<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qscriptenginedebugger.html">QScriptEngineDebugger</a> class provides a QScriptEngine debugger.</p>
<p>The <a href="qscriptenginedebugger.html">QScriptEngineDebugger</a> class provides a debugger that can be embedded into Qt applications that use Qt Script. The debugger enables the application user to inspect the state of the script environment and control script execution.</p>
<p>To attach the debugger to a script engine, call the <a href="qscriptenginedebugger.html#attachTo">attachTo</a>() function.</p>
<pre class="cpp">

      <span class="type">QScriptEngine</span> engine;
      <span class="type"><a href="qscriptenginedebugger.html#QScriptEngineDebugger">QScriptEngineDebugger</a></span> debugger;
      debugger<span class="operator">.</span>attachTo(<span class="operator">&amp;</span>engine);

</pre>
<p>Once the debugger has been attached to a script engine, you can proceed to evaluate scripts as usual, e.g&#x2e; by calling QScriptEngine::evaluate(). The debugger will be triggered when an uncaught exception occurs, or when a <code>debugger</code> statement is encountered in a script. It is also possible to interrupt script evaluation at an arbitrary time by triggering the <a href="qscriptenginedebugger.html#DebuggerAction-enum">InterruptAction</a>. For instance, to start the debugger when script evaluation starts, you trigger the action before you begin to evaluate() the script.</p>
<pre class="cpp">

       debugger<span class="operator">-</span><span class="operator">&gt;</span>action(<span class="type"><a href="qscriptenginedebugger.html#QScriptEngineDebugger">QScriptEngineDebugger</a></span><span class="operator">::</span>InterruptAction)<span class="operator">-</span><span class="operator">&gt;</span>trigger();
       engine<span class="operator">-</span><span class="operator">&gt;</span>evaluate(contents<span class="operator">,</span> fileName);

</pre>
<p>By default, the <a href="qscriptenginedebugger.html#standardWindow">standard debugger window</a> is shown when evaluation is suspended. This can be changed by calling the <a href="qscriptenginedebugger.html#setAutoShowStandardWindow">setAutoShowStandardWindow</a>() function.</p>
<p>The debugger defines a set of <a href="qscriptenginedebugger.html#DebuggerAction-enum">actions</a> that are available, such as stopping execution or printing the contents of a variable. It also provides a set of widgets (components) that display the information available from the debugger and that trigger the actions on request. The actions available are identified by the <a href="qscriptenginedebugger.html#DebuggerAction-enum">DebuggerAction</a> enum, and the widgets are identified by the <a href="qscriptenginedebugger.html#DebuggerWidget-enum">DebuggerWidget</a> enum.</p>
<p>Access to the individual debugger widgets is provided by the <a href="qscriptenginedebugger.html#widget">widget</a>() function. This makes it possible to arrange the widgets in a custom manner. Similarly, the <a href="qscriptenginedebugger.html#action">action</a>() function provides access to the various debugger actions.</p>
<p>The <a href="qscriptenginedebugger.html#createStandardToolBar">createStandardToolBar</a>() function creates a standard toolbar, and the <a href="qscriptenginedebugger.html#createStandardMenu">createStandardMenu</a>() function creates a standard menu; these functions can be useful if you are creating a custom debugger configuration.</p>
<p>The <a href="qscriptenginedebugger.html#evaluationSuspended">evaluationSuspended</a>() signal is emitted when the debugger has suspended script evaluation and entered interactive mode, i.e&#x2e;, the mode in which it accepts input from the user. The <a href="qscriptenginedebugger.html#evaluationResumed">evaluationResumed</a>() signal is emitted when script evaluation is resumed, i.e, when execution control is given back to the script engine. The <a href="qscriptenginedebugger.html#state">state</a>() function returns the debugger's current state.</p>
<p>When calling QScriptEngine::evaluate() it is useful to pass a descriptive script name (file name) as second argument, as this is the name that will be displayed by the debugger in the <a href="qscriptenginedebugger.html#DebuggerWidget-enum">ScriptsWidget</a>; if a name is not passed, the script will be labelled &quot;anonymous&quot;.</p>
<p>When evaluation is suspended, the debugger will also suspend the event loop of the script. In the following snippet, the call to QScriptEngine::evaluate() causes the debugger to be triggered, and the function call does not return until the user has finished interacting with the debugger.</p>
<pre class="cpp">

      engine<span class="operator">.</span>evaluate(<span class="string">&quot;debugger&quot;</span>);

</pre>
<p>When the Qt Script debugger is running, the C++ application itself is not &quot;frozen&quot;. This means that it is possible that more scripts are evaluated, even though the debugger has suspended evaluation of the <b>current</b> script evaluation. For example, a C++ timer might trigger that causes a script function to be called, or the user might click on a button in the main application user interface whose clicked() signal is connected to a script function. This kind of nested evaluation is permitted. The debugger will enter interactive mode for the new script if an exception is thrown or a breakpoint is reached. Note that it will not stop when encountering <code>debugger</code> statements.</p>
<p>Nested evaluation requires some thought when deciding how the debugger is presented to the user; for example, whether a modal dialog is suitable, or whether some parts of the main application user interface should be disabled while the debugger is running.</p>
<p>Debugging inside of a paintEvent() is currently not supported. If you need to debug painting-related script code, that code should be evaluated outside of the C++ paintEvent(), e.g&#x2e; by rendering to an image, like the Context2D and Tetrix Qt Script examples do. This will make the code safe for debugging.</p>
<p>The debugger adds some special properties to the script engine: <code>__FILE__</code> holds the name of the script in which the current evaluation occurs, and <code>__LINE__</code> holds the current line number. These are useful when doing print()-style debugging (the messages appear in the debugger's debug output widget).</p>
<p>The Qt Script Debugger Manual describes how to use the debugger. The Context2D example shows how to integrate the debugger in applications.</p>

<p>Returns a pointer to the instance of the specified standard <i>widget</i>. The widgets available are defined by the <a href="qscriptenginedebugger.html#DebuggerWidget-enum">DebuggerWidget</a> enum.</p>
<p>A main window containing all widgets is returned by <a href="qscriptenginedebugger.html#standardWindow">standardWindow</a>(). If you do not want to use this window, you can fetch the individual widgets with this function. For instance, the code example below shows how to set up a layout containing a <a href="qscriptenginedebugger.html#DebuggerWidget-enum">code window</a> and a <a href="qscriptenginedebugger.html#DebuggerWidget-enum">stack widget</a>.</p>
<pre class="cpp">

      <span class="type">QWidget</span> <span class="operator">*</span>codeWindow <span class="operator">=</span> debugger<span class="operator">-</span><span class="operator">&gt;</span>widget(<span class="type"><a href="qscriptenginedebugger.html#QScriptEngineDebugger">QScriptEngineDebugger</a></span><span class="operator">::</span>CodeWidget);
      <span class="type">QWidget</span> <span class="operator">*</span>stackWidget <span class="operator">=</span> debugger<span class="operator">-</span><span class="operator">&gt;</span>widget(<span class="type"><a href="qscriptenginedebugger.html#QScriptEngineDebugger">QScriptEngineDebugger</a></span><span class="operator">::</span>StackWidget);

      layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(codeWindow);
      layout<span class="operator">-</span><span class="operator">&gt;</span>addWidget(stackWidget);

</pre>
<p>Note that you need to set <a href="qscriptenginedebugger.html#setAutoShowStandardWindow">setAutoShowStandardWindow</a>() to false; if not, the standard window will be shown regardless.</p>
