ATM I use a grid of images within a panel - but how do I detect mouseovers? How do I connect the hoverable components? Other way around I could use buttons, but then I did not find a way how to use images with them. What is the smartest elementa way to build a scrollable picture gallery with hittest?
I think you could achieve that using a Taskable component on an Image widget. Have a look at the help patch called “HowTo Assign Tasks to Widgets”, it shows how you can assign a task to widgets in a loop.
