Re: [platform-swt-dev] Problems with published StyledText API & documentation
|
We received feedback from and helped out one person before who implemented
an editor using the LineStyleListener approach. I encourage you to be the
second (known) person! It does seem to be possible <g>.
If you encounter any problems or have questions along the way please post
them on the eclipse.tools newsgroup. We are monitoring it and try to reply
promptly. If you find any bugs or find that things are missing or not
explained well in the StyledText articles please open bug reports.

Thank you for the detailed response. You answered all of my questions
perfectly.

Good advice. This is, indeed, the direction I am taking. The only
problem is that JFace seems to have been designed mostly with the
setStyleRange() API in mind rather than the LineStyleListener API, but
I'm working through it. :)
