<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So first off, I'd just like to say that I've been meaning to port KNetWalk for a while now, but never really found the time. It's probably my favourite game in the entire module. Thanks for giving it a shot. For the most part things look good.
Normally, I would say that this patch is too big. 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.</pre>

Speaking of which, enabling smooth transformations makes the rotation animations look *much* nicer, but I'm not sure how much more computationally expensive it is. It would take some profiling (that I don't have time to do to ;)) to find out.</pre>

The reason is that QGraphicsView is able to cache the background.
By keeping the overlay as a separate item, that means that the overlay has to be (at least partially) repainted every time one of the items over top of it changes. Since it's basically a part of the background, you might as well stick them together.</pre>

You now have a few classes holding and passing around pointers to a KGameRenderer object, which I don't really love. Getting rid of the singleton is fine if you can cleanly and conveniently keep everyone informed without it, but I'm really not sure that this is an improvement.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Oh, and I had the same issue as Stefan. The initial view was solid white and stayed that way after resizing the window. Only after changing the theme could I get some visuals. Now that I've got them, they seem to be sticking around on subsequent runs, so you might want to look at how you handle the case of an empty cache?
Sorry if that seems like an overwhelming number of complaints. Please don't let it scare you away. :) Really I'm quite pleased with the patch overall.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">As KNetWalk's use of QWidget as its graphics stack was marked in red on the porting status wiki page, and because I wanted to see if I had acquired a good enough working understanding of the QGraphicsView framework to be able to accomplish it, I decided to attempt a full port of this 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.)
Doing this required some rather invasive changes to the GUI code. In addition to switching to QGraphicsView, this patch also:
- Removes the distinction between mouse and keyboard input modes. They now work together nicely, as they should.
- Adds the ability to pause the game, and hide the puzzle while it is paused.
- Cleans up code in various places and removes a number of obsolete class members that I presume to have been vestiges from before the KDE port.
My only disappointment is that switching to QGraphicsView did not get rid of the rendering artifacts that often appear when the cables are being rotated. 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.</pre>
