Hi,
If you want to provide a completely executable example, you could use
Gofer. In your case, it would look as in the script below. This could be
used in a fresh Moose image:
Gofer new
smalltalkhubUser: 'Offray' project: 'Ubakye';
package: 'Ubakye';
load.
mainTree := UbakyeNode new.
mainTree becomeDefaultTree.
browser := GLMTabulator new.
browser column: #preview.
browser
act: [:newNode |
newNode := UbakyeNode
header: 'nuevoNodo' body:
''.
mainTree addNode: newNode.]
icon: GLMUIThemeExtraIcons glamorousAdd
entitled: 'Add an item in the collection'.
browser
act: [:b | b entity removeLast. b update ]
icon: GLMUIThemeExtraIcons glamorousRemove
entitled: 'Remove last item from the collection'.
browser
updateOn: GLMItemAdded from: #yourself;
updateOn: GLMItemRemoved from: #yourself.
(browser transmit)
to: #preview;
andShow: [ :a |
a tree
title: mainTree header;
children: [:eachNode | eachNode children ];
format: [:eachNode | eachNode header ].
a text
title: 'Text'].
browser openOn: mainTree.
