API reference - Class RelativeProgressNotation used in Ruby API documentation Description: A progress reporter counting progress in relative units Class hierarchy: RelativeProgress » Progress
A relative progress reporter counts from 0 to some maximum value representing 0 to 100 percent completion of a task. The progress can be configured to have a description text, a title and a format. The "inc" method increments the value, the "set" or "value=" methods set the value to a specific value. While one of these three methods is called, they will run the event loop in regular intervals. That makes the application respond to mouse clicks, specifically the Cancel button on the progress bar. If that button is clicked, an exception will be raised by these methods. The progress object must be destroyed explicitly in order to remove the progress status bar. A code example:
p = RBA::RelativeProgress::new("test", 10000000)
begin
10000000.times { p.inc }
ensure
p.destroy
end

Detailed descriptionvoid _createDescription: 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. void _destroyDescription: 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. [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. [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. void _manageDescription: 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. void _unmanageDescription: 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. void createDescription: Ensures the C++ object is created Use of this method is deprecated. Use _create instead void destroyDescription: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead [const] bool destroyed?Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead void format=(string format)Description: sets the output format (sprintf notation) for the progress text Python specific notes:The object exposes a writable attribute 'format'. This is the setter. RelativeProgress incDescription: Increments the progress value [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 [static] new RelativeProgress ptr new(string desc,unsigned long max_value)Description: Creates a relative progress reporter with the given description and maximum value The reported progress will be 0 to 100% for values between 0 and the maximum value. The values are always integers. Double values cannot be used property. Python specific notes:This method is the default initializer of the object [static] new RelativeProgress ptr new(string desc,unsigned long max_value,unsigned long yield_interval)Description: Creates a relative progress reporter with the given description and maximum value The reported progress will be 0 to 100% for values between 0 and the maximum value. The values are always integers. Double values cannot be used property. The yield interval specifies, how often the event loop will be triggered. When the yield interval is 10 for example, the event loop will be executed every tenth call of inc or set. Python specific notes:This method is the default initializer of the object void set(unsigned long value,bool force_yield)Description: Sets the progress value This method is equivalent to value=, but it allows to force the event loop to be triggered. If "force_yield" is true, the event loop will be triggered always, irregardless of the yield interval specified in the constructor. void value=(unsigned long value)Description: Sets the progress value Python specific notes:The object exposes a writable attribute 'value'. This is the setter. |
