.SH DESCRIPTION
This class is defined in the \fBQt ActiveQt Extension\fR, which can be found in the \fCqt/extensions\fR directory. It is not included in the main TQt API.
.PP
The QAxScript class provides a wrapper around script code.
.PP
Every instance of the QAxScript class represents a piece of scripting code in a particular scripting language. The code is loaded into the script engine using load(). Functions declared in the code can be called using call().
.PP
The script provides scriptEngine() provides feedback to the application through signals. The most important signal is the error() signal. Direct access to the QAxScriptEngine is provided through the scriptEngine() function.
.PP
\fBWarning:\fR This class is not available with the bcc5.5 and MingW compilers.
.SS "Member Type Documentation"
.SH "QAxScript::FunctionFlags"
This FunctionFlags enum describes formatting for function introspection.
.TP
\fCQAxScript::FunctionNames\fR - Only function names are returned.
.TP
\fCQAxScript::FunctionSignatures\fR - Returns the functions with signatures.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QAxScript::QAxScript ( const TQString & name, QAxScriptManager * manager )"
Constructs a QAxScript object called \fIname\fR and registers it with the QAxScriptManager \fImanager\fR. This is usually done by the QAxScriptManager class when loading a script.
.PP
A script should always have a name. A manager is necessary to allow the script code to reference objects in the application. The \fImanager\fR takes ownership of the object.
.SH "QAxScript::~QAxScript ()"
Destroys the object, releasing all allocated resources.
.SH "QVariant QAxScript::call ( const TQString & function, const QVariant & var1 = QVariant ( ), const QVariant & var2 = QVariant ( ), const QVariant & var3 = QVariant ( ), const QVariant & var4 = QVariant ( ), const QVariant & var5 = QVariant ( ), const QVariant & var6 = QVariant ( ), const QVariant & var7 = QVariant ( ), const QVariant & var8 = QVariant ( ) )"
Calls \fIfunction\fR, passing the parameters \fIvar1\fR, \fIvar1\fR, \fIvar2\fR, \fIvar3\fR, \fIvar4\fR, \fIvar5\fR, \fIvar6\fR, \fIvar7\fR and \fIvar8\fR as arguments and returns the value returned by the function, or an invalid QVariant if the function does not return a value or when the function call failed.
.PP
See QAxScriptManager::call() for more information about how to call script functions.
.SH "QVariant QAxScript::call ( const TQString & function, QValueList<QVariant> & arguments )"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Calls \fIfunction\fR passing \fIarguments\fR as parameters, and returns the result. Returns when the script's execution has finished.
.PP
See QAxScriptManager::call() for more information about how to call script functions.
.SH "void QAxScript::entered ()\fC [signal]\fR"
This signal is emitted when a script engine has started executing code.
.SH "void QAxScript::error ( int code, const TQString & description, int sourcePosition, const TQString & sourceText )\fC [signal]\fR"
This signal is emitted when an execution error occured while running a script.
.PP
\fIcode\fR, \fIdescription\fR, \fIsourcePosition\fR and \fIsourceText\fR contain information about the execution error.
.SH "void QAxScript::finished ()\fC [signal]\fR"
This signal is emitted when a script engine has finished executing code.
.SH "void QAxScript::finished ( const QVariant & result )\fC [signal]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
\fIresult\fR contains the script's result. This will be an invalid QVariant if the script has no return value.
.SH "void QAxScript::finished ( int code, const TQString & source, const TQString & description, const TQString & help )\fC [signal]\fR"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
\fIcode\fR, \fIsource\fR, \fIdescription\fR and \fIhelp\fR contain exception information when the script terminated.
.SH "QStringList QAxScript::functions ( FunctionFlags flags = FunctionNames ) const"
Returns a list of all the functions in this script if the respective script engine supports introspection; otherwise returns an empty list. The functions are either provided with full prototypes or only as names, depending on the value of \fIflags\fR.
.PP
See also QAxScriptEngine::hasIntrospection().
.SH "bool QAxScript::load ( const TQString & code, const TQString & language = TQString::null )"
Loads the script source \fIcode\fR written in language \fIlanguage\fR into the script engine. Returns TRUE if \fIcode\fR was successfully entered into the script engine; otherwise returns FALSE.
.PP
If \fIlanguage\fR is empty (the default) it will be determined heuristically. If \fIcode\fR contains the string \fCEnd Sub\fR it will be interpreted as VBScript, otherwise as JScript. Additional scripting languages can be registered using QAxScript::registerEngine().
.PP
This function can only be called once for each QAxScript object, which is done automatically when using QAxScriptManager::load().
.SH "TQString QAxScript::scriptCode () const"
Returns the script's code, or the null-string if no code has been loaded yet.
.PP
See also load().
.SH "QAxScriptEngine * QAxScript::scriptEngine () const"
Returns a pointer to the script engine.
.PP
You can use the object returned to connect signals to the script functions, or to access the script engine directly.
.SH "TQString QAxScript::scriptName () const"
Returns the name of the script.
.SH "void QAxScript::stateChanged ( int state )\fC [signal]\fR"
This signal is emitted when a script engine changes state.
\fIstate\fR can be any value in the QAxScriptEngineState enumeration.
