...I'm talking to myself here I c. Stuff
like hating windows seems to have a very
high interest here. Styling apps - not so
much. :(

Anyways, an example of a app that has built
in support for qss, loopy:
http://kde-apps.org/content/show.php/Loopy?content=120880

It would be great if more qt4 apps would
have this support out of the box, this
way we wouldn't have to use the extra
-stylesheet flag every time we want the
stylesheet to be applied. I find it hard
to believe that there isn't need for this
type of discussion tho :S

Not anymore :)

I never tried skinning this way, but this seems to be really promising. With the CSS terminology anyone able to code a website could design is own qt theme.

I'll try this asap...

Indeed, plus you get gradients and cool
stuff css2 does not, css3 does tho, but
when will that hit the market?

Using this technique I skinned dolhin in
a finderish way (just to see if I could):
http://kde-look.org/content/show.php/Haxsder?content=126210
Still workin on it tho :)

There are some downsides tho, you can only
apply the stylesheet to one app with the
-stylesheet flag. One would have to write
a qstyle that loads a stylesheet to have
it globally in all apps (not sure if that
is even desired).

The fullscreen interface in gwenview seems
to be done with qss also :)

Wow, really impressive dolphin !! ;)
I started working on a port of the SL nuala theme, I feel like skinning GTK, for the first time with QT. I started out with the pagefold theme, available here : http://cpansearch.perl.org/src/CBUREL/Qt4-0.60_b1/examples/widgets/stylesheet/qss/. Images used are upper in the hierarchy. Do you know any way to have the CSS3 feature text-shadow ? By the way setting the QSS file with the CSS extension doesn't cause any problems, it's easier to lookat within editors, because of syntax coloring and you can use it in the commandline also. Also, you can set in the control panel the Default applications you want to use, which means you can set up KDE to use dolphin with the stylesheet arg ;).

Thx. Yeah nuala is great indeed, I guess
it's gonna be pretty straightforward
porting it to qss, however, the only thing
I see problems with are the connected
toolbuttons as this is afaik not possible
with qss, (I use bespin for these).

It is a lot like themeing gtk with pixmap
engine indeed, with much more power tho.

The text-shadow feature is not currently
available (very very big sad smiley here)
and I have no idea if planned, same goes
for the box shadow I guess.

Nice to know about the css extensions, it's
pain indeed to always has to click manually
the color coding in kate.

A dude actually pointed this out to me
before that one can change this in the
systemsettings, however, I still use a
launcher on the panel with the stylesheet
flag, I need occasionally to start dolphin
clean without stylesheet to see if a
bug I encounter has to do with qss or
not :)

Nice to see you showing interest. QSS
is great, should get much much more
attention than it's getting.

Thanks for your answers ;) That would be good if we had all the CSS3 features, including the transition ones :D Sadly they're only barely supported on firefox, so QT... I've been skinning the systemsettings, and been getting good results so far, except on the scrollbars. Not really sure about these add-line, sub-line attributes. This is amazing how complete you can skin the tabs, like setting a skin for an only tab, or the very last activated one, or the first non-active one :) Nothing can get wrong this way. Here are some screens to show how it looks like for the moment on Plastik ;) :

Yeah all the css3 features would indeed be
nice!

I agree you have gotten some good results,
I don't see any flaws on a quick glance
except for the scrollbars ofc. I agree,
it took me a while to figure out the
scrollbars also, but it's kinda obvious
once you understand it.

With the add/sub-line you can determine
where the arrow will be, for example:

QScrollBar::add-line:vertical {
subcontrol-position: bottom;
subcontrol-origin: margin;
bottom: 0px;
left: 1px;
}

this places the scrolldown button 0px
from the bottom (usually this is desired)
and 1 px from the left.

then if you want the up button just above
the down button, something like this:

QScrollBar::sub-line:vertical {
subcontrol-position: left bottom;
subcontrol-origin: margin;
bottom: 16px;
left: 1px;
}

this places it 16 from bottom.

then you need ofc create margins for
the scrollbar to have something like
32px for bottom, example:

QScrollBar:vertical {
margin: 0px 0px 34px 0px;
}

Yeah, themeing the tabs is really fun
with qss, you have very much power here.
I remember trying to theme the tabs
nicely within gtk, had to give up every
time :D

Anyways, once again, impressive scrots!

Just found this thread. I have currently upgraded to Qt-4.8.1. I've been hoping to get text-shadow working but it does not appear to work in the latest. Have you tried this with later versions of Qt? How can I find out what CSS3 features/styles are available through QSS? I assumed that the later versions would support text-shadow, transitions etc. I've been trying to set text-shadow for a QLabel but have not had success.

I doubt if they add css3 features to Qt4.... maybe Qt5...
...altho I must say I don't know, but if they add,
I'd suppose they add css3 features to Qt5.

Thanks Robert. I was hoping to use css3 styles (ie text-shadow) in say a QLabel field. Only a subset of styles is supported in that widget. To use the other styles, it appears that QWebView must be used.
