Oh, yikes - thank you! Turns out this was a general issue affecting mouseover events inside *nested* scrollable areas, specifically. Fixed this up and verified the issue (and the fix) with both the test code and the large-fleet case.
... yes, it actually already is, I think. There's a new TooltipMakerAPI.addLabelledValue() method.
Ahh, ok - this'll be fixed for the next release, then; the fix I thought I'd made didn't cover the glow case.
Absolutely glorious, thank you sir. Ecstatic for the release, just can't bear the wait!
Wanted to make some more less pressing inquiries in the mean time:
1. There are relationship bars (can be added by method in TooltipMakerAPI), percentage bars in the fleet tab for hull and CR, and also bars with sliders in settings window. From what I've gathered, relationship bars are hardly suitable for anything but relationships themselves as they are not customizable and always show status string like ("Welcoming"), while proper bars and sliders are outside of reach of modders completely.
While I am able to worm my way around this with use of buttons, checkboxes and text fields (sadly, result looks nothing like vanilla), and other modders employed section headings for the same purpose, kinda wanted to ask you: are there any plans to give us proper, vanilla-looking bars and sliders?
2. It seems that addShipIcons() in TooltipMakerAPI is not quite ideal for the many purposes modders have come to use it for. For example, it is ill-suited for displaying ship images bigger than 128x128, and also does not render weaponry. Is there any way for me to display ships in custom panels (or, ideally, in tooltip instance) the way fleet or refit tab does them?
3. What kind of interactable buttons ship list in refit tab and hull list in blueprint tab use for entry items? Currently using area checkboxes (which can be made borderless only through color shenanigans, and that introduces its own problems), but it seems like there are proper method for borders in obfuscated code. Would it be possible for me, given the current API, to emulate vanilla ship lists precisely?
