<!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body text="#000000" bgcolor="#FFFFFF"> Hi, I have this situation where an objectA can emit event with a default argument (self): <blockquote> <pre>FilePreviewMorph>>doubleClick: event localPosition: position self triggerEvent: #doubleClick with: self </pre> </blockquote> And the listening objectB wants to be notified with a different argument (fileEntry) <blockquote> <pre>fileView when: #doubleClick send: #open: to: self with: fileEntry]. </pre> </blockquote> However when the event is triggered in objectA the optional prefered argument by objectB (fileEntry) is not used. It is still the self argument. Is it the expected behavior? The behavior is revealed here: <img src="cid:part1.eWXW1oWU.pn80dA0v@free.fr" alt=""> arguments contains the fileEntry but it is ignored as show the value of argsToUse. Change in method bellow adjust this behavior. Not sure it is what is expected. <pre>collectArguments: anArgArray "Private" | staticArgs | staticArgs := self arguments. ^(anArgArray size = staticArgs size) ifTrue: [staticArgs asNewArra] ifFalse: [(staticArgs isEmpty ifTrue: [ staticArgs := Array new: selector numArgs] ifFalse: [staticArgs asNewArray] ) replaceFrom: 1 to: (anArgArray size min: staticArgs size) with: anArgArray startingAt: 1] </pre> <pre> </pre> Thanks Hilaire <pre class="moz-signature" cols="72">-- <a class="moz-txt-link-freetext" href="http://mamot.fr/@drgeo">http://mamot.fr/@drgeo</a></pre> </body> </html>
