[SOLVED] [ControlP5] Tab warning GRAVE at running

in Contributed Library Questions • 4 months ago

Hi there,

I have written a program that, among other things, generate 2 tabs (controlp5 tabs).

All the features i wrote work just fine when i'm running the program but i keep getting those warning/errors messages and i want some help to understand them if you please :

28 mai 2013 12:03:54 controlP5.ControlBroadcaster printMethodError
GRAVE: An error occured while forwarding a Controller event, please check your code at controlEvent

" Why am i getting those warnings when my program works?"
Because you make a programming error, perhaps?
Apparently, you try to assign the wrong kind of object to a variable (a Tab into a variable of type Controller).

Okay thank you

PS : " Why am i getting those warnings when my program works?" by that i meant that my tabs and controllers are working just fine but i'm getting an error named GRAVE so i felt that it was overrated

Well, such error usually are stopping the program, but it looks like controlP5 is intercepting it and continuing anyway. But I think you should see where you do such assignment and try to fix it.
Trick: export your library to application, it will export the main_ihm.java file, where you can look up the line 118. Apparently, it happens in the controlEvent() function (callback?).

I solved it when i created my tabs i add .activateEvent(true) but i never handle the related controlEvent.

Hope it will help for those who will have the same problem.

Thanks again PhiLho for your patience.

Thank to you for reporting back, indeed it can be useful.
Not using controlP5 (nor other GUI libraries), I couldn't help much, just trying to push in logical directions.
