So simple, and in conjunction with David's recent zoom in/out/normal (+/-/=) bindings, it immediately makes clear what's going on with the hot spots, and shows up the existing mistakes. Everyone designing clickable instruments will benefit from this, so I think your patch should go into CVS permanently.

The toggling bit was mostly a joke. :) This is really only useful to people designing and debugging panels, and they're not likely to decide to do that in the middle of a long flight. They'll start up fgfs with a --prop:/sim/panel-hotspots=1 on the command line, edit their panels, and do a "reset" to see their changes. Unless there are applications for this feature that I don't see, they'll never want to turn the feature on and off interactively. There are a limited number of keys available. IMHO, panel hotspots aren't important enough to a general user to justify getting a key assigned to them by default. As you said, a menu option would make a lot more sense. Andy -- Andrew J.

That's not a bad idea. It shouldn't be that hard, actually. Just draw a final layer around the hotspots with some OpenGL lines. The existing layer offset code would insure it gets drawn on top of the rest of the panel, and the matrix environment is already set up so you can draw 2D panel coordinates directly.

Re: [Flightgear-devel] Clickable 3D panel
How hard would it be to have a property that toggles hotspot visibility? It'd be nice to be able to turn it on and have yellow rectangles show up on the hotspots...or something like that.

Heh, hard to argue with that. Indeed, there was no check for panel visibility in the input code. I guess we've never noticed because nothing was fighting for the same real estate in the past.

Are you sure? I thought this might be it too, and tried tracking it down. The 3D panels are loaded through the model code, and never get a chance to register themselves as the "current_panel" object in globals. Is there an invisible 2D panel loaded from somewhere else? FWIW, I still haven't been able to duplicate the rogue mouse click problem. Well, I'll put it this way: If I turn the 2D panel on and off with "P" while flying "--aircraft=c172-3d", and note where a particular button is, and then turn it off so that only the 3D panel is visible, I can still click where the 2D button was as well as where the 3D button is visible. Clicking in either place has the same result of activating the feature. As I said, if the position of one of these invisible 2D hot-spots obscures a 3D hot-spot, then the 3D one appears not to be working, until you change view direction a bit or zoom so it is in a different area of the screen. - Julian ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
