I checked the app once again. In fact the source is roughly 12 KByte
big and contains 620 StyleRuns. Well, I stell feel, that this shouldn't
be that slow.
I enhanced the speed by switching to MemoryBlocks from 2,9 secs to
1,2 secs,
but the process is still very slow for a 12 KBytes of String to get
parsed...
I'll drop it all over, since it won't ever be so fast, that I can
reconfigure
the style-runs while the user type - I expect. Or, in other words,
the time
needed to code this isn't in a good relation to the usefulness of the
solution.
And, yes, Charles, the Text property is <> "", since the app set the
text just
one line before the Bold(2,3)=true statement.
Thx for your help!

I modified an app in such a way, that the user is able to add

Then I changed it, so that the app highlights certain syntactical
text items. Give a very
small text of roughly 1 K, the process is fast. Given a text of
roughly 5 KByte, the app roughly
a noticeable amount of time (2 seconds) to show the result.
But why? 5 K Text is very few, roughly 20 StyleRun elemements
shouldn't be too much
too. Moreover, the app 'parses' the text for HTML tags in once
single pass.
Any ideas, how this process could be made faster?
Yes. break the text into multiple paragraph-sized StyledText
objects, then color each.
BTW: Since StyledText failed to do the coloring trick, I used
StyleRuns. Might this
be a problem? StyledText crashed as soon, as I tried to change any
style property
e.g. StyledText.Bold(2,3)=true . RB's StyledText demo worked - but
nothing else.
Are you certain that the Text property is <> ""? I reported such a
problem several months ago. Perhaps you should isolate the problem
and report it.
