Method: Ruber::AbstractProject#initialize

Defined in:
lib/ruber/project.rb

#initialize(parent, backend, name = nil) ⇒ AbstractProject

Creates a new Project. parent is the projects parent object (derived from Qt::Object); file is the name of the project file, which may already exist or not, while name is the name of the project. name can only be specified if the project file doesn’t exist, otherwise ArgumentError will be raised.

The project file, if existing, must follow the format described in the documentation for YamlSettingsBackend and must contain a :project_name entry under the :general group, otherwise it will be considered invalid. In this case, InvalidProjectFile will be raised.

The new project asks each component to register itself with it, so that project options, project widgets (widgets to be shown in the project’s configuration dialog) and project extensions are added. It also connects to the component_loaded and unloading_component signals of the component manager. The first allow each newly loaded plugin to register itself with the project, while the second allows any unloading plugin to unregister itself.

When the project is created, it’s not active.
