Installation

Build and install

mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make
make install

CMake configure arguments

1. ENABLE_QT4:

   Building QtCurve Qt4 theme.

   (Default: On)

2. ENABLE_QT5:

   Building QtCurve Qt5 theme.

   (Default: On)

3. ENABLE_GTK2:

   Building QtCurve Gtk2 theme.

   (Default: On)

4. QTC_ENABLE_X11:

   Enable X11 support. Require xcb, xlib-xcb. Will cause libqtcurve-utils.so to link to libxcb, libX11-xcb and libX11.

   NOTE: this options will not affect any modules/libraries other than libqtcurve-utils.so. libqtcurve-utils.so with/without the option are API and ABI compatible although some functions will be NO-OP with X11 disabled.

   (Default: On)

5. QTC_INSTALL_PO:

   Install *.po translation files.

   (Default: On)

6. QTC_QT4_ENABLE_KDE:

   Compile QtCurve qt4 style with KDE support and dependencies.

   (Default: On)

7. QTC_QT4_ENABLE_KWIN:

   Compile QtCurve qt4 kwin style. This will only have effect when KDE support is turned on. Also require a X11 build of Qt4 and libxcb headers.

   (Default: On if kwin header is found and KDE support is on, Off otherwise)

8. QTC_KDE4_PREFIX:

   The install prefix of KDE4.

   (Default: the value returned by kde4-config or ${CMAKE_INSTALL_PREFIX} if kde4-config is not found.)

9. QTC_KDE4_ICONS_PREFIX:

   The path of KDE4 icons.

   (Default: ${QTC_KDE4_PREFIX}/share/icons)

10. QTC_QT5_ENABLE_KDE:

    Compile QtCurve qt5 style with KDE Frameworks support and dependencies.

    (Default: On)

Deprecated and temporary options.

These compile options were used to turn on/off some experimental features or work around for certain hardware/software/drivers. It is not guaranteed that any of the non-default value of these options can work and some of these options may crash certain applications. They may also be removed at any time (especially the ones to work around old hardware or driver bugs) and are not recommanded to turn on in distribution packages.

1. QTC_QT4_STYLE_SUPPORT:

   Support QtCurve style files. These are stored as <kde prefix>/share/apps/kstyle/themes/qtc_<stylename>.themerc Note that this is not supported in Qt5.

   (Default: Off)

Additional Features

XBar/MacMenu

The XBar support was copied directly from Bespin. The relevant files are named macmenu.*. These were taken from revision 652.

Deprecated in favor of appmenu since KWin has builtin support for that after 4.10 and appmenu-qt does not depend on a certain theme.

Themes

As of v0.55, you can create QtCurve based themes. These will appear with KDE's style control panel's combobox of styles. To create a new theme, select 'QtCurve' from within KDE's style panel, then configure QtCurve as required. After this, in QtCurve's config dialog, select 'Export theme' from the options menu button. You will then be prompted to give your new 'theme' a name, and a comment. QtCurve will then create a file named qtc_<name>.themerc (e.g. qtc_klearlooks.themerc) - this will have the following format:

[Misc]
Name=Klearlooks
Comment=Clearlooks inspired style
[KDE]
WidgetStyle=qtc_klearlooks
[Settings]
animatedProgress=false
appearance=gradient
....rest of qtcurve settings...

To use this theme, either copy qtc_<name>.themerc to $KDEHOME/share/apps/kstyle/themes/ (usually ~/.kde/share/apps/kstyle/themes/) or copy to <kde install prefix>/share/apps/kstyle/themes/ (usually /usr/share/apps/kstyle/themes/)

When KDE's style panel is restarted, your new theme should appear in the list.

NOTE: As of QtCurve 1.0.0 style support has been disabled by default (enable via QTC_QT4_STYLE_SUPPORT) and this is not supported by Qt5.

Testing

As of v1.2.1, QtCurve can be forced to read its settings from an alternate config file via the QTCURVE_CONFIG_FILE environment variable. This is only really useful for testing alternate config settings without changing the users current settings.

Usage:

QTCURVE_CONFIG_FILE=~/testfile kcalc

Compiler versions requirement

QtCurve requires the GNU dialect of ISO C99 and ISO C++11 (which means the compilers have to support -std=gnu99 and -std=c++0x command line option). g++>=4.7 and clang++>=3.3 are fully supported. C compiler for any reasonable version of gcc and clang should all work well.

For g++ older than 4.7, you need -Doverride= in the CXXFLAGS since it does not support the override keyword in c++11. The trick should work down to g++ 4.4 for the Qt4 style and 4.6 for the Qt5 stle.

clang++ 3.3 is not compatible with the stdc++ header shipped with gcc 4.7 so libc++ is required when compiling with clang++ 3.3.
