EditorWindow.py:
+ Added get_tabwidth & set_tabwidth "virtual text" methods, that get/set the
widget's view of what a tab means.
+ Moved TK_TABWIDTH_DEFAULT here from AutoIndent.
+ Renamed Mark's get_selection_index to get_selection_indices (sorry, Mark,
but the name was plain wrong <wink>).
FormatParagraph.py: renamed use of get_selection_index.
AutoIndent.py:
+ Moved TK_TABWIDTH_DEFAULT to EditorWindow.
+ Rewrote set_indentation_params to use new VTW get/set_tabwidth methods.
+ Changed smart_backspace_event to delete whitespace back to closest
preceding virtual tab stop or real character (note that this may require
inserting characters if backspacing over a tab!).
+ Nuked almost references to the selection tag, in favor of using
get_selection_indices. The sole exception is in set_region, for which no
"set_selection" abstraction has yet been agreed upon.
+ Had too much fun using the spiffy new features of the format-paragraph
cmd.
I'm still unsure, but couldn't stand the virtual event trickery so tried a
different sin (adding undo_block_start/stop methods to the Text instance in
EditorWindow.py). Like it or not, it's efficient and works <wink>. Better
idea?
Give the attached a whirl. Even if you hate the implementation, I think
you'll like the results. Think I caught all the "block edit" cmds,
including Format Paragraph, plus subtler ones involving smart indents and
backspacing.
