Class TreeModelFilter
public class TreeModelFilter
Class for filtering the visible rows of a base
TreeModel
.
This class allows the underlying TreeModel to be filtered in 2 ways:
setVisibleColumn(DataColumnBoolean)
- designates a boolean data column
in the underlying TreeModel that serves as "visible" marker each row.
If the column's value is true, the row will be visible. If the column's
value is false, the row will not be visible.
setVisibleMethod(TreeModelFilterVisibleMethod)
- designates a special class which
can determine if a given row should be visible.
Once a visible column or method has been set, their is no way of unsetting
it.

TreeModelFilter
protected TreeModelFilter(Handle handle)
For internal use only.
TreeModelFilter
public TreeModelFilter(TreeModel model)
Create a new TreeModelFilter using the given TreeModel as the underlying
data model.
clearCache
public void clearCache()
Clear the filter of any cached iterators. This should almost never be
called.
convertChildPathToPath
public TreePath convertChildPathToPath(TreePath child)
Convert the given child TreePath to a path relative to this filter.
convertPathToChildPath
public TreePath convertPathToChildPath(TreePath path)
Convert the given TreePath to a path relative to the child model.
getModel
public TreeModel getModel()
Return the underlying data model.
getType
public static Type getType()
Retrieve the runtime type used by the GLib library.
handleVisibleFunc
protected boolean handleVisibleFunc(Handle model,
Handle iter)
refilter
public void refilter()
Re-evaluate the visiblity of each row in the underlying data model.
This should be called after changing the values in the underlying data
model.
setVisibleColumn
public void setVisibleColumn(DataColumnBoolean column)
Designate a boolean data column in the underlying TreeModel that will
serve as the "visible" marker for each row. If the column's value is
true, the row will be visible. If the column's value is false, the
row will not be visible.
NOTE: There is no unset method.
setVisibleMethod
public void setVisibleMethod(TreeModelFilterVisibleMethod method)
Designate the given TreeModelFilterVisibleMethod object with the
reponsibility of determining if the rows in the underlying TreeModel
should be visible.
NOTE: There is no unset method.
