Detailed Description

A description of the expected file structure of a given package type.

PackageStructure defines what is in a package. This information is used to create packages and provides a way to programatically refer to contents.

An example usage of this class might be:

PackageStructure structure;
structure.addDirectoryDefinition("images", "pics/", i18n("Images"));
QStringList mimetypes;
mimetypes << "image/svg" << "image/png" << "image/jpeg";
structure.setMimetypes("images", mimetypes);
structure.addDirectoryDefinition("scripts", "code/", i18n("Executable Scripts"));
mimetypes.clear();
mimetypes << "text/\*";
structure.setMimetypes("scripts", mimetypes);
structure.addFileDefinition("mainscript", "code/main.js", i18n("Main Script File"));
structure.setRequired("mainscript", true);

One may also choose to create a subclass of PackageStructure and include the setup in the constructor.

Either way, PackageStructure creates a sort of "contract" between the packager and the application which is also self-documenting.
