TheQAxScriptEngine class provides a wrapper around a script engine.
Every instance of theQAxScriptEngine class represents an interpreter for script code in a particular scripting language. The class is usually not used directly. TheQAxScript andQAxScriptManager classes provide convenient functions to handle and call script code.
Direct access to the script engine is provided throughqueryInterface().
Warning: This class is not available with the bcc5.5 and MingW compilers.
See alsoQAxScript,QAxScriptManager,QAxBase, andActiveQt Framework.
The State enumeration defines the different states a script engine can be in.
| Constant | Value | Description |
|---|---|---|
QAxScriptEngine::Uninitialized | 0 | The script has been created, but not yet initialized |
QAxScriptEngine::Initialized | 5 | The script has been initialized, but is not running |
QAxScriptEngine::Started | 1 | The script can execute code, but does not yet handle events |
QAxScriptEngine::Connected | 2 | The script can execute code and is connected so that it can handle events |
QAxScriptEngine::Disconnected | 3 | The script is loaded, but is not connected to event sources |
QAxScriptEngine::Closed | 4 | The script has been closed. |
Constructs aQAxScriptEngine object interpreting script code inlanguage provided by the code inscript. This is usually done by theQAxScript class whenloading a script.
Instances ofQAxScriptEngine should always have both a language and a script.
Destroys theQAxScriptEngine object, releasing all allocated resources.
Registers an item with the script engine. Script code can refer to this item usingname.
Returns true if the script engine supports introspection; otherwise returns false.
[virtual protected]bool QAxScriptEngine::initialize(IUnknown ** ptr)Reimplemented fromQAxBase::initialize().
Returns true if the script engine has been initialized correctly; otherwise returns false.
Requests the interfaceuuid from the script engine object and sets the value ofiface to the provided interface, or to 0 if the requested interface could not be provided.
Returns the result of the QueryInterface implementation of the COM object.
Returns the scripting language, for example "VBScript", or "JScript".
Sets the state of the script engine tost. Calling this function is usually not necessary.
See alsostate().
Returns the state of the script engine.
See alsosetState().
