Date: Sun 23-Aug-1989 17:17:00 From: Unknown Subject: mutiTargets Hello there! I am having difficulties figuring out how to let an object send ddifferent messages to other objects at the same time. What I want is something like a popUpList so that when the mouse goes down, the button send a message pop: to the popUpList and when the mouse goes up, the popUpList send a setTitle: to the button and at the same time notify another object that the button has changed its title. What I can think of is that I can rewrite setTitle: so that it also notifies the object I want to notify. I think it should work though I have not tried it yet. I feel there should be better way to set mutiple targets for an object. Please let me know if you have better ideas. Thanks in advance. --yufeng tsui@silver.bacs.indiana.edu >From: tsui@silver.bacs.indiana.edu (Yufeng Tsui)

First, have action and target fields for all of you want to do. id target1,target2,target3; char action1[255],action2[255],action3[255]; // used char a[255] instead of SEL a because we need to allocate the memory then have methods to set these - setTarget1:anObject { target1 = anObject; return self; } etc - setAction1:(SEL)action { strncpy(trncpyctaction1, return self; } etc. Then in your method that sends everything, just call it for all you want sequentially; [target1 @selector(action1)]; [target2 @selector(action2)]; [target3 @selector(action3)]; This should be easily implemented.
