<h1>SIP Specification Files<a class="headerlink" href="#sip-specification-files" title="Permalink to this headline">¶</a></h1>
|
||
|
|
<p>A SIP specification consists of some C/C++ type and function declarations and
|
||
|
|
some directives. The declarations may contain annotations which provide SIP
|
||
|
|
with additional information that cannot be expressed in C/C++. SIP does not
|
||
|
|
include a full C/C++ parser.</p>
|
||
|
|
<p>It is important to understand that a SIP specification describes the Python
|
||
|
|
API, i.e. the API available to the Python programmer when they <tt class="docutils literal"><span class="pre">import</span></tt> the
|
||
|
|
generated module. It does not have to accurately represent the underlying
|
||
|
|
C/C++ library. There is nothing wrong with omitting functions that make
|
||
|
|
little sense in a Python context, or adding functions implemented with
|
||
|
|
handwritten code that have no C/C++ equivalent. It is even possible (and
|
||
|
|
sometimes necessary) to specify a different super-class hierarchy for a C++
|
||
|
|
class. All that matters is that the generated code compiles properly.</p>
|
||
|
|
<p>In most cases the Python API matches the C/C++ API. In some cases handwritten
|
||
|
|
code (see <a class="reference external" href="directives.html#directive-%MethodCode"><tt class="xref docutils literal"><span class="pre">%MethodCode</span></tt></a>) is used to map from one to the other
|
||
|
|
without SIP having to know the details itself. However, there are a few cases
|
||
|
|
where SIP generates a thin wrapper around a C++ method or constructor (see
|
||
|
|
<a class="reference external" href="c_api.html#ref-derived-classes"><em>Generated Derived Classes</em></a>) and needs to know the exact C++ signature. To deal
|
||
|
|
with these cases SIP allows two signatures to be specified. For example:</p>
|
||
|
|
<div class="highlight-python"><pre>class Klass
|
||
|
|
{
|
||
|
|
public:
|
||
|
|
// The Python signature is a tuple, but the underlying C++ signature
|
||
|
|
// is a 2 element array.
|
||
|
|
Klass(SIP_PYTUPLE) [(int *)];
|
||
|
|
%MethodCode
|
||
|
|
int iarr[2];
|
||
|
|
|
||
|
|
if (PyArg_ParseTuple(a0, "ii", &iarr[0], &iarr[1]))
|
||
|
|
{
|
||
|
|
// Note that we use the SIP generated derived class
|
||
|
|
// constructor.
|
||
|
|
Py_BEGIN_ALLOW_THREADS
|
||
|
|
sipCpp = new sipKlass(iarr);
|
||
|
|
Py_END_ALLOW_THREADS
|
||
|
|
}
|
||
|
|
%End
|
||
|
|
};</pre>

<p>Here is a short list of differences between C++ and the subset supported by

SIP that might trip you up.</p>
|

|
<blockquote>
|
||
|
|
<ul class="simple">
|
||
|
|
<li>SIP does not support the use of <tt class="docutils literal"><span class="pre">[]</span></tt> in types. Use pointers instead.</li>
|
||
|
|
<li>A global <tt class="docutils literal"><span class="pre">operator</span></tt> can only be defined if its first argument is a
|
||
|
|
class or a named enum that has been wrapped in the same module.</li>
|
||
|
|
<li>Variables declared outside of a class are effectively read-only.</li>
|
||
|
|
<li>A class’s list of super-classes doesn’t not include any access specifier
|
||
|
|
(e.g. <tt class="docutils literal"><span class="pre">public</span></tt>).</li>

<p>To take an example, <tt class="docutils literal"><span class="pre">QAccel::connectItem()</span></tt> connects an internally generated

signal to a slot. The signal is emitted when the keyboard accelerator is

activated and it has a single integer argument that is the ID of the
|
||
|
|
accelerator. The C++ signature is:</p>
|

|
<div class="highlight-python"><pre>bool connectItem(int id, const QObject *receiver, const char *member);</pre>
|
||
|
|
</div>
|

|
|
<p>The corresponding SIP specification is:</p>
|

<div class="highlight-python"><pre>bool connectItem(int, SIP_RXOBJ_CON, SIP_SLOT_CON(int));</pre>

<h2>Classic Division and True Division<a class="headerlink" href="#classic-division-and-true-division" title="Permalink to this headline">¶</a></h2>
|
||
|
|
<p>SIP supports the <tt class="docutils literal"><span class="pre">__div__</span></tt> and <tt class="docutils literal"><span class="pre">__truediv__</span></tt> special methods (and the
|
||
|
|
corresponding inplace versions) for both Python v2 and v3.</p>
|
||
|
|
<p>For Python v2 the <tt class="docutils literal"><span class="pre">__div__</span></tt> method will be used for both classic and true
|
||
|
|
division if a <tt class="docutils literal"><span class="pre">__truediv__</span></tt> method is not defined.</p>
|
||
|
|
<p>For Python v3 the <tt class="docutils literal"><span class="pre">__div__</span></tt> method will be used for true division if a
|
||
|
|
<tt class="docutils literal"><span class="pre">__truediv__</span></tt> method is not defined.</p>
|
||
|
|
<p>For all versions of Python, if both methods are defined then <tt class="docutils literal"><span class="pre">__div__</span></tt>
|
||
|
|
should be defined first.</p>
