Description ojt 2010-09-16 12:25:04 UTC 
Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

Add feature to measure angles on screen. Can be angle from horizontal or vertical lines, but also arbitary angles between 3 ponts/2 lines.

Reproducible: Didn't try

Not sure how that would work UI-wise. Windows cannot be rotated arbitrarily.

A thought how you could make a "protractor".

1. Have a protractor icon on the ruler that engages/disengages protractor mode.

2. display 3 dots/crosshairs on the screen, that can be placed there by mouse-clicks (and maybe moved by dragging)

3. ideally, show the lines between  A-B  and B-C  to make angle ABC really obvious.

This might be best done by placing a single transparent window over the entire screen?

Just a thought.

I find it is pretty simple to implement one and I did:

It is simple and should cover most of the use caes.

However, KRuler is a "Ruler". I think measuring the angle is out of the scope of this program.
