[英]Adding a header to MultiColumnListModel
I am working with Spec library in Pharo 3 and I have found no way to add a header to a multi column list. 我正在使用Pharo 3中的 Spec库 ,但没有找到将标题添加到多列列表的方法。 However, adding headers is feasible through TreeColumnModel and TreeModel like this: 但是,像这样通过TreeColumnModel和TreeModel添加标头是可行的:
| m col1 col2 |
m := TreeModel new.
m roots: #(#a #b #c #d).
m rootNodeHolder: [ :item |
TreeNodeModel new
content: item;
icon: Smalltalk ui icons smallConfigurationIcon ].
m openWithSpec.
col1 := TreeColumnModel new
displayBlock: [ :node | node content asString ];
headerLabel: 'Character'.
col2 := TreeColumnModel new
displayBlock: [ :node | (Character value: node content asString first asciiValue + 1) asString ];
headerLabel: 'Character +1';
headerIcon: Smalltalk ui icons smallBackIcon.
m
columns: {col1. col2};
acceptDropBlock: [ :transfer :event :source :receiver | self halt ].
col2
headerLabel: 'Character +2';
headerIcon: Smalltalk ui icons smallBackIcon;
displayBlock: [ :node | (Character value: node content asString first asciiValue + 2) asString ].
m rootNodeHolder: [ :item |
TreeNodeModel new
content: (Character value: (item asString first asciiValue + 5)) asSymbol;
icon: Smalltalk ui icons smallFullscreenIcon ].
How could I get a header in the following MultiColumnListModel? 如何在下面的MultiColumnListModel中获得标题?
MultiColumnListModel new
items: {$a. $b. $c. $d. $f.};
displayBlock: [:e | {e asString. e isVowel asString} ];
openWithSpec.
Will this work for you? 这对您有用吗?
model := MultiColumnListModel new
items: { {'Letter'. 'isVowel'.}. $a. $b. $c. $d. $f.};
displayBlock: [:e |
e isArray
ifTrue:[{e first asString. e last asString} ]
ifFalse:[
{e asString. e isVowel asString} ]].
model
whenSelectionChanged:[
model getIndex = 1 ifTrue:[
model setIndex:0].
];
openWithSpec.
