Qt 4.0 Progress

Filed under

Qt4 is really progressing well. The only problem at this point is that it still changes a lot even after Beta 2 which originally meant to end the phase of rather radical changes, according to the trolls. But that’s fine. Let them get their APIs sorted out, let them react to the extensive feedback and let them time to do it right.

So what’s new in Qt land since Beta 2? First thing to notice is the introduction of “Plastique", which is, as you certainly suspected already, a Qt-only version of the KDE 3.4 default theme “Pastik”. The clear advantage is that Qt finally has a decently looking style for Linux, which is available even to statically-linked Qt applications.

The next topic is an improvement (at least I suppose it’s new, Maksim wasn’t sure either) regarding tool windows handled by QWorkspace (aka MDIs). The window decoration is now completely under control of QStyle, and it might be possible to implement a bridge in KStyle that maps the current KWin decoration on a KDE Style for MDI Widgets.

Oh yeah, and another one: It will be possible for Qt-only application to make use of at least parts of the KDE icons now. Qt has a standard icon set, which depends on the style. KStyle can map them to KIconLoader, or whatever its equivalent in KDE 4 will be called.
