Subject: Re: [Pharo-project] problem with updating checkBoxes in
morph
Reply-To: [email protected]
=> this is a small exemple of my problem that you can run in your
own image (also available in the class side of UITheme by merging
the 'Polymorph-Widgets' package in the PharoInBox repository) :
exampleProblemUpdatingCheckboxes
"little example to show the problem with the method
#on:send:to:with for a CheckboxMorph :
In this example, when you click on the check box, all the other
checkboxes should be updated and selected.
This works when you click on the checkbox label BUT NOT on the
checkbox button.
"
"self exampleProblemUpdatingCheckboxes"
| builder dialog checkboxes |
checkboxes := OrderedCollection new.
builder := ExampleBuilderMorph new.
dialog := (builder newPluggableDialogWindow: 'Example :')
useDefaultOKButton .
dialog contentMorph: (
dialog newGroupboxForAll: {
checkboxes add:
(dialog newCheckboxFor:
(ValueHolder new contents: false)
getSelected: #contents
setSelected: #contents:
label: '1'
help: '').
checkboxes add:
(dialog newCheckboxFor:
(ValueHolder new contents: false)
getSelected: #contents
setSelected: #contents:
label: '2'
help: '').
checkboxes add:
(dialog newCheckboxFor:
(ValueHolder new contents: false)
getSelected: #contents
setSelected: #contents:
label: '3'
help: '').
}
); model: nil.
checkboxes do: [:each | each on: #click send:
#updateCheckboxes:a:b: to: self withValue: checkboxes ].
builder openModal: dialog.
=> and the method :
updateCheckboxes: collectionOfCheckboxes a:a b:b
collectionOfCheckboxes do: [:each | each buttonMorph selected:
true].

I'm a bit wonder, why you sending a #buttonMorph to checkbox morph,
trying to intercept
a messages?
As to me this is a wrong approach, because you as a user of checkbox,
should not care
about its internals, and speak directly with checkbox public layer ,
but not with its internal components.
