[Gambas-user] R: Fitting RichtText into several limited areas

[Rolf-Werner Eilert]

I don't think so, because it describes the wideth of a single line of 
richtext.

Paint.Richtext or Paint.DrawRichtext accept a Height for the textframe, 
but it is practically unused. The function goes on drawing beyond this 
point. This is where you would have to start helping.

Let's see what would be necessary to do what I was looking for, 
something pseudo code:

frameLength = 70 'mm

sRtext = File.Load("myrichtext")

If Paint.RichTextHeight(sRtext) > frameLength Then

     'if it stopped drawing at 70 mm
     Paint.DrawRichText(sRtext, x1, y1, width, frameLength)
   Paint.DrawRichText(RSTring.Mid(sRtext, RichTextLength(sRtext, 
frameLength) + 1, x2, y2, W, frameLength)

     'like it is now, not stopping, with special cutting function
     Paint.DrawRichText(RString.Left(sRtext, RichTextLength(sRtext, 
frameLength)), x1, y1, W, frameLength)
     Paint.DrawRichText(RString.Mid(sRtext, RichTextLength(sRtext, 
frameLength) + 1, x2, y2, W, frameLength)

Else

     Paint.DrawRichText(sRtext, x1, y1, width, frameLength)

Endif


So, this is just phantasy, but does it make it clearer? A class RString 
would be needed, and a function that finds the position of the last 
printable character in a RichText of given width. But I know, catenating 
of these tagged strings would mean interpreting them, it's rather tricky...

Rolf
