API reference - Class BrowserSource

Notation used in Ruby API documentation

Description: The BrowserDialog's source for "int" URL's

The source object basically acts as a "server" for special URL's using "int" as the scheme. Classes that want to implement such functionality must derive from BrowserSource and reimplement the get method. This method is supposed to deliver a HTML page for the given URL.

Alternatively to implementing this functionality, a source object may be instantiated using the constructor with a HTML code string. This will create a source object that simply displays the given string as the initial and only page.

Public constructors

new BrowserSource ptrnew(string arg1)construct a BrowserSource object with a default HTML string

Detailed description

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

assign

Signature: void assign (const BrowserSource other)

Description: Assigns another object to self

create

Signature: void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

destroy

Signature: void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

destroyed?

Signature: [const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

Use of this method is deprecated. Use _destroyed? instead

dup

Signature: [const] new BrowserSource ptr dup

Description: Creates a copy of self

get

Signature: [virtual] string get (string url)

Description: Get the HTML code for a given "int" URL.

If this method returns an empty string, the browser will not be set to a new location. This allows to implement any functionality behind such links. If the method returns a string, the content of this string is displayed in the HTML browser page.

is_const_object?

Signature: [const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

Use of this method is deprecated. Use _is_const_object? instead

new

Signature: [static] new BrowserSource ptr new (string arg1)

Description: construct a BrowserSource object with a default HTML string

The default HTML string is sent when no specific implementation is provided.

Python specific notes:
This method is the default initializer of the object

new_html

Signature: [static] new BrowserSource ptr new_html (string arg1)

Description: construct a BrowserSource object with a default HTML string

Use of this method is deprecated. Use new instead

Python specific notes:
This method is the default initializer of the object
