Oh! A bit unorthodox, specially considering the shortcut (CTRL+S) --I was expecting something like ENTER :-)

There is also acceptOnCr :)

But what you can do (and actually what you wanna do) is to accept the text at each keyStroke :)

initializePresenter

self instantiateModels: #(
        textName             TextModel
        labelGreeting    LabelModel
        buttonGreet        ButtonModel
    ).

labelGreeting text: ''.
    buttonGreet label: 'Greet Me!'; disable.

should be turned into:

#initializePresenter

textName := self newTextInput.

labelGreeting := self newLabel.

buttonGreet := self newButton.

Would you please explain the RHS of the statements? I don't understand `self newTextInput`.

It�s equivalent to self instantiateModels: #(textName TextInputFieldModel).

It simply creates a new sub model for you :)

labelGreeting text: ''.

buttonGreet label: 'Greet Me!'; disable.

textName autoAccept: true.

It's certainly no big deal but I'm just curious; any special reason why `autoAccept` doesn't default to true?

That�s actually a good question :)

I guess the answer is historical :)

Hi all,

I'm writing a simple graphical version of the legendary "Hello, world". I have a window with a text field, a button and a label. What I'm trying to do is to make the button (which is initially disabled) enabled upon user entering text. However, it seems that the user first must "Accept" the text for the action to be fired.

Here's some snippets of code:

<code>
initializePresenter
    textName whenTextChanged: [
        buttonGreet enable ].
    buttonGreet action: [
        labelGreeting text: 'Hello, ', textName text, '!'.
        buttonGreet disable ].

initializeWidgets
    self instantiateModels: #(
        textName             TextModel
        labelGreeting    LabelModel
        buttonGreet        ButtonModel
    ).

    labelGreeting text: ''.
    buttonGreet label: 'Greet Me!'; disable.
</code>

What am I doing wrong?

TIA,

PS: I have tried `whenTextChanged` to no avail --it shows the same behaviour.
