[Qgis-developer] Spinbox in offset curve tool - what's it for?

[Andreas Neumann]

Hi,

The parallel line tool works fine at my local installation (master, 
kubuntu).

I agree that the numeric input is not yet ideal (because it can be 
easily overwritten, as Martin discovered). If you have a better idea how 
to allow numeric inputs you are welcome to propose a better approach.

We originally wanted the spinbox to follow the mouse cursor in the map 
canvas (like in Autocad) - but for some reasons this did not work with 
qt across all operating systems. That's why the spinbox is now at the 
bottom left. Maybe this would be easier to implement now with qt5?

It would also be nice to have a keyboard modifier (e.g. ctrl) which 
would make a copy of an existing line, rather than moving the existing line.

Andreas
