vgSrcAssoc(source, association);
‘vg’ is our product code
‘Src’ is the placeholder of the source instance
‘Assoc’ is the placeholder of the Association to be made
Example
/*declare variables*/
vgChannel *channel;
vgWindow *window;
/*get a pointer to the existing instance created thru the ADF*/
channel=vgGetChan(0);
window=vgGetWin(0);
/*associate the window with the channel*/
vgChanWin(channel, window);
vgAddSrcAssoc(source, association);
‘vg’(I think you’ve got it now)
‘Add’ is the action adding another association to our source
‘Src’ is the placeholder of the source instance
‘Assoc’ is the placeholder of the Association to be added
Example
/*declare variables*/
vgChannel *channel;
vgObserver *observer;
/*get a pointer to the existing instance created thru the ADF*/
channel=vgGetChan(0);
observer=vgGetObserv(0);
/*add the observer to the channel*/
vgAddObervChan(observer, channel);
vgRemSrcAssoc(source, association);
‘Rem’ is the action: removing an association from our source
‘Src’ is the placeholder of the source instance
‘Assoc’ is the placeholder of the Association to be removed
Example
/*declare variables*/
vgChannel *channel;
vgObserver *observer;
/*get a pointer to the existing instance in ADF*/
channel=vgGetChan(0);
observer=vgGetObserv(0);
/*remove the channel from the observer*/
vgRemObservChan(observerl, channel);
vgGetSrcAssoc(source, index);
‘Get’ is the action: getting the handle of an association to our source.
‘Src’ is the placeholder of t
