QDict is a high-level dictionary data type that can be used to store a collection of QObjects. A unique key is associated with only one QObject. The following functions are available: - qdict_new() Create a new QDict - qdict_put() Add a new 'key:object' pair - qdict_get() Get the QObject of a given key - qdict_del() Delete a 'key:object' pair - qdict_size() Return the size of the dictionary - qdict_haskey() Check if a given 'key' exists Some high-level helpers to operate on QStrings and QInts objects are also provided.
