigures with a toolstrip. But I have not [yet] discovered how to add a...
Paul (38 days 0 hours ago): Is there a way to intergrade the toolstrip or toolgroup (java based) to the uifigure? I am trying to figure out if I should go for the undocumented toolgroup or App Designer. App...
Yair Altman (51 days 23 hours ago): @Luis – I discuss adding a close button to uitabs here: https://undocumentedmatlab.com /articles/uitab-colors-icons-i mages Note that it might or might not work, depending...
Luis Santiago (52 days 22 hours ago): Hi Yair, is it possible to add a small button next to the tab title to remove it? Kind of like the little “x” on the side of a browser tab. Thanks.
Yair Altman (55 days 20 hours ago): In R2020a or thereabout, the builtin com.mathworks.mlwidgets.html.H TMLBrowserPanel object stopped displaying webpages. Instead, we can use the builtin...
Yair Altman (57 days 1 hour ago): Starting in R2022b the legacy @ syntax has changed from a warning to an error. Classes that use the legacy syntax generate a run-time error and no longer run.
Jeremiah Sullivan (57 days 2 hours ago): For what its worth, I am still getting that same “undocumented syntax” warning in 2022a. I really hope they don’t create another breaking change…
SKM (78 days 20 hours ago): It is 10 years since the original article, but I would like to bring to attention that such issues have not yet been resolved. For example, programmatically opening and closing files in...
