|
|
This is the interface for those who want to add custom data items to the browser tree.
|
|
|
|
The method :py:func:`~createDataItem` is ever called only if :py:func:`~capabilities` return non-zero value.
|
|
There are two occasions when :py:func:`~createDataItem` is called:
|
|
|
|
# to create root items (passed path is empty, parent item is ``None``).
|
|
# to create items in directory structure. For this capabilities have to return at least
|
|
of the following: QgsDataProvider.Dir or QgsDataProvider.File. Passed path is the file
|
|
or directory being inspected, parent item is a valid QgsDirectoryItem
|

Human-readable name of the provider name
|

%End
|
|
|
|
virtual QString dataProviderKey() const;
|
|
%Docstring
|
|
Returns the data provider key (if the data item provider is associated with a data provider),
|
|
the default implementation returns an empty string.
|
|
|
|
.. versionadded:: 3.14
|
|
%End
|
|
virtual int capabilities() const = 0;
|
|
%Docstring
|
|
Returns combination of flags from QgsDataProvider.DataCapabilities

|
%End
|

|
|
virtual QgsDataItem *createDataItem( const QString &path, QgsDataItem *parentItem ) = 0 /Factory/;
|
|
%Docstring
|
|
Create a new instance of :py:class:`QgsDataItem` (or ``None``) for given path and parent item.
|
|
Caller takes responsibility of deleting created items.
|
|
%End
|
|
|
|
virtual QVector<QgsDataItem *> createDataItems( const QString &path, QgsDataItem *parentItem );
|
|
%Docstring
|
|
Create a vector of instances of :py:class:`QgsDataItem` (or ``None``) for given path and parent item.
|
|
Caller takes responsibility of deleting created items.
|
|
%End
|
|
|
|
virtual bool handlesDirectoryPath( const QString &path );
|
|
%Docstring
|
|
Returns ``True`` if the provider will handle the directory at the specified ``path``.
|
|
|
|
If the provider indicates that it will handle the directory, the default creation and
|
|
population of directory items for the path will be avoided and it is left to the
|
|
provider to correctly populate relevant entries for the path.
|
|
|
|
The default implementation returns ``False`` for all paths.
