The TQAxScriptEngine class provides a wrapper around a script engine.
< p > Every instance of the TQAxScriptEngine class represents an interpreter
for script code in a particular scripting language. The class is usually
not used directly. The < a href = "qaxscript.html" > TQAxScript< / a > and < a href = "qaxscriptmanager.html" > TQAxScriptManager< / a > classes provide
convenient functions to handle and call script code.
< p > Direct access to the script engine is provided through
< a href = "#queryInterface" > queryInterface< / a > ().
< p > < b > Warning:< / b > This class is not available with the bcc5.5 and MingW
compilers.

< h3 class = fn > < a name = "State-enum" > < / a > TQAxScriptEngine::State< / h3 >
< p > The State enumeration defines the different states a script
engine can be in.
< ul >
< li > < tt > TQAxScriptEngine::Uninitialized< / tt > - The script has been created, but not yet initialized
< li > < tt > TQAxScriptEngine::Initialized< / tt > - The script has been initialized, but is not running
< li > < tt > TQAxScriptEngine::Started< / tt > - The script can execute code, but does not yet handle events
< li > < tt > TQAxScriptEngine::Connected< / tt > - The script can execute code and is connected so
that it can handle events
< li > < tt > TQAxScriptEngine::Disconnected< / tt > - The script is loaded, but is not connected to
event sources
< li > < tt > TQAxScriptEngine::Closed< / tt > - The script has been closed.

< h3 class = fn > < a name = "TQAxScriptEngine" > < / a > TQAxScriptEngine::TQAxScriptEngine ( const < a href = "ntqstring.html" > TQString< / a > & language, < a href = "qaxscript.html" > TQAxScript< / a > * script )
< / h3 >
Constructs a TQAxScriptEngine object interpreting script code in < em > language< / em >
provided by the code in < em > script< / em > . This is usually done by the < a href = "qaxscript.html" > TQAxScript< / a >
class when < a href = "qaxscript.html#load" > loading a script< / a > .
< p > Instances of TQAxScriptEngine should always have both a language and a
script.
< h3 class = fn > < a name = "~TQAxScriptEngine" > < / a > TQAxScriptEngine::~TQAxScriptEngine ()
< / h3 >
Destroys the TQAxScriptEngine object, releasing all allocated
resources.
< h3 class = fn > void < a name = "addItem" > < / a > TQAxScriptEngine::addItem ( const < a href = "ntqstring.html" > TQString< / a > & name )
< / h3 >
Registers an item with the script engine. Script code can
refer to this item using < em > name< / em > .
< h3 class = fn > bool < a name = "hasIntrospection" > < / a > TQAxScriptEngine::hasIntrospection () const
< / h3 >
Returns TRUE if the script engine supports introspection;
otherwise returns FALSE.
< h3 class = fn > bool < a name = "isValid" > < / a > TQAxScriptEngine::isValid () const
< / h3 >
< p > Returns TRUE if the script engine has been initialized
correctly; otherwise returns FALSE.
< h3 class = fn > long < a name = "queryInterface" > < / a > TQAxScriptEngine::queryInterface ( const < a href = "ntquuid.html" > TQUuid< / a > & uuid, void ** iface ) const
< / h3 >
Requests the interface < em > uuid< / em > from the script engine object and
sets the value of < em > iface< / em > to the provided interface, or to 0 if
the requested interface could not be provided.
< p > Returns the result of the QueryInterface implementation of the COM
object.
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "scriptLanguage" > < / a > TQAxScriptEngine::scriptLanguage () const
< / h3 >
Returns the scripting language, for example "VBScript",
or "JScript".
< h3 class = fn > void < a name = "setState" > < / a > TQAxScriptEngine::setState ( < a href = "qaxscriptengine.html#State-enum" > State< / a > st )
< / h3 >
Sets the state of the script engine to < em > st< / em > .
Calling this function is usually not necessary.
< h3 class = fn > < a href = "qaxscriptengine.html#State-enum" > State< / a > < a name = "state" > < / a > TQAxScriptEngine::state () const
< / h3 >
Returns the state of the script engine.
