Kvantum is an SVG-based theme engine for Qt4 and KDE4, i.e. a program for styling Qt4 applications with SVG images.
Kvantum started as a fork of QuantumStyle, which is not developed anymore but whose author continued his work under another name (https://github.com/DexterMagnific/QSvgStyle). However, apart from the basic logic behind them, they are very different creatures now. In Kvantum, the emphasis is on usability, practicality and elegance.
Kvantum comes with a default dark theme, which should be used alongside the KDE/Qt4 color scheme included in the source and is inspired by the default theme of Enlightenment. Creation of such a theme for KDE was my first reason to make Kvantum but you could make themes with very different looks and feels for it; Kvantum will let you control many aspects of Qt widgets.
Please read the file INSTALL for simple instructions on compilation and installation!
For instructions on how to change configuration or make new themes, please read the files Theme-Config and Theme-Making in the doc folder!
*** Dependencies ***
Qt4 and X11 (development packages for compilation)
*** Notes ***
(1) For updating Kvantum under KDE, first switch to another style, then delete the old library and put the new one in its place (don't paste the latter over the former)!
(2) Each new theme should be accompanied by a KDE or Qt color scheme. Although Kvantum can define non-editable text colors, it relies on the color scheme for the others. It comes with a KDE color scheme as well as a Qt color definition for its default theme.
(3) Kvantum does not provide window decorations. Such jobs are done by the window manager.
(4) QuantumStyle or QSvgSyle themes are NOT compatible with Kvantum, and vice versa.
(5) A Qt5 version will come after a stable version of KDE5 has appeared in the Debian repository.
See ChangeLog inside the source for a more thorough list.

* Whole windows/dialogs are stylable by using of an interior element now. The section [Window] is added for that. (This new feature is used in KvGray on KDE-Look.org.)
* The slider handle will be rotated appropriately when needed if its length and width are different.
* Several fixes.
17 Aug 2014
* Added optional inactive sub-states. They aren't used in the default theme though.
* The slider thickness and also the length and thickness of slider handles can be set now.
* Corrected slider position and groove.
* A more elegant rubber band.
* Don't draw ugly frame shapes or shadows (in Krita, Clementine, etc.).

* Override colors of normal, focused or pressed texts by using #rrggbb strings or valid color names like these under proper sections:
If no (valid) text color is given the color scheme will be used. The default theme shows this change. However, at least in case of view items, some KDE apps may have hard-coded text colors. Please read the updated "Theme-Config.pdf"! (Thanks to "sixsixfive" for the suggestion.)
* Set the text shadow color as #rrggbb too.
* The size of radio buttons and checkboxes can be set now but those on menus will never be bigger than the default size. (Thanks to "Hombremaledico" for the suggestion.)
* Fixed the roundness of horizontal scrollbar grooves.
* Fixed some problems with reasonably thick frames and large text spacings. (Many thanks to "Hombremaledico" for pointing out the last two issues.)

* Toolbar (tool) buttons can be raised and grouped together now. The Glassy theme shows that. (see the second screenshot).
* Tooltip shadows.
