Please help with testing! It’s easy!

November 24, 2009 · Filed under KDiamond, kdegames

If you’re running a current KDE SC 4.4 snapshot (all packages and self-compiled variants are okay), please compile/install KDiamond from kdegames. Start KDiamond, pause the game after some seconds, and unpause it after some seconds.

Please write back (either as a comment to this blog entry, or as a mail to me) what you observe: Normally, pausing should hide all diamonds and display a popup in the top left corner of the board, and after unpausing, you can continue to play the game as usual. But on some systems, the popup will get stuck in the middle of the appearing animation, stay there after unpausing, and the game will not be playable even after the unpausing.

Please also write back if everything works fine on your system, and in any case, include the following information in your report:
1. Which distribution do you run? Which version?
2. If you compiled your Qt and KDE from sources, which branch of Qt did you use, and when did you update KDE the last time?
3. If you installed your Qt and KDE from packages, which repositories did you use?

Update: Thanks to anyone who sent information. I’ve found the root cause of the issue: KStatefulBrush. Silly as it sounds, but usage of KStatefulBrush results in an infinite loop. I’m still puzzled why this problem appeared only for me. The problem is actually a bug in Qt.

Rounding errors

March 30, 2008 · Filed under KDiamond

A long-standing problem in KDiamond was that the lower and right border were thinner than the upper and left one. I finally had a deeper look into this with a special debug theme (big rectangles instead of partly transparent SVG masterpieces) and found that this issue was caused by rounding errors. When converting from a floating-point precision number to an integer numer, the digits after the decimal point are usually cut off. In my case this let all diamonds move to the lower right. The bug is now partially fixed, the rest is virtually invisible.

Meanwhile, a friend of mine has started his first KDE application. Palapeli (located in playground/games) is a jigsaw puzzle game. Unlike the normal jigsaw implementations, you do not have to move the pieces from a list onto a fixed board, but can move the parts freely. We will release a first preview version once we have loading and saving of puzzles, and a proper “New puzzle” dialog. Right now, there are only some command line arguments, so if you want to try Palapeli, make sure to pass something in the “–image” argument. For any further questions, `palapeli –help` is your friend.
