Menu activation event button gtk2

[vargatam77]

Hey, looking for some open minded people to finally trace down the mousebutton activation chain from click to activation to to only allow primary button to activate. No, im not going to post codes etc here, its pointless, i have lazarus 4.99 and gtk-2-8 code pulled, deep into the code of both, I have probably already found where it goes, i was able to debug button info, but im new on the linux dev side and have nonstop issues configs and makes so im hitting nonstop walls. If you are willing to help let me know, i will invite into the git repo and will try to figure it out together.
And please, don't come and tell me how its necessary and useful to enable any click to activate menus. its not. Thanks
