如何获取表格以显示图像

Question

I am building a table in Seaside (Using VisualAge Smalltalk). I would like to have each table row have an image as well as text data. This what the method looks like:

where PSIni getImageUrl returns the main part of the url . The final url looks like http://www.totallyobjects.com/images/pennstadt//15.jpg

Can anyone point me as to how to get this done please?

 makeData: html usingMethod: aMethod

|tableData headingList methodList|

tableData := self perform: aMethod.
headingList := self headingList.
methodList := self methodList.

html table: [ 
    html tableRow: [ 
        headingList do: [ :each | html 
            tableHeading: each 
        ]
    ].
    tableData do: [ :one |          
        html tableRow: [
            methodList do: [ :each | 
                each = #image ifTrue: [ 
                    html tableData: (self showImageFor: one id using: html)
                ] ifFalse: [ 
                    html tableData: (one perform: each)                        
                ]
            ]
        ]
    ]
]

(self showImageFor: one id using: html) obviously doesn't work. This method looks like this:

showImageFor: anID using: html

html image width: 200; url: PSIni getImageURL, '/', anID printString, '.jpg'

where PSIni getImageUrl returns the main part of the url .

The final url looks like: http://www.totallyobjects.com/images/pennstadt/15.jpg and should result in that image appearing in one element of a table row.

You need to nest the brushes:

html tableData: [ (self showImageFor: one id using: html) ]

It's explained in depth in the book: http://book.seaside.st/book/fundamentals/rendering-components
