GtkTreeModelFilter
A GtkTreeModel which hides parts of an underlying tree model
A #GtkTreeModelFilter is a tree model which wraps another tree model,
and can do the following things:
Filter specific rows, based on data from a "visible column", a column
storing booleans indicating whether the row should be filtered or not,
or based on the return value of a "visible function", which gets a
model, iter and user_data and returns a boolean indicating whether the
row should be filtered or not.
Modify the "appearance" of the model, using a modify function.
This is extremely powerful and allows for just changing
some values and also for creating a completely different model based on
the given child model.
Set a different root node, also known as a "virtual root". You can pass in
a #GtkTreePath indicating the root node for the filter at construction time.
#GtkTreeModelSort
The GtkTreeModelFilter struct contains only private fields.
A function which decides whether the row indicated by @iter is visible.
@model: the child model of the #GtkTreeModelFilter
@iter: a #GtkTreeIter pointing to the row in @model whose visibility
is determined
@data: user data given to gtk_tree_model_filter_set_visible_func()
@Returns: Whether the row indicated by @iter is visible.
A function which calculates display values from raw values in the model.
It must fill @value with the display value for the column @column in the
row indicated by @iter.
Since this function is called for each data access, it's not a
particularly efficient operation.
@model: the #GtkTreeModelFilter
@iter: a #GtkTreeIter pointing to the row whose display values are determined
@value: A #GValue which is already initialized for with the correct type for
the column @column.
@column: the column whose display value is determined
@data: user data given to gtk_tree_model_filter_set_modify_func()
