If I understand correct you just want an action that indents the current 
line, right? I've implemented a small example that illustrates how this 
is done.

The position is always available via the QTextEdit's textCursor(), so 
when the action is triggered, TAB in this case, I:
  - get the cursor
  - store the position
  - move to beginning of the line
  - insert four spaces
  - move back to where I was

Is this what you were looking for?

I don't understand exactly what you mean here... The 
cursorPositionChanged signal is availble in the QTextEdit docs as far as 
I can see.
