规格 - 如何编辑表格的内容

发布于 2025-01-29 20:35:27 字数 114 浏览 1 评论 0原文

我有一个sptablePresenter，我想编辑单元格内容。
在许多框架中，可以直接编辑表格的内容，而无需打开新的组件（对话框或主详细信息样式）。我该如何使用规格执行此操作？

表格和树表中的表格中的一个机制来编辑规格中的字符串列

，可以通过声明列以编辑为编辑来编辑字符串。通过发送OnAcceptedition：，它接收两个参数，即正在编辑的对象和编辑字符串。

以下代码将显示如何完成：

app := SpApplication new.
app useBackend: #Gtk.
 
presenter := SpPresenter new.
presenter application: app.

presenter layout: (SpBoxLayout newTopToBottom
    add: (tablePresenter := presenter newTable);
    yourself).

tablePresenter 
    addColumn: (SpStringTableColumn title: 'R/O' evaluated: #key);
    addColumn: ((SpStringTableColumn 
            title: 'Editable' 
            evaluated: #value)
        beEditable; 
        onAcceptEdition: [ :anAssociation :aString | anAssociation value: aString ];
        yourself).

tablePresenter items: { 1 -> 'One'. 2 -> 'Two'. 3 -> 'Three' }.
    
presenter asWindow 
    title: 'Example editing cells';
    open

这将产生（使用GTK3后端）此输出：

Tables and tree tables in Spec inplement a mechanism to edit string columns in place

in Spec, string columns can be edited by just declaring the column to be editable sending the beEditable message and adding a callback to process the edition by sending onAcceptEdition:, which receives two parameters, the object being editing and the edited string.

The following code will show how this can be done:

app := SpApplication new.
app useBackend: #Gtk.
 
presenter := SpPresenter new.
presenter application: app.

presenter layout: (SpBoxLayout newTopToBottom
    add: (tablePresenter := presenter newTable);
    yourself).

tablePresenter 
    addColumn: (SpStringTableColumn title: 'R/O' evaluated: #key);
    addColumn: ((SpStringTableColumn 
            title: 'Editable' 
            evaluated: #value)
        beEditable; 
        onAcceptEdition: [ :anAssociation :aString | anAssociation value: aString ];
        yourself).

tablePresenter items: { 1 -> 'One'. 2 -> 'Two'. 3 -> 'Three' }.
    
presenter asWindow 
    title: 'Example editing cells';
    open

This will produce (with the Gtk3 backend) this output:
