Hi Jonathan,

If you check users of MenuModel and ListModel in the image, you get a few results that could give you an idea of how to do it. For example:

If you look for users of MenuModel you arrive to EpSelection>>filtersSubMenu, which will lead you to EpSelection>>populateMenu: aMenu. And this leads you to:

EpSelection >> initializeItemsModel

itemsModel��

multiSelection: true;

displayBlock: [ :item | item asMorph ];

childrenBlock: [ :item | self childrenItemsOf: item ];

whenSelectedItemsChanged: [ :selectedItems |��

self refreshEntryContentModelWith: selectedItems.

itemsModel menu: [ :aMenu |��

self selection populateMenu: aMenu ] ].

So apparently, the method #menu: receives a block with a menu as argument, and you have to populate it with elements.

Another way to arrive to the same conclusion is to look for senders of #menu:. There you see for example:

ChangeSorterApplication >> initializeWidgets

�� ...

�� methodsListModel menu: [:menu :shifted | self messageMenu: menu shifted: shifted ].

�� changesListModel menu: [:aMenu :shifted | self changeSetMenu: aMenu shifted: shifted ��].

�� classesListModel menu: [:aMenu :shifted | self classMenu: aMenu shifted: shifted ].

�� ...

Cheers,

Guille

Hello,

I am testing the MenuModel and ListModel widgets. I wanted to create a popup menu and then set it with the ListModel >> menu: method. It runs right but once the listmodel open, when i right click on one item to see the pop-up menu it gives me the error as in the "#error.png" picture.��
Here is my example test (based on not significant data):��

[

menu := MenuModel new.

menu addGroup: [ :group |
group addItem: [ :item |
item name: 'item1';
icon: (self iconNamed: #nautilus);
action: [ anyAction1 ]]];
addGroup: [ :group |
group addItem: [ :item |
item name: 'item2';
icon: (self iconNamed: #smallSaveAs);
action: [ anyAction2��]]];
addGroup: [ :group |
group addItem: [ :item |
item name: 'item3';
icon: (self iconNamed: #smallAuthoringTools);
action: [ anyAction4��]]].

ll := LinkedList new.
ll add: 'value1';
add: 'value2';
add: 'value3';
add: 'value4';
add: 'value5';
yourself.

lm := ListModel new.
lm
items: ll;
title: 'ListModel Menu Test'.
lm menu:menu.
lm openWithSpec.

]

I get that the #cull:cull: message is not understood by my instance of MenuModel but i simply call the #menu: method defined in ListModel. Any ideas on the problem ?��
