Re: [Pharo-users] my mistake on Spec?

March 5, 2018


      I'm trying to understand.
I do not get a DNU with the following. You cannot put row out of nowhere.

defaultSpec
^ SpecLayout composed
          newColumn: [ :col |
            col
                newRow: [ :row |
                                      row
                                       add: #plaintiffsTextInput;
                                       add: #addButtonPlaintiffs ];
              newRow: [ :row |
                 row
                     add: #defendantsTextInput;
                     add: #addButtonDefendants ];
             newRow: [ :row |
                 row
                     add: #thirdPartiesTextInput;
                     add: #addButtonThirdParties ] ];
yourself

Now I do not understand why when I add the next lines I get an error

First implement all the missing methods that you use in the spec class
method.
Then let us know.

Thanks for your help, Stef.
Mistakes remain, but I will try to understand them

I'm doing a pass on your code
OrderedCollection new is better to me than #() asOrderedCollection.
GUI_ListCourtCase new openWithSpec
=> DNU
So I added the first missing method, but you should define the
corresponding methods in the class.

Hi yuri
some feedback before looking into spec.
tab method bodies
then do not use instance variables with uppercase.

Is it enough if I just attach it?
I slightly changed the code, that leads to error: "DoesNotUndestand
#plaintiffsTextInput" .
Now I'm studying Help on Spec in SystemBrowser .

Hi Yuriy
this is difficult to debug remotely. Do you have your code
somewhere?

Hi!
I'm trying to write GUI element with Spec, Pharo6.1x64 on Linux.
Do according to the SpecBooklet.
Finished the fragment, and try do:
ui := GUI_ListCourtCase new openWithSpec . -> #value was sent to
nil.
I look in a debugger and:
openWithSpecLayout: aSpec
    "Build the widget using the spec name provided as argument
and
display
it into a window"
(window value notNil and: [ self needRebuild not ])
        ifTrue: [ "window != nil"
            window value rebuildWithSpecLayout: aSpec ]
        ifFalse: [  "If value = Nil   --> send him a message
???"
            window value: (self defaultWindowModelClass new
model:
self).
            window value openWithSpecLayout: aSpec.
            self takeKeyboardFocus ].
^ window value
