Yair Altman (1 day 4 hours ago): Don’t reparent a pre-created uitree – create it after the new figure is already shown.
Himanshu Jain (1 day 4 hours ago): My uitree is already created but it’s visibility is set false. Now I created new figure and I want to attach the already created uitree to this figure. I tried setting...
Yair Altman (5 days 0 hours ago): I don’t recommend using Matlab’s GUIDE – it is being replaced with appdesigner in recent releases, and in a few releases GUIDE will no longer be available. In...
Santiago (6 days 22 hours ago): Hi, Yahir. Your work here is excellent and very helpful for all of us. I have a doubt, is it possible to create a kind of “traffic light” in the Matlab Guide? I want to...
Nitin (15 days 18 hours ago): Thanks for the great help
Stéphane Issartel (22 days 2 hours ago): Both .mlx and .mlapp file format seem to be “Open Packaging Conventions” formatted files. See https://en.wikipedia.org/wiki/ Open_Packaging_Conventions#...
Cris Luengo (22 days 20 hours ago): Neither set(0,’HideUndocumented’,’off’ ) nor classhandle(…) work any more (testing on R2021a). However, it is possible to convert a HG2 handle to a struct, and see all the...
Yair Altman (31 days 4 hours ago): yes – assuming you created the spinner using the javacomponent function, you can modify the Position and Units properties of the component’s container handle, which...
Santiago (31 days 10 hours ago): Hi Yair. Is it possible to modify the spinner’s position (x, y, w, h) after it has been created? I’m trying to do it during a SizeChangedFcn callback. Thanks.
Yair Altman (35 days 14 hours ago): No. In the new web-based uifigures you need to use uihtml and uistyle to update the table appearance.
Santiago (35 days 14 hours ago): Hi , Yair. ¿Do the HTML options still work in the uitables created with the app designer?
Yair Altman (68 days 21 hours ago): Yes, the report is still available. You can get it here.
Luis Santiago (68 days 22 hours ago): Hi Yair. Your articles are excellent and, even now, they are still applicable. Is the uitable report still available? I’d really like getting it.
Adam D Danz (75 days 18 hours ago): Opps…. I was using the wrong syntax: MarkedClean is an EventName and I was accidentally treating it as a PropertyName. Also, ignore the “MarkedDirty” reference...
Adam D Danz (75 days 19 hours ago): Yair, thanks for your unmatched contributions to exploring Matlab under the hood. I noticed that listeners responding to MarkedClean in geoaxes throw an error even though...
