Detailed Description

The Action class is an abstract container to deal with scripts like a single standalone script file.

Each action holds a reference to the matching Kross::Interpreter created Kross::Script instance.

The Manager takes care of handling the Action instances application by providing access to ActionCollection containers for those Action instances.

Once you've such a Action instance you're able to perform actions with it like executing scripting code.

Following sample shows "Hello World." executed with the python interpreter:

# Create a new Kross::Action instance.
Kross::Action* action = new Kross::Action(0,"MyFirstScript");
# Set the interpreter we like to use. This could be e.g. "python", "ruby" or "kjs".
action->setInterpreter("python");
# Set the scripting code.
action->setCode("print \"Hello World.\"");
# Execute the scripting code.
action->trigger();

Following sample demonstrates how to execute an external python script file. The script file itself is named "mytest.py" and contains:

# this function got called from within C++
def myfunction(args):
    print "Arguments are: %s" % args
# Import the published QObject's
import MyFirstQObject, MySecondQObject
# Call a slot MyFirstQObject provides.
MyFirstQObject.someSlot("Some string")
# Set a property MySecondQObject provides.
MySecondQObject.someProperty = "Other string"

Then you are able to load the script file, publish QObject instances and let the script do whatever it likes to do:

# Publish a QObject instance for all Kross::Action instances.
Kross::Manager::self().addObject(myqobject1, "MyFirstQObject")
# Create a new Kross::Action instance.
Kross::Action* action = new Kross::Action(0,"MySecondScript");
# Publish a QObject instance only for the Kross::Action instance.
action->addObject(myqobject2, "MySecondQObject");
# Set the script file we like to execute.
action->setFile("/home/myuser/mytest.py");
# Execute the script file.
action->trigger();
# Call the "myfunction" defined in the "mytest.py" python script.
QVariant result = action->callFunction("myfunction", QVariantList()<<"Arg");

Constructor & Destructor Documentation

Action::Action	(	QObject *	parent,
		const QString &	name,
		const QDir &	packagepath = `QDir()`
	)

Constructor.

Parameters

parent	The parent QObject this Action is a child of.
name	The unique name this Action has. It's used e.g. at the Manager to identify the Action. The name is accessible via QObject::objectName .

Deprecated:: since 4.3: pass search path to fromDomElement() and toDomElement()

Definition at line 115 of file action.cpp.

Action::Action	(	QObject *	parent,
		const QUrl &	url
	)

Constructor.

Parameters

parent	The parent QObject this Action is a child of.
url	The URL should point to a valid scripting file. This Action will be filled with the content of the file (e.g. the file is read and code should return its content and it's also tried to determine the interpreter ). Remember to use QUrl c'tor explicitly. The name will be set to url.path()

Parameters

code	The scripting code to evaluate.

Returns: The return value of the evaluation.

Definition at line 439 of file action.cpp.

QString Action::file ( ) const

slot

Returns: the script file that should be executed.

Definition at line 351 of file action.cpp.

void Action::finalize ( )

Finalize the Script instance and frees any cached or still running executions.

Normally there is no need to call this function directly because the Action will take care of calling it if needed.

Definition at line 496 of file action.cpp.

void Kross::Action::finalized ( Kross::Action * )

signal

This signal is emitted once a script finalized.

void Kross::Action::finished ( Kross::Action * )

signal

This signal is emitted after the script got executed.

void Action::fromDomElement ( const QDomElement & element )

Method to read settings from the QDomElement element that contains details about e.g.

the displayed text, the file to execute or the used interpreter.

Todo:: BIC merge

Definition at line 153 of file action.cpp.

void Action::fromDomElement	(	const QDomElement &	element,
		const QStringList &	searchPath
	)

Method to read settings from the QDomElement element that contains details about e.g.

the displayed text, the file to execute or the used interpreter.

Parameters

searchPath List of directories where to search the script if its path is relative First item is given the highest priority.

Definition at line 158 of file action.cpp.

QStringList Action::functionNames ( )

slot

Returns: the list of functionnames.

Definition at line 421 of file action.cpp.

QString Action::iconName ( ) const

slot

Return the name of the icon.

Definition at line 293 of file action.cpp.

bool Action::initialize ( )

Normally there is no need to call this function directly because if will be called internally if needed (e.g. on execute ).

Returns: true if the initialization was successful else false is returned.

Definition at line 448 of file action.cpp.

QString Action::interpreter ( ) const

slot

Returns: the name of the interpreter. Could be for example "python" or "ruby".
