Interfaces

Detailed Description

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 aGtkTreePathindicating the root node for the filter at construction time.

Convenient Construction

gtkTreeModelFilter is the equivalent of gtkTreeModelFilterNew.
