I would like to change some properties of all tooltips in my application. I've found a suggestion to utilize the following command:

tm = javax.swing.ToolTipManager.sharedInstance; %static method to get ToolTipManager object
javaMethodEDT('setInitialDelay',tm,10000); % Increase delay to 10 seconds

However, when I insert this snippet of code into my startupFcn, it has no effect. Is there a way to implement this code in App Designer to configure the delay of tooltips?

Java methods are not supported by uifigures.

See a similar thread: https://www.mathworks.com/matlabcentral/answers/396625-how-can-i-put-a-javacomponent-in-the-app-designer#answer_393213

Unfortunately I am unaware of workaround. My apps usually contain a checkbox option in the options menu to toggle off/on tooltips. When toggled off, the app stores all component tootip text and replaces the tooltips empty chars (''). When toggled back on, the original component tooltips are restored.
