Tk Source Code

The attached patch makes various changes to the text
widget, amongst which is a first cut at fixing the
long-standing inability of the text widget to interact
correctly with a scrollbar when the text widget
contains very long wrapped lines.

More work is still needed, but this basic patch works
reasonably well for me.

I'd very interested in comments.

(Note: the patch also has a first cut implementation of
a -blockcursor option and a 'replace' subcommand).

smooth scrolling.

Fixed a visual glitch caused by unfortunate overloading of
'-1' exposed by the smooth scrolling code.

Update for version 1.8 of tip.  Resolves the indices vs
chars annoyance based on more feedback.  TIP is now final, I
would say.

Here's a patch which integrates smooth scrolling fully into
the code, so that mousewheel, scan-drag etc are all smooth...

This implements version 1.7 of the TIP, based on extensive
feedback.

Yes another patch, providing a more sensible implementation
of '-count' which also covers the 'how tall does my text
widget need to be' question.

Another update, with some more tests, and adds the +/- N
displaylines capability to index manipulation.

One more version. Now implements 'replace' correctly, and
the 'displayline(start|end)' index offset code.  Only
remaining piece is a good 'blockcursor' implementation.

File Added - 59386: TkTextScroll.patch

One more version.  Cleans up the patch, provides better
documentation, and improves the efficiency of updates
triggered by small insertions or deletions.

File Added - 59313: TkTextScroll.patch

Yet another update.  Fixes embedded windows problem and 
one more test (related to scroll-bar update frequency).

Updated patch for greater efficiency, using the
configure-mask capabilities of Tk.

There is one outstanding bug wrt embedded windows not being
unmapped.  I'm looking into it.

Yet another update; now down to just 3 new test failures,
all of which appear actually to be correct results with the
new code.

Updated patch, now passes all except a few tests (some of
whose results should probably be different now).
