In ContactEditor>>openModal, Contact objects are associated to TextEntries. So on OK the data in the fields are passed to #setText: selectors (whether it's an add or edit - ContactEditor doesn't know the workflow).

The onOK: block is just used to add the Contact object to the database. In case of an edit, the edited Contact is already in the database so there's nothing to do.

Can you explain how changes (via Edit button) are saved? The addButtonClick method uses onOK:aBlock, but editButtonClick doesn't.

1. ContactListEditor is not a Window but an Object subclass.

The window is created by #openInWindowLabeled:. So in ContactListEditor>>open
....
mainWindow := (content openInWindowLabeled: 'Contacts') extent: 400@500.

and in
ContactListEditor>>closeButtonClick
mainWindow delete

2. What do you want to do ? You can define a new button class which do it but may be overkill.

Button questions:
1. How do you add a button to the Add/Edit/Remove row that will close the ContactListEditor window? I tried adding

builder newButtonFor: self
action: #closeButtonClick
label: 'Close'
help: 'Close this window'.

with a new method
closeButtonClick
self delete.

but that generates a MNU error.

2. How do you code a button that takes one or more parameters when the button is clicked?

My "ContactListEditor allInstances" question appears to be related to garbage collection. The instances are in the array until the system cleans up.

I could not reproduce it. Which version of Pharo ?...

2011-02-28T10:21:44.566-08:00

If I inspect "ContactListEditor allInstances" it shows an empty array.

If I then doit "ContactListEditor open" twice (creating 2 instances), and inspect "ContactListEditor allInstances" again, it shows an array with two entries, as expected.

But if I close one (or both) of the "Contacts" windows, then inspect "ContactListEditor allInstances" again, it still shows two instances.

Are the instances still somewhere and accessible? If not, is there any way to make "ContactListEditor allInstances" report correctly?

Great work! Please continue with videos like this.

I am the type of programmer who wants to make GUI mainly for database records and this is what I was seeking for. Lack of documentation (at least telling where to start and showing the basics ... the rest we can read from the code) is a huge break from starting developing in Smalltalk for many of developers.

Thanks Laurent! I really appreciate your videos. They are very helpful and give enough information to help me to make progress in my Smalltalk code. Keep up the great work please!
