Hi!
Does anyone have a smart way to make a scrolled TextView scroll along as text is inserted - if, and only if the TextView is showing the bottom part of the buffer?
I can't find an elegant way to determine whether the TextView is "at the bottom" of the buffer, and to handle the situation when resizing an autowrap TextView causes the last line to split, which in turn causes it to drop out of the bottom position.
I implemented this a long time ago in my LostIRC application, which can be found at http://lostirc.sourceforge.net/. You should see the onScroll and onResize functions in src/gtkmm/TextWidget.cpp.
Hope that helps.
- Morten.
