Heh-heh, yes that for loop does look better :-) I'll use that.
Textview is awesome and will save me thousands of lines of code, but not
being able to apply a tag to an iter -- that has been a big drawback for
me. You can discover a tag at an iter, but only apply/remove it to a
range. It would be great to be able to apply a style tag at an iter
(including in a blank line) and then have text inserted their use that tag.
One more suggestion for GTK Textview -- this is about the margin and indent
tags. I found that you can apply those tags anywhere in a line and even
multiple times. So in a 100-char line, you can have chars 33-45 with an
indent of 100px, and chars 63-88 with an indent of -50px, etc. And in
addition various left-margins. When you move the cursor through such a
line, the cursor bounces around like crazy and the line is reformatted back
and forth. I cannot imagine why anyone would want this. Such tags should
only apply to whole lines, and only one indent or left-margin tag per
line. As it is, the applied indent and margin tags are hard to manage and
cause too much trouble.
