My understanding is that the modifierFlag "256" means that no other modifiers are pressed. I haven't found it in the docs anywhere, but I believe that you can count on "256" meaning "no flags". Every machine I've tested this on (I've done a bunch of CGEvent stuff recently) seems to agree.Dave On Jan 16, 2009, at 2:08 PM, Alexander Reichstadt wrote:Hi,I have a phenomenon I am exploiting but unless I know for sure why it works must stop to use. The objective is to make sure that while the mousebuttons is being pressed no other modifier key is pressed, if anything is pressed the whole method return. Testing for 256 seems to work, why?NSUInteger modifierFlags = [currentEvent modifierFlags]; if (modifierFlags!=256) return;Is there some documentation that supports this test, or do I have to check for all the different keys not to be pressed instead?Thanks Alex_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
