Porting from widgets to a canvas and switching the rendering framework in a single diff means that there's a lot of (not always related) things going on. But due to the coupling between the two frameworks, splitting it up into two diffs would probably mean extra work and wouldn't be worthwhile. In the future, please try to keep unrelated changes (like game pausing) in their own patches. It's much easier to review five ten-line patches than one thirty-line patch.

Hey, thanks for the review and encouragement.

I got a bit carried away while working on this, I think. I'm not so used to working in a patch-submission workflow so I tend to lump changes together, include whitespace and other trivial modifications in unrelated patches, etc. Newbie mistakes that I will try to discipline myself to avoid :)

I do agree with your suggestions and will work on putting together an updated patch, but my available free time dropped considerably shortly after I submitted this review request so it could be a few days before I have anything new to show.

These vars are all unused in the trunk version. This is mostly what I was referring to when in the patch description I mentioned apparent leftovers from the pre-KDE version of the game.

I referred to the KMines source while restructuring the code, as it has various conceptually similar elements (a grid with square cells that are activated by the user during gameplay, etc.)

Particularly on the cells with T-shaped cable junctions, white pixels often appear at the edge of the pixmap during the rotation animation. I would greatly appreciate any suggestions for how to avoid that happening.
