I have many components in this overview with mouseover text defined. I’ve placed a transparent rectangle over an area of the window that the user can click on to get more details for that sub-area and it directs to another window. My question is, is there any way to get the mouseover text for the c…

[image] amarks: Is that consuming the mouseover event? Yes, that will consume the event. I would expect any unconsumed event to pass to the parent, not necessarily a component below the rectangle. You can deliberately add listeners to that rectangle that repackage the event for the underlyi…

Wow… that seems like alot of work for something so simple. [image] Using the Paintable Canvas as a Glass Pane Ignition This is a tutorial I've wanted to do for some time because the glass pane is by far the most versatile Ignition tool I have ever developed. …

I haven't had to do much of this myself. I'll let others dig deeper with you.

Possibly 'EventDelegateDispatcher' is what you want: [image] Vision: Button Template Ignition For another approach, you can lean on our built in EventDelegateDispatchers class to automatically forward events (of certain types/all types) from a child component t…

I may need some more direction. What exactly do I do with that? Haven’t done much with listeners

On your transparent rectangle (in the actual window) you'd create delegating listeners once (propertyChange, event componentRunning with a value of True). They would 'clone' the events that the rectangle is consuming and "forward" them down to the lower component. The snippet I have in the linked th…

So I have to create a delegating listener on every instance of my transparent button to pass the events down? I can’t just do it once on the template? I’ve added the script to my library. How would I call it? Like this? if event.propertyName == 'componentRunning': Navigation.addForwardingEventLis…

[image] amarks: every instance of my transparent button to pass the events down? Yes, because your transparent button is the one that's consuming the events. You could, in theory, go the opposite direction - but that way lies madness. Imagine a script where the template instance looks at whe…

Ya, I was not thinking that “up” would be better than the “down” that was proposed - I was just unsure if the listener could live inside the template instead of on each template instance. Anyway, [image] amarks: I’ve added the script to my library. How would I call it? Like this? if event.pro…

In your project library: from com.inductiveautomation.factorypmi.application.components.util import EventDelegateDispatcher KEY_EVENT_MASK = EventDelegateDispatcher.KEY_EVENT_MASK MOUSE_EVENT_MASK = EventDelegateDispatcher.MOUSE_EVENT_MASK FOCUS_EVENT_MASK = EventDelegateDispatcher.FOCUS_EVENT_MAS…
