问题 As mentioned in a related answer, it is possible to get the handles of all open figures using: hFigs = findall(groot, 'Type', 'figure'); but this results in a list that contains both "old" figure and "new" uifigure handles. How can I separate hFigs into two lists, one containing only figure and the other only uifigure references? 回答1: To distinguish between figure and uifigure objects programatically, we can use a slight adaptation of what I suggested here: function tf = isUIFigure(hFigList)

Thus, I tried to change some widgets that I had developed to uifigure , and uigridlayout seems to be quite handy to replace the uix.VBox and uix.HBox from the GUI Layout Toolbox. For

问题 MATLAB provides the addlistener function. Listeners allow us to keep track of changes of an object's properties and act upon them. For example, we can create a very simple listener that will display a message in the command window when the 'YLim' property of an axes object is changed: % Example using axes ax = axes(); addlistener(ax, 'YLim', 'PostSet', @(src, evnt)disp('YLim changed')); Try panning the axes or zooming in/out and see what happens. This works fine. I need to do the same but
