It's fine on Qt4, where you know what the backend is at compile time. However, it is probably not possible on Qt5, and this behavior is introduced precisely to take that into account (all the <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">qtcX11*</code> calls are no-op unless it is enabled at compile time and is initialized at runtime).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Also these are not really Qt/X11 code.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
They are not Qt since they are provided by <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">libqtcurve-utils</code> which doesn't link to Qt.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
They are not X11 on OSX since <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">libqtcurve-utils</code> is not linked to X11 on OSX either...</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The Qt/X11 calls are indeed filtered out. The Qt::X11 part is filtered out at initialization time (see <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">qt4/style/qtcurve_plugin.cpp</code>) and the X11(xcb) part is filtered out in <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">libqtcurve-utils</code> (see <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">lib/utils/x11utils.c</code>) which makes all x11 calls no-op when xcb is not found or disabled.</p></pre>

For now it's not possible to build for both Qt4 and Qt5 at the same time, at least not using MacPorts.

So yes, it supposes you have Qt4 and Qt5 installed in parallel and with a bit of 'glue' allowing cmake and other build systems to chose the version on the fly.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Someday we'll have something similar in MacPorts on OS X.</p></pre>

Qt will use a native style by default, but supports the same style plugins as it does on other platforms, which bring the advantage of better (more precise) and more compact layout, without by definition reducing integration with the OS X desktop.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">As such, QtCurve 1.8.14 worked "out of the box" (http://kde-look.org/content/show.php?content=40492, source from http://craigd.wikispaces.com/file/view) and I created a MacPorts port for it (https://trac.macports.org/ticket/44527). With the <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">kde4-workspace</code> port installed, one has almost the full customisation experience, minus everything window-manager related of course, nor full control of window backgrounds (not allowed by Qt and/or OS X).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The current version, which has seen many changes that require X11, was less straightforward to get to work, requiring a considerable collection of small changes.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The brunt of the present patchset consists of making the code in question conditional on the presence of <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">Q_WS_X11</code>, <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">Q_OS_MAC</code>, <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">__MACH__</code> or <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">__APPLE__</code> in non Qt code and <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">APPLE</code> in the cmake files. A few patches introduce functions not available on OS X (getline) or replace them with OS X specifics (<code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">clock_gettime</code> -> <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">mach_absolute_timer</code>, nicely initialised with a dylib constructor function :) ) while others simply ensure that header files are found (or inexistent ones ignored).<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
The only functional guess/change I made is in <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">setOpacityProp()</code>, where I added a <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">w->setWindowOpacity( 0.01 * opacity )</code> for non Q_WS_X11 code, presuming that <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">prop</code> is simply on the 0-100 percentage as exposed in the preferences dialog.</p></pre>
