I have the following challenge. I need to manipulate the controls on a page from my arduino code: hide some controls, show other controls, enable/disable timer. The way I do it is via global page variable, which value I set in my code and then read on page Preinitialize event and do something like this:
This works fine when the page just loads, but there is no way to do anything when page is already loaded.
I use ESP32 with Nextion library and control screen elements in object oriented way as outlined in examples. Only Page object has method Show. Regular controls don’t have a way to show/hide or disable.
Any other way to accomplish what I need?
