Only composites?
by Under7 on Wednesday 30/May/2007, @09:33
Ok, it's nice to see, how much kwin have grown on the optical side, and there are very usefull things, but, is this all? IIRC there were plans to implement features like the window-handling as seen in ratpoisen(?), ION and wmii, or tabbed windows like fluxbox have them. Also, there were talks about some layer-things, but i don't remeber if this were for kwin or for plasma.

KDE has had "tabbed windows" since the B-II window decoration was created in KDE 2.0. It's one of those nifty features that no one used, so it never really evolved from there. I still think it's kind of neat...

There are other things happening in KWin, it's just not the focus of this article. I have several months of weekly articles still to write before 4.0 comes out, so I need to leave myself some material :)

    BII has nothing to do, with tabbed windows. It's also really ugly, and seems a bit buggy. The advantage of tabs, is the possibility to group windows, but BII does'nt do this, it handle all windows the same, and waste space.

      Well, that depends on how you define tabs. It has window titles that auto-arrange themselves like the tabs on top of folders, assuming they are lined up to be the same size. Tabs are still just a metaphor for the folder tabs you find in the common filing cabinet, and BII's titlebar arrangement fits this requirement. That said, BII is in a pretty bad state of affairs these days...

        I don't think it's really in bad shape. There are a few things that may be improved, but the only real problem I find in it is when the composite extension is enabled. I just noticed this when trying composite on my new laptop, since composite has never really worked on the desktop PC.

        The problem is that BII is the only KWin decoration that can change window shape dynamically, and with composite enabled, the title bar is badly clipped when the window title changes, or it is moved around with shift-click.

        Composite also prevents the titlebar unhide code to work.

        I'll have to find a fix for those problems, but it's not been high priority for me, and I'd have to find out more about how composite works.

    B-II is great, I use it on each of my computers since KDE 2.0 and I hope it will still be there (hopefully improved) in KDE4!

    Not tabbed as in graphical widgets, but tabbed as in functional capabilities with semantic grouping, tagging and scripting. KDE 3.x works well with ion3, by the way, and ion3 provides much of what I wanted that the 3.x series KWin couldn't provide... and I pretty much maxed out the capabilities in terms of scripting and settings for KWin 3.x.

    Personally, I don't really think KDE's default Window Manager really needs to have such advanced capabilities. KDE should just to make sure that the apps work well within the X standards so that they work with alternate window managers that do support such capabilities. After all, dcop and ion3's lua scripting is a heck of a powerful combo I'd hate to give up in KDE4 (other than a transition to dbus).

    Correct me if I'm wrong, but Konqueor is tabbed. I can view any part of Kcontrol (via "settings:/") in one tab, a text file in another, a video in another, a website in another, any part of my filesystem in another,fish://.. in another (and then some) simultaneously.

      Uhm, we're talking about window management, not browsers, here.

Yes, it opens a whole new world of options!

for people with disabilities:
- dim inactive windows
- zoom windows
- apply a negative effect over the whole desktop in real-time.

for usability:
- The real-time Alt+Tab / taskbar thumbnails make it easier to find windows.
- The desktop grid / beryl cube make it much easier to grasp the concept of virtual desktops.
- Subtle shadows and gray-out make windows easier to distinguish (like what's in front)
- The shadows and window open/close effects make it easier for new computer users to grasp the concept of windows in general.

And for speed improvements:
- Windows no longer need to be redrawn when you move them over other windows.
- The desktop takes advantage of your - otherwise idle - graphics card hardware, lowering CPU requirements.

Did I miss anything? :-)

      Arguably KWin already has a lot of those.

        Having some, do'nt mean, having enough.
        There is a wide world of windowmanaging waiting :)
