configure follows by make and sudo make install. First, get kqemu-1.3., unpack it, then run the usual steps.

Next step is to install and use accelerator. You'll see some new stuff in /usr/local/.

I found out that this works well, so just download qemu-0.9. then unpack it to /. QEMU 0.9 comes, among others, in binary package. The motivation is simple: I'd like to have a faster system for filter development. Here are some steps I did to have QEMU 0.9 with accelerator (kqemu) on SUSE 10.2. QEMU version 0.9 is already out for some time, but AFAIK no official package is available for openSUSE Linux 10.2 yet. Otherwise, 4-item list will look odd, as only the last item has different background color. In addition, you may want to put some logic to prevent coloring if the number is item is e.g. You can of course save some microseconds if you cycle the background color while iterating the items. QTreeWidgetItem* item = tree->topLevelItem(i) (for two columns, create a loop for more):įor(int i = 0 i topLevelItemCount() i++) In this case, grouped alternating colors can be achieved using e.g. Multiple column list is often made from QTreeWidget with only top level tree items. QBrush c = ((int)(i/group))&1 ? palette().base() : palette().alternateBase() If your list is an instance of QListWidget, QListView or anything derived from QAbstractItemView, it is very easy to enable the alternating colors, just use alternatingRowColors property.Īlas, for grouped alternating colors for QListWidget, you must do some additional work, e.g. The leftmost list widget has the same white color for all rows, the middle one uses alternating row colors (which looks rather "busy"), and the last one colors every 3 rows. it is not that wide, but rather quite tall, and only consists of one or two columns, sometimes it helps to color not every row but a group of row. However, if your list is rather vertical than horizontal, i.e.
With different color every other row, the table or a long list looks more pleasant and easier to use. So at least the next version of Novell's will be able handle those WPG files.Īlternating row colors is a very common user interface pattern, the most used example is the playlist in Apple iTunes. In related story, thanks to our very own Master Fridrich, libwpg-based WPG importer is going into ooo-build. That's why, in the above screenshot, the gradient is not yet properly rendered in Perfectspot. The reason is because it needs ObjectBoundingMode for QGradient which really simplifies the code. Note that I'm waiting for Qt 4.3 before making a first stable release of Perfectspot (and also libwpg, provided that all image loading support is good enough). Right is the WPG file opened and showed in Perfectspot (the all-around WPG viewer and converter).
Left is the original WPG which I made in Corel Presentations by placing this beautiful windmill in Bremen together with a windmill picture from the clip art. But finally, here is the mandatory click-to-enlarge screenshot:

And I still do not code all possible depth/format yet. It was a bit difficult because raster images are typically compressed using RLE (run-length encoding) and it was not too trivial to decode it. As with other graphics formats such as SVG, PDF, and ODG, WPG allows pixmaps or images to be combined with the vector graphics. Continuing my last year's GSOC, finally I managed to implement support for importing embedded raster images in libwpg.
