Detailed Description

This list model is commonly used to create a symbol gallery viewing application. This is achieved by applying the list model to a list view or grid view, and displaying the symbol swatch and some relevant information along side it in the view's delegate.

This class is a subclass of QAbstractListModel.

The model returns data for the following roles:

categoryQStringThe category of the search result.CategoryRole
keyQStringThe key of the search result.KeyRole
nameQStringThe name of the search result.NameRole
symbolClassQStringThe symbol class of the search result.SymbolClassRole
tagsQStringListThe tags of the search result.TagsRole
symbolUrlQUrlThe file path of the results' symbol swatch.SymbolUrlRole

The symbolUrl role automatically fetches the symbol swatch for the model. You don't need to call createSwatch manually for this to work. All symbolUrl urls are local files, as such QUrl::toLocalFile() should be used to convert to a string path if desired.
