Spec: InputWidget question

I've been trying for several days to get the Spec InputWidget to work as expected. I've been running the "example2" example. If you enter text in the input field and press the "enter" key, then the input text is returned. But, if you click the "Ok" button rather than "enter" key, then the input text field is empty. I've tried to dig into why, but I stymied.

Can someone please help me with this?

Hi Brad,

what pharo version ?

For me, the example does not work at all (Pharo 5 and Pharo 6).

Pressing OK, or pressing the Enter-Key shows a DNU
"MessageNotUnderstood: PluggableTextFieldMorph>>acceptContents"

Hi Brad,

the magic of the OK and Cancel buttons is due to the opening of the UI with openDialogWithSpec (instead of openWithSpec).

There is info on that in the Spec documentation, in the ‘Managing Windows’ chapter (which I finished last week :-) ). You can find a pdf of that chapter here: https://ci.inria.fr/pharo-contribution/view/Books/job/BuildingUIWithSpec/lastSuccessfulBuild/artifact/book-result/ManagingWindow/ManagingWindow.pdf

Re: Spec: InputWidget question

Read the chapter. Being new to Spec, I'm still confused because I don't see clear evidence in the chapter that would fix the problems that are occurring in the InputWidget.

I did, however, read your documentation referring to the TextFieldInputModel example. After reading that, I created a TextPrompterWidget, (which is a direct copy of InputWidget). I changed the super class to DynamicComposableModel. I modified the "initializeWidgets" method, removed the "OK" method, and made a few other small modifications and got the widget to work as expected. I DID have to open the widget with "openDialogWithSpec" as that was the only way to auto-magically get the OK-Cancel toolbar widget. I'd share my code if you want.

Re: Spec: InputWidget question

Apologies for not being clear in my mail. The key is that the UI is being opened as a dialog box, generating the OK and Cancel buttons. All this logic is explained in the section "Opening a dialog box and its configuration options”. This also talks about configuring what to do when these buttons are clicked.
