Subclassing Float?

by Ch Lamprecht

Hello, I tried to build a subclass of Float without success. More precisely, I did not find out how to build instances from it. Is subclassing Float something I should not do? I am trying to build objects, that represent Audio frequencies. They should behave like Floats but have some additional methods like 'addCent: anOffset' or 'deltaCent: aFrequency' (cent refers to a logarithmic scale used to express frequency relations). Cheers, Chris

I'm using Pharo-1.0-10508-rc2. And, yes, I was trying to "do" a comment.Â Silly me. Thanks for thinking of the obvious (to everyone but me).Â Works fine now.

But: this method is kind of useless, as it just dispays the html by doing: (StringHolder new contents: doc) openLabel: url. We should remove that method.

Re: [Pharo-users] Modal Dialogs

by StÃ©phane Ducasse

Dear Keith We know that the documentation is not the one we would like. Now I will try to explain inn three sentences how you can find the answer to your question now. - Open the message name tools (in tools) type modal, modal: - Have a look at implementors of openModal: - Have a look at senders of openModal: Morph>>openModal: aSystemWindow "Open the given window locking the receiver until it is dismissed. Answer the system window. Restore the original keyboard focus when closed." here is an example MCMergeResolutionRequest>>viewPatchMerger "Open a modal diff tools browser to perform the merge." |m modalMorph| m := (PSMCMergeMorph forMerger: self merger) fromDescription: 'Working copy' translated; toDescription: messageText. modalMorph := (UIManager default respondsTo: #modalMorph) ifTrue: [UIManager default modalMorph] ifFalse: [World]. modalMorph openModal: ( m newWindow title: messageText). ^m merged So there are ways to find information. Now do not hesitate to ask any question to the list. Stef PS: BTW I did not either how to open a model widget. Now I know :) On Feb 18, 2010, at 11:57 PM, Dr. Keith A.
