Phil I think that it would be good to migrate the code to SmalltalkHub. Stef On 7/5/14 15:48, phil(a)highoctane.be wrote: > > On Wed, May 7, 2014 at 3:12 PM, Esteban A.

Do we migrate the code to SmalltalkHub and add some configuration? I know that Olivier told me that he uses a direct mysql driver (or I confused it with another one).

Re: [Pharo-users] Spec Tabs : how to remove proramatically a tab ?

Hi glenn We will see what ben will answer but may be this is just that some behavior is missing or not exercised yet. Feel free to push code that fix your problem.

Re: [Pharo-users] Dynamic example for spec

by Stephan Eggermont

continued A next step is the editing of existing instances. In the DOPartiesList, we need to use a NewListModel instead of the ListModel, as that understands doubleClick actions. DOPartiesList>initializeWidgets - list := self newList. + list := self instantiate: NewListModel. To edit a party, we modify addPartyBlockIn: anEditor to create editParty:in:. We set the data values and the title. In the okAction we don't have to add the party. DOPartiesList>editParty: aParty in: anEditor aParty class fields do: [ :field | (anEditor model perform: field) text: (aParty perform: field) ]. anEditor title: 'Edit ',aParty fullName. anEditor okAction: [ anEditor model partyClass fields do: [ :field | aParty perform: (field asMutator) with: (anEditor model perform: field) text ]. self refreshItems ]. In initializePresenter, we can then add an edit action. The list currently needs to know that it should handle doubleClicks, and then call a partyeditor DOPartiesList>initializePresenter + list handlesDoubleClick: true. + list doubleClickAction: [ |party edit| + party := list selectedItem. + edit := (DOPartyEditor on: party class) openDialogWithSpec. + self editParty: party in: edit]

If performance is not a very high issue, and your usage is quite simple and limited, you may want to search/test the old squeak MySQL driver and see if you can make it work and if it works with latests MySQL version. > > I read the threads about Glorp and DBXTalk, and I was left feeling a bit > confused about the best approach.
