B4J Question [BANano] What can be used to replace B4X's CSBuilder

[toby]

I'm porting some code from B4A to B4J BANano and it's not recognized in B4J. Is it as designed or there is something wrong with my installation?

[B4X] BCTextEngine / BBCodeView - Text engine + BBCode parser + Rich Text View

Be open minded. This is a cross platform library with several features: - Text drawing engine. - Text layout engine. - BBCode parser. - Two custom views that connect everything: BBCodeView - multiline, scrollable with support for embedded views. BBLabel - lightweight label. - NEW...

I've updated the subject, it's a B4J BANano pwa project, therefore I can't use any regular B4J view, including BBCodeView.

My solution: Use StringBuilder to build text with html tags and assign the text to a SKLabel.

Dim sbDetail As StringBuilder
sbDetail.Initialize
sbDetail.Append($"<p>I am normal</p>"$)
sbDetail.Append($"<p style="color:red;">I am red</p>"$)
sbDetail.Append($"<p style="color:blue;">I am blue</p>"$)
sbDetail.Append($"<p style="font-size:50px;">I am big</p>"$)
SKLabel1.Text=sbDetail
[/CODE]

Other tips

1. Replace CRLF with "<BR>"
2. Replace all Pop's and PopAll's with corresponding html closing tags, such as "</div>", "</p>", "</h3>", etc.

The accepted solution works, but this is just because label.text happens to use javascripts .html() method in this case. It should not be considered the general rule. Angel_s solution is definitely the better one for formatting SKLabels, but if you really want to go beyond the basic components, you should read the chapter on BANanoElement in the booklet (chapter 6).

BANanoElement + B4Js SmartStrings are what make BANano so powerful to make WebApps. The best advice I can give is study the booklet.

Dim myHTML As String = $"
<p>I am normal</p>
<p style="color:red;">I am red</p>
<p style="color:blue;">I am blue</p>
<p style="font-size:50px;">I am big</p>    
"$
        
Private body As BANanoElement
body.Initialize("body")
    
body.Append(myHTML)
