/**
|
|
* The XCursorThemeModel class provides a model for all locally installed
|
|
* Xcursor themes, and the KDE/Qt legacy bitmap theme.
|
|
*
|
|
* This class automatically scans the locations in the file system from
|
|
* which Xcursor loads cursors, and creates an internal list of all
|
|
* available cursor themes.
|
|
*
|
|
* The model provides this theme list to item views in the form of a list
|
|
* of rows with two columns; the first column has the theme's descriptive
|
|
* name and its sample cursor as its icon, and the second column contains
|
|
* the theme's description.
|
|
*
|
|
* Additional Xcursor themes can be added to a model after it's been
|
|
* created, by calling addTheme(), which takes QDir as a parameter,
|
|
* with the themes location. The intention is for this function to be
|
|
* called when a new Xcursor theme has been installed, after the model
|
|
* was instantiated.
|
|
*
|
|
* The KDE legacy theme is a read-only entry, with the descriptive name
|
|
* "KDE Classic", and the internal name "#kde_legacy#".
|
|
*
|
|
* Calling defaultIndex() will return the index of the theme Xcursor
|
|
* will use if the user hasn't explicitly configured a cursor theme.
