[Newbies] [squeak-dev] ColorTranscript howto fake/implement?

[Marcel Taeumel]

Hi, there.

That's not how to use text attributes. There is TextColor for setting a text's color. Try this:

text := Text string: 'text' attribute: (TextColor color: Color red).
Transcript show: text;cr.

Best,
Marcel

Hmmm. Doesn’t seem to work. Eventually opens up an uncountable number of MNU windows

Transcript := TranscriptStream new.

text := Text string: 'text' attribute: (Color red).

Transcript show: text;cr

Hi Lawson,

please find attached a changeset that adds text support to TranscriptStream. You have to replace your transcript with "Transcript := TranscriptStream new".

Best,
Marcel

I’m trying to implement something along the lines of:

ColorTranscript show: ‘text’ withColor: Color red; show: ‘more text’ withColor: Color blue.

All stream classes seem to strip out text attribute information except AttributedTextStream which seems rather incomplete.

I was thinking that I could analyze how the color menu that is accessed via cmd-6 (on the mac) is able to colorize a selection even in a transcript window and so implement the functionality by faking the UI’s steps, but I can’t figure out how to debug the interface and trace though a menu call to see what it actually does.

Any suggestions?

on how to trace the steps to colorize a word via the menu OR on how to implement the functionality directly…

Either/both would be appreciated,

Thanks.


Lawson
