Hello, everyone!
My patch for Krita is done. It was less than a week to do, so the review and commit process was quite fast (perhaps because the simplicity of the function). So a big thanks for Sven, for the reviews and tips, and Boudewijn, for the commit.
In the wishlist, the problem was specified as simply associate the Delete shortcut to the Clear action in the Edit menu. In a first glance, I saw that the key was bound to another operation. Asking on #krita IRC channel, Sven said that the task was a little more than simply adding a shortcut. You see, to work with shapes (squares, circles, stars, etc) Krita uses the Flake library, thus the application have two different actions, one to deal with pixels and other to deal with shapes. The job was to merge the two actions in one (in this case, the Clear action). I made a little video to show the results:
So, the thing works !:D
See ya later!


THANKS a lot indeed for your patch.
I am sure this improvement will prove really beneficial for all Krita’s users
Best regards,
aiai, great work, this rocks. The fact that the delete button ususally does nothing at all was a huge annoyance with Krita… Thanks!
Cara, 2 surpresas. Acabei de testar o Krita com meu novo tablet e ele é animal (Gimp no more), mas tava sentindo falta desse delete aí. Meu, ainda pra descobrir que foi um brasileiro que arrumou. hehehe… To bem animado de me envolver com o Krita, abraços!
